Transaction across several different methods in Session beans

[Lopez Esteban]

Hi all,
I'm trying to use UserTransactions in a stateful session bean to associate
itself with a transaction across several diferent methods, but it does not
work. My code is:

Stateful Session Bean:
public class TransactionBean implements SessionBean
{
  private SessionContext ejbCtx;
   private Entity entityRole = null;
 
  public void setSessionContext(SessionContext context)
    throws RemoteException, EJBException
  {
      ejbCtx = context;
  }

  public void ejbActivate() throws RemoteException, EJBException
  {
  }

  public void ejbPassivate() throws RemoteException, EJBException
  {
  }

  public void ejbRemove() throws RemoteException, EJBException
  {
  }

  public void ejbCreate() throws CreateException, EJBException,
RemoteException
  {
  }


  public void createEntity(String id)
  {
    try
    {
      Context context = new InitialContext();
      EntityHome entityHome =
(EntityHome)PortableRemoteObject.narrow(context.lookup("java:comp/env/entity
"),
        EntityHome.class);
      ejbEntity = entityHome.create(id);
    }
    catch (Exception ne)
    {
      ejbEntity = null;
      ne.printStackTrace();
    }
  }

  public void setDescription(String description) throws RemoteException
  {
    if (ejbEntity == null)
    {
      throw(
        new RemoteException("Entity is null, use createEntity() first"));
    }
    try
    {
      ejbEntity.setDescription(description);
    }
    catch (RemoteException re)
    {
      re.printStackTrace();
    }
  }

  public void begin()
  {
    try
    {
      utx = ejbCtx.getUserTransaction().begin();
    }
    catch(Exception e)
    {
      e.printStackTrace();
    }
  }

  public void commit()
  {
    try
    {
      ejbCtx.getUserTransaction().commit();
    }
    catch(Exception e)
    {
      e.printStackTrace();
    }

  }

  public void rollback()
  {
    try
    {
      ejbCtx.getUserTransaction().rollback();
    }
    catch(Exception e)
    {
      e.printStackTrace();
    }
  }
}

and my client is:

public class TransactionTest
{
  public static void main(String[] args)
  {
    try
    {
      Context context = new InitialContext();
      TransactionHome home =
(TransactionHome)PortableRemoteObject.narrow(context.lookup("java:comp/env/t
ransaction"),
        TransactionHome.class);
      Transaction tx = home.create();
      tx.begin();
      tx.createEntity("tx entity");
      tx.setDescription("tx description");
      tx.commit();
    }
    catch (Exception e)
    {
      e.printStackTrace();
    }
  }
}

I'm using Orion 1.4.4 and Windows 98. I set
<transaction-type>Bean</transaction-type> in the ejb-jar.xml of Transaction
Bean and
                <container-transaction>
                        <description/>
                        <method>
                                <description/>
                                <ejb-name>entity</ejb-name>
                                <method-name>*</method-name>
                        </method>
                        <trans-attribute>Required</trans-attribute>
                </container-transaction>

for Entity bean.

When I try to use this I catch the folow exception:
java.lang.IllegalArgumentException: No active Transaction
        at
com.evermind.server.ApplicationServerTransactionManager.commit(JAX)
        at transaction.TransactionBean.commit(TransactionBean.java:127)
        at
Transaction_StatefulSessionBeanWrapper0.commit(Transaction_StatefulSessionBe
anWrapper0.java:190)
        at java.lang.reflect.Method.invoke(Native Method)
        at com.evermind.server.rmi.bf.do(JAX)
        at com.evermind.util.f.run(JAX)

Any ideas.
Thanks, Esteban
