    Multiple Persistence Unit

    Raghu Govindaraj Newbie


      I am trying to access 2 different datasources in my EAR. We have a MySQL database for all the standard operations, i am now trying to access a few tables from a differnt datasource.

      The primary tables are accessed without a persistenceUnit, by using theDefaultDS configured. (i.e. I did not provide a unitName while creating the EntityManager)

      So I added a persistence.xml to the META-INF with the following lines assuming the new entities and bean will use the unit-name provided in the persistence.xml. I have one entity called T1 and a bean to access it.

      <?xml version="1.0" encoding="UTF-8"?>
       <persistence-unit name="ragsDemo">
       <property name="hibernate.dialect" value="org.hibernate.dialect.MySQLDialect"/>
       <!-- <property name="hibernate.hbm2ddl.auto" value="create-drop"/> -->
       <!-- <property name="hibernate.hbm2ddl.auto" value="update"/> -->

      In the bean code i am creating the Entity manager using the following lines

       EntityManager em;

      But when I deploy I am getting the following error :

      --- MBeans waiting for other MBeans ---
      ObjectName: jboss.j2ee:service=EJB3,name=com.rags.test.T1AccessBean
       State: FAILED
       Reason: java.lang.RuntimeException: unable to find: java:/managedEntityFactories/ragsDemo

      I am using JBoss 4.0.3 SP1, can somebody tell me where I am going wrong.
