The error message contains the answer to your problem: -

See Servlet Spec 2.3, section 9.7.2. Offending class: javax/servlet/Servlet.class

This section of the specification says that a web application is not allowed to override J2SE or J2EE classes e.g. classes in the java.* and javax.* namepsaces.

You have included 'javax.servlet.jar' in your war so as the war is validated it looks as if you have attempted to override 'javax/servlet/Servlet'.

The solution is to remove the jar from your archive.
