Hi,

The following is the error:

The Bean is:

package com.titan.travelagent;

import javax.ejb.Stateless;
import javax.persistence.EntityManager;
import javax.persistence.EntityManagerFactory;
import javax.persistence.PersistenceContext;
import javax.persistence.PersistenceUnit;
import javax.persistence.FlushModeType;

import com.titan.domain.Cabin;

@Stateless
public class TravelAgentBean implements TravelAgentRemote
{
@PersistenceUnit(unitName="Test") private EntityManagerFactory factory;
@PersistenceContext(unitName="Test") private EntityManager manager;

public void createCabin(Cabin cabin)
{
manager.persist(cabin);
}

public Cabin findCabin(int pKey)
{
return manager.find(Cabin.class, pKey);
}

public void updateCabin(Cabin cabin)
{
manager.merge(cabin);
}

public void flushModeExample()
{
EntityManager createdManager = factory.createEntityManager();

try
{
Cabin newCabin2 = new Cabin();
newCabin2.setId(2);
newCabin2.setName("Another Cabin");
newCabin2.setBedCount(1);
createdManager.persist(newCabin2);

System.out.println("hello");
Cabin cabin2 = manager.find(Cabin.class, 2);
if (cabin2 != null)
{
throw new RuntimeException("newCabin2 should not be flushed yet");
}

Cabin cabin1 = (Cabin)createdManager.createQuery("FROM Cabin c WHERE c.id = 1").getSingleResult();

cabin2 = manager.find(Cabin.class, 2);
if (cabin2 == null)
{
throw new RuntimeException("newCabin2 should be flushed now");
}

createdManager.setFlushMode(FlushModeType.COMMIT);
newCabin2.setBedCount(99);

cabin1 = (Cabin)createdManager.createQuery("FROM Cabin c WHERE c.id = 1").getSingleResult();

manager.refresh(cabin2);
if (cabin2.getBedCount() == 99)
{
throw new RuntimeException("should not be 99 yet with COMMIT and a query");
}

createdManager.flush();

manager.refresh(cabin2);
if (cabin2.getBedCount() != 99)
{
throw new RuntimeException("should be 99 yet with a flush");
}
}
finally
{
createdManager.close();
}
}
}


The business Interface is:

package com.titan.travelagent;

import javax.ejb.Remote;

import com.titan.domain.Cabin;

@Remote
public interface TravelAgentRemote
{
public void createCabin(Cabin cabin) throws java.rmi.RemoteException;
public Cabin findCabin(int pKey) throws java.rmi.RemoteException;
public void updateCabin(Cabin cabin) throws java.rmi.RemoteException;
public void flushModeExample() throws java.rmi.RemoteException;
}


The Client code is:



package com.titan.clients;

import java.util.Properties;

import com.titan.travelagent.TravelAgentRemote;
import com.titan.domain.Cabin;

import javax.naming.InitialContext;
import javax.naming.Context;
import javax.naming.NamingException;

import javax.rmi.PortableRemoteObject;

public class Client_4
{
public static void main(String [] args)
{
try
{
Properties p = new Properties( );
p.put(Context.INITIAL_CONTEXT_FACTORY,
"org.jnp.interfaces.NamingContextFactory");
p.put(Context.URL_PKG_PREFIXES,
" org.jboss.naming:org.jnp.interfaces");
p.put(Context.PROVIDER_URL, "jnp://localhost:1099");

Context jndiContext = new InitialContext(p);
System.out.println(TravelAgentRemote.class.getName());
Object ref = jndiContext.lookup(TravelAgentRemote.class.getName());
TravelAgentRemote dao = (TravelAgentRemote)
PortableRemoteObject.narrow(ref,TravelAgentRemote.class);

dao.flushModeExample();
}
catch (Exception ne)
{
ne.printStackTrace();
}
}


}


Wud be a great help if you could help on this issue....

Mahtab:

I found that I had to create a jboss.xml for each app that had a
TravelAgentBean, and put it in resources\META-INF, and also build it into
the titan jar file that the TravelAgentBean was in.

<jboss>
 <enterprise-beans>
 <session>
 <ejb-name>TravelAgentBean</ejb-name>
 <jndi-name>TravelAgentRemote</jndi-name>
 </session>
 </enterprise-beans>
 <resource-ref>
 <res-ref-name>jdbc/MySqlWorkbookDS</res-ref-name>
 <resource-name>MySqlWorkbookDS</resource-name>
 </resource-ref>
</jboss>

I also separated the 'domain' and 'travelagent' class files into one
jar, called 'titan-ejb.jar', put that into the jboss deploy dir.
I then built a titan-client.jar with only the clients classes in it.

Hope this helps.
Tom.
