I'm getting the following stack trace on a jsp page that's only doing
a c:set.
I'm guessing that perhaps I'm missing an EL jar? It runs fine under
jetty from within maven with "mvn jetty:run" and it runs fine within
eclipse using the embedded tomcat. But when I run it with the Google
App Engine Development Web Server via "appengine-java-sdk\bin
\dev_appserver.cmd war" then I get the EL error.
My index.jsp that it's blowing up on is as follows. Below that is the
stack trace.
Thanks for your help.
