This should be "Index.vm"
Actions don't have a suffix since they map to Java code. Pages do since they
map to template pages.

That is the wrong way to use the Log class that comes with Turbine unless
that is your own logging class or something (I don't see your import
statements).

Weird. That works fine for me. Does the log message underneath show up?

Right. You don't want to override the Screen that gets executed. :-) Page ==
Template.

All setPage does is define the URI.

Your URI example above should generate:
http://localhost:8080/foo/servlet/foo/template/Index.vm/action/LaunchApp?jse
rvsessionid=laksjdfljasldffdljk

Nope. I think you are just confusing yourself. :-)
