Hello David, I included all jar & zip files on my computer, including j2ee.jar and I'm still having the problem. I have just noticed a weird behaviour though, if I try to reload the jsp right after the jsp fails the first time it seems to run without throwing the exception. If I restart Tomcat and try again the problem starts again. I could get this to work in theory by forcing it to run through the code once on startup but I shouldn't have to do that and I honestly would prefer getting it to work as it should.
