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

Did you install the JSF facet when you created the dynamic web project?
That should cause the addition of the JSF libraries.

Can you show me your web.xml and faces-config.xml files? Also, which JSF
implementation are you using (i.e. where did you download it from).

Please check if you have any of the JSF libraries in a folder with spaces
in its name. I recollect getting similar errors with Tomcat 6.0.

JSF facet is installed in Eclipse.

web.xml:

</faces-config>

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. :(

I am able to get a basic page working with your web.xml and
faces-config.xml, so it must be a configuration problem. Classpath (JSF
library) is a good candidate. What version of WTP/JSF tools are you
using? What jars are in your implementation JSF library?
