You should look into the code of the RPCRouterServlet and see the chain of
calls being made to introspect the call envelope. I think the code to
introspect the header is in the RPCRouter class. Look into that and you
should be able to figure out how to extract the necessary values. The
RPCJavaProvider (if ure using the default provider) should also give you
pointers.

Subject: Re: using soap with tomcat 4.0b6 filter support
Hi Kartheek,
I already tried that. Unfortunately, the getHeader method on
HttpServletRequest returns an HTTP header which is different from the
SOAP headers that are inserted on the client side. The problem is that a
ServletRequest object has no notion of the structure of the data that is
contained in the request. Therefore it has no way of distinguishing
between a SOAP message or a regular XML message.
