Any success/failure stories with tomcat's deployer to pre-compile the Webtop JSP pages ?

Buddy

Hi there,

Has anybody pre compiled the Webtop/WDK JSP pages ?

As far as I understand, on a clean deployment, that should speed up a lot the 1st time a user accesses a JSP page since it would already be compiled.

anybody can confirm or not ?

Does it works ?

If yes, would you share your build file ?

TIA,

Bud

Nailed it

Note that the parameter used by jasper, poolingEnabled is different than the one in the tomcat web.xml, enablePooling

Here is the build.xml file I used

Note that I only compiled, started Tomcat and went to the Webtop login screen. Didn't get any error but didn't perform a full test either
