My Remote interface is like this:

package com.title.travelagent;
 
import javax.ejb.Remote;
import com.title.domain.Cabin;
 
@Remote
public interface TravelAgentRemote
{
public void createCabin(Cabin cabin);
public Cabin findCabin(int id);
public void updateCabin(Cabin cabin);
public void flushModeExample();
}

My persistence.xml looks like this:

<persistence>
<persistence-unit name="titan">
<jta-data-source>java:/DefaultDS</jta-data-source>
<properties>
<property name="hibernate.hbm2ddl.auto" value="create-drop"/>
</properties>
</persistence-unit>
</persistence>

My jboss.xml is like this:

<jboss>
<enterprise-beans>

 
<session>
<ejb-name>TravelAgentBean</ejb-name>
<jndi-name>TravelAgentRemote</jndi-name>
</session>


<session>
<ejb-name>TransactionPersistenceContextBean</ejb-name>
<jndi-name>TransactionPersistenceContextRemote</jndi-name>
</session>
 
<session>
<ejb-name>ExtendedPersistenceContextBean</ejb-name>
<jndi-name>ExtendedPersistenceContextRemote</jndi-name>
</session>

</enterprise-beans>

</jboss>

And my titan.ear folder structure is like this:

titan
|--META-INF
| |- persistence.xml
| |- jboss.xml
|
|- class files with proper pckg structure

Rest things are set in class path via an ant file

Please let me know..

[Ram Venkat]

place jboss.xml in your ejb-jar like jboss.xml

 
<jboss>
   <enterprise-beans>
      <session>
         <ejb-name>LogonSessionBean</ejb-name>
         <jndi-name>LogonSessionBean</jndi-name>
      </session>
   </enterprise-beans>
   <enterprise-beans>
      <session>
         <ejb-name>TravelAgentBean</ejb-name>
         <jndi-name>TravelAgentBean</jndi-name>
      </session>
   </enterprise-beans>
</jboss>
