This is a bit insane I must say. I have the following setup: Eclipse Helios, 64-bit JDK (1.6.0_21), Tomcat 6 (6.0.29), and a pretty straightforward JSP that does nothing other than evaluate the date.
I get this crap all the time:

I have checked everything I can think of (JAVA_HOME, CATALINA_HOME variables) and all check out okay. The project in eclipse is a dynamic web project and has all the $CATALINA_HOME/lib jar files in it including the el-api.jar file.
So what gives? The real annoying thing about this whole process is that I can export the war file, pop it onto my windows machine and it works just fine! I tried doing the same with Tomcat on Ubuntu and running it from there directly but am no better off. So, anyone know what the heck I am doing wrong?
