This week's book giveaway is in the OCPJP forum. We're giving away four copies of OCA/OCP Java SE 7 Programmer I & II Study Guide and have Kathy Sierra & Bert Bates on-line! See this thread for details.
If you mean "can you somehow invoke the service() or doPost()" method to display the results of the error -- the answer is no, you can't do that. You'll have to bubble the exception up to the servlet that originally was called and handle it there. I think you might have a more interesting question here. Is your question really "how do I handle exceptions in Servlet programming and display errors properly?"
