I'm trying to deploy an ear file twice on **Weblogic 12.2.1.3.0**. The applications are the same expect for context-root.

They have:

1. Same JPA models
2. Same persistance.xml (with same peristance-unit-name)
3. When I deploy "the second" ear and try to access to db from the first one I receive a

Code: [Select all] [Show/ hide]

> java.lang.ClassCastException: com.myApplication.models.entityOne
> cannot be cast to com.myApplication.models.entityOne

It seem that the first ear use its own models but the EntityManager of second one ear.

Structure of my ear file is something like that:

Code: [Select all] [Show/ hide]

/
      - lib
        - jar-with-my-models.jar
        - jar-with-persistance.jar

Persistence.xml is defined as following:

Code: [Select all] [Show/ hide]

<persistence-unit name="my-persistance-unit" transaction-type="JTA">
          <jar-file>jar-with-my-models.jar</jar-file>
     </persistence-unit>

Weblogic.xml is definied as following:

Code: [Select all] [Show/ hide]

<weblogic-web-app
    	xmlns="">
    	<context-root>/console</context-root>
    	<container-descriptor>
    		<show-archived-real-path-enabled>true</show-archived-real-path-enabled>
    		<prefer-web-inf-classes>false</prefer-web-inf-classes>
    		<prefer-application-packages>
    			<package-name>antlr.*</package-name>
    		</prefer-application-packages>
    	</container-descriptor>
    
    	<session-descriptor>
    		<persistent-store-type>memory</persistent-store-type>
    		<sharing-enabled>true</sharing-enabled>
    	</session-descriptor>
    </weblogic-web-app>

I'm deploy twice my ear file because I want to replicate an issue that I received during paralell deploy in weblogic
