seam-gen changed the source paths for the action and model directories as follows:

src/action -> src/hot
src/model -> src/main

The purpose of this renaming was to reflect how the two sourcepaths are compiled and not by which types of components and classes they might originally contain. Internally, we will still refer to src/hot as the action directory and src/main as the model directory, but it opens up the possibility of the user adding non-hot deployable components to src/main without feeling a semantic mismatch.
