I suspect that your WAR file includes the servlet API JAR file in WEB-INF/lib. If so, remove it.

The build-time classpath used by the IDE has nothing to do with the runtime classpath used by the server; you would do well to keep those separate.

I'm surprised JBoss would get confused over this, though - Tomcat knows not load javax.servlet classes that are part of individual web apps.

Your question has become an Eclipse question. What you need to know is how to include a JAR file in your Eclipse build path so that Eclipse can compile your code, but how to prevent Eclipse from packaging that JAR within your web application when you need to deploy it to the application server. Personally, I rarely use Eclipse to build or package my applications (I use Ant or Maven), so I can't tell you how to accomplish this (without first doing some research on this topic myself). Perhaps someone on the Eclipse forum will know. I'll cross-link you post to that forum.
 
It is sorta covered in the JavaRanch Style Guide.
