Are you using EJBs? If not, I would recommend jetty. jetty is a very light-weight container for doing most of the exploration/testing you would want to do in a project. Another plus that jetty delivers is that it is configured with only the most basic features enabled/configured by default.

Are you using Maven? If so, I would also recommend jetty-maven-plugin. In the past, I've had some success with using the jetty-maven-plugin for local testing on a previous project.
