  Workaround:
  
  For some reason the web.xml is wrong for a Dynamic Web project i
  t's missing the version.
  ?web-app xmlns='http://java.sun.com/xml/ns/j2ee' xmlns:xsi='http
  ://www.w3.org/2001/XMLSchema-instance' xsi:schemaLocation='http:
  //java.sun.com/xml/ns/j2ee http://java.sun.com/xml/ns/j2ee/web-a
  pp_2_4.xsd' id='WebApp_ID'?
  
  it should be
  ?web-app xmlns='http://java.sun.com/xml/ns/j2ee' xmlns:xsi='http
  ://www.w3.org/2001/XMLSchema-instance' xsi:schemaLocation='http:
  //java.sun.com/xml/ns/j2ee http://java.sun.com/xml/ns/j2ee/web-a
  pp_2_4.xsd' id='WebApp_ID' version='2.4'?
  
  
  To workaround this issue have the customer edit the web.xml and
  add the version='2.4' like the second xml snippet above.
  
  Defect submission:
  The customer should be seeing a more meaningful message than a n
  ullpointer exception. This will only post a message that the ver
  sion is incorrect, the  web.xml will still have to be fixed.
