Weblogic 10.3 - changing jndi-name with deployment plan fails

Question

I was trying to alter the global jndi name of a stateless ejb by using a deployment plan, but can't get it to work.
- to be able to replace it later on with a deployment plan, I specify a jndi-name in weblogic-ejb-jar.xml (so I do not use the @mappedName)
e.g.
<?xml version="1.0" encoding="UTF-8"?>
<weblogic-ejb-jar xmlns="http://www.bea.com/ns/weblogic/10.0" xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance" xsi:schemaLocation="http://www.bea.com/ns/weblogic/10.0 http://www.bea.com/ns/weblogic/10.0/weblogic-ejb-jar.xsd">
     <weblogic-enterprise-bean>
          <ejb-name>ExampleService</ejb-name>
          <enable-call-by-reference>true</enable-call-by-reference>
          <stateless-session-descriptor>
               <business-interface-jndi-name-map>
                    <business-remote>com.example.ExampleServiceRemote</business-remote>
                    <jndi-name>com.example.ExampleService#com.example.ExampleServiceRemote</jndi-name>
               </business-interface-jndi-name-map>
          </stateless-session-descriptor>
     </weblogic-enterprise-bean>
</weblogic-ejb-jar>
- during deployment I specify a deploymentPlan with following content:
<variable-definition>
<variable>
<name>ejb_jndiname_ExampleService</name>
<value>ExampleService</value>
</variable>
</variable-definition>
<module-override>
<module-name>ExampleService.jar</module-name>
<module-type>ejb</module-type>
<module-descriptor external="true">
<root-element>weblogic-ejb-jar</root-element>
<uri>meta-inf/weblogic-ejb-jar.xml</uri>
<variable-assignment>
<name>ejb_jndiname_ExampleService</name>
<xpath>/weblogic-ejb-jar/weblogic-enterprise-bean/\[ejb-name="ExampleService"\]/stateless-session-descriptor/business-interface-jndi-name-map/\[business-remote="com.example.ExampleServiceRemote"\]/jndi-name</xpath>
<operation>replace</operation>
</variable-assignment>
</module-descriptor>
</module-override>
- after deployment, the original jndi-name ("com.example.ExampleService#com.example.ExampleServiceRemote") is active in the jndi tree instead of "ExampleService"
p.s. When I specified the jndi-name in weblogic-ejb.jar.xml as
     <weblogic-enterprise-bean>
          <ejb-name>ExampleService</ejb-name>
          <enable-call-by-reference>true</enable-call-by-reference>
          <jndi-name>com.example.ExampleService#com.example.ExampleServiceRemote</jndi-name>
     </weblogic-enterprise-bean>
and the replace in the deployment plan as
<variable-assignment>
<name>ejb_jndiname_SecurityService</name>
<xpath>/weblogic-ejb-jar/weblogic-enterprise-bean/\[ejb-name="ExampleService"\]/jndi-name</xpath>
<operation>replace</operation>
</variable-assignment>
the replacement does work (checked by verifying the jndi-name within the deployed ear using the console), but the problem then is that the jndi-name does not appear in the jndi tree (that's why I tried the <business-interface-jndi-name-map>)
Any ideas?
Kind regards,
Ben

Answer 1

After a Service Request and some trial and error, I got it to work after adding the following part in each 'jar module override' section of the deployment plan:
<module-descriptor external="false">
<root-element>ejb-jar</root-element>
<uri>META-INF/ejb-jar.xml</uri>
</module-descriptor>
Apparantly this is needed even though there is no ejb-jar.xml in the jar.
So the deployment plan has to be something like:
<variable-definition>
<variable>
<name>ejb_jndiname_ExampleService</name>
<value>ExampleService</value>
</variable>
</variable-definition>
<module-override>
<module-name>ExampleService.jar</module-name>
<module-type>ejb</module-type>
<module-descriptor external="false">
<root-element>weblogic-ejb-jar</root-element>
<uri>meta-inf/weblogic-ejb-jar.xml</uri>
<variable-assignment>
<name>ejb_jndiname_ExampleService</name>
<xpath>/weblogic-ejb-jar/weblogic-enterprise-bean/[ejb-name="ExampleService"]/stateless-session-descriptor/business-interface-jndi-name-map/[business-remote="com.example.ExampleServiceRemote"]/jndi-name</xpath>
<operation>replace</operation>
</variable-assignment>
</module-descriptor>
<module-descriptor external="false">
<root-element>ejb-jar</root-element>
<uri>META-INF/ejb-jar.xml</uri>
</module-descriptor>
</module-override>
...
