I thought it should be as easy as specifying a property somewhere, but it appears that no such place exists. It even looks like Eclipse runs JBoss AS via a java command that it generates, rather than relying on the run.bat file, so it is not like you could edit the run file. Found it! Look in workspace\.metadata\.plugins\org.eclipse.debug.core\.launches\XXX.launch, where XXX is the name you gave to the server. Edit this entry: <stringAttribute key="org.eclipse.jdt.launching.PROGRAM_ARGUMENTS" value="--configuration=admin -b localhost"/> | Perhaps you should ask about this in the JBoss Tools (Users) forum; being able to provide additional command line arguments sounds like a worthwhile new feature request to me.
