    SQLGrammarException after deploy

      Hi guys,

      I am developing a small enterprise application using EJB3.0 and JSF, and I plan to use JBoss as my AS. I use Oracle's JDeveloper as my IDE at the moment and my DB is Oracle DB. When deploying my application with JDev's embedded OC4J AS, everything works fine, there is not any problem.

      I tried to pack and deploy my application to JBoss but faced with problems. First, I got the "$ProxyXX ClassCastException" when looking up remote stateless EJBs from JNDI. I solved this problem by changing "CallByValue" sections to "true" in the "jboss-service.xml" and "ear-deployer.xml" configurations.

      Now I do not get that ClassCastExceptionError but this time I get an SQL Error from Oracle which I suppose stems from JBoss's naming the remote entity beans such as "ENTITYBEAN0_"."PROPERTY". In my case the exception is like this one:

      "10:04:32,096 WARN [JDBCExceptionReporter] SQL Error: 904, SQLState: 42000
      10:04:32,096 ERROR [JDBCExceptionReporter] ORA-00904: "MYENTITY0_"."TYPE": invalid identifier

      10:04:32,189 ERROR [STDERR] javax.ejb.EJBException: javax.persistence.PersistenceException: org.hibernate.exception.SQLGrammarException: could not execute query..."

      I do not know why there is a 0 (zero) at the end of the entity name "MYENTITY", and I suspect this exception is related to that.

      I would be very pleased if you can give your opinions on this problem...

      Thank you.
