For maximum portability, using getRealPath() is problematic -- you will
always get a null back if your webapp is running out of a WAR file
directly. Use ServletContext.getResource() or
ServletContext.getResourceAsStream() instead.

I think you have identified a very real problem, and am exploring ways
that Struts could be extended to deal with it. Do you think that putting
i18n-sensitive support into <forward> is all we need, or do we need to
think about <action> mapping that is i18n-sensitive as well?
