The exception stack trace you posted, was it displayed in your browser? If so, there should be a corresponding exception stack trace in the console log, please post that. Also, please post the source code for your servlet and for the web.xml file. When posting XML text or source code, enclose them in UBBCode "code" tags - you can do this by selecting the text and clicking the Code button above the editor window. Also, click the Preview button to ensure that the formatting is correct and the XML text shows up before posting.
