Subject RE: ClassCastException org.apache.jasper.runtime.ELContextImpl cannot be cast to org.apache.jasper.el.ELContextImpl
Date Fri, 03 Aug 2012 05:51:51 GMT
May be this particular line in JSP is attempting to perform an action which the container is
unable to process as a Servlet class. Just cross check the JSP code once. What does the <c:out
value="${fn:length(promoCodeSpecCommand.user)}" /> do? Is it a directive? Or a call to
some function?

Regards
Mansukhdeep

Hi,

I'm seeing this problem below appearing now with one of our web-apps, google has not helped
me so far... There have been no changes with the web app in question, which was working, so
I'm picking something is going on with either the tomcat or OS (virtualized) environment,
but what? Any tips as to how to figure out what is going on?

root cause

java.lang.ClassCastException: org.apache.jasper.runtime.ELContextImpl cannot be cast to org.apache.jasper.el.ELContextImpl

The app is deployed on Tomcat 7.0.27, java 1.6_026, erroring jsp line:

<c:out value="${fn:length(promoCodeSpecCommand.user)}" />

Thanks

Dale
