You are probably using JServ with the wrong version of the Servlet Library. JServ supports Servlet API 2.0 and is not forward compatible with the newer version shipped with Cocoon. Cocoon is Servlet API 2.2 compatible and requires the servlet_2.2.jar package to compile correctly, but works is back compatible with old servlet engines. To fix the problem you must set the Servlet API 2.0 version in your classpath instead of the one shipped with Cocoon. Read the JServ installation instructions for more info on this.
