EL errors at proprietaryEvaluate method (Tomcat7)

[Praveen Boppana]

Hi,

I'm very new to tomcat7 environment, we are migrating from oc4j to tomcat7.
We have an issue with EL in jsp pages throwing error
"The method proprietaryEvaluate(String, Class, PageContext, null, boolean)
is undefined for the type PageContextImpl."

Tried setting the system property
-Dorg.apache.el.parser.SKIP_IDENTIFIER_CHECK=true in catalina.properties
file. Didn't resolve the issue. Page works fine after taking out EL
expressions.

Here is the EL expression we are using ${sessionScope.cachecontrol}

What are we missing?. Really appreciate your help.

Environment: Tomcat 7.0.37, jdk1.6.

Thanks
Praveen

jsp pages throwing error
"The method proprietaryEvaluate(String, Class, PageContext, null, boolean)
is undefined for the type PageContextImpl."

and a "root cause" part of your exception is... ?

The root cause is "Compilation error - it failing to compile the jsp page, if there is any EL in the page".
