First, I just want to say that warbler is fantastic - thanks for all your work.
Unfortunately, I've been having a problem with running a compiled rails war on both Tomcat and Jetty. It's a Rails 3.2.11 app, and I've precompiled all assets and packed all gems into vendors.
Running bundle exec warble war produces a working war file, and it runs well on both Tomcat and Jetty.
bundle exec warble war
Running bundle exec warble compiled war produces a war file, but the 404 page is delivered for everything except for assets.
bundle exec warble compiled war
I am using warbler 1.3.6.
If you need any more information I'm happy to supply it.
I can confirm that this also happens when creating an executable war file, with bundle exec warble compiled executable war. A standard executable war works without a problem.

Are you using devise?
If so, I expect that you are getting this issue plataformatec/devise#2208
