I'll look into the assembly package, but I'll use merlin if I can get it
working.

Any sample code for running Merlin in Tomcat?

I'm trying to run merlin in a standalone tomcat engine. Not sure what
more you want for the scenario.
To try and get things going I copied much of the bootstrap.Merlin code
but instead of grabbing the properties from a file I construct them from
the servlet config. I've been trying to get the demo to work, but have
had a few problems. Most I think I've got straightened out. I'm still
getting the following error, though:
Message: Controller deployment failure.

Any ideas what's causing this? Is this a problem with the classloader
setup or something, you think? Again, sample code for running Merlin in
Tomcat would be much appreciated.

Thanks again.
