How to return HTTP 204 on Document perform()?

[Bryan Field-Elliot]

I've implemented a message style handler (server) in Axis 1.0, using the following method signature style:   Document perform(Document in)   In some cases I need to return HTTP 204 (OK) with no message body. I had hoped that returning "null" from this function would achieve this result, but it doesn't (instead, it returns an empty message body).   Can someone please advise the right way to do this?   Thank you,   Bryan
