Blogging Roller

I've been trying to figure out why Mozblog will not work with Roller's Blogger API implementation. I haven't had much luck, but I have again come across an irritating little issue with the Servlet API request.getRequestURL() method. I'm calling on the blog support line for advice.

Tomcat/Servlet experts, what do you make of this comment from Roller's RollerContext.getContextUrl() method?

 // If you are running Roller behind a foreground server, 
 // then your Servlet engine may be operating on a different
 // port than your forground server. For example, I run Roller 
 // on a Tomcat background server that operates behind an 
 // Apache foreground server. My Apache server is on port 80, 
 // but my Tomcat server is on port 1003.
 //
 // If this is the case, then request.getRequestURL() may 
 // return a URL that is valid but that includes an unsightly
 // and unnecessary port number that you would rather not 
 // include in weblog permalink. In other cases (e.g. you are 
 // running a standalone Tomcat instance on port 8080) the port 
 // number is essential.
 //
 // To deal with this the Roller getContextUrl() method uses 
 // a configuration parameter to determine if it should include 
 // a port number. It calls request.getRequestURL(), parses apart 
 // the result, and builds a context URL suitable for use in a 
 // permalink with or without a port number.
