[antlr-interest] AST generation: EXPRESSION TREE example.

[Bharath Sundararaman]

Hi Monty,

Yes, they do. In fact, if I don't use INTNode, PLUSNode and MULTNode in my
grammar and just use CalcAST in my "main" class which runs the parser and
the lex, it works fine. I can correctly resolve CalcAST and use it. Should I
qualify my usage of INTNode, PLUSNode and MULTNode? In my tokens section, I
have the line "PLUS<AST = PLUSNode>;". Also, all my class files exist under
one same package.

Thanks again,

Bharath.

Do you have "package myPkg;" in your CalcAST classes?  Your error is 
about java not being able to load the class properly because it can't 
find it.
