Batchupdate fails in DB2/400

Question

Hi
I�m trying to do a batchupdate in an DB2/400 table but when I try to insert I get an error that there�s a duplicate key value and the update fails. This is normal behavior as indeed the program should only add a record if it doesn�t exist yet, if it does, it should move to the next record. I use this code:
�
String cmd= "INSERT INTO TABLE1(IBY58IAWB)VALUES (?)";
AS400stat = AS400Conn.prepareStatement(cmd);
     while (rs.next())
     AS400stat.setString(1,rs.getString(1));
     AS400stat.addBatch();
     int[] updateCount=AS400stat.executeBatch();
     AS400stat.clearBatch();
�
catch (BatchUpdateException b)
     System.out.println("error: " + b.getErrorCode());
     For(int x=0;x<b.getUpdateCounts();x++)
System.out.println(getUpdateCounts[x]);
     return;     
the problem is that the errorcode returned is 0 and getUpdateCounts returns no elements, so the program stops executing.
I�m using the IBM ODBC-JDBC bridge, which supports batchupdates. I know some drivers continue executing the batch even when an error occurs, obviously this one doesn't
Thanks for your help!

Surely you should just use executeUpdate(), catch and ignore the duplicate key exception.
As far as I can remember, the JTOpen driver(http://www-124.ibm.com/developerworks/oss/jt400/) behaves the same.
