I'm trying to embed OpenEJB 3.1 in my EJB3 application so that I can unit test my application. If it matters, I'm using NetBeans 6.5.
I followed the following instructions to setup Toplink Essentials as my OpenEJB persistence provider: http://qbeukes.blogspot.com/2008/08/toplink-as-your-openejb-persistence.html I removed the line of code that sets up toplink.target-server since OpenEJB 3.1 sets this up automatically. Additionally, I had to set the java.naming.factory.initial system factory: System.getProperties().setProperty("java.naming.factory.initial", "org.apache.openejb.client.LocalInitialContextFactory"); My problem: When I go to run my JUnit test on my Stateless EJB that is deployed within OpenEJB, everything goes fine until I try to persist an object from within the EJB method that is under test. I get a javax.naming.NameNotFoundException: Name "myDataSource" not found. myDataSource is the name of my data source from my persistence.xml, which is the same data source name that I used when setting up my InitialContext in my test code. It looks to me like the container is trying to inject a different myDataSource than the one that I created when setting up the InitialContext. See test results (with stack trace), source code, and XML files below. Any help is greatly appreciated! aflyctus /*********************************************** * Here's the NetBeans output with stack trace ***********************************************/ ------------- Standard Output --------------- Apache OpenEJB 3.1 build: 20081009-03:31 http://openejb.apache.org/ INFO - openejb.home = /home/aflyctus/netbeans-example/OpenEJBTest/modules/my INFO - openejb.base = /home/aflyctus/netbeans-example/OpenEJBTest/modules/my INFO - Configuring Service(id=Default Security Service, type=SecurityService, provider-id=Default Security Service) INFO - Configuring Service(id=Default Transaction Manager, type=TransactionManager, provider-id=Default Transaction Manager) INFO - Configuring Service(id=myDataSource, type=Resource, provider-id=Default JDBC Database) INFO - Found EjbModule in classpath: /home/aflyctus/netbeans-example/OpenEJBTest/modules/my/build/jar INFO - Beginning load: /home/aflyctus/netbeans-example/OpenEJBTest/modules/my/build/jar INFO - Configuring enterprise application: classpath.ear INFO - Configuring Service(id=Default Stateless Container, type=Container, provider-id=Default Stateless Container) INFO - Auto-creating a container for bean MyEJBBean: Container(type=STATELESS, id=Default Stateless Container) INFO - Configuring PersistenceUnit(name=myPU, provider=oracle.toplink.essentials.ejb.cmp3.EntityManagerFactoryProvider) INFO - Auto-creating a Resource with id 'myDataSourceNonJta' of type 'DataSource for 'myPU'.
