Hi there!   I am trying to execute an insert query on Access database. I am using JWS 2.0. However, when I submit my form, it accesses web server and throws 500 Error. I am using Windows NT Workstation. I am trying to print some trival sentences, but even those are not being displayed. Can somebody plz help me in solving this riddle.   Regards, Rajneesh Garg   Keep Smiling.
