Any way to pre-compile JSPs in Tomcat
As per the subject line, can I configure Tomcat to pre-compile the
JSPs before we ship out a .war file?
thx,
Fred

Good to know. Is there any checking done before running a JSP that has
been precompiled? That would seem to be a good thing to do. If such
checking isn't being done, I'd be happy to propose a solution and maybe
submit a patch.

Nope. pre-compilation ties in Tomcat internals which can, and have,
varied between point releases.

Do you mean that you'll need to use a matching version in order to enjoy
all the benefits and features of that version, or is there something
more sinister?
I would expect that you can pre-compile JSPs into servlets that will run
on any servlet container using the same servlet API version and tag
library versions (including JSTL, which might vary from Tomcat-to-Tomcat).

Please note, though, that
1. You must use exactly the same version of Tomcat (x.y.z) as the one
where you will be deploying your war file.
2. Some Jasper options and system properties affect compilation. It is
unlikely that that will be a concern for you, though.
3. It is possible to precompile JSP pages of a web application that is
already deployed on the web server. See chapter JSP.11.4.2
"Precompilation Protocol" in the JSP 2.1 specification.

The catalina-tasks.xml file in tomcat/bin contains some importable ant
tasks.
