Seems to me that the cause is a missing library in your classpath. Specifically, you have some classes annotated with @javax.persistence.PersistenceUnit, but this class is missing from the classpath. So I suggest you list all the libraries deployed in the test webserver (including the /lib libraries) and compare them with the ones deployed in your local server, paying special attention to some of these:

  • persistence.jar
  • javaee-api-*.jar
  • annotations-api-*.jar

.. which are the standard libraries in which javax.persistence.PersistenceUnit class might be present.
