Where do I put static files for GWT app? war folder or public folder?

I have some JavaScript files, a main HTML file, a main CSS file, and some CSS files that get imported into the main one.

I understand that I can put static files in two places: a) the 'war' folder; or b) the 'public' folder.

Where is the best place to put my static files? Are the two locations treated differently? Is there a 'best practice' on this issue?
