[antlr-interest] Regardig time out

[Jim Idle]

Well the first thing I get is:

[15:59:05] error(201): t.g:4:5: The following alternatives can never be matched: 3

This is because your parser rule does not make sense. It should be:

simplerule : CHAR* EOF ;

However, that token makes more sense to be called WORD to be honest. IF you cannot launch the debugger after that, then there is something wrong with your setup. As I say below, you should start ANTLRWorks from a command line console and see what it tells you when you try to start the debugger. Do you have firewalls for instance.
