Sounds like one time pre-compilation is achievable. Thanks for the tips. On the perm gen saving issue, all shared jars and classes are under the shared class loader already (shared/lib). I see what you're saying about possible problems with the common class loader, but would it be possible to move the compiled JSPs under the shared class loader? If so how would you go about doing that?

Well you could *try* to move those precompiled JSP to the common classloader, but i would expect lots of troubles doing it. You could also *try* to move all your application to common classloader, but be very careful, some J2EE framework user singleton patterns and as such must be in separated classloaders. --------------------------------------------------------------------- To start a new topic, e-mail: users@tomcat.apache.org To unsubscribe, e-mail: [EMAIL PROTECTED] For additional commands, e-mail: [EMAIL PROTECTED] --------------------------------------------------------------------- To start a new topic, e-mail: users@tomcat.apache.org To unsubscribe, e-mail: [EMAIL PROTECTED] For additional commands, e-mail: [EMAIL PROTECTED]
