I've pretty much have done what the wiki of myfaces suggested
http://wiki.apache.org/myfaces/Websphere_Installation
But here's what I still get:

Funny enough, the JSF Application itself is being run correctly. The automatic workflow with JSFUnit still fails.
Here's some other bits of the log file regarding myfaces init.. when running the app to start the jsfunit automation

The libraries are - as suggested on the wiki - all in the appname\web-inf\lib directory. The "parent_last" parameter is set, and the faces xml files are edited so they now have version 1.1 information in them to not request internet.
I'll try to set up myfaces as shared lib now...
