Subject Configuring JSF in the TOMCAT/conf/web.xml for all webapps
Date Fri, 02 Feb 2007 18:10:22 GMT
Hello,

I am developing a system in which every webapp deployed to Tomcat uses JSF.
So, I decided to move the common JSF configuration from each 
webapp/WEB-INF/web.xml
into the TOMCAT/conf/web.xml file.

At startup time everything looks fine.  Here's an example of the output 
I see for each webapp:
-------------------------

However, when the first URL to *.jsf occurs I get the following error

-------------------------

If I move the JSF configuration back into each webapp-specific web.xml,
then it works fine.  Any ideas why this would happen?

Thanks,
Bryan
