I'm really not sure what the problem might be, since I've never 
experienced this symptom, myself.

In my (limited) experience, all that is required is that you give 
the "-debug" option to ANTLR when you build your parser from your 
grammer. Then, when you invoke that parser, it will wait for a 
connection from the debugger on the usual port (I don't know, offhand, 
how to alter the default, 49153).

There is one thing: While the parser seems to have an unlimited timeout 
(which is to say, I've never encountered a timeout), ANTLRWorks most 
certainly _does_ have a timeout (configurable via the "Debug" tab of 
the preferences dialog—if I recall, the default is 10 seconds), so if 
you issue the "Debug remote..." command and wait longer than its 
timeout before launching the parser, it will give up and alert you that 
it failed to connect.
