• Java errors on Lotus Domino Designer Client 8.5.1

  - by ajcooper

  I have a clean install of Lotus Notes 8.5.1 (now with FP3) and I'm getting the following errors in Designer. This is with a new database with a couple of forms and views. I'm finding this is typical across all databases. Is there something I need to install/configure etc.? I'm not new to Notes, but I'm new to 8.5 Thanks Aidan Description Resource Path Location Type Cannot resolve plug-in: org.eclipse.core.runtime plugin.xml TestAgent.nsf line 9 Plug-in Problem Cannot resolve plug-in: org.eclipse.ui plugin.xml TestAgent.nsf line 8 Plug-in Problem Cannot resolve plug-in: com.ibm.commons plugin.xml TestAgent.nsf line 10 Plug-in Problem Cannot resolve plug-in: com.ibm.commons.vfs plugin.xml TestAgent.nsf line 12 Plug-in Problem Cannot resolve plug-in: com.ibm.commons.xml plugin.xml TestAgent.nsf line 11 Plug-in Problem Cannot resolve plug-in: com.ibm.designer.runtime plugin.xml TestAgent.nsf line 15 Plug-in Problem Cannot resolve plug-in: com.ibm.designer.runtime.directory plugin.xml TestAgent.nsf line 14 Plug-in Problem Cannot resolve plug-in: com.ibm.jscript plugin.xml TestAgent.nsf line 13 Plug-in Problem Cannot resolve plug-in: com.ibm.notes.java.api plugin.xml TestAgent.nsf line 20 Plug-in Problem Cannot resolve plug-in: com.ibm.xsp.core plugin.xml TestAgent.nsf line 16 Plug-in Problem Cannot resolve plug-in: com.ibm.xsp.core plugin.xml TestAgent.nsf line 21 Plug-in Problem Cannot resolve plug-in: com.ibm.xsp.designer plugin.xml TestAgent.nsf line 18 Plug-in Problem Cannot resolve plug-in: com.ibm.xsp.designer plugin.xml TestAgent.nsf line 22 Plug-in Problem Cannot resolve plug-in: com.ibm.xsp.domino plugin.xml TestAgent.nsf line 19 Plug-in Problem Cannot resolve plug-in: com.ibm.xsp.domino plugin.xml TestAgent.nsf line 23 Plug-in Problem Cannot resolve plug-in: com.ibm.xsp.extsn plugin.xml TestAgent.nsf line 17 Plug-in Problem Cannot resolve plug-in: com.ibm.xsp.extsn plugin.xml TestAgent.nsf line 24 Plug-in Problem Cannot resolve plug-in: com.ibm.xsp.rcp plugin.xml TestAgent.nsf line 25 Plug-in Problem

• WCF Certificates without Certificate Store

  - by Kane

  My team is developing a number of WPF plug-ins for a 3rd party thick client application. The WPF plug-ins use WCF to consume web services published by a number of TIBCO services. The thick client application maintains a separate central data store and uses a proprietary API to access the data store. The thick client and WPF plug-ins are due to be deployed onto 10,000 workstations. Our customer wants to keep the certificate used by the thick client in the central data store so that they don't need to worry about re-issuing the certificate (current re-issue cycle takes about 3 months) and also have the opportunity to authorise the use of the certificate. The proposed architecture offers a form of shared secret / authentication between the central data store and the TIBCO services. Whilst I don’t necessarily agree with the proposed architecture our team is not able to change it and must work with what’s been provided. Basically our client wants us to build into our WPF plug-ins a mechanism which retrieves the certificate from the central data store (which will be allowed or denied based on roles in that data store) into memory then use the certificate for creating the SSL connection to the TIBCO services. No use of the local machine's certificate store is allowed and the in memory version is to be discarded at the end of each session. So the question is does anyone know if it is possible to pass an in-memory certificate to a WCF (.NET 3.5) service for SSL transport level encryption? Note: I had asked a similar question (here) but have since deleted it and re-asked it with more information.

• Optimising RSS parsing on App Engine to avoid high CPU warnings

  - by Danny Tuppeny

  I'm pulling some RSS feeds into a datastore in App Engine to serve up to an iPhone app. I use cron to schedule updating the RSS every x minutes. Each task only parses one RSS feed (which has 15-20 items). I frequently get warnings about high CPU usage in the App Engine dashboard, so I'm looking for ways to optimise my code. Currently, I use minidom (since it's already there on App Engine), but I suspect it's not very efficient! Here's the code: dom = minidom.parseString(urlfetch.fetch(url).content) if dom: items = [] for node in dom.getElementsByTagName('item'): item = RssItem( key_name = self.getText(node.getElementsByTagName('guid')[0].childNodes), title = self.getText(node.getElementsByTagName('title')[0].childNodes), description = self.getText(node.getElementsByTagName('description')[0].childNodes), modified = datetime.now(), link = self.getText(node.getElementsByTagName('link')[0].childNodes), categories = [self.getText(category.childNodes) for category in node.getElementsByTagName('category')] ); items.append(item); db.put(items); def getText(self, nodelist): rc = '' for node in nodelist: if node.nodeType == node.TEXT_NODE: rc = rc + node.data return rc There isn't much going on, but the scripts often take 2-6 seconds CPU time, which seems a bit excessive for looping through 20ish items and reading a few attributes. What can I do to make this faster? Is there anything particularly bad in the above code, or should I change to another way of parsing? Are there are any libraries (that work on App Engine) that would be better, or would I be better parsing the RSS myself?

• can't write to physical drive in win 7??

  - by matt

  I wrote a disk utility that allowed you to erase whole physical drives. it uses the windows file api, calling : destFile = CreateFile("\\.\PhysicalDrive1", GENERIC_WRITE, FILE_SHARE_READ | FILE_SHARE_WRITE, NULL, OPEN_EXISTING,createflags, NULL); and then just calling WriteFile, and making sure you write in multiples of sectors, i.e. 512 bytes. this worked fine in the past, on XP, and even on the Win7 RC, all you have to do is make sure you are running it as an administrator. but now I have retail Win7 professional, it doesn't work anymore! the drives still open fine for writing, but calling WriteFile on the successfully opened Drive now fails! does anyone know why this might be? could it have something to do with opening it with shared flags? this is always what I have done before, and its worked. could it be that something is now sharing the drive? blocking the writes? is there some way to properly "unmount" A drive, or atleast the partitions on it so that I would have exclusive access to it? some other tools that used to work don't any more either, but some do, like the WD Diagnostic's erase functionality. and after it has erased the drive, my tool then works on it too! leading me to belive there is some "unmount" process I need to be doing to the drive first, to free up permission to write to it. Any ideas?

• Fluent NHibernate auto mapping: map property from another table's column

  - by queen3

  I'm trying to use S#arp architecture... which includes Fluent NHibernate I'm newbie with (and with NHibernate too, frankly speaking). Auto mapping is used. So I have this: public class UserAction : Entity { public UserAction() { } [DomainSignature] [NotNull, NotEmpty] public virtual string Name { get; set; } [NotNull, NotEmpty] public virtual string TypeName { get; private set; } } public class UserActionMap : IAutoMappingOverride<UserAction> { public void Override(AutoMap<UserAction> mapping) { mapping.WithTable("ProgramComponents", m => m.Map(x => x.TypeName)); } } Now, table UserActions references table ProgramComponents (many to one) and I want property UserAction.TypeName to have value from db field ProgramComponents.TypeName. However, the above code fails with NHibernate.MappingException: Duplicate property mapping of TypeName found in OrderEntry3.Core.UserAction As far as I understand the problem is that TypeName is already auto-mapped... but I haven't found a way to remove the automatic mapping. Actually I think that my WithTable/Map mapping has to replace the automatic TypeName mapping, but seems like it does not. I also tried different mapping (names are different but that's all the same): mapping.WithTable("ProgramComponents", m => m.References<ProgramComponent>( x => x.Selector, "ProductSelectorID" ) and still get the same error. I can overcome this with mapping.HasOne<ProgramComponent>(x => x.Selector); but that's not what I exactly wants to do. And I still wonder why the first two methods do not work. I suspect this is because of WithTable.

• [Microsoft][ODBC Driver Manager] Data source name not found and no default driver specified - works

  - by Matt

  Hello, I am developing a java app (with odbc bridge - forgive me - the only paradox driver I have been able to obtain is the microsoft odbc driver) - which works fine while in eclipse, (and netbeans) - connecting and obtaining data from an ancient paradox 5.x database. So long as it is run from inside my IDE - it compiles and runs flawlessly. When I export it to a runable jar, suddenly [code][Microsoft][ODBC Driver Manager] Data source name not found and no default driver specified[/code] occurs. The jar is being run on the same box as my developing IDE - so I am confused about the cause. It is being run via console from a user account, as per the IDE. My connection string is "jdbc:odbc:Driver={Microsoft Paradox Driver (*.db )};DriverID=538; Fil=Paradox 5.X; DefaultDir=C:\paradox\database\location\" - obtained from connectionstrings.com - and as mentioned before, working fine while run from the IDE. The above seems to 'magically' create its own connection, avoiding the setup of a dsn - I am unsure quite how it does - but it works. The only other thing I can think that might be pertinent is that my PC is a 64bit o/s (windows server 2008). Please help, any suggestions or comments will be greatly appreciated. Thanks, Matt

• VS2008 adding SQL Server Database (SQL Server 2008 Mgmt Studio) not working

  - by Kahn

  I'm trying to practice using the ASP.Net MVC at home, but I ran into an impossible problem. I cannot open a connection to SQL Server 2008, I get this error: "Connections to SQL Server files (*.mdf) require SQL Server Express 2005 to function properly. ..." I've googled around for numerous responses, none of them either working or addressing this issue. I'm running Vista 32bit, my SQL Server 2008 Mgmt Studio is also 32bit, I have SP1 installed both on VS2008 Professional, as well as the SQL Server. I changed the machine.config connectionStrings from ./SQLExpress to my SQL Server 2008 name. Now if I connect manually through web.config, in an asp:datasource or code-behind, everything works fine. But for some reason trying to add a DB Connection directly like this always gets the error. This is pretty fatal, since I can't rightly do much unless I can use LINQ to SQL with my MVC test project, and this is the only way I know how. Worked fine in school and work, but not at home. Installing SQL Server Express 2005, as some have suggested, is not an option. Obviously it HAS to work with SQL Server 2008. Thanks in advance.

• jQuery ui datepicker positioning problem when scrolling down webpage

  - by Remnant

  I have a webpage that uses multiple instances of the jQuery ui datepicker. My webpage will display ~80 records which extends beyond a single screenshot. <% foreach (var record in Model) { %> <div class="recordname"><%=record.name%></div> <%=Html.TextBox("DateTimePicker", null, new { @class = "date-pick" } )%> // <-- additional html here --> <% } %> I have set the defaults of my datepicker as follows: $(".date-pick").each(function() { $(this).datepicker({ dateFormat: 'dd M yy', showOn: 'button', buttonImage: '/Images/datepickericon.png', buttonImageOnly: true }); }); When the page first loads, if I click any datepicker icon that is visible on screen (i.e. without scrolling) then the datepicker appears as expected. However, if I scroll down the page and then click a datepicker icon, the datepicker does not appear in the screen window but is instead rendered right back near the top of the screen. Any ideas how to solve this? I am using: IE7 asp.net mvc jquery.ui.datepicker.js (UI/API/1.8/Datepicker)

• Missing UAC shield overlay on desktop shortcut icon when created by msi created from VS 2008

  - by Alain Hogue

  I created a setup program to deploy my VBNet program using Visual Studio 2008. Inside this setup program I created a shortcut to the "primary output" to be installed on the user desktop. Now, everything is working correctly. The program is installed under "C:\Program Files" and the shortcut is created on the desktop. Also, when I use this shortcut I am prompted by UAC to autorize running this program as administrator. So far, so good... But! My desktop icon does not have the UAC shield overlay even if the program is compiled with the manifest stating that it must run as administrator. Also, if I manually create a new shortcut on the desktop to the same executable after the installation, this new shortcut WILL have the shield overlay! I have tried to reboot and delete the iconCache.db file but it did not work. So my question is: How can I have my desktop shortcut appear WITH the UAC shield overlay when installed initially. Thanks!

• I/O between AIR client using Native process and executable java .jar

  - by aseem behl

  I am using Adobe AIR 2.0 native process API to launch a java executable jar. I/O is handled by writing to the input stream of the java process and reading from the output stream. The application is event based where several events are fired from the server. We catch these events in java code, handle them and write the output to the outputstream using the synchronized static method below. public class ReaderWriter { static Logger logger = Logger.getLogger(ReaderWriter.class); public synchronized static void writeToAir(String output){ try{ byte[] byteArray = output.getBytes(); DataOutputStream dataOutputStream = new DataOutputStream(System.out); dataOutputStream.write(byteArray); dataOutputStream.flush(); } catch (IOException e) { logger.info("Exception while writing the output. " + e); } } } The issue is that some messages are lost between the transfer and not all messages reach the AIR client. If I run the java application from the console I am receiving all the messages. It would be great if somebody could point out what I am missing. Following are some of the listeners used to send the event data to the AIR client. // class used to process Shutdown events from the Session private class SessionShutdownListener implements SessionListener{ public void onEvent(Event e) { Session.Shutdown sd = (Session.Shutdown) e; Session.ShutdownReason sr = sd.getReason(); String eventOutput = "eo;" + "Session Shutdown event ocurred reason=" + sr.strValue() + "\n"; ReaderWriter.writeToAir(eventOutput); } } // class used to process OperationSucceeded events from the Session private class SessionOperationSucceededListener implements SessionListener{ public void onEvent(Event e) { Session.OperationSucceeded os = (Session.OperationSucceeded) e; String eventOutput = "eo;" + "Session OperationSucceeded event ocurred" + "\n"; ReaderWriter.writeToAir(eventOutput); } }

• Banning by IP with php/mysql

  - by incrediman

  I want to be able to ban users by IP. My idea is to keep a list of IP's as rows in an BannedIPs table (the IP column would be an index). To check users' IP's against the table, I will keep a session variable called $_SESSION['IP'] for each session. If on any request, $_SESSION['IP'] doesn't match $_SERVER['REMOTE_ADDR'], I will update $_SESSION['IP'] and check the BannedIPs table to see if the IP is banned. (A flag will also be saved as a session variable specifying whether or not the user is banned) Here are the things I'm wondering: Does that sound like a good strategy with regards to speed and security (would someone be able to get around the IP ban somehow, other than changing IP's)? What's the best way to structure a mysql query that checks to see if a row exists? That is, what's the best way to query the db to see if a row with a certain IP exists (to check if it's banned)? Should I save the IP's as integers or strings? Note that... I estimate there will be between 1,000-10,000 banned IP's stored in the database. $_SERVER['REMOTE_ADDR'] is the IP from which the current request was sent.

• Groovlet + Tomcat: "unable to resolve class" when importing libraries

  - by Rob Hruska

  I'm having some trouble running a groovy servlet (groovlet) in tomcat that imports a library class. When I don't import anything the groovlet works correctly, but if I do import something that I expect to be on the classpath (I can import the same class successfully in a regular servlet), I see the following error: groovy.util.ScriptException: Could not parse scriptName: /MyGroovlet.groovy java.lang.RuntimeException: groovy.util.ScriptException: Could not parse scriptName: /MyGroovlet.groovy at groovy.servlet.GroovyServlet$1.call(GroovyServlet.java:123) ... Caused by: org.codehaus.groovy.control.MultipleCompilationErrorsException: startup failed, /MyGroovlet.groovy: 1: unable to resolve class com.mycompany.mypackage.MyLibraryClass @ line 1, column 1. The jar containing MyLibraryClass is in shared/lib, which is loaded by tomcat by the following in catalina.properties: shared.loader=...,${catalina.base}/shared/lib/*.jar,... My groovlets are mapped as described in the user guide in my application's web.xml: <servlet> <servlet-name>GroovyServlet</servlet-name> <servlet-class>groovy.servlet.GroovyServlet</servlet-class> </servlet> <servlet-mapping> <servlet-name>GroovyServlet</servlet-name> <url-pattern>*.groovy</url-pattern> </servlet-mapping> And here's the code for the groovlet, MyGroovlet.groovy: import com.mycompany.mypackage.MyLibraryClass MyLibraryClass.someStaticMethod() My groovlet is deployed to WEB-INF/groovy/MyGroovlet.groovy, per the GroovyServlet API. When I visit http://localhost:8080/myapplication/MyGroovlet.groovy, the error described previously is written to my application logs. Is there some way that I need to explicitly declare the runtime classpath for GroovyServlet? I've tried moving the library jar to several places, including WEB-INF/lib and moving the actual MyLibraryClass.class file to WEB-INF/classes, but with no luck.

• Can a GeneralPath be modified?

  - by Dov

  java2d is fairly expressive, but requires constructing lots of objects. In contrast, the older API would let you call methods to draw various shapes, but lacks all the new features like transparency, stroke, etc. Java has fairly high costs associated with object creation. For speed, I would like to create a GeneralPath whose structure does not change, but go in and change the x,y points inside. path = new GeneralPath(GeneralPath.WIND_EVEN_ODD, 10); path.moveTo(x,y); path.lineTo(x2, y2); double len = Math.sqrt((x2-x)*(x2-x) + (y2-y)*(y2-y)); double dx = (x-x2) * headLen / len; double dy = (y-y2) * headLen / len; double dx2 = -dy * (headWidth/headLen); double dy2 = dx * (headWidth/headLen); path.lineTo(x2 + dx + dx2, y2 + dy + dy2); path.moveTo(x2 + dx - dx2, y2 + dy - dy2); path.lineTo(x2,y2); This one isn't even that long. Imagine a much longer sequence of commands, and only the ones on the end are changing. I just want to be able to overwrite commands, to have an iterator effectively. Does that exist?

• dynamically horizontal scalable key value store

  - by Zubair

  Hi, Is there a key value store that will give me the following: Allow me to simply add and remove nodes and will redstribute the data automatically Allow me to remove nodes and still have 2 extra data nodes to provide redundancy Allow me to store text or images up to 1GB in size Can store small size data up to 100TB of data Fast (so will allow queries to be performed on top of it) Make all this transparent to the client Works on Ubuntu/FreeBSD or Mac Free or open source I basically want something I can use a "single", and not have to worry about having memcached, a db, and several storage components so yes, I do want a database "silver bullet" you could say. Thanks Zubair Answers so far: MogileFS on top of BackBlaze - As far as I can see this is just a filesystem, and after some research it only seems to be appropriate for large image files Tokyo Tyrant - Needs lightcloud. This doesn't auto scale as you add new nodes. I did look into this and it seems it is very fast for queries which fit onto a single node though Riak - This is one I am looking into myself, but I don't have any results yet Amazon S3 - Is anyone using this as their sole persistance layer in production? From what I have seen it seems to be used for storage of images as complex queries are too expensive @shaman suggested Cassandra - definitely one I am looking into So far it seems that there is no database or key value store that fulfills the criteria I mentioned, not even after offering a bounty of 100 points did the question get answered!

• How do you find a functions virtual call address in assembly?

  - by Daniel

  I've googled around but i'm not sure i am asking the right question or not and i couldn't find much regardless, perhaps a link would be helpful. I made a c++ program that shows a message box, then I opened it up with Ollydbg and went to the part where it calls MessageBoxW. The call address of MessageBoxW changes each time i run the app as windows is updating my Imports table to have the correct address of MessageBoxW. So my question is how do i find the virtual addres of MessageBoxW to my imports table and also how can i use this in ollydbg? Basically I'm trying to make a code cave in assembly to call MessageBoxW again. I got fairly close once by searching the executable with a hex editor and found the position of the call, and I think I found the virtual address. But when i call that virtual address in olly and saved it to the executable, the next time i opened it the call was replaced with a bunch of DB xyz (which looked like the virtual address but why did the call get removed? Sorry if my terminology is off as i'm new to this so i'm not quite sure what to call things.

• How to connect to SQLServer 2k5 using Ruby 1.8.7 over W2k3 with active record 2.3.5

  - by Luke

  Hi all, sorry for the blast. I'm trying to connect to an SQLServer 2k5 using Ruby 1.8.7 over W2k3 with active record 2.3.5. But, when I ran 'rake migrate' it throws the following: rake migrate --trace Hoe.new {...} deprecated. Switch to Hoe.spec. Invoke migrate (first_time) Invoke environment (first_time) Execute environment Execute migrate rake aborted! no such file to load -- odbc (...) C:/Program Files/test/Rakefile:146 (...) So, my Rakefile in the line 146 says: ActiveRecord::Migrator.migrate('db/migrate', ENV["VERSION"] ? ENV["VERSION"].to_i : nil ) The database.yml has been configured in so many ways without success. I've tried setup to mode in odbc, to configure a system dsn, to completely use the activerecord support for sqlserver but no success at all. The same Rakefile works fine over Postgres and Oracle with the proper gems installed off course. But I cann't get this work. Any help will be appreciated. Thanks in advance!

• CQRS - The query side

  - by mattcodes

  A lot of the blogsphere articles related to CQRS (command query repsonsibility) seperation seem to imply that all screens/viewmodels are flat. e.g. Name, Age, Location Of Birth etc.. and thus the suggestion that implementation wise we stick them into fast read source etc.. single table per view mySQL etc.. and pull them out with something like primitive SqlDataReader, kick that nasty nhibernate ORM etc.. However, whilst I agree that domain models dont mapped well to most screens, many of the screens that I work with are more dimensional, and Im sure this is pretty common in LOB apps. So my question is how are people handling screen where by for example it displays a summary of customer details and then a list of their orders with a [more detail] link etc.... I thought about keeping with the straight forward SQL query to the Query Database breaking off the outer join so can build a suitable ViewModel to View but it seems like overkill? Alternatively (this is starting to feel yuck) in CustomerSummaryView table have a text/big (whatever the type is in your DB) column called Orders, and the columns for the Order summary screen grid are seperated by , and rows by |. Even with XML datatype it still feeel dirty. Any thoughts on an optimal practice?

• Mocking with Boost::Test

  - by Billy ONeal

  Hello everyone :) I'm using the Boost::Test library for unit testing, and I've in general been hacking up my own mocking solutions that look something like this: //In header for clients struct RealFindFirstFile { static HANDLE FindFirst(LPCWSTR lpFileName, LPWIN32_FIND_DATAW lpFindFileData) { return FindFirstFile(lpFileName, lpFindFileData); }; }; template <typename FirstFile_T = RealFindFirstFile> class DirectoryIterator { //.. Implementation } //In unit tests (cpp) #define THE_ANSWER_TO_LIFE_THE_UNIVERSE_AND_EVERYTHING 42 struct FakeFindFirstFile { static HANDLE FindFirst(LPCWSTR lpFileName, LPWIN32_FIND_DATAW lpFindFileData) { return THE_ANSWER_TO_LIFE_THE_UNIVERSE_AND_EVERYTHING; }; }; BOOST_AUTO_TEST_CASE( MyTest ) { DirectoryIterator<FakeFindFirstFile> LookMaImMocked; //Test } I've grown frustrated with this because it requires that I implement almost everything as a template, and it is a lot of boilerplate code to achieve what I'm looking for. Is there a good method of mocking up code using Boost::Test over my Ad-hoc method? I've seen several people recommend Google Mock, but it requires a lot of ugly hacks if your functions are not virtual, which I would like to avoid. Oh: One last thing. I don't need assertions that a particular piece of code was called. I simply need to be able to inject data that would normally be returned by Windows API functions.

• Bloated PDF created by TCPDF

  - by Yogi Yang 007

  In a web app developed in PHP we are generating Quotations and Invoices (which are very simple and of single page) using TCPDF lib. The lib is working just great but it seems to generate very large PDF files. For example in our case it is generating PDF files as large as 4 MB (+/- a few KB). How to reduce this bloating of PDF files generated by TCPDF? Here is code snippet that I am using ob_start(); include('quote_view_bag_pdf.php'); //This file is valid HTML file with PHP code to insert data from DB $quote = ob_get_contents(); //Capture the content of 'quote_view_bag_pdf.php' file and store in variable ob_end_clean(); //Code to generate PDF file for this Quote //This line is to fix a few errors in tcpdf $k_path_url=''; require_once('tcpdf/config/lang/eng.php'); require_once('tcpdf/tcpdf.php'); // create new PDF document $pdf = new TCPDF(); // remove default header/footer $pdf->setPrintHeader(false); $pdf->setPrintFooter(false); // add a page $pdf->AddPage(); // print html formated text $pdf->writeHtml($quote, true, 0, true, 0); //Insert Variables contents here. //Build Out File Name $pdf_out_file = "pdf/Quote_".$_POST['quote_id']."_.pdf"; //Close and output PDF document $pdf->Output($pdf_out_file, 'F'); $pdf->Output($pdf_out_file, 'I'); /////////////// enter code here Hope this code fragment will give some idea?

• How to build n-layered web architecture with PHP?

  I have a description and design of a website and I need to redesign it to allow for new requirements. The website's purpose is the offering of government's contracts and bidding opportunities for different businesses.I'm dealing with the 3-tier architecture PHP website comprising of the user-interface tier(client's web browser),business logic layer(Apache web server with PHP engine in it and a couple of applications running within a web server as well) and a database layer(local mysql database). Now,i need to redesign it to su???rt distributed n-tier architecture and specify how I would go about it.After long hours of research i came to this solution: business logic should be separated into presentation and purely business logic tier to allow for n-layer architecture(user-interface,presentation tier,b.logic and data tier).I have decided to use ??? just for the presentation(since the original existing website is in PHP) and use it within apache web server.In the business logic i want to use J2?? implementation technology instead of implementing it in PHP(i.e using Zend app.server and smarty template) cz J2EE can provide much more essential container services which are essential for business logic,its robustness,maintainability and different critical business operations which will be carried out by the g?v?rnment's website.So,particularly,i want to use J??ss app.server with ?J? business objects in it which would provide all the b.logic in java and would interact with the database and so forth.In order to connect PHP on a web server with java on app.server i'm gonna use PHP/Java bridge API (or maybe Quercus or SOAP is better?).Finally,i have my data tier with mysql which will communicate with b.logic via JD??.Payment system application in ???.server is gonna use S??? to talk with credit card company. From your professional point of view,does it sound like a good way of redesigning the original website to allow for n-tier architecture considering the specifics of the website and the criticality of its operations?(payment system is included in it)or u would personally prefer to use PHP business objects for business logic as well instead of J2EE?If you have any wiser recommendation or some alternative,please let me know what is right or wrong in my current solution. H??? to hear your professional advice very s??n (I'm new to the area of web development) Thanks in advance

• cx_Oracle makes subprocess give OSError

  - by Shrikant Sharat

  I am trying to use the cx_Oracle module with python 2.6.6 on ubuntu Maverick, with Oracle 11gR2 Enterprise edition. I am able to connect to my oracle db just fine, but once I do that, the subprocess module does not work anymore. Here is an iPython session that reproduces the problem... In [1]: import subprocess as sp, cx_Oracle as dbh In [2]: sp.call(['whoami']) sharat Out[2]: 0 In [3]: con = dbh.connect('system', 'password') In [4]: con.close() In [5]: sp.call(['whomai']) --------------------------------------------------------------------------- OSError Traceback (most recent call last) /home/sharat/desk/calypso-launcher/<ipython console> in <module>() /usr/lib/python2.6/subprocess.pyc in call(*popenargs, **kwargs) 468 retcode = call(["ls", "-l"]) 469 """ --> 470 return Popen(*popenargs, **kwargs).wait() 471 472 /usr/lib/python2.6/subprocess.pyc in __init__(self, args, bufsize, executable, stdin, stdout, stderr, preexec_fn, close_fds, shell, cwd, env, universal_newlines, startupinfo, creationflags) 621 p2cread, p2cwrite, 622 c2pread, c2pwrite, --> 623 errread, errwrite) 624 625 if mswindows: /usr/lib/python2.6/subprocess.pyc in _execute_child(self, args, executable, preexec_fn, close_fds, cwd, env, universal_newlines, startupinfo, creationflags, shell, p2cread, p2cwrite, c2pread, c2pwrite, errread, errwrite) 1134 1135 if data != "": -> 1136 _eintr_retry_call(os.waitpid, self.pid, 0) 1137 child_exception = pickle.loads(data) 1138 for fd in (p2cwrite, c2pread, errread): /usr/lib/python2.6/subprocess.pyc in _eintr_retry_call(func, *args) 453 while True: 454 try: --> 455 return func(*args) 456 except OSError, e: 457 if e.errno == errno.EINTR: OSError: [Errno 10] No child processes So, the call to sp.call works fine before connecting to oracle, but breaks after that. Even if I have closed the connection to the database. Looking around, I found http://bugs.python.org/issue1731717 as somewhat related to this issue, but I am not dealing with threads here. I don't know if cx_Oracle is. Moreover, the above issue mentions that adding a time.sleep(1) fixes it, but it didn't help me. Any help appreciated. Thanks.

• My Zend Framework 'quoting' mess.

  - by tharkun

  I've got a probably very simple issue to which I can't find a satisfactory (subjectively seen) answer in the Zend Framework manual or elsewhere... There are so many ways how I can hand over my php variables to my sql queries that I lost the overview and probably I lack some understanding about quoting in general. Prepared Statements $sql = "SELECT this, that FROM table WHERE id = ? AND restriction = ?"; $stmt = $this->_db->query($sql, array($myId, $myValue)); $result = $stmt->fetchAll(); I understand that with this solution I don't need to quote anything because the db handles this for me. Querying Zend_Db_Table and _Row objects over the API $users = new Users(); a) $users->fetchRow('userID = ' . $userID); b) $users->fetchRow('userID = ' . $users->getAdapter()->quote($userID, 'INTEGER')); c) $users->fetchRow('userID = ?', $userID); d) $users->fetchRow('userID = ?', $users->getAdapter()->quote($userID, 'INTEGER')); Questions I understand that a) is not ok because it's not quoted at all. But what about the other versions, what's the best? Is c) being treated like a statement and automatically quoted or do I need to use d) when I use the ? identifier?

• Software Update Notifications

  - by devio

  I am considering implementing some sort of Software Update Notification for one of the web applications I am developing. There are several questions I came across: Should the update check be executed on the client or on the server? Client-side means, the software retrieves the most current version information, performs its checks, and displays the update information. Server-side check means the software sends its version info to the server, which in turn does the calculations and returns information to the client. My guess is that server-side implementation may turn out to be more flexible and more powerful than client-side, as I can add functionality to the server easily, as long as the client understands it. Where should the update info be displayed? Is it ok to display on the login screen? Should only admins see it? (this is a web app with a database, so updating requires manipulation of db and web, which is only done by admins). What about a little beeping flashing icon which increases in size as the version gets more obsolete every day ;) ? Privacy issues Not everybody likes to have their app usage stats broadcast over the internet. TheOnion question: What do you think?

• Draw multiple circles in Google Maps

  - by snorpey

  Hi. I want to draw multiple circles on a map, using the Google Maps API anj jQuery. The following code works as long as the line with drawMapCircle() is commented out (The markers are positioned correctly). What's wrong with my code? $.getJSON( "ajax/show.php", function(data) { $.each(data.points, function(i, point) { map.addOverlay(new GMarker(new GLatLng(point.lat, point.lng))); drawMapCircle(point.lat, point.lng, 0.01, '#0066ff', 2, 0.8, '#0cf', 0.1); }); } ); function drawMapCircle(lat, lng, radius, strokeColor, strokeWidth, strokeOpacity, fillColor, fillOpacity) { var d2r = Math.PI / 180; var r2d = 180 / Math.PI; var Clat = radius * 0.014483; // statute miles into degrees latitude conversion var Clng = Clat/Math.cos(lat * d2r); var Cpoints = []; for (var i = 0; i < 33; i++) { var theta = Math.PI * (i / 16); Cy = lat + (Clat * Math.sin(theta)); Cx = lng + (Clng * Math.cos(theta)); var P = new GLatLng(Cy, Cx); Cpoints.push(P); } var polygon = new GPolygon(Cpoints, strokeColor, strokeWidth, strokeOpacity, fillColor, fillOpacity); map.addOverlay(polygon); }
