Hi, I'm using ZK 3.6.1 and zuljsp 1.2.0. I got the following exception when startup the server (Environment: Tomcat5.5.28, jdk1.5.0_19):

>> ZK Jsp spec v2.0 JspFactory initializing...

When I run the application on Tomcat6 everything is ok:

>>> ZK Jsp spec v2.1 JspFactory initializing...
current spec version:2.1
>>> ZK Jsp spec v2.1 JspFactory initialized.

Please help !!!
