  • Best Practices Generating WebService Proxies for Oracle Sales Cloud (Fusion CRM)

    - by asantaga
    I've recently been building a REST Service wrapper for Oracle Sales Cloud and initially all was going well, however as soon as I added all of my Web Service proxies I started to get weird errors..  My project structure looks like this What I found out was if I only had the InteractionsService & OpportunityService WebService Proxies then all worked ok, but as soon as I added the LocationsService Proxy, I would start to see strange JAXB errors. Example of the error message Exception in thread "main" javax.xml.ws.WebServiceException: Unable to create JAXBContextat com.sun.xml.ws.model.AbstractSEIModelImpl.createJAXBContext(AbstractSEIModelImpl.java:164)at com.sun.xml.ws.model.AbstractSEIModelImpl.postProcess(AbstractSEIModelImpl.java:94)at com.sun.xml.ws.model.RuntimeModeler.buildRuntimeModel(RuntimeModeler.java:281)at com.sun.xml.ws.client.WSServiceDelegate.buildRuntimeModel(WSServiceDelegate.java:762)at weblogic.wsee.jaxws.spi.WLSProvider$ServiceDelegate.buildRuntimeModel(WLSProvider.java:982)at com.sun.xml.ws.client.WSServiceDelegate.createSEIPortInfo(WSServiceDelegate.java:746)at com.sun.xml.ws.client.WSServiceDelegate.addSEI(WSServiceDelegate.java:737)at com.sun.xml.ws.client.WSServiceDelegate.getPort(WSServiceDelegate.java:361)at weblogic.wsee.jaxws.spi.WLSProvider$ServiceDelegate.internalGetPort(WLSProvider.java:934)at weblogic.wsee.jaxws.spi.WLSProvider$ServiceDelegate$PortClientInstanceFactory.createClientInstance(WLSProvider.java:1039)...... Looking further down I see the error message is related to JAXB not being able to find an objectFactory for one of its types Caused by: java.security.PrivilegedActionException: com.sun.xml.bind.v2.runtime.IllegalAnnotationsException: 6 counts of IllegalAnnotationExceptionsThere's no ObjectFactory with an @XmlElementDecl for the element {http://xmlns.oracle.com/apps/crmCommon/activities/activitiesService/}AssigneeRsrcOrgIdthis problem is related to the following location:at protected javax.xml.bind.JAXBElement com.oracle.xmlns.apps.crmcommon.activities.activitiesservice.ActivityAssignee.assigneeRsrcOrgId at com.oracle.xmlns.apps.crmcommon.activities.activitiesservice.ActivityAssignee This is very strange... My first thoughts are that when I generated the WebService Proxy I entered the package name as "oracle.demo.pts.fusionproxy.servicename" and left the generated types as blank. This way all the generated types get put into the same package hierarchy and when deployed they get merged... Sounds resaonable and appears to work but not in this case..  To resolve this I regenerate the proxy but this time setting : Package name : To the name of my package eg. oracle.demo.pts.fusionproxy.interactionsRoot Package for Generated Types :  Package where the types will be generated to, e.g. oracle.demo.pts.fusionproxy.SalesParty.types When I ran the application now, it all works , awesome eh???? Alas no, there is a serious side effect. The problem now is that to help coding I've created a collection of helper classes , these helper classes take parameters which use some of the "generic" datatypes, like FindCriteria. e.g. This wont work any more public static FindCriteria createCustomFindCriteria(FindCriteria pFc,String pAttributes) Here lies a gremlin of a problem.. I cant use this method anymore, this is because the FindCriteria datatype is now being defined two, or more times, in the generated code for my project. If you leave the Root Package for types blank it will get generated to com.oracle.xmlns, and if you populate it then it gets generated to your custom package.. The two datatypes look the same, sound the same (and if this were a duck would sound the same), but THEY ARE NOT THE SAME... Speaking to development, they recommend you should not be entering anything in the Root Packages section, so the mystery thickens why does it work.. Well after spending sometime with some colleagues of mine in development we've identified the issue.. Alas different parts of Oracle Fusion Development have multiple schemas with the same namespace, when the WebService generator generates its classes its not seeing the other schemas properly and not generating the Object Factories correctly...  Thankfully I've found a workaround Solution Overview When generating the proxies leave the Root Package for Generated Types BLANK When you have finished generating your proxies, use the JAXB tool XJC and generate Java classes for all datatypes  Create a project within your JDeveloper11g workspace and import the java classes into this project Final bit.. within the project dependencies ensure that the JAXB/XJC generated classes are "FIRST" in the classpath Solution Details Generate the WebServices SOAP proxies When generating the proxies your generation dialog should look like this Ensure the "unwrap" parameters is selected, if it isn't then that's ok, it simply means when issuing a "get" you need to extract out the Element Generate the JAXB Classes using XJC XJC provides a command line switch called -wsdl, this (although is experimental/beta) , accepts a HTTP WSDL and will generate the relevant classes. You can put these into a single batch/shell script xjc -wsdl https://fusionservername:443/appCmmnCompInteractions/InteractionService?wsdlxjc -wsdl https://fusionservername443/opptyMgmtOpportunities/OpportunityService?wsdl Create Project in JDeveloper to store the XJC "generated" JAXB classes Within the project folder create a filesystem folder called "src" and copy the generated files into this folder. JDeveloper11g should then see the classes and display them, if it doesnt try clicking the "refresh" button In your main project ensure that the JDeveloper XJC project is selected as a dependancy and IMPORTANT make sure it is at the top of the list. This ensures that the classes are at the front of the classpath And voilà.. Hopefully you wont see any JAXB generation errors and you can use common datatypes interchangeably in your project, (e.g. FindCriteria etc)

  • Exalogic 2.0.1 Tea Break Snippets - Modifying the Default Shipped Template

    - by The Old Toxophilist
    Having installed your Exalogic Virtual environment by default you have a single template which can be used to create your vServers. Although this template is suitable for creating simple test or development vServers it is recommended that you look at creating your own custom vServers that match the environment you wish to build and deploy. Therefore this Tea Time Snippet will take you through the simple process of modifying the standard template. Before You Start To edit the template you will need the Oracle ModifyJeos Utility which can be downloaded from the eDelivery Site. Once the ModifyJeos Utility has been downloaded we can install the rpms onto either an existing vServer or one of the Control vServers. rpm -ivh ovm-modify-jeos-1.0.1-10.el5.noarch.rpm rpm -ivh ovm-template-config-1.0.1-5.el5.noarch.rpm Alternatively you can install the modify jeos packages on a none Exalogic OEL installation or a VirtualBox image. If you are doing this, assuming OEL 5u8, you will need the following rpms. rpm -ivh ovm-modify-jeos-1.0.1-10.el5.noarch.rpm rpm -ivh ovm-el5u2-xvm-jeos-1.0.1-5.el5.i386.rpm rpm -ivh ovm-template-config-1.0.1-5.el5.noarch.rpm Base Template If you have installed the modify onto a vServer running on the Exalogic then simply mount the /export/common/images from the ZFS storage and you will be able to find the el_x2-2_base_linux_guest_vm_template_2.0.1.1.0_64.tgz (or similar depending which version you have) template file. Alternatively the latest can be downloaded from the eDelivery Site. Now we have the Template tgz we will need the extract it as follows: tar -zxvf  el_x2-2_base_linux_guest_vm_template_2.0.1.1.0_64.tgz This will create a directory called BASE which will contain the System.img (VServer image) and vm.cfg (VServer Config information). This directory should be renamed to something more meaning full that indicates what we have done to the template and then the Simple name / name in the vm.cfg editted for the same reason. Modifying the Template Resizing Root File System By default the shipped template has a root size of 4 GB which will leave a vServer created from it running at 90% full on the root disk. We can simply resize the template by executing the following: modifyjeos -f System.img -T <New Size MB>) For example to imcrease the default 4 GB to 40 GB we would execute: modifyjeos -f System.img -T 40960) Resizing Swap We can modify the size of the swap space within a template by executing the following: modifyjeos -f System.img -S <New Size MB>) For example to increase the swap from the default 512 MB to 4 GB we would execute: modifyjeos -f System.img -S 4096) Changing RPMs Adding RPMs To add RPMs using modifyjeos, complete the following steps: Add the names of the new RPMs in a list file, such as addrpms.lst. In this file, you should list each new RPM in a separate line. Ensure that all of the new RPMs are in a single directory, such as rpms. Run the following command to add the new RPMs: modifyjeos -f System.img -a <path_to_addrpms.lst> -m <path_to_rpms> -nogpg Where <path_to_addrpms.lst> is the path to the location of the addrpms.lst file, and <path_to_rpms> is the path to the directory that contains the RPMs. The -nogpg option eliminates signature check on the RPMs. Removing RPMs To remove RPM s using modifyjeos, complete the following steps: Add the names of the RPMs (the ones you want to remove) in a list file, such as removerpms.lst. In this file, you should list each RPM in a separate line. The Oracle Exalogic Elastic Cloud Administrator's Guide provides a list of all RPMs that must not be removed from the vServer. Run the following command to remove the RPMs: modifyjeos -f System.img -e <path_to_removerpms.lst> Where <path_to_removerpms.lst> is the path to the location of the removerpms.lst file. Mounting the System.img For all other modifications that are not supported by the modifyjeos command (adding you custom yum repositories, pre configuring NTP, modify default NFSv4 Nobody functionality, etc) we can mount the System.img and access it directly. To facititate quick and easy mounting/unmounting of the System.img I have put together the simple scripts below. MountSystemImg.sh #!/bin/sh # The script assumes it's being run from the directory containing the System.img # Export for later i.e. during unmount export LOOP=`losetup -f` export SYSTEMIMG=/mnt/elsystem # Make Temp Mount Directory mkdir -p $SYSTEMIMG # Create Loop for the System Image losetup $LOOP System.img kpartx -a $LOOP mount /dev/mapper/`basename $LOOP`p2 $SYSTEMIMG #Change Dir into mounted Image cd $SYSTEMIMG UnmountSystemImg.sh #!/bin/sh # The script assumes it's being run from the directory containing the System.img # Assume the $LOOP & $SYSTEMIMG exist from a previous run on the MountSystemImg.sh umount $SYSTEMIMG kpartx -d $LOOP losetup -d $LOOP Packaging the Template Once you have finished modifying the template it can be simply repackaged and then imported into EMOC as described in "Exalogic 2.0.1 Tea Break Snippets - Importing Public Server Template". To do this we will simply cd to the directory above that containing the modified files and execute the following: tar -zcvf <New Template Directory> <New Template Name>.tgz The resulting.tgz file can be copied to the images directory on the ZFS and uploadd using the IB network. This entry was originally posted on the The Old Toxophilist Site.

  • Breaking 1NF to model subset constraints. Does this sound sane?

    - by Chris Travers
    My first question here. Appologize if it is in the wrong forum but this seems pretty conceptual. I am looking at doing something that goes against conventional wisdom and want to get some feedback as to whether this is totally insane or will result in problems, so critique away! I am on PostgreSQL 9.1 but may be moving to 9.2 for this part of this project. To re-iterate: Does it seem sane to break 1NF in this way? I am not looking for debugging code so much as where people see problems that this might lead. The Problem In double entry accounting, financial transactions are journal entries with an arbitrary number of lines. Each line has either a left value (debit) or a right value (credit) which can be modelled as a single value with negatives as debits and positives as credits or vice versa. The sum of all debits and credits must equal zero (so if we go with a single amount field, sum(amount) must equal zero for each financial journal entry). SQL-based databases, pretty much required for this sort of work, have no way to express this sort of constraint natively and so any approach to enforcing it in the database seems rather complex. The Write Model The journal entries are append only. There is a possibility we will add a delete model but it will be subject to a different set of restrictions and so is not applicable here. If and when we allow deletes, we will probably do them using a simple ON DELETE CASCADE designation on the foreign key, and require that deletes go through a dedicated stored procedure which can enforce the other constraints. So inserts and selects have to be accommodated but updates and deletes do not for this task. My Proposed Solution My proposed solution is to break first normal form and model constraints on arrays of tuples, with a trigger that breaks the rows out into another table. CREATE TABLE journal_line ( entry_id bigserial primary key, account_id int not null references account(id), journal_entry_id bigint not null, -- adding references later amount numeric not null ); I would then add "table methods" to extract debits and credits for reporting purposes: CREATE OR REPLACE FUNCTION debits(journal_line) RETURNS numeric LANGUAGE sql IMMUTABLE AS $$ SELECT CASE WHEN $1.amount < 0 THEN $1.amount * -1 ELSE NULL END; $$; CREATE OR REPLACE FUNCTION credits(journal_line) RETURNS numeric LANGUAGE sql IMMUTABLE AS $$ SELECT CASE WHEN $1.amount > 0 THEN $1.amount ELSE NULL END; $$; Then the journal entry table (simplified for this example): CREATE TABLE journal_entry ( entry_id bigserial primary key, -- no natural keys :-( journal_id int not null references journal(id), date_posted date not null, reference text not null, description text not null, journal_lines journal_line[] not null ); Then a table method and and check constraints: CREATE OR REPLACE FUNCTION running_total(journal_entry) returns numeric language sql immutable as $$ SELECT sum(amount) FROM unnest($1.journal_lines); $$; ALTER TABLE journal_entry ADD CONSTRAINT CHECK (((journal_entry.running_total) = 0)); ALTER TABLE journal_line ADD FOREIGN KEY journal_entry_id REFERENCES journal_entry(entry_id); And finally we'd have a breakout trigger: CREATE OR REPLACE FUNCTION je_breakout() RETURNS TRIGGER LANGUAGE PLPGSQL AS $$ BEGIN IF TG_OP = 'INSERT' THEN INSERT INTO journal_line (journal_entry_id, account_id, amount) SELECT NEW.id, account_id, amount FROM unnest(NEW.journal_lines); RETURN NEW; ELSE RAISE EXCEPTION 'Operation Not Allowed'; END IF; END; $$; And finally CREATE TRIGGER AFTER INSERT OR UPDATE OR DELETE ON journal_entry FOR EACH ROW EXECUTE_PROCEDURE je_breaout(); Of course the example above is simplified. There will be a status table that will track approval status allowing for separation of duties, etc. However the goal here is to prevent unbalanced transactions. Any feedback? Does this sound entirely insane? Standard Solutions? In getting to this point I have to say I have looked at four different current ERP solutions to this problems: Represent every line item as a debit and a credit against different accounts. Use of foreign keys against the line item table to enforce an eventual running total of 0 Use of constraint triggers in PostgreSQL Forcing all validation here solely through the app logic. My concerns are that #1 is pretty limiting and very hard to audit internally. It's not programmer transparent and so it strikes me as being difficult to work with in the future. The second strikes me as being very complex and required a series of contraints and foreign keys against self to make work, and therefore it strikes me as complex, hard to sort out at least in my mind, and thus hard to work with. The fourth could be done as we force all access through stored procedures anyway and this is the most common solution (have the app total things up and throw an error otherwise). However, I think proof that a constraint is followed is superior to test cases, and so the question becomes whether this in fact generates insert anomilies rather than solving them. If this is a solved problem it isn't the case that everyone agrees on the solution....

  • Right-Time Retail Part 2

    - by David Dorf
    This is part two of the three-part series. Normal 0 false false false EN-US X-NONE X-NONE /* Style Definitions */ table.MsoNormalTable {mso-style-name:"Table Normal"; mso-tstyle-rowband-size:0; mso-tstyle-colband-size:0; mso-style-noshow:yes; mso-style-priority:99; mso-style-qformat:yes; mso-style-parent:""; mso-padding-alt:0in 5.4pt 0in 5.4pt; mso-para-margin-top:0in; mso-para-margin-right:0in; mso-para-margin-bottom:10.0pt; mso-para-margin-left:0in; line-height:115%; mso-pagination:widow-orphan; font-size:11.0pt; font-family:"Calibri","sans-serif"; mso-ascii-font-family:Calibri; mso-ascii-theme-font:minor-latin; mso-fareast-font-family:"Times New Roman"; mso-fareast-theme-font:minor-fareast; mso-hansi-font-family:Calibri; mso-hansi-theme-font:minor-latin; mso-bidi-font-family:"Times New Roman"; mso-bidi-theme-font:minor-bidi;} Right-Time Integration Of course these real-time enabling technologies are only as good as the systems that utilize them, and it only takes one bottleneck to slow everyone else down. What good is an immediate stock-out notification if the supply chain can’t react until tomorrow? Since being formed in 2006, Oracle Retail has been not only adding more integrations between systems, but also modernizing integrations for appropriate speed. Notice I tossed in the word “appropriate.” Not everything needs to be real-time – again, we’re talking about Right-Time Retail. The speed of data capture, analysis, and execution must be synchronized or you’re wasting effort. Unfortunately, there isn’t an enterprise-wide dial that you can crank-up for your estate. You’ll need to improve things piecemeal, with people and processes as limiting factors while choosing the appropriate types of integrations. There are three integration styles we see in the retail industry. First is batch. I know, the word “batch” just sounds slow, but this pattern is less about velocity and more about volume. When there are large amounts of data to be moved, you’ll want to use batch processes. Our technology of choice here is Oracle Data Integrator (ODI), which provides a fast version of Extract-Transform-Load (ETL). Instead of the three-step process, the load and transform steps are combined to save time. ODI is a key technology for moving data into Retail Analytics where we can apply science. Performing analytics on each sale as it occurs doesn’t make any sense, so we batch up a statistically significant amount and submit all at once. The second style is fire-and-forget. For some types of data, we want the data to arrive ASAP but immediacy is not necessary. Speed is less important than guaranteed delivery, so we use message-oriented middleware available in both Weblogic and the Oracle database. For example, Point-of-Service transactions are queued for delivery to Central Office at corporate. If the network is offline, those transactions remain in the queue and will be delivered when the network returns. Transactions cannot be lost and they must be delivered in order. (Ever tried processing a return before the sale?) To enhance the standard queues, we offer the Retail Integration Bus (RIB) to help the management and monitoring of fire-and-forget messaging in the enterprise. The third style is request-response and is most commonly implemented as Web services. This is a synchronous message where the sender waits for a response. In this situation, the volume of data is small, guaranteed delivery is not necessary, but speed is very important. Examples include the website checking inventory, a price lookup, or processing a credit card authorization. The Oracle Service Bus (OSB) typically handles the routing of such messages, and we’ve enhanced its abilities with the Retail Service Backbone (RSB). To better understand these integration patterns and where they apply within the retail enterprise, we’re providing the Retail Reference Library (RRL) at no charge to Oracle Retail customers. The library is composed of a large number of industry business processes, including those necessary to support Commerce Anywhere, as well as detailed architectural diagrams. These diagrams allow implementers to understand the systems involved in integrations and the specific data payloads. Furthermore, with our upcoming release we’ll be providing a new tool called the Retail Integration Console (RIC) that allows IT to monitor and manage integrations from a single point. Using RIC, retailers can quickly discern where integration activity is occurring, volume statistics, average response times, and errors. The dashboards provide the ability to dive down into the architecture documentation to gather information all the way down to the specific payload. Retailers that want real-time integrations will also need real-time monitoring of those integrations to ensure service-level agreements are maintained. Part 3 looks at marketing.

  • The Best BPM Journey: More Exciting Destinations with Process Accelerators

It was interesting to hear definite patterns emerging from those conversations: “BPM is a journey”, “experiences to share”, “our organization now understands what BPM is”, and my favorite (with some caveats): “BPM is like wine tasting, once you start, you want to try more”. These customers have started their journey, climbed up the learning curve, and reached a vantage point that allows them to see their next BPM destination. They see the next few processes they are going to tackle and improve with BPM. These processes/destinations target both horizontal processes where BPM replaces or coordinates manual activities, and critical industry processes that the company needs to improve to compete and deliver increasing value. Each new destination generates value, allowing the organization to reduce the cost of manual processes that were not supported by apps/custom development, and increase efficiency of end-to-end processes partially covered by apps/custom dev. The question we wanted to answer is how to help organizations experience deeper success with BPM, by increasing their awareness of the potential for reaching new targets, and equipping them with the right tools. We decided that we needed to identify destinations, and plot routes to show the fastest path to those destinations. In the end we want to enable customers to reach “Process Excellence”: continuously set new targets and consistently and efficiently reach them. The result is Oracle Process Accelerators (PA), solutions built using the rich functionality in Oracle BPM Suite. PAs offers a rapidly expanding list of exciting destinations. Our launch of the latest installment of Process Accelerators at Oracle Open World includes new Industry-focused solutions such as Public Sector Incident Reporting and Financial Services Loan Origination, and improved other horizontal PAs, including Travel Request Management, Document Routing and Approval, and Internal Service Requests. Just before OOW we had extended the Oracle deployment of Travel Request Management, riding the enthusiastic response from early adopters among travelers (employees), management and support (approvers). “Getting there first” means being among the first to extract value from the PA approach, while acquiring deeper insights into the customers’ perspective. This is especially noteworthy when it comes to PAs, a set of solutions designed to be quickly deployed and iteratively improved by customers. The OOW launch has generated immediate feedback from customers, non-customers, analysts, and partners. They all confirmed that both Business and IT at organizations benefit from PAs when it comes to exploring the potential for BPM to improve their business processes. PAs help customers visualize what can be done with BPM, and PAs are made to be extended: you can see your destination, change the path to fit your needs, and deploy. We're discovering new destinations/processes that the market wants us to support, generic enough across industries and within industries. We'll keep on building sets of requirements, deliver functional design, construct solutions using Oracle BPM, and test them not only functionally but for performance, scalability, clustering, making them robust, product-quality. Delivering BPM solutions with product-grade quality is the equivalent of following a tried-and-tested path on a map. Do you know of existing destinations in your industry? If yes, we can draw a path to innovative processes together.

  • FILESTREAM/FILETABLE Clarifications for Implementation

    - by user1209734
    Recently our team was looking at FILESTREAM to expand the capabilities of our proprietary application. The main purpose of this app is managing the various PDFS, Images and documents to all of the parts we manufacture. Our ASP application uses a few third party tools to allow viewing of these files. We currently have 980GB of data on the Fileserver. We have around 200GB of Binary data in SQL Server that we would like to extract since it is not performing well hence FILESTREAM seems to be a good compromise to the two major data storage/access issues. A few things are not exactly clear to us: FILESTREAM Can or Cannot store its data on a drive that is not locally attached. We already have a File Server with a RAID 10 (1.5TB drives). This server stores all of the documents right now, would we have to move these drives to the SQL Server for FILESTREAM? That would be a tough bullet to bite since the server also is doubling as the Application Server (Two VMs on one physical server). FILETABLE stores the common metadata about the files but where is the Full Text part of it stored to allow searching of files like doc/docx? Is this separate? Are you able to freely add criteria to this to search by? If so any links to clarify would be appreciated. Can FILETABLE be referenced in another table with a foreign key? Thank you in advance EDIT: For those having these questions this web video covered everything and more in terms of explaining filestream from 2008 to 2012 and the cavets to consider (I would seriously rep him if I could): http://channel9.msdn.com/Events/TechDays/Techdays-2012-the-Netherlands/2270 In conclusion we will not be using FILESTREAM as it would be way to huge of an upsurge to accommodate for investment. EDIT 2: Update to #1 - After carefully assessing FileTable in addition to FILESTREAM we got a winning combination. We did have to move the files over to the new server (wasn't to painful since they were on the same VM).It honestly took more time to write an extraction tool to dump the binary data within SQL to the File System. Update to #2 - This was seperate but again Bob had an excellent webinar explaining this: http://channel9.msdn.com/Events/TechEd/Europe/2012/DBI411 Update to #3 - Using TFT inheritance we recycled the Docs table we had (minus the huge binary blobs) which required very little changes in our legacy apps. This was a huge upshot for the developer team.

  • PostgreSQL to Data-Warehouse: Best approach for near-real-time ETL / extraction of data

    - by belvoir
    Background: I have a PostgreSQL (v8.3) database that is heavily optimized for OLTP. I need to extract data from it on a semi real-time basis (some-one is bound to ask what semi real-time means and the answer is as frequently as I reasonably can but I will be pragmatic, as a benchmark lets say we are hoping for every 15min) and feed it into a data-warehouse. How much data? At peak times we are talking approx 80-100k rows per min hitting the OLTP side, off-peak this will drop significantly to 15-20k. The most frequently updated rows are ~64 bytes each but there are various tables etc so the data is quite diverse and can range up to 4000 bytes per row. The OLTP is active 24x5.5. Best Solution? From what I can piece together the most practical solution is as follows: Create a TRIGGER to write all DML activity to a rotating CSV log file Perform whatever transformations are required Use the native DW data pump tool to efficiently pump the transformed CSV into the DW Why this approach? TRIGGERS allow selective tables to be targeted rather than being system wide + output is configurable (i.e. into a CSV) and are relatively easy to write and deploy. SLONY uses similar approach and overhead is acceptable CSV easy and fast to transform Easy to pump CSV into the DW Alternatives considered .... Using native logging (http://www.postgresql.org/docs/8.3/static/runtime-config-logging.html). Problem with this is it looked very verbose relative to what I needed and was a little trickier to parse and transform. However it could be faster as I presume there is less overhead compared to a TRIGGER. Certainly it would make the admin easier as it is system wide but again, I don't need some of the tables (some are used for persistent storage of JMS messages which I do not want to log) Querying the data directly via an ETL tool such as Talend and pumping it into the DW ... problem is the OLTP schema would need tweaked to support this and that has many negative side-effects Using a tweaked/hacked SLONY - SLONY does a good job of logging and migrating changes to a slave so the conceptual framework is there but the proposed solution just seems easier and cleaner Using the WAL Has anyone done this before? Want to share your thoughts?

  • Existing web-site CSS replacement (re-skinning) best-practices without changing the HTML

    - by Enigmativity
    I can see a number of other good answers to questions relating to CSS best-practices on stack overflow: How to Manage CSS Explosion CSS Conventions / Code Layout Models Are there any CSS standards that I should follow while writing my first stylesheet? What is the best method for tidying CSS? Best Practices - CSS Stylesheet Formatting But I think I have a different problem. I'm trying to "re-skin" an existing site that has been nicely built using div's and ul's, etc, and it has a good existing CSS file, but when I start making changes to the CSS I quickly find that I break the layout. My feeling is that it is very hard to get a feel for how all the CSS will work together and indeed what CSS is affecting parent and sibling elements in the HTML. So, my question is "what are the best-practices around re-skinning an existing web-site by replacing the CSS only and not modifying the existing HTML?" I can't change the classes, ids, node hierarchy, etc. An example of the particular site that I am trying to re-skin is http://demo.nopcommerce.com/. The existing CSS can be as complicated/detailed as this extract from the main CSS file: .header-selectors-wrapper { text-align: right; float: right; width: 500px; } .header-currencyselector { float: right; } .header-languageselector { float: left; } .header-taxDisplayTypeSelector { float: right; } .header-links-wrapper { float: right; text-align: right; width: 570px; } .header-links { border: solid 1px #9a9a9a; padding: 5px 5px 5px 5px; margin-bottom: 5px; display: inline-table; } .order-summary-content .cart .cart-item-row td, .wishlist-content .cart .cart-item-row td { border-bottom: 1px solid #c5c5c5; vertical-align: middle; line-height: 30px; } .order-summary-content .cart .cart-item-row td.product, .wishlist-content .cart .cart-item-row td.product { text-align: left; padding: 0px 10px 0px 10px; } .order-summary-content .cart .cart-item-row td.product a, .wishlist-content .cart .cart-item-row td.product a { font-weight: bold; } Any help would be appreciated.

  • Problems with office automation in asp.net. I can use alternatives such as open-office, if I knew ho

    - by Vinicius Melquiades
    I have a ASP.NET 2.0 web application that should upload a ppt file and then extract its slides to images. For that I have imported office.dll and Microsoft.Office.Interop.PowerPoint.dll assemblies and wrote the following code public static int ExtractImages(string ppt, string targetPath, int width, int height) { var pptApplication = new ApplicationClass(); var pptPresentation = pptApplication.Presentations.Open(ppt, MsoTriState.msoTrue, MsoTriState.msoFalse, MsoTriState.msoFalse); var slides = new List<string>(); for (var i = 1; i <= pptPresentation.Slides.Count; i++) { var target = string.Format(targetPath, i); pptPresentation.Slides[i].Export(target, "jpg", width, height); slides.Add(new FileInfo(target).Name); } pptPresentation.Close(); return slides.Count; } If I run this code in my local machine, in asp.net or a executable, it runs perfectly. But If I try running it in the production server, I get the following error: System.Runtime.InteropServices.COMException (0x80004005): PowerPoint could not open the file. at Microsoft.Office.Interop.PowerPoint.Presentations.Open(String FileName, MsoTriState ReadOnly, MsoTriState Untitled, MsoTriState WithWindow) at PPTImageExtractor.PptConversor.ExtractImages(String caminhoPpt, String caminhoDestino, Int32 largura, Int32 altura, String caminhoThumbs, Int32 larguraThumb, Int32 alturaThumb, Boolean geraXml) at Upload.ProcessRequest(HttpContext context) The process is running with the user NT AUTHORITY\NETWORK SERVICE. IIS is configured to use anonymous authentication. The anonymous user is an administrator, I set it like this to allow the application to run without having to worry about permissions. In my development machine I have office 2010 beta1. I have tested with the executable in a pc with office 2007 as well. And if I run the code from the executable in the server, with office 2003 installed, it runs perfectly. To ensure that there wouldn't be any problems with permissions, everyone in the server has full access to the web site. The website is running in IIS7 and Classic Mode. I also heard that Open-office has an API that should be able to do this, but I couldn't find anything about it. I don't mind using DLLImport to do what I have to do and I can install open-office on the web server. Don't worry about rewriting this method, as long as the parameters are the same, everything will work. I appreciate your help. ps: Sorry for bad English.

  • Injecting generics with Guice

    - by paradigmatic
    I am trying to migrate a small project, replacing some factories with Guice (it is my first Guice trial). However, I am stuck when trying to inject generics. I managed to extract a small toy example with two classes and a module: import com.google.inject.Inject; public class Console<T> { private final StringOutput<T> out; @Inject public Console(StringOutput<T> out) { this.out = out; } public void print(T t) { System.out.println(out.converter(t)); } } public class StringOutput<T> { public String converter(T t) { return t.toString(); } } import com.google.inject.AbstractModule; import com.google.inject.Guice; import com.google.inject.Injector; import com.google.inject.TypeLiteral; public class MyModule extends AbstractModule { @Override protected void configure() { bind(StringOutput.class); bind(Console.class); } public static void main(String[] args) { Injector injector = Guice.createInjector( new MyModule() ); StringOutput<Integer> out = injector.getInstance(StringOutput.class); System.out.println( out.converter(12) ); Console<Double> cons = injector.getInstance(Console.class); cons.print(123.0); } } When I run this example, all I got is: Exception in thread "main" com.google.inject.CreationException: Guice creation errors: 1) playground.StringOutput<T> cannot be used as a key; It is not fully specified. at playground.MyModule.configure(MyModule.java:15) 1 error at com.google.inject.internal.Errors.throwCreationExceptionIfErrorsExist(Errors.java:354) at com.google.inject.InjectorBuilder.initializeStatically(InjectorBuilder.java:152) at com.google.inject.InjectorBuilder.build(InjectorBuilder.java:105) at com.google.inject.Guice.createInjector(Guice.java:92) I tried looking for the error message, but without finding any useful hints. Further on the Guice FAQ I stumble upon a question about how to inject generics. I tried to add the following binding in the configure method: bind(new TypeLiteral<StringOutput<Double>>() {}).toInstance(new StringOutput<Double>()); But without success (same error message). Can someone explain me the error message and provide me some tips ? Thanks.

  • How do I verify a DKIM signature in PHP?

    - by angrychimp
    I'll admit I'm not very adept at key verification. What I have is a script that downloads messages from a POP3 server, and I'm attempting to verify the DKIM signatures in PHP. I've already figured out the body hash (bh) validation check, but I can't figure out the header validation. http://www.dkim.org/specs/rfc4871-dkimbase.html#rfc.section.6.1.3 Below is an example of my message headers. I've been able to use the Mail::DKIM package to validate the signature in Perl, so I know it's good. I just can't seem to figure out the instructions in the RFC and translate them into PHP code. DomainKey-Signature: q=dns; a=rsa-sha1; c=nofws; s=angrychimp-1.bh; d=angrychimp.net; h=From:X-Outgoing; b=RVkenibHQ7GwO5Y3tun2CNn5wSnooBSXPHA1Kmxsw6miJDnVp4XKmA9cUELwftf9 nGiRCd3rLc6eswAcVyNhQ6mRSsF55OkGJgDNHiwte/pP5Z47Lo/fd6m7rfCnYxq3 DKIM-Signature: v=1; a=rsa-sha1; d=angrychimp.net; s=angrychimp-1.bh; c=relaxed/simple; q=dns/txt; [email protected]; t=1268436255; h=From:Subject:X-Outgoing:Date; bh=gqhC2GEWbg1t7T3IfGMUKzt1NCc=; b=ZmeavryIfp5jNDIwbpifsy1UcavMnMwRL6Fy6axocQFDOBd2KjnjXpCkHxs6yBZn Wu+UCFeAP+1xwN80JW+4yOdAiK5+6IS8fiVa7TxdkFDKa0AhmJ1DTHXIlPjGE4n5; To: [email protected] Message-ID: From: DKIM Tester Reply-To: [email protected] Subject: Automated DKIM Testing (angrychimp.net) X-Outgoing: dhaka Date: Fri, 12 Mar 2010 15:24:15 -0800 Content-Type: text/plain; charset=iso-8859-1 Content-Transfer-Encoding: quoted-printable Content-Disposition: inline MIME-Version: 1.0 Return-Path: [email protected] X-OriginalArrivalTime: 12 Mar 2010 23:25:50.0326 (UTC) FILETIME=[5A0ED160:01CAC23B] I can extract the public key from my DNS just fine, and I believe I'm canonicalizing the headers correctly, but I just can't get the signature validated. I don't think I'm preparing my key or computing the signature validation correctly. Is this something that's possible (do I need pear extensions or something?) or is manually validating a DKIM signature in PHP just not feasible?

What encoding should I use?

  • In Protobuf-net how can I pass an array of type object with objects of different types inside, knowi

    - by cloudraven
    I am trying to migrate existing code that uses XmlSerializer to protobuf-net due to the increased performance it offers, however I am having problems with this specific case. I have an object[] that includes parameters that are going to be sent to a remote host (sort of a custom mini rpc facility). I know the set of types from which these parameters can be, but I cannot tell in advance in which order they are going to be sent. I have three constraints. The first is that I am running in Compact Framework, so I need something that works there. Second, as I mentioned performance is a big concern (on the serializing side) so I would rather avoid using a lot of reflection there if possible. And the most important is that I care about the order in which this parameters were sent. Using XmlSerializer it was easy just adding XmlInclude, but for fields there is nothing equivalent as far as I know in Protobuf-net. So, is there a way to do this? Here is a simplified example. [Serializable] [XmlInclude(typeof(MyType1)), XmlInclude(typeof(MyType2)), XmlInclude(typeof(MyType3)) public class Message() { public object[] parameters; public Message(object[] parms) { parameters = parms; } } Message m = new Message(new object[] {MyType1(), 33, "test", new MyType3(), new MyType3()}); MemoryStream ms = new MemoryStream(); XmlSerializer xml = new XmlSerializer(typeof(Message)); xml.Serialize(ms,xml); That will just work with XmlSerializer, but if I try to convert it to protobuf-net I will get a "No default encoding for Object" message. The best I came up with is to use generics and [ProtoInclude] as seen in this example. Since I can have different object types within the array this doesn't quite make it. I added a generic List for each potential type and a property with [ProtoIgnore] with type object[] to add them and get them. I have to use reflection when adding them (to know in which array to put each item) which is not desirable and I still can't preserve the ordering as I just extract all the items on each list one by one and put them into a new object[] array on the property get. I wonder if there is a way to accomplish this?

  • Wiki-fying a text using LPeg

    - by Stigma
    Long story coming up, but I'll try to keep it brief. I have many pure-text paragraphs which I extract from a system and re-output in wiki format so that the copying of said data is not such an arduous task. This all goes really well, except that there are no automatic references being generated for the 'topics' we have pages for, which end up needing to be added by reading through all the text and adding it in manually by changing Topic to [[Topic]]. First requirement: each topic is only to be made clickable once, which is the first occurrence. Otherwise, it would become a really spammy linkfest, which would detract from readability. To avoid issues with topics that start with the same words Second requirement: overlapping topic names should be handled in such a way that the most 'precise' topic gets the link, and in later occurrences, the less precise topics do not get linked, since they're likely not correct. Example: topics = { "Project", "Mary", "Mr. Moore", "Project Omega"} input = "Mary and Mr. Moore work together on Project Omega. Mr. Moore hates both Mary and Project Omega, but Mary simply loves the Project." output = function_to_be_written(input) -- "[[Mary]] and [[Mr. Moore]] work together on [[Project Omega]]. Mr. Moore hates both Mary and Project Omega, but Mary simply loves the [[Project]]." Now, I quickly figured out a simple or complicated string.gsub() could not get me what I need to satisfy the second requirement, as it provides no way to say 'Consider this match as if it did not happen - I want you to backtrack further'. I need the engine to do something akin to: input = "abc def ghi" -- Looping over the input would, in this order, match the following strings: -- 1) abc def ghi -- 2) abc def -- 3) abc -- 4) def ghi -- 5) def -- 6) ghi Once a string matches an actual topic and has not been replaced before by its wikified version, it is replaced. If this topic has been replaced by a wikified version before, don't replace, but simply continue the matching at the end of the topic. (So for a topic "abc def", it would test "ghi" next in both cases.) Thus I arrive at LPeg. I have read up on it, played with it, but it is considerably complex, and while I think I need to use lpeg.Cmt and lpeg.Cs somehow, I am unable to mix the two properly to make what I want to do work. I am refraining from posting my practice attempts as they are of miserable quality and probably more likely to confuse anyone than assist in clarifying my problem. (Why do I want to use a PEG instead of writing a triple-nested loop myself? Because I don't want to, and it is a great excuse to learn PEGs.. except that I am in over my head a bit. Unless it is not possible with LPeg, the first is not an option.)

  • In MySQL, what is the most effective query design for joining large tables with many to many relatio

    - by lighthouse65
    In our application, we collect data on automotive engine performance -- basically source data on engine performance based on the engine type, the vehicle running it and the engine design. Currently, the basis for new row inserts is an engine on-off period; we monitor performance variables based on a change in engine state from active to inactive and vice versa. The related engineState table looks like this: +---------+-----------+---------------+---------------------+---------------------+-----------------+ | vehicle | engine | engine_state | state_start_time | state_end_time | engine_variable | +---------+-----------+---------------+---------------------+---------------------+-----------------+ | 080025 | E01 | active | 2008-01-24 16:19:15 | 2008-01-24 16:24:45 | 720 | | 080028 | E02 | inactive | 2008-01-24 16:19:25 | 2008-01-24 16:22:17 | 304 | +---------+-----------+---------------+---------------------+---------------------+-----------------+ For a specific analysis, we would like to analyze table content based on a row granularity of minutes, rather than the current basis of active / inactive engine state. For this, we are thinking of creating a simple productionMinute table with a row for each minute in the period we are analyzing and joining the productionMinute and engineEvent tables on the date-time columns in each table. So if our period of analysis is from 2009-12-01 to 2010-02-28, we would create a new table with 129,600 rows, one for each minute of each day for that three-month period. The first few rows of the productionMinute table: +---------------------+ | production_minute | +---------------------+ | 2009-12-01 00:00 | | 2009-12-01 00:01 | | 2009-12-01 00:02 | | 2009-12-01 00:03 | +---------------------+ The join between the tables would be engineState AS es LEFT JOIN productionMinute AS pm ON es.state_start_time <= pm.production_minute AND pm.production_minute <= es.event_end_time. This join, however, brings up multiple environmental issues: The engineState table has 5 million rows and the productionMinute table has 130,000 rows When an engineState row spans more than one minute (i.e. the difference between es.state_start_time and es.state_end_time is greater than one minute), as is the case in the example above, there are multiple productionMinute table rows that join to a single engineState table row When there is more than one engine in operation during any given minute, also as per the example above, multiple engineState table rows join to a single productionMinute row In testing our logic and using only a small table extract (one day rather than 3 months, for the productionMinute table) the query takes over an hour to generate. In researching this item in order to improve performance so that it would be feasible to query three months of data, our thoughts were to create a temporary table from the engineEvent one, eliminating any table data that is not critical for the analysis, and joining the temporary table to the productionMinute table. We are also planning on experimenting with different joins -- specifically an inner join -- to see if that would improve performance. What is the best query design for joining tables with the many:many relationship between the join predicates as outlined above? What is the best join type (left / right, inner)?

  • Write binary stream to browser using PHP

    - by Dave Jarvis
    Background Trying to stream a PDF report written using iReport through PHP to the browser. The general problem is: how do you write binary data to the browser using PHP? Working Code The following code does the job, but (for many reasons) it is not as efficient as it should be (the code writes a file then sends the file contents the browser). // Load the MySQL database driver. // java( 'java.lang.Class' )->forName( 'com.mysql.jdbc.Driver' ); // Attempt a database connection. // $conn = java( 'java.sql.DriverManager' )->getConnection( "jdbc:mysql://localhost:3306/climate?user=$user&password=$password" ); // Extract parameters. // $params = new java('java.util.HashMap'); $params->put('DistrictCode', '101'); $params->put('StationCode', '0066'); $params->put('CategoryCode', '010'); // Use the fill manager to produce the report. // $fm = java('net.sf.jasperreports.engine.JasperFillManager'); $pm = $fm->fillReport($report, $params, $conn); header('Cache-Control: no-cache private'); header('Content-Description: File Transfer'); header('Content-Disposition: attachment, filename=climate-report.pdf'); header('Content-Type: application/pdf'); header('Content-Transfer-Encoding: binary'); header('Content-Length: ' . strlen( $result ) ); $path = realpath( "." ) . "/output.pdf"; $em = java('net.sf.jasperreports.engine.JasperExportManager'); $result = $em->exportReportToPdfFile($pm,$path); readfile( $path ); $conn->close(); Non-working Code To remove the slight redundancy (i.e., write directly to the browser), the following code looks like it should work, but it does not: $em = java('net.sf.jasperreports.engine.JasperExportManager'); $result = $em->exportReportToPdf($pm); header('Content-Length: ' . strlen( $result ) ); echo $result; Content is sent to the browser, but the file is corrupt (it begins with the PDF header) and cannot be read by any PDF reader. Question How can I take out the middle step of writing to the file and write directly to the browser so that the PDF is not corrupted? Thank you!

  • Fuzzy Regex, Text Processing, Lexical Analysis?

    - by justinzane
    I'm not quite sure what terminology to search for, so my title is funky... Here is the workflow I've got: Semi-structured documents are scanned to file. The files are OCR'd to text. The text is parsed into Python objects The objects are serialized (to SQL, JSON, whatever) for use. The documents are structures like this: HEADER blah blah, Page ### blah Garbage text... 1. Question Text... continued until now. A. Choice text... adsadsf. B. Another Choice... 2. Another Question... I need to extract the questions and choices. The problem is that, because the text is OCR output, there are occasional strange substitutions like '2' - 'Z' which makes ordinary regular expressions useless. I've tried the Levenshtein module and it helps, but it requires prior knowledge of what edit distance is to be expected. I don't know whether I'm looking to create a parser? a lexer? something else? This has lead me down all kinds of interesting but nonrelevant paths. Guidance would be greatly appreciated. Oh, also, the text is generally from specific technical domains, so general spelling tools are not so helpful. Regarding the structure of the documents, there is no clear visual pattern -- like line breaks or indentation -- with the exception of the fact that "questions" usually begin a line. Crap on the document can cause characters to appear before the actual beginning of the line, which means that something along the lines of r'^[0-9]+' does not reliably work. Though the "questions" always begin with an int, a period and a space; the OCR can substitute other characters or skip characters. This is not so much a problem with Tesseract or Cunieform, rather with the poor quality of the paper documents. # Note: for the project in question, it was decided that having a human prep the OCR'd text was better that spending the time coding a solution. I'd still love good pointers, however.

  • Trying to populate ListView in Android using objects from Parse

    - by mrwienerdog
    I am pretty darned new to android, and VERY new to Parse. I have created a class, StudentInformation, that includes columns for name, address, phone, etc. I would like to create a listview that contains the names of all students added to the class. How do I do this? I have got it to the point that I can Toast out the objectIDs of all of my entries, but can't figure out how to extract and add just the names to the ListView. Here is a snippet of the code: //Set up the listview studentListView = (ListView)findViewById(R.id.listViewStudents); //Create and populate an ArrayList of objects from parse ParseQuery query = new ParseQuery("StudentInformation"); final ArrayList<Object> studentList = new ArrayList<Object>(); query.findInBackground(new FindCallback() { public void done(List<ParseObject> objects, ParseException e) { if (e == null) { Toast.makeText(getApplicationContext(), objects.toString(), Toast.LENGTH_LONG).show(); for(int i = 0;i < objects.size(); i++){ objects.get(i); studentList.add("name".toString()); } } else { Toast.makeText(getApplicationContext(), "Error", Toast.LENGTH_LONG).show(); } } }); //studentList.addAll(Arrays.asList(students)); listAdapter = new ArrayAdapter<Object>(this,android.R.layout.simple_list_item_1,studentList); studentListView.setAdapter(listAdapter); } I have left the toast in where I toatst out the objectIDs in the public void done.... method. Any help would be, as always, greatly appreciated. Should be mentioned (possibly), no errors are thrown, the listview just never gets populated after the toast disappears. Don't know if this will help anyone, but I took a bit from both posts below, and came up with this: //Set up the listview studentList = new ArrayList<String>(); //Create and populate an ArrayList of objects from parse listAdapter = new ArrayAdapter<String>(this,android.R.layout.simple_list_item_1); studentListView = (ListView)findViewById(R.id.listViewStudents); studentListView.setAdapter(listAdapter); final ParseQuery query = new ParseQuery("StudentInformation"); query.findInBackground(new FindCallback() { public void done(List<ParseObject> objects, ParseException e) { if (e == null) { //Toast.makeText(getApplicationContext(), objects.toString(), Toast.LENGTH_LONG).show(); for (int i = 0; i < objects.size(); i++) { Object object = objects.get(i); String name = ((ParseObject) object).getString("name").toString(); listAdapter.add(name); } } else { Toast.makeText(getApplicationContext(), "Error", Toast.LENGTH_LONG).show(); } } });

  • Robust LINQ to XML query for sibling key-value pairs

    - by awshepard
    (First post, please be gentle!) I am just learning about LINQ to XML in all its glory and frailty, trying to hack it to do what I want to do: Given an XML file like this - <list> <!-- random data, keys, values, etc.--> <key>FIRST_WANTED_KEY</key> <value>FIRST_WANTED_VALUE</value> <key>SECOND_WANTED_KEY</key> <value>SECOND_WANTED_VALUE</value> <!-- wanted because it's first --> <key>SECOND_WANTED_KEY</key> <value>UNWANTED_VALUE</value> <!-- not wanted because it's second --> <!-- nonexistent <key>THIRD_WANTED_KEY</key> --> <!-- nonexistent <value>THIRD_WANTED_VALUE</value> --> <!-- more stuff--> </list> I want to extract the values of a set of known "wanted keys" in a robust fashion, i.e. if SECOND_WANTED_KEY appears twice, I only want SECOND_WANTED_VALUE, not UNWANTED_VALUE. Additionally, THIRD_WANTED_KEY may or may not appear, so the query should be able to handle that as well. I can assume that FIRST_WANTED_KEY will appear before other keys, but can't assume anything about the order of the other keys - if a key appears twice, its values aren't important, I only want the first one. An anonymous data type consisting of strings is fine. My attempt has centered around something along these lines: var z = from y in x.Descendants() where y.Value == "FIRST_WANTED_KEY" select new { first_wanted_value = ((XElement)y.NextNode).Value, //... } My question is what should that ... be? I've tried, for instance, (ugly, I know) second_wanted_value = ((XElement)y.ElementsAfterSelf() .Where(w => w.Value=="SECOND_WANTED_KEY") .FirstOrDefault().NextNode).Value which should hopefully allow the key to be anywhere, or non-existent, but that hasn't worked out, since .NextNode on a null XElement doesn't seem to work. I've also tried to add in a .Select(t => { if (t==null) return new XElement("SECOND_WANTED_KEY",""); else return t; }) clause in after the where, but that hasn't worked either. I'm open to suggestions, (constructive) criticism, links, references, or suggestions of phrases to Google for, etc. I've done a fair share of Googling and checking around S.O., so any help would be appreciated. Thanks!

  • Drawing a texture with an alpha channel doesn't work -- draws black

    - by DevDevDev
    I am modifying GLPaint to use a different background, so in this case it is white. Anyway the existing stamp they are using assumes the background is black, so I made a new background with an alpha channel. When I draw on the canvas it is still black, what gives? When I actually draw, I just bind the texture and it works. Something is wrong in this initialization. Here is the photo - (id)initWithCoder:(NSCoder*)coder { CGImageRef brushImage; CGContextRef brushContext; GLubyte *brushData; size_t width, height; if (self = [super initWithCoder:coder]) { CAEAGLLayer *eaglLayer = (CAEAGLLayer *)self.layer; eaglLayer.opaque = YES; // In this application, we want to retain the EAGLDrawable contents after a call to presentRenderbuffer. eaglLayer.drawableProperties = [NSDictionary dictionaryWithObjectsAndKeys: [NSNumber numberWithBool:YES], kEAGLDrawablePropertyRetainedBacking, kEAGLColorFormatRGBA8, kEAGLDrawablePropertyColorFormat, nil]; context = [[EAGLContext alloc] initWithAPI:kEAGLRenderingAPIOpenGLES1]; if (!context || ![EAGLContext setCurrentContext:context]) { [self release]; return nil; } // Create a texture from an image // First create a UIImage object from the data in a image file, and then extract the Core Graphics image brushImage = [UIImage imageNamed:@"test.png"].CGImage; // Get the width and height of the image width = CGImageGetWidth(brushImage); height = CGImageGetHeight(brushImage); // Texture dimensions must be a power of 2.
