So what would I have to do in order to make a "JSR-160" 
connection with MC4J (what I'm supposed to do).

Everything's working fine when using the MX4J 1.1 RMI 
connector (JRMP adaptor).

Cheers,
                 Michael

It looks like your creating a JSR-160 style adaptor and then
trying to connect the proprietary mx4j 1.1 rmi connector to
it. You want to select "JSR-160" from the connection type in
MC4J for this type of connection. 

(I suppose this is now misleading now that MX4J support
JSR-160 style service adaptors. I'll have to fix that.hu)
