Yes, it's against restrictions, but I think it's not possible, 'cause JSP
engines will treat the given path relatively to the application context.
That was the reason that I started the discussion. Cocoon source resolver
allows external paths, so if you specify a path like '/jsp/file.jsp' then it
will be resolved to a path outside of the app context (for Windows it will
be something like 'file:/jsp/file.jsp').

The 'file:/' prefix can be removed and JSP engine will get a relative to
context path.

When you use 'context://' protocol then path resolves to absolute path and
in this case you'll need to remove the absolute path to context to get a
relative path.

I think that it's a little hacky way. Just thoughts...
