  • All-around programming language for use on desktop and mobile devices

    - by mdm414 ZX
    Given that I am a PHP programmer and open-source is a must, what would be the best and practical programming language to use for all of the following: A desktop/cross-platform application. I've read that with HTML5, creating offline apps are possible? A web application. Android and iPhone/iPad apps. I am leaning towards using Python but I am not sure if it is possible to use it alone for all of them. There are other languages that I am also looking at like Ruby, Scala and Java. Kindly share your thoughts and experiences on this one. Thanks :-)

  • Complete deployment to AWS

    - by Ionut
    I'm trying to deploy a Java Application to AWS free tier. I need the following: RDS provider. Using MySQL client S3 service. This is required for the Lucene Index and image uploading SES service. I need to be able to send emails to new registered users. Namecheap is my domain provider. EC2 instance Elastic Beanstalk instance. I managed to create an EC2 instance, upload the WAR file and link it to the Namecheap domain. However I find it difficult to link the other instances to the current application. I find the documentation a little messy and I can't find the right way to do this. Can you provide a simple walk through to deployment for this use case? Thanks!

  • Gettings Terms asscoiated to a Specific list item

    - by Gino Abraham
    I had a fancy requirement where i had to get all tags associated to a document set in a document library. The normal tag could webpart was not working when i add it to the document set home page, so planned a custom webpart. Was checking in net to find a straight forward way to achieve this, but was not lucky enough to get something. Since i didnt get any samples in net, i looked into Microsoft.Sharerpoint.Portal.Webcontrols and found a solution.The socialdataframemanager control in 14Hive/Template/layouts/SocialDataFrame.aspx directed me to the solution. You can get the dll from ISAPI folder. Following Code snippet can get all Terms associated to the List Item given that you have list name and id for the list item. using System; using System.Collections.Generic; using System.Linq; using System.Text; using Microsoft.SharePoint; using Microsoft.Office.Server.SocialData; namespace TagChecker { class Program { static void Main(string[] args) { // Your site url string siteUrl = http://contoso; // List Name string listName = "DocumentLibrary1"; // List Item Id for which you want to get all terms int listItemId = 35; using (SPSite site = new SPSite(siteUrl)) { using(SPWeb web = site.OpenWeb()) { SPListItem listItem = web.Lists[listName].GetItemById(listItemId); string url = string.Empty; // Based on the list type the url would be formed. Code Sniffed from Micosoft dlls :) if (listItem.ParentList.BaseType == SPBaseType.DocumentLibrary) { url = listItem.Web.Url.TrimEnd(new char[] { '/' }) + "/" + listItem.Url.TrimStart(new char[] { '/' }); } else if (SPFileSystemObjectType.Folder == listItem.FileSystemObjectType) { url = listItem.Web.Url.TrimEnd(new char[] { '/' }) + "/" + listItem.Folder.Url.TrimStart(new char[] { '/' }); } else { url = listItem.Web.Url.TrimEnd(new char[] { '/' }) + "/" + listItem.ParentList.Forms[PAGETYPE.PAGE_DISPLAYFORM].Url.TrimStart(new char[] { '/' }) + "?ID=" + listItem.ID.ToString(); } SPServiceContext serviceContext = SPServiceContext.GetContext(site); Uri uri = new Uri(url); SocialTagManager mgr = new SocialTagManager(serviceContext); SocialTerm[] terms = mgr.GetTerms(uri); foreach (SocialTerm term in terms) { Console.WriteLine(term.Term.Labels[0].Value ); } } } Console.Read(); } } } Reference dlls added are Microsoft.Sharepoint , Microsoft.Sharepoint.Taxonomy, Microsoft.office.server, Microsoft.Office.Server.UserProfiles from ISAPI folder. This logic can be used to make a custom tag cloud webpart by taking code from OOB tag cloud, so taht you can have you webpart anywhere in the site and still get Tags added to a specifc libdary/List. Hope this helps some one.

  • Data Source Security Part 3

    - by Steve Felts
    In part one, I introduced the security features and talked about the default behavior.  In part two, I defined the two major approaches to security credentials: directly using database credentials and mapping WLS user credentials to database credentials.  Now it's time to get down to a couple of the security options (each of which can use database credentials or WLS credentials). Set Client Identifier on Connection When "Set Client Identifier" is enabled on the data source, a client property is associated with the connection.  The underlying SQL user remains unchanged for the life of the connection but the client value can change.  This information can be used for accounting, auditing, or debugging.  The client property is based on either the WebLogic user mapped to a database user using the credential map Normal 0 false false false EN-US X-NONE X-NONE MicrosoftInternetExplorer4 /* 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:0in; mso-para-margin-bottom:.0001pt; 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;} or is the database user parameter directly from the getConnection() method, based on the “use database credentials” setting described earlier. To enable this feature, select “Set Client ID On Connection” in the Console.  See "Enable Set Client ID On Connection for a JDBC data source" http://docs.oracle.com/cd/E24329_01/apirefs.1211/e24401/taskhelp/jdbc/jdbc_datasources/EnableCredentialMapping.html in Oracle WebLogic Server Administration Console Help. The Set Client Identifier feature is only available for use with the Oracle thin driver and the IBM DB2 driver, based on the following interfaces. For pre-Oracle 12c, oracle.jdbc.OracleConnection.setClientIdentifier(client) is used.  See http://docs.oracle.com/cd/B28359_01/network.111/b28531/authentication.htm#i1009003 for more information about how to use this for auditing and debugging.   You can get the value using getClientIdentifier()  from the driver.  To get back the value from the database as part of a SQL query, use a statement like the following. “select sys_context('USERENV','CLIENT_IDENTIFIER') from DUAL”. Starting in Oracle 12c, java.sql.Connection.setClientInfo(“OCSID.CLIENTID", client) is used.  This is a JDBC standard API, although the property values are proprietary.  A problem with setClientIdentifier usage is that there are pieces of the Oracle technology stack that set and depend on this value.  If application code also sets this value, it can cause problems. This has been addressed with setClientInfo by making use of this method a privileged operation. A well-managed container can restrict the Java security policy grants to specific namespaces and code bases, and protect the container from out-of-control user code. When running with the Java security manager, permission must be granted in the Java security policy file for permission "oracle.jdbc.OracleSQLPermission" "clientInfo.OCSID.CLIENTID"; Using the name “OCSID.CLIENTID" allows for upward compatible use of “select sys_context('USERENV','CLIENT_IDENTIFIER') from DUAL” or use the JDBC standard API java.sql.getClientInfo(“OCSID.CLIENTID") to retrieve the value. This value in the Oracle USERENV context can be used to drive the Oracle Virtual Private Database (VPD) feature to create security policies to control database access at the row and column level. Essentially, Oracle Virtual Private Database adds a dynamic WHERE clause to a SQL statement that is issued against the table, view, or synonym to which an Oracle Virtual Private Database security policy was applied.  See Using Oracle Virtual Private Database to Control Data Access http://docs.oracle.com/cd/B28359_01/network.111/b28531/vpd.htm for more information about VPD.  Using this data source feature means that no programming is needed on the WLS side to set this context; it is set and cleared by the WLS data source code. For the IBM DB2 driver, com.ibm.db2.jcc.DB2Connection.setDB2ClientUser(client) is used for older releases (prior to version 9.5).  This specifies the current client user name for the connection. Note that the current client user name can change during a connection (unlike the user).  This value is also available in the CURRENT CLIENT_USERID special register.  You can select it using a statement like “select CURRENT CLIENT_USERID from SYSIBM.SYSTABLES”. When running the IBM DB2 driver with JDBC 4.0 (starting with version 9.5), java.sql.Connection.setClientInfo(“ClientUser”, client) is used.  You can retrieve the value using java.sql.Connection.getClientInfo(“ClientUser”) instead of the DB2 proprietary API (even if set setDB2ClientUser()).  Oracle Proxy Session Oracle proxy authentication allows one JDBC connection to act as a proxy for multiple (serial) light-weight user connections to an Oracle database with the thin driver.  You can configure a WebLogic data source to allow a client to connect to a database through an application server as a proxy user. The client authenticates with the application server and the application server authenticates with the Oracle database. This allows the client's user name to be maintained on the connection with the database. Use the following steps to configure proxy authentication on a connection to an Oracle database. 1. If you have not yet done so, create the necessary database users. 2. On the Oracle database, provide CONNECT THROUGH privileges. For example: SQL> ALTER USER connectionuser GRANT CONNECT THROUGH dbuser; where “connectionuser” is the name of the application user to be authenticated and “dbuser” is an Oracle database user. 3. Create a generic or GridLink data source and set the user to the value of dbuser. 4a. To use WLS credentials, create an entry in the credential map that maps the value of wlsuser to the value of dbuser, as described earlier.   4b. To use database credentials, enable “Use Database Credentials”, as described earlier. 5. Enable Oracle Proxy Authentication, see "Configure Oracle parameters" in Oracle WebLogic Server Administration Console Help. 6. Log on to a WebLogic Server instance using the value of wlsuser or dbuser. 6. Get a connection using getConnection(username, password).  The credentials are based on either the WebLogic user that is mapped to a database user or the database user directly, based on the “use database credentials” setting.  You can see the current user and proxy user by executing: “select user, sys_context('USERENV','PROXY_USER') from DUAL". Note: getConnection fails if “Use Database Credentials” is not enabled and the value of the user/password is not valid for a WebLogic Server user.  Conversely, it fails if “Use Database Credentials” is enabled and the value of the user/password is not valid for a database user. A proxy session is opened on the connection based on the user each time a connection request is made on the pool. The proxy session is closed when the connection is returned to the pool.  Opening or closing a proxy session has the following impact on JDBC objects. - Closes any existing statements (including result sets) from the original connection. - Clears the WebLogic Server statement cache. - Clears the client identifier, if set. -The WebLogic Server test statement for a connection is recreated for every proxy session. These behaviors may impact applications that share a connection across instances and expect some state to be associated with the connection. Oracle proxy session is also implicitly enabled when use-database-credentials is enabled and getConnection(user, password) is called,starting in WLS Release 10.3.6.  Remember that this only works when using the Oracle thin driver. To summarize, the definition of oracle-proxy-session is as follows. - If proxy authentication is enabled and identity based pooling is also enabled, it is an error. - If a user is specified on getConnection() and identity-based-connection-pooling-enabled is false, then oracle-proxy-session is treated as true implicitly (it can also be explicitly true). - If a user is specified on getConnection() and identity-based-connection-pooling-enabled is true, then oracle-proxy-session is treated as false.

  • Enable Configurator for Return Orders

    - by ChristineS-Oracle
    With release 12.2.4 for non-referenced RMAs, Order Management will allow you to configure the model from Sales Order / Quick Sales Order windows. This is only allowable when profile  OM: Enable Configuration UI for RMA is set to Yes.  All selected options must be returnable, as well as all included items. Order Management explodes included items and creates options and option classes in a way similar to outbound orders. The application creates all selected components with same line number but different option/component number.  Additionally, the application does not allow re-configuration and/or deletion of any line if any line in the same configuration is received, fulfilled, closed, cancelled, or split. For additional information refer to the Oracle Order Management Release Notes for Release 12.2.4 (Doc ID 1906521.1).

  • Failed to start up after upgrading software in ubuntu 10.10

    - by Landy
    I asked this question in SuperUser one hour ago, then I know this community so I moved the question here... I've been running Ubuntu 10.10 in a physical x86-64 machine. Today Update Manager reminded me that there are some updates to install and I confirmed the action. I should had read the update list but I didn't. I can only remember there is an update about cups. After the upgrading, Update Manager requires a restart and I confirmed too. But after the restart, the computer can't start up. There are errors in the console. Begin: Running /scripts/init-premount ... done. Begin: Mounting root file system ... Begin: Running /scripts/local-top ... done. [xxx]usb 1-8: new high speed USB device using ehci_hcd and address 3 [xxx]usb 2-1: new full speed USB device using ohci_hcd and address 2 [xxx]hub 2-1:1.0: USB hub found [xxx]hub 2-1:1.0: 4 ports detected [xxx]usb 2-1.1: new low speed USB device using ohci_hcd and address 3 Gave up waiting for root device.

(initramfs)[cursor is here] At the moment, I can't input anything in the console. The keyboard doesn't work at all. What's wrong? How can I check boot args or "root=" as suggested? How can I fix this issue? Thanks. =============== PS1: the /dev/sda1 is type ext4 (rw,nosuid,nodev) PS2: the /dev/sda1 can be mounted and accessed successfully under SUSE 11 SP1 x64. PS3: From this link, I think the keyboard doesn't work because the USB driver is not loaded at that time.

  • Can't load any applications

    - by oshirowanen
    After installing Eclipse, I wanted to try to enable the global unity menu for Eclipse. Following a guide on the web, I was to make a change to: sudo nano /usr/lib/gtk-2.0/2.10.0/menuproxies/libappmenu.so by changing Eclipse to Xclipse. After making that change, and then running sudo ldconfig. and even restarting, I can no longer open any application. I just see the application appear on the screen for a split second and then it disappears. So far I have noticed that I can no longer load Eclipse and Chrome. Anyone know how to fix this? I have tried changing Xclipse back to Eclipse and running the command sudo ldconfig, but it makes no difference.
