--------------------------

                 Key: JBAS-8036
                 URL: https://jira.jboss.org/browse/JBAS-8036
             Project: JBoss Application Server
          Issue Type: Bug
      Security Level: Public (Everyone can see)
         Environment: JBoss 5.1.0 GA
            Reporter: Dave Chen


create a new persistence unit programmatically and map it to a new datasource without redeploy or server restart. 
We tried the following in a stateless session bean:

Map configOverrides = new HashMap();
EntityManagerFacotry emf = Persistence.createEntityManagerFactory("unit1", configOverrides);

But got exception:

javax.persistence.PersistenceException: [PersistenceUnit: unit1] Unable to build EntityManagerFactory

<persistence-unit name="unit1">
 <jta-data-source>java:/dataSource1</jta-data-source>
 
 <properties>
 <property name="hibernate.dialect" value="org.hibernate.dialect.MySQLDialect"/>
 <property name="hibernate.hbm2ddl.auto" value="update"/>
 <property name="hibernate.show_sql" value="false"/>
 </properties>
 </persistence-unit>
