Does any of you understand what weblogic.socket.Muxer is used for in WebLogic 8.1?

We have ported an EJB application from BEA Weblogic 8.1 to Glassfish 2.1. The client is accessing the server through RMI, no web client.

How can I get the same behavior as with Weblogic? Glassfish 2.1 logs via java.util.logging. Logging content, by default, is collected in [Glassfish root]/domains/[domain name]/logs/server.log For configuring j.u.l, find the logging.properties file in the JRE that is used
