2.0 Installation information

For information about installing the IBM Rational Deployment Toolkit for WebLogic Server feature, refer to www3.software.ibm.com/ibmdl/pub/software/rationalsdp/rad/60/install_instruction/WLToolkit601/install.html

2.1 Hardware requirements

Refer to the installation instructions for the hardware requirements for installing this feature.

2.2 Software requirements

For software supported by Rational Application Developer, refer to the product Installation Guide for details.

The following software prerequisites exist for this feature:

• IBM Rational Application Developer for WebSphere^® Software 6.0.1 
• BEA WebLogic Server 8.1 SP3, 7.0 SP5, 6.1 SP7 (not supported on Windows XP). These must be installed locally even if the target deployment server is not local.
• Windows 2000, Windows XP

3.0 Known limitations, problems, and workarounds

This release note includes release-specific information, such as problems and limitations that were not available until after the product documentation was finalized.

3.1 Server configurations

1. Reusing WebLogic domains for server configurations or sharing domains among more than one server configuration is not recommended, as it will cause publishing and deployment problems. 
2. Using the WebLogic administration console to remove applications deployed with IBM Rational Application Developer will cause publishing and deployment problems.
3. The WebLogic Domain Configuration Wizard only runs in GUI mode on some Unix systems. It has been tested using the TWM window manager with the GNOME desktop on Red Hat Linux^TM 7.2. 

3.2 Publishing to server

1. The server synchronization state will still read 'Synchronized' if a change is made to a project that is associated with a server configuration. The state only changes if the server configuration itself needs to be republished. 
2. The server publish preferences should be set to use Publish All or Smart Publish. Prompt user publishing method does not work.
3. Unable to deploy application because of FileNotFoundException META-INF/ejb-jar.xml not found in jar. Actually caused by concurrent access problem when a deploy, redeploy, or undeploy action is interrupted by another action or a shutdown. 
4. Unable to redeploy EAR after adding an EJB while the server is running. 

3.3 Server startup

1. WebLogic Server 6.1 is not supported on Windows XP due to issues with authentication. 
2. WebLogic Server 6.1 stays in "Starting" state and never progresses to "Started" on Windows NT^®. Upgrade to WebLogic Server 6.1 SP4.
3. An UnavailableException may occur when the server is started if a client attempts to access the web container before it is fully initialized. May cause problems for Run on Server which causes a server restart. A subsequent Run on Server should succeed. 
4. The error message 'found no context for "/"' will appear if no web application was deployed and bound to the default context. 
5. WebLogic Server will not start if the PATH system environment variable is too long (greater than 1024 characters). 
6. Restarting a local WebLogic Server 6.1 while it is running does not work. The workaround is to check the debug view to ensure the server process is terminated before restarting the server.
7. An enterprise application project with a different server runtime version than the WebLogic server can incorrectly be configured to the server by "Run on Server". 

3.4 Server editor

1. Cannot undo port number changes if the port number is invalid (must be a positive integer or –1; 0 is not allowed). 
2. You are asked to save changes to the EJB Deployment Descriptor Editor or the Server Editor after adding/removing an enterprise application to a server and publishing the server. 

3.5 EJB to RDB mapping

1. EJB Deployment Descriptor editors and EJB to RDB Mapping editors sometimes open in the dirty state. This indicates that the model loaded in memory has been modified in some way. Save the editor to avoid any potential model synchronization problems.
2. The scenario of generating a top-down map, then using the tables created by the Mapping Editor's generated DDL to do a bottom-up mapping is unsupported. The toolkit will incorrectly fill out the tag in weblogic-cmp-rdbms-jar.xml. 

3.6 EJB management

1. An exception occurs when importing an EAR that contains both a Web project and an EJB project with an EJB.
2. Adding and removing beans from an EJB module may fail to synchronize the WebLogic-specific descriptors if the enterprise application has been recently removed from a server configuration. 
3. An exception occurs when creating a CMP 1.1 bean in an EJB 2.0 project.

3.7 Universal Test Client (UTC)

1. Local home interface lookup in WebLogic Server 8.1 and 7.0 does not work in the Universal Test Client due to the way JNDI is implemented in WebLogic Server. 
2. JNDI navigation via hyperlinks in the JNDI Explorer is not supported due to the difference in WebLogic Server's implementation of JNDI. To use the JNDI Explorer, perform a lookup on the fully-qualified JNDI name.
3. If the server is republished while the Web browser is open to the Universal Test Client, it must be reinitialized by performing a Run on Server or manually setting the JNDI properties. 

3.8 JSP debugging

1. Stepping over JSP lines is limited to JSP scriptlet and JSP declaration code. 
2. Stepping in and out of JSP lines outside of JSP scriptlet and JSP declaration code is not supported.
3. The debugger will not be able to identify the sources for JSPs when debugging if a situation causes the server to change state to "needs republish", such as modifying sources in the deployed application. 

3.9 EJB validation

1. Server projects need to auto-validate in order for the WebLogic Server Configuration Validator to provide useful warning messages when applications are not fully enabled for WLS.
2. EJB inheritance is not supported in WebLogic Server but it passes ejbc validation. 
3. There are always warnings when validating EJB beans. The ejbc command complains that the same class file is location in both ejb-jar file and the ejbModule directory.

3.10 CMR

1. WAS EJB 1.1 relationships: Creating WAS EJB 1.1 relationships in a WebLogic-enabled EJB project will cause resource save problems. 
2. EJB 2.0 relationships: Relation with two identical relationship role names is allowed. 

3.11 Scenario applications

3.12 DDConverter
