[jboss-user] [EJB 3.0] - Re: EntityManager Injection, Null Pointer Exception. (Sorry.

[repkin]

I am so thankful for your helps, finally it worked.

This is the final situation:

I have changed ejb call part like that:


  | Context context = new InitialContext();
  | PrStaffInterface prstaff = (PrStaffInterface)context.lookup("surgeonfish/PrStaffHome/local");
  | prstaff.findById(new Integer(username));
  | 

And I have changed little part of persistence.xml


  | <persistence>
  | 	<persistence-unit name="time_report_persistence_context">
  | 		<provider>org.hibernate.ejb.HibernatePersistence</provider>
  | 		<jta-data-source>java:/time_reporting_data_source</jta-data-source>
  | 		<jar-file>/surgeonfish.jar</jar-file>-->this place changed
  | 		<properties>
  | 			<property name="hibernate.hbm2ddl.auto" value="create-drop"/>
  | 			<property name="hibernate.show_sql" value="true"/>
  | 			<property name="dialect">org.hibernate.dialect.MySQLDialect</property>
  | 			<property name="hibernate.transaction.manager_lookup_class" value="org.hibernate.transaction.JBossTransactionManagerLookup"/>
  | 		</properties>
  | 	</persistence-unit>
  | </persistence>
  | 

I have thought, I dont need to lookup. The ejb container is injecting, or intercepting at the object initialization and giving already created ejb object.

Thanks again.
