look at the run.bat in the bin dir. There is a commented out line that sets the jpda options.
Change run.sh(run.bat) to include in the debug options
in the java command.
./run.sh -c all
to start the "all" configuration.
In run.bat uncomment the line that adds the debug params to the call to the JVM. As far as starting several servers, just CD into bin and type run -c default, run -c all, run -c minimal. And thats after you change configuration of port settings, so they don't all try and use same port. Not sure how to do that.
