So I made some changes to my WAR file: Added weblogic.jar to my WAR and these properties to persistence.xml <property name="jndi.url" value="t3://localhost:7001"/> | <property name="jndi.class" value="weblogic.jndi.WLInitialContextFactory"/> | Changed the datasource in the Admin Console to the name myWebAppDS and made the change in persistence.xml to the following: <jta-data-source>myWebAppDS</jta-data-source> | Sadly, I am getting the same error. I will keep looking into WebLogic and how it handles JNDI. Thanks for your help and any more insight you may have.
