Changing weblogic-application.xml

Question

I deploy an EAR file which contains <prefer-application-packages> at weblogic-application.xml. Then, I deploy other applications. According to CAT, I need to modify weblogic.xml. Can I add new contents to that file without redeployment?

Answer 1

Step1). Deploy your Application as it is at present on the Server. Suppose your Web Application name is “SessionTimeoutWebApp” (I am assuming it as a Exploded WAR file you can work with Archived WAR file as well in the same way)
Step2). Anywhere in your file system Just paste the following “plan.xml” file: (Suppose Location is “F:\SessionTimeout_PlanDemo” )
step3:
<?xml version='1.0' encoding='UTF-8'?>
02     <deployment-plan xmlns="http://www.bea.com/ns/weblogic/90" xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance" xsi:schemaLocation="http://www.bea.com/ns/weblogic/90 http://www.bea.com/ns/weblogic/90/weblogic-deployment-plan.xsd" global-variables="false">
03     
04     <application-name>SessionTimeoutWebApp</application-name> <!-- You need to change this Line and Put your Web Application Name -->
05     <variable-definition>
06     <variable>
07     <name>NewSessionValue</name>
08     <value>100000</value>
09     </variable>
10     </variable-definition>
11     
12     <module-override>
13     <module-name>SessionTimeoutWebApp</module-name> <!-- You need to change this Line and Put your Web Application Name -->
14     <module-type>war</module-type>
15     <module-descriptor external="true">
16     <root-element>web-app</root-element>
17     <uri>WEB-INF/web.xml</uri>
18     <variable-assignment>
19     <name>NewSessionValue</name>
20     <xpath>/web-app/session-config/session-timeout</xpath>
21     </variable-assignment>
22     </module-descriptor>
23     </module-override>
24     <config-root>F:\SessionTimeout_PlanDemo</config-root> <!-- You need to change this Line and Put the location of plan.xml file wherever u have pasted it -->
25     </deployment-plan>
Step4). Login to AdminConsole and goto deployments page—-> the select your Application (After Pressing Lock & Edit Button) –> update (click this button)—> browse your “plan.xml” file location and then finish.
Once the changes will be activated ….Next time your will see that your <session-timeout> value is changed from the AdminConsole or through any other technique like JMX or WLST.
