If it's a JSP with lots of tags, then Jasper 1 generated code which triggered a performance bug in the virtual machine (dealing with try/catch nesting). You can notice the issue by taking Jasper 1 JARs, putting them in TC 4.1, and notice (on Sun VMs, I don't know about others) pages taking 10x or more the usual time to render. Upgrade to 4.1 or 5.0 if this is the problem. -- xxxxxxxxxxxxxxxxxxxxxxxxxxxxx Rémy Maucherat Senior Developer & Consultant JBoss Group (Europe) SàRL xxxxxxxxxxxxxxxxxxxxxxxxxxxxx --------------------------------------------------------------------- To unsubscribe, e-mail: [EMAIL PROTECTED] For additional commands, e-mail: [EMAIL PROTECTED] --------------------------------------------------------------------- To unsubscribe, e-mail: [EMAIL PROTECTED] For additional commands, e-mail: [EMAIL PROTECTED]
