Hibernate - Help getting started with Hibernate

mikevdmza Oct 11, 2004 6:27 AM

Hi,

I am having trouble deploying an EAR that contains a HAR. I wonder whether anyone can help me get started with hibernate/jboss..?

My EAR looks like this:

myapp.ear
-META-INF/application.xml
-META-INF/jboss-app.xml
-jboss.har
--hibernate-service.xml
--mdbtest/ejb/Document.class
--mdbtest/ejb/Document.hbm.xml
-testClient.jar
-testEJB.jar

The console log shows the following null pointer exception:

10:56:11,463 INFO [EARDeployer] Init J2EE application: file:/usr/local/jboss-4.0.0/server/default/deploy/myapp.ear
10:56:11,901 INFO [EjbModule] Deploying SimpleMessageBean

hibernate-service.xml looks like this:

 <attribute name="Hbm2ddlAuto">create-drop</attribute>
 </mbean>
</server>

jboss-app.xml looks like this:

<?xml version="1.0"?>

<jboss-app>
 <module>
 <har>jboss.har</har>
 </module>
</jboss-app>

If anybody can help me set this up correctly, I would be HUGELY grateful :-)

I solved it by moving hibernate-service.xml into META-INF of the HAR file, and it worked. My mistake.

By the way, I hope this helps you further, http://forum.hibernate.org and its jboss topic rocks ! There are lots of users actively helping each other, lots of examples, common mistakes to learn from etc.

gumreal: I'm using JBoss 4.0.0

mikevdmza, thank you very much for your help.
My problem was that I made bad the structure of the .har file. Now, it works excelent.
