This topic describes how to set up and use a WebLogic Server with the Workshop family of products. The topics discussed here are:
To define a server:
Click Next to continue.
For the Select Project to Debug field, use the pull-down
to specify which project will be debugged.
Because
of the possibility of name space collisions, when debugging JSP's,
only one project at a time can be debugged on the server. If you
wish to debug JSP's in another project, you must first change the Select
Project to Debug field. For details on switching projects when
debugging JSP's
see Special Considerations When Debugging
JSPs.
To update the definition for a server:
From Server Overview you can view and set deployment and runtime properties.
Note the Run module directly from the workspace option. This is a WTP feature that allows you to run your application in "exploded" mode where the application runs directly from your workspace. If you wish your application compiled into a WAR file and deployed, you must uncheck this option.
Click here for information on manual deployment.
Workshop supports hot deployment of JSPs and other artifacts like Struts actions.
If you update a JSP, changes are automatically published to the server and you can simply click the Refresh button to see them running live on the server. Other changes are automatically redeployed and the application is restarted as necessary.
To deploy an application manually requires that you create an alternate configuration. For information on how to create an alternate configuration, consult your server documentation.
To deploy the alternate configuration:
Manual deployment is only allowed when the Run module directly from the workspace option is selected.
For WebLogic Server 8.1, you will see this screen that allows you to specify a custom configuration XML file OR to use the existing config.xml without updating.
For WebLogic Server 9.0/9.1, you will see this screen that allows you to use the existing config.xml without updating. For WebLogic Server 9.0/9.1, you cannot specify the name of a custom configuration file. When you click on Manual deployment with existing configuration, the field specifying the config.xml file name is read-only and the Select button is disabled.
To debug on a remote server (or on a local server which is started and managed outside of the IDE), you must configure the server for remote debugging, deploy the application manually and then define the remote server's address.
Configuring the server for remote debugging is a feature of the server. This information is provided for your convenience. For definitive documentation, consult your server documentation.
Workshop uses standard JPDA and self-generated line maps. The JSR-45 debug information has to be disabled. The class debug information has to be enabled by placing the following attributes in the application weblogic.xml file:
<?xml version="1.0" encoding="UTF-8"?> <!DOCTYPE weblogic-web-app PUBLIC "-//BEA Systems, Inc.//DTD Web Application 8.1//EN" "http://www.bea.com/servers/wls810/dtd/weblogic810-web-jar.dtd" > <weblogic-web-app> <jsp-descriptor> <jsp-param> <param-name>compileFlags</param-name> <param-value>-g</param-value> </jsp-param> <jsp-param> <param-name>keepgenerated</param-name> <param-value>true</param-value> </jsp-param> </jsp-descriptor> </weblogic-web-app>
Add the following line to the script file used to start Weblogic Server, e.g. startWeblogic.cmd
set JAVA_OPTIONS=-Xdebug -Xnoagent -Xrunjdwp:transport=dt_socket,address=8453,server=y,suspend=n
The Weblogic Server console should display the message:
Listening for transport dt_socket at address: 8453
Workshop uses standard JPDA and self-generated line maps. The class debug information has to be enabled by placing the following attributes in the application weblogic.xml file:
<?xml version="1.0" encoding="UTF-8"?> <weblogic-web-app xmlns="http://www.bea.com/ns/weblogic/90"> <jsp-descriptor> <keepgenerated>true</keepgenerated> <working-dir>C:\MyApp\jsp-servlet\struts-example_1_1\work</working-dir> <backward-compatible>true</backward-compatible> <debug>true</debug> </jsp-descriptor> <context-root>/</context-root> </weblogic-web-app>
Before attempting to debug an application on a remote server, you must:
When remote debugging an application on a physically separate machine, the debugger will hit JSP breakpoints but the IDE will not show the correct source line in JSP, becasue Workshop is trying to locate the JSP servlet source for line mapping but the files are not available to the IDE.
To enable source debugging of servlets on a separate server, map the following directory (on the remote server) to a local directory, and use the Source Lookup Path dialog, or the Source tab in the Launch Configuration dialog (the Run > Run command), to add the mapped directory to Source Lookup Path.
The JSP servlet src output folder is specified in \WEB-INF\weblogic.xml in the web application, this needs to be configured when setting up remote Weblogic Server for debugging:
<jsp-descriptor> <keepgenerated>true</keepgenerated> <working-dir>C:\MyApp\jsp-servlet\struts-example_1_1\work</working-dir> <backward-compatible>true</backward-compatible> <debug>true</debug> </jsp-descriptor>
$WLS_DOMAIN\server\.wlnotdelete\extract e.g.: C:\bea\user_projects\domains\mydomain\myserver\.wlnotdelete\extract\myserver___wstudio_autoconfig_deployment___struts-example_1_1_dbg
To define a remote server:
Change the Connection Type to Standard (Socket Attach) and specify the Host and Port.
Note that when debugging an application on a remote server, you must not disable the Run module directly from the workspace option when you update server settings.
If you try to run a Kodo JPA application on WebLogic Server (9.1 or 9.2) and you get the error:
kodo.persistence.PersistenceException: No product license key was found...
you must merge the Kodo license.bea content into the WebLogic server license.bea file. To do this,
Workshop requires the final release JPA JAR files. WebLogic Server 9.1 ships with an older version of the JARs. This situation does not arise with WebLogic Server 9.2.
If you receive a No Such Method exception error when you run a JPA applcation (e.g., Kodo or Hiberate) on a version 9.1 copy of WebLogic Server, you can use the following workaround to make your application work correctly.
The workaround to fix this error is:
Step 1: Insert the JPA JARs at the beginning of the server's CLASSPATH
For Hibernate-based applications:
set HIB_JARS=C:\<Project>\WEB-INF\lib\ejb3-persistence.jar;
set CLASSPATH=%HIB_JARS%;%CLASSPATH%
For Kodo-based applications: http://download.oracle.com/docs/cd/E13189_01/kodo/docs40/full/html/ref_guide_deploy.html#ref_gu
set KODO_JARS=D:\<Project>\WEB-INF\lib\kodo.jar;D:\<Project>\WEB-INF\lib\jpa.jar
set CLASSPATH=%KODO_JARS%;%CLASSPATH%
Step 2: Use WAR deployment for testing. (Uncheck the Run module directly from workspace option on the Server Overview.) In this mode, the IDE uses startWebLogic.cmd to start the server, thereby locating the correct JPA libraries.
