According to:
http://wiki.glassfish.java.net/Wiki.jsp?page=gfv3-appclientcontainer-onepager
It appears that applcient supports something like this (Taken From that web page); which may help (I'm uncertain and haven't done it):
-targetserver host[:port][,host[:port]...]
where host[:port] indicates the server host and ORB port to use during ORB bootstrapping. If the user omits the port then the ACC uses the default ORB port of 3700.
Values for -targetserver from the command line override those in the ORB-related
system properties or in the <target-server> element(s) in the sun-acc.xml configuration.
