Answer 1

My observations:
* I cannot see your resultset being declared as updatable anywhere.
* You should print out the stack trace while developing an application. It is usually more informative than just printing the exception message.
* Your JDBC resources are not being handled properly.
The first observation pertains to the problem at hand, I suppose.
