Tomcat 6.0.18 Setup Issues - JasperException: Unable to compile class for JSP

Hi,

I'm trying to port a project that was running on Tomcat 5.0.25 to Tomcat 6.0.18. I have very little experience doing this before and am running into various problems, primarily to do with compiling my jsp files. From my stack trace I'm getting errors such as:

Appreciate any tips or guidance,
