Am a novice and i have been trying to write a simple program
to save three html form data ( name, email, age) to an access
database using javabean and jsp. After days of struggling and
reading tutorials from the net, i have succeded in debuging all
error messages. my program is runing but the form data entered
is not being saved into the access database. can some one examine
my codes and tell me what to do and where I went wrong. yur help
will be very much appreciated.
Thanks
