I built the Seam JPA example for WebLogic using the build script provided, and I tried deploying jboss-seam-jpa.war to my WL 9.2 instance. I got the following: | | An error occurred during activation of changes, please see the log for details. | Message icon - Error [HTTP:101064][WebAppModule(jboss-seam-jpa:jboss-seam-jpa.war)] Error

Such as setting up the datasource with JNDI name examples-dataSource-demoPool as found in the persistence.xml file? Thanks for any insight.
