Thanks Thanks a lot. Yep that was it. I had all sorts of constructors but the default one. Upon adding that along with the other constructors that I had removed, it worked!. YIPPEEE! As for R J Scheuerle's reply to have found the field 'password' and bean accessors as 'setPasswd', I apologize as that was just a temporary change I had made to see if it changed the soap message and I forgot to correct it before posting the message. I appreciate your time for replying me though.
