Check to make sure there isn't any extra whitespace at the top of your web.xml file.

From this exception it must be clear that your web.xml doesn't contain elements in expected order. I see you have given listener after servlet element. Validate the web.xml againt the DTD.

simple way to do validation for XML is open it using IE browser. If it opens fine. Then XML is well formed and sucessfully validated against DTD.

If it didn't open the full file then there is problem, check out the order as Purushothaman said.
