There is a syntax error in your web.xml. Since you haven't shown that it is difficult to determine the exact problem. However, check that the order of elements matches the order of elements listed. For example, you cannot have servlet-mapping tags appear before the servlet tags, and so on. Have your servlet tags grouped together and appear before your group of servlet-mapping tags, and so on with the other tags.
