JSF Intro Tutorial - Error Message: "Error instantiating web-application"

Question

Hi all there !
I find JDeveloper a very good tool to learn how to produce websites.
I 've just started with the tutorials.
Specifically: http://www.oracle.com/technology/obe/obe1013jdev/10131/jsfintro/jsfintro.htm
The problem I found is in Runing the application section:
"1. ...Right-click /welcome.jsp in the diagram (faces-config.xml) and select Run from the context menu."
The OC4J server starts, shows a lot of messages (warnings, errors, etc.) in its Log, open Firefox Navigator and shows a page with error: "Error instantiating web-application" , "Application: JSFIntro-view-webapp has been stopped".
JDeveloper I am using is: version 10.1.3.1.0.
I also tried with MS-IEXPLORE (changing the Preferences) with the same result (different look though).
I am saving the log in a txt file I could send to you if needed.
Thanks in advance.

Hi Roberto,
The jsfintro obe is working fine for me and most of the people who tested it.
I've seen the "Error instantiating web-application" when I usually deploy to a
Standalone OC4J being run on older JDK version than my JDev 10.1.3.1 (JDK 1.5)
Yet, I don't think you are deploying the jsfintro application.
Check where you installed JDeveloper: it is recommended to have it under
a folder name without any space. eg: C:\jdev10131
Check to see if you can run any other application :
eg: in JDev, Help menu -> Cue Cards -> Learn about J2EE applications ...
you should find some simple JSF ones.
if that still doesn't work, try downloading JDevStudio version 10.1.3.2, then
decompress it under your C:\jdev10132 folder, then run jdeveloper.exe.
Hopefully, this will run fine.
