Well this is a quick and probably non-working workaround. The correct  
way is to initialize Plexus in XMLRPC mode too. Right now it's  
initialized in Servlet mode only I think.

For example if you need to do any velocity stuff (which is the case in  
the XMLRPC API I believe when retrieving a page's rendered content) it  
won't work since Velocity rendering is now done in a component.

I guess I'll have to look into this to do a proper Plexus  
initialization in XMLRPC mode.
