There are many non-lex/yacc scanner/parser generators available for Java,
but if you want a quick port, I'd stick with what you have.


I've used BYACC/J http://troi.lincom-asg.com/~rjamison/byacc/ with success.
It is Berkeley YACC that outputs Java code. I don't know of Bison port, but
it shouldn't matter much unless your code is married to one of the Bison
extensions.


For lex, there is jflex http://www.jflex.de/. I haven't tried it. It is
_not_ flex, but apparently it is reasonably close, and there is a section in
the documentation on porting from lex/flex to jflex.
