This is Apache Tomcat 6.x, supporting Servlet 2.5 and JSP 2.1. The Glassfish JSP 2.1 bundled in Jetty 6 is way too old. Retrieved from the file apache-tomcat-6.0.44-deployer.tar.gz minus the following files and directores: build.xml deployer-howto.html images/* lib/catalina* lib/jsp-api.jar (see below) lib/servlet-api.jar (see below) LICENSE (see ../../../licenses/LICENSE-Apache2.0.txt, it's also inside every jar) RELEASE-NOTES We could use the following API jars from Apache Tomcat 7.x, supporting Servlet 3.0 and JSP 2.2, that are required for Jetty 8, but we just bundle the ones from Jetty 8 instead: lib/jsp-api.jar lib/servlet-api.jar For more info: http://tomcat.apache.org/whichversion.html
