Hi,
You know, there is a flag in tomcat/conf/web.xml on the jasper config :
<init-param>
<param-name>enablePooling</param-name>
<param-value>false</param-value>
</init-param>
So you shouldn't need to disable tagpooling in tomcat source before compiling it.
I've always had a problem with tagpooling and using the osCache (www.opensymphony.com)
library. For some reason it does not work correctly with tomcat, so I have to disable
tagpooling too.
