[antlr-interest] Getting error message: Cannot launcht the debuggerTab.

[roger_alexander at selinc.com]

Hi,

I just downloaded and installed ANTLRWorks version 1.4.3 with no problem. 
I'm completly new to ANTLRWorks so I thought that I would start with the 
expression evaluator tutorial [1]. So I downloaded the example grammar [2] 
and opened it in AW (running on Ubuntu 10.10). I then proceeded to follow 
the directions given in the tutorial; but when I tried to execute the 
debugger, I received the following error message:

        Cannot launch the debuggerTab. 
        Timeout waiting to connect to the remote parser.

I Google'd around look for others with similar problems and discovered a 
few from 2009 and 2010. However, none of those had a resolution or work 
around. I tried increasing the time out value as one of the posts 
suggested, but that made no difference. I'm stumped at this point and have 
no idea what to try next. Any suggestions would be greatly appreciated.

Thanks,

Roger Alexander.
