      I have an application that used to work with WebLogic 10.3.2 well

      but it fails starting with JBoss 5.1 GA with the following exception :

       

      org.jboss.deployers.spi.DeploymentException: Error deploying news.ear: Container jboss.j2ee:ear=news.ear,jar=news.ear,name=newsEao,service=EJB3 failed to resol
      e persistence unit newsUnit

      DEPLOYMENTS IN ERROR:
        Deployment "vfsfile:/D:/jboss-5.0.1.GA/server/default/deploy/news.ear/" is in
      error due to the following reason(s): java.lang.IllegalArgumentException: Can't

      My persistence.xml file is in a JAR file bundled in the EAR I try to deploy :

       

      <?xml version="1.0"?>
      <persistence version="1.0" xmlns="http://java.sun.com/xml/ns/persistence"
           xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance"
           xsi:schemaLocation="http://java.sun.com/xml/ns/persistence 
           http://java.sun.com/xml/ns/persistence/persistence_1_0.xsd">
           <persistence-unit name="newsUnit" transaction-type="JTA">
                <jta-data-source>java:/firstds</jta-data-source>
                <class>org.crazyit.model.News</class>
                <properties>
                     <property name="hibernate.dialect" 
                          value="org.hibernate.dialect.MySQLInnoDBDialect"/>
                     <property name="hibernate.show_sql" value="true"/>
                     <property name="hibernate.format_sql"
                          value="true"/>
                     <property name="hibernate.hbm2ddl.auto"
                          value="update"/>
                </properties>
           </persistence-unit>
      </persistence>
      
      
      

       

      I trying to inject the persistence Context into a EJB which in the same EJB-JAR,

       

      @PersistenceContext(unitName="newsUnit")
       private EntityManager em;
      

       

      if I deloy the EJB-JAR  on JBoss 5.1 , the EJB-JAR works well.

       

      but if I package the EJB-JAR into a application which include a web app, then throw such Exception.
