A couple of things to help you get better and faster answers:
Please be sure to take the time to compose descriptive subjects for your posts. You will attract people who will can give you better and faster answers when your posts have good, descriptive subjects. For more information, please click this link ⇒ UseAMeaningfulSubjectLine. Using a title of "Servlet" in a forum completely dedicated to questions on servlets isn't going to attract the attention of those who can best help you.
I have changed the subject to one that's more suitable; please use it as an example for future posts.
Please be sure to use code tags when posting code to the forums. Unformatted or unindented code is extremely hard to read and many people that might be able to help you will just move along to posts that are easier to read. Please click this link ⇒ UseCodeTags ⇐ for more information. Properly indented and formatted code greatly increases the probability that your question will get quicker, better answers.
I've gone ahead and added the code tags for you. See how much easier the code is to read? Though it would be much easier if you used proper indentation in your code.
Your code eats the exception. So what happens to the response in such a case?
In a web app, exceptions should be allowed to propagate outwards until they reach a central error handler defined in the deployment descriptor that can show a user-freindly "oops" page to the user, while logging the error properly for development to diagnose.
