font-family:Arial'>I have been getting on fine learning ANTLR. I have written
my grammars and executed the examples downloaded from “The Definitive
ANTLR Reference”. All grammars work fine from the command line, and most
work fine from ANTLRWorks. The only problem is that whenever I separate the
tree grammar and parser grammar I get the modal error window in ANTLRWorks
titled “Connection Errror”, and stating “Cannot launch the
debugger. Time-out waiting to connect to the remote parser.”<o:p></o:p></span></font></p>
