Use the FAQ luke ;)

This entry is about C++ mode though. But the idea for javamode is the same.

Caveats for some handmade AST's you'll have to manually set the line/file
info. But having a custom ast type with an initialize func that grabs the
info from a token you'll have most of the generated ast's covered. There
are more discussions on this topic in the mail archives. (maybe on the
forums as well)

Cheers,
