transforming bytes to SOAP Message
Hello, I hope someone can help.
We're sending SOAP messages to our web service via a simple proxy. the
proxy sets up input and output streams and passes with SOAP message on to
the web service with no problems. Now what we want to do is add fields to
the body of the SOAP message when it passes through the proxy.
I suppose an ideal way to do this would be to transform the bytes stream
back to a SOAP message and manipulate the body, before passing it on. does
anyone know how to do this? The main problem is that the proxy is not in a
J2EE container so we can't use HTTPRequest.
Ideally I don't want to have to do string manipulation on the input and
repopulate a new envelope, if I can help it.
I'd be grateful of any help.
cheers
Duncan

hi Scott,
thanks for that. it was pretty much the conclusion I was coming too - I
just didn't know if there might be a way to re-use the SOAP envelope
rather than parse the message and create a new one?

Re: transforming bytes to SOAP Message
If the fields you add will depend on the contents of the SOAP envelope
being passed through the proxy, you pretty definitely will want to parse
the envelope into something, then create a new envelope to pass through.
You could do this with a standard XML parser. Creating and traversing the
DOM to see what you have received is not too onerous; likewise for
subsequently adding elements and serializing the modified DOM to a stream.
If you are always going to add the same fields, you might try to cheat and
not do full parsing, but I would guess that in the long run, you would be
better off using a parser and manipulating a DOM.

Right. Maybe you could have your app import some of api's used by soap
servers to package and parse soap messages.

Hi Mark,
thanks for this - unfortunately the proxy has to be a stand-alone app
sitting on a gateway machine, and definitely can't be on a server...

RE: transforming bytes to SOAP Message
Hi,
The problem seems to be that the proxy doesn't give you access to the apis
that you need to manipulate the soap message. It might be easier to rewrite
the proxy and have it live on a soap-enabled server.

Mark
