hello

thanks for your post, but can you tell me about the DomainObject and go more through the code of the ProcessMessage

Interesting post. Did you ever find out why the object was coming through as NULL? Did it have something to do with the"Wrapping"? I had a similar problem when I was migrating a regular ASP.NET service to one hosted in Biztalk. The WSDL seemed fine and the calls came through but I had accidentally left the Biztalk option to "wrap" the messages (because BTS deals with multi-part message so wrapping is the default) and so i was getting nulls. Changing it to unwrapped worked fine.

Cheers

Hi again dbam987,

I had a bit of time to try re-writing some of this code and cleaned it up a little. In my implementation, I haven't had any problems with the XML directives as they all get escaped/encoded so it all goes through. I am able to accept a document with XML directives and write out to disk without issue.

If you mail me directly at glav@aspalliance.comREMOVETHISBIT then I'll send it your way to test it.

Hi Glav, thanks in advance for taking a look. I think I'm on to something to resolve this. What I'm thinking is to write a custom message encoder that will encode the incoming data into what I can use. See the following link for what I'm following: msdn2.microsoft.com/.../ms751486.aspx

However, I can't shake the feeling that there is an easier way...

Hi dbam987,

As soon as I get time I'll have a bit of a play with it. Encoding the payload before sending is kinda defeating the purpose as it forces the client to change and this approach is ideally to NOT have the client change at all.

again, as soon as I get some time, I will have a look. At a guess, you'll probably have to use one of the GetBody derivatives and some funky casting :-)

My mistake. I meant to say that the XML document that is in the message body part contains XML directives which cause the parsing of that section to fail because its not expecting them there. Is there a way around that? Or will the payload have to be encoded before hand?

I have a slight "gotchya" that I'm still trying to work around. What if the incoming message's body is an XML document that has directives in it, such as <?test?>? Creating the buffered copy causes an exception because it assumes the body is valid XML. Any way around this one?
