I see :-)

=== description ===

I am using the ant script I found on page
<http://jakarta.apache.org/tomcat/tomcat-4.1-doc/jasper-howto.html>. The 
relevant software I use is Tomcat 5.0.26 (the one that comes with JBoss 
3.2.5) and JSF 1.1_01 reference implementation (the latest release).

BTW: Is there a way to let Tomcat do the job of JSP compilation on 
deployment? I mean without the need of visiting each page manually?

=== stack trace ===
