[wildfly-dev] Change CLI to Default to Remoting

Tue Aug 6 06:09:31 EDT 2013

Access control has taken priority at the moment but I will see if I can 
get a change to put something together to summarize a set of rules for 
determining exactly how to connect.

Recently issues have also been identified for connections from jconsole, 
they are not directly related but do show another client affected.

One aspect of this discussion was how the configuration in jboss-cli.xml 
can be used / expanded on to determine how to connect - I wonder if we 
could make use of a single management client configuration that could be 
used by all management clients when making connection decisions rather 
than just the CLI - e.g. wildfly-management.xml

Regards,
Darran Lofthouse.
