Hi people. <
I have to use antlr in java to generate a parse tree for a simple java-like grammar.
But while generating the tree, i have to ask for rules in my grammar and don't know how to do this.
For example if i want to choose an alternative for expanding a nonterminal symbol.

How can i do this in java?
Btw, i use eclpse.

Thx for answers,


Martin.
