Re: Adapt the scripts that register the custom theme and skins

I've run into problems using war: for skins. While they are served from the war, they are aggresively cached and cannot be updated until a server restart. I used res: for the skins and they worked as I would expect. war: still works fine for the theme and layout templates.

See this article - http://www-10.lotus.com/ldd/portalwiki.nsf/dx/Deploying_and_developing_IBM_WebSphere_Portal_8_themes_A_step-by-step_guide

It's for 8, but the principles for the deployment script are the same.
