I have managed to narrow it down to that this driver may not support username and passord in the URL.
I have used another driver (db2jcc) which supports the user and password in the string and now I'm getting:
Mon Jun 16 06:30:19 BST 2008:ERROR:An error occured [[ibm][db2][jcc][10103][10941] Method executeQuery cannot be used for update.], see error log for details
This is the SQL I'm using:
"SELECT * FROM YESNONA"
I'm really frustrated with this. I would want to purchase soapUI pro and get started with my testing, but I really can't do any testing with a DB connection.
Any help would be very much appreciated.
