Problem solved: Due to an error in my ant target for precompiling JSP
which was hidden by the fact that I had Netbeans test compiling the JSPs,
the end result was that the JSP was precompiled using Netbeans JspC
instead of jasper JspC. Netbeans 6 JspC is apparently a few generation
newer than that of jasper in Tomcat 5.5 and generates incompatible
results.
Thanks,

Problems with precompiled JSP on Tomcat 5,5
Hi all, I am having a problem with some precompiled JSP files on Tomcat
5.5 (problem not observed on 6.0). Below is the description:
Target environment:
OS: Linux CentOS 4.5
Tomcat: 5.5.26
JDK: 1.5.0_08 & 1.6.0_10
The error:

The JSP:

Any pointer would be greatly appreciated,
