I have deployed all components of my EJB on JBoss 3.2.1 successfully. However, when I run the client, I see following the abover error message on the server, the details follow after the breif description of my setup:

I have a session bean (RegisterPlatesBean) that calls PlateBean(EntityBean). The problem comes when I am creating the platebean.

Here is the code:
Note: plateHome is set on the setsessioncontext of the session bean as follows:

Context ic = new InitialContext();
Object ref = ic.lookup ("PlateHome");
plateHome = (PlateHome)PortableRemoteObject.narrow (ref,PlateHome.class);

Here is the method that create plate entity bean:

private CloneTracking.DBObjects.Plate createPlate(String platename) throws CreateException, RemoteException {
CloneTracking.DBObjects.Plate p = null;

log("Creating Plate: " + platename);
p = plateHome.create(platename);
log("Successfully Created Plate: " + p.getPlatename());

return p;
}
________________________
Here is the code for PlateBean

public Long ejbCreate(String platename) throws CreateException
{

Connection con = null;
PreparedStatement ps = null;
ResultSet result=null;
int primarykeyid=0;
System.out.println ("Entering to create palte - " +platename);
try
{
con = DBConnection.getConnection ();
//Create Plate
//May need to Insert PlateOrientationObject
// Plate plate=plates;
ps = con.prepareStatement ("Select max(plateid) from Plate");
result=ps.executeQuery();
primarykeyid=result.getInt("PlatetId")+1;
ps =con.prepareStatement("insert into Plate (PLATEID, FREEZER_ID,RECEIVED_BY,CREATED_BY,PLATEFORMAT,PLATENAME,DESCRIPTION,CREATED_ON,RECEIVED_ON,ACTIVEYND,PLATEBARCODE) values (?,?,?,?,?,?,?,?,?,?,?)");
ps.setInt(1, primarykeyid);
ps.setInt(2,0);
// ps.setInt(3,plate.getReceivedby().intValue());
ps.setInt(3,0);
// ps.setInt(4, plate.getCreatedby().intValue());
ps.setInt(4, 0);
// ps.setString(5, plate.getPlateFormat());
ps.setString(5, "96");
ps.setString(6, platename);
ps.setString(7,"Test");
ps.setDate(8,new java.sql.Date(System.currentTimeMillis()));
ps.setDate(9,new java.sql.Date(System.currentTimeMillis()));
ps.setString(10, "Y");
ps.setString(11, "1234567");
if (ps.executeUpdate()!= 1)
{
throw new CreateException ("Failed to add Aliquot to database");
}
else
System.out.println ("ID value= " +primarykeyid);

// plate.setPlateID(primarykeyid);

return new Long(primarykeyid);

}
catch (SQLException se)
{
throw new EJBException (se);
}
finally
{
try { ps.close (); } catch (Exception e) {}
try { con.close (); } catch (Exception e) {}
}
}
