    failed to resolve persistence unit(JBoss 5.1)

    crazyit May 16, 2010 3:02 AM

      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

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
find a persistence unit named 'newsUnit' in AbstractVFSDeploymentContext@5205507
{vfsfile:/D:/jboss-5.0.1.GA/server/default/deploy/news.ear/}

       

      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.
