[antlr-interest] error messages

[William Lam]

Hi all,

I have a grammar file with rules such as

rule : "order" "by" literal ( COMMA literal)*;

The issue is that when i have invalid input such as 'ORDER BY',
i get an exception with the message "unexpected token: null"

Is there any way to get better error messages?  such as
'error near ORDER BY'?

I was looking through the exception handling document in the antlr 
web site.  Is it expected that I put an Exception catch block at the
end of each rule?
