[Mulgara-general] RMI port conflict

This process is wrong, since you only told Mulgara not to start an RMI  
server.  You also needed to tell Mulgara which port it should find the  
new server.

Unfortunately, even if you do it right, it looks like the server still  
won't work.  I just tried it now, and it complains that it can't find  
a _Stub class for the session factory.  This has come about because  
RMI no longer generates _Skel and _Stub classes by default in Java 5.   
Anyway, it looks broken for the moment.  I'm looking into it now, and  
will let you know as soon as I have something for you.
