IF you are using maven (I asked on a comment without response), you can avoid conflictive jars using a "provided" scope. When you deploy it for production, jars are not included.

    javax.servlet
    jsp-api
    2.0
    provided


    javax.servlet
    servlet-api
    2.5
    provided

I'm not sure about jetty's jars but it's probably the same.

IF you are NOT using maven, you should move your conflictive jars (servlets and jetty) to your develompent container lib folder and remove them from your applications WEB-INF/lib folder.
