    Accessing DataSource configured in JBOSS 7..urgent!

    Amit Mehra Newbie

      Hi ,


      I have configured a datasource in my JBoss AS 7 as a "module" as a JNDI name  java:jboss/ScoringEngineDS as seen below:




      This server is in my local machine. This points to a MySQL database driver which is also present in same local machine.


      i made entry in the " persistence.xml" of my application as show below :



      the war of my application gets deployed successfully on the server. But when i am trying to run my application(a web service) it throws me this exception :


      SEVERE: Could not find datasource: java:jboss/ScoringEngineDS

      INFO: Building entityManagerFactory failed.javax.persistence.PersistenceException: [PersistenceUnit: ScoringEnginePersistenceUnit] Unable to build EntityManagerFactory


      I am creating a EntityManagerFactory using the PersistenceUnit defined in persistence.xml

      Where am going wrong? What is the correct way to connect to such a datasource?


      I also added a "jndi.properties" files to my classpath containing :

      #jboss JNDI properties




      if i add : java.naming.provider.url=jnp://localhost:1099 , it is throwing me another exception on this.


      Kindly provide your inputs on this..its urgent!!!
