The code below catches my SQl exception as expected, and shows the user an Error JSP Page with some info on it, but the servlet continues and does some other processing. I don't want this other processing to continue. If I add a "return;" as the last line in this snip it of code , it appears to work, but I'm on my own
and I need to know if this is the way to accomplish this ? And what does "return;" actually do in this case ? Thanks
You haven't been clear on what's happening that you're not expecting. Sure if you handle the exception then procession will contain as normal. That's just standard Java.
Backing up a bit, I would not be handling the exception in the servlet in this manner. Rather, I'd wrap the exception in a ServletException and let it propagate outward to be handled by a central error handler registered in the deployment descriptor.
