Hello there,
Pardon my ignorance, I am new to Eclipse and JSF.
I followed the steps from this webinar
https://admin.adobe.acrobat.com/_a300965365/p87371911/ to create a demo app.
However when I click on a jsp file and select Run As -> Run on Server, I am
getting a nasty error from Tomcat:

My guess is that JSF jars are not included in the deployed app. If so, how I
do tell Eclipse to do that?
I am running Eclipse 3.3 with Tomcat 5.5 (java jre1.5.0_10).
Thanks,
Dennis

JSF libraries do not have spaces in their names.
One strange thing: I've been testing on Tomcat 5.5. Then I installed 6.0 -
same issue. Tried 5.0 - works! Unfortunately I would like to use java 1.5,
which is not supported by tomcat 5.0 as far as I understand. :(
