Hi,
You have mismatched versions of the Servlet API jars around. There
should be only one, in tomcat's common repository. Don't ship the
servlet or JSP API jars with your webapps. And if you stored references
to objects from old versions of these APIs in your Sessions, junk the
session repository (session.ser).

Subject: Tomcat 4.1: JSP pages don't always compile the first time?
We have a large JSP-based application which we're noting some first
time
compilation problems.
When we deploy the .war file (with the "work" cache deleted and Tomcat
freshly started) some of our pages (but not all) fail to compile upon
the first access with the error below.
If you simply refresh the page through the web browser it then compiles
fine, and is fine from that point onwards. It always happens with the
same pages. These pages have includes of other JSP pages, but these
have
all already been correctly compiled and previously accessed.
Can anyone give me any ideas on this? I can't find anything similar
after trawling the search engines?
Thanks,
Richard
