I have two things which you might want to try out: 1) You will lose your JSP debugging capability - but if that's not your concern, then in your CATALINA_HOME\conf folder append this for "JspServlet"
<init-param> <param-name>mappedfile</param-name> <param-value>false</param-value> </init-param> <init-param> <param-name>suppressSmap</param-name> <param-value>true</param-value> </init-param> This will stop generating JSR45 debug info and Symbol Maps for JSP pages ( I think I have said technical things right here, otherwise please correct me!). 2) I sincerely recommend moving scriptlet code out of your JSP and remove all unwanted/commented code, newline/carriages from your JSP. Even with the config above, this might fail since the code is genuinely too large for __jspService(). 3) If possible, try to use Ant and precompile your JSP and iterate through the .class files to check which method size is larger or close to 90% or the 64k footprint. You can write a short program by leveraging java.io and Apache commons BCEL library. Ant has a strange behaviour which doesn't throw any exceptions if the Jsp method size exceeds the limit. But the compilation occurs anyway. So you can go through those compiled files using your custom tool and print the size of the methods. I hope this helps you.
