[antlr-interest] Re: ASTFrame

[rigpa_man]

Welcom David,

I had the same problem and finally figured out that the CLASSPATH 
wasn't set right. Don't forget to add a reference to your current 
directory as a single dot ('.') in CLASSPATH. If you don't want to 
touch CLASSPATH, you can do it on the java command line. I think you 
add "-d ." to the command line. I'm not a java programmer so this was 
a tough one for me.

Good luck,

Mark
