JNLP app using ejb - OutOfMemoryError

Question

I have an application, fully signed, that connects to a
database on the same intranet, using ejb's.
When the user clicks on icons, the system loads data from the database into various tables. each data object type does a separate access to the database.
When the app is run in Oracle 9i JDeveloper it works fine but when I deploy over JNLP I get an out of mem error after the first access. This first access seems to work fine.
I have tried to increase the initial and max heap sizes in the jnlp file but all this does is take longer for the out of mem error to be thrown.
There doesnt seem to be any problem with loading up classes and Im stumped.
Below is some sample code used for one of the entity objects, used to access the ejb's.
  public Vector getArisingList(String aircraftID)
    try
      Vector v = getEjb().getArisingList(aircraftID);
      clearEjb();
      return v;
    catch (Throwable e)
      e.printStackTrace();
    return null;
  } and get/clearejb() go like this..  private ArisingService1 getEjb()
    if (ejb == null)
      try
         ejb = lookupHome().create();
      catch(Throwable e)
        e.printStackTrace();
    return ejb;
  private ArisingService1Home lookupHome()
    ArisingService1Home home = null;
    String ejbUrl = "ArisingService";
    try
      Context ctx = new nazca.NazcaRemoteContext().getContext();
      home = (ArisingService1Home)ctx.lookup(ejbUrl);
    catch (Throwable e)
      e.printStackTrace();
    return home;
  // for use after each call to getEjb so the session is cleared on the server
  private void clearEjb()
    try
      ejb.remove();
    catch(Throwable e)
      System.err.println("Cound not call ejb.remove()");
    ejb = null;
  }   Does anyone know what is going wrong?
Should I be clearing up some ejb stuff that im not?
Thanks in anticipation
