Subject RE: [HELP] problem using antlr in ant
Date Mon, 15 Dec 2008 07:29:46 GMT
HI Sunil,
 I was able to resolve the error. The problem as indicated because of
classpath issue itself. Now I am able to build grammar file using antlr
target inside ant.

Regards
Bharath

It's been a while since I've worked on this, so I'm afraid I won't be
able to give you much precise help. Make sure you have the required
antlr jar files in your ant installation, the task AFAIK should work
correctly from there on.
