SEVERE: Error filterStart when deployed ajax4jsf onto tomcat

[terume]

Hi,

I tried to add ajax4jsf filter onto my web application using tomcat 6, it works fine on tomcat 5, but when I deployed it onto tomcat 6, the error message looks like:
org.apache.catalina.core.StandardContext start
SEVERE: Error filterStart
org.apache.catalina.core.StandardContext start
SEVERE: Context startup failed due to previous errors

Are there any difference between these two version's web.xml file? or I put the Filter configuration in the wrong place? I've already had ajax4jsf jar in WEB-INF/lib directory.

Here is my web.xml file:

Filters are the same, but your application must be different. Most probably it complains about classloader violation for el. You must have some exceptions somewhere in the log.
