The only way to 'publish' messages to a receive port is through an adapter,
remember? To enable your server application to submit to a receive port, it
has to use any of the available transports (SOAP, HTTP, ... or your custom
one).

Please open up VS.NET after installing BTS2004. You will find the biztalk
explorer inthere. Create a new send port. Among its properties you will
find a "filter". This is the subscription I'm talking about.

Most of the scenarios never ever need dynamic subscriptions. If you want
applications to "dynamically subscribe" to messages, you will need to dive
into the BizTalk Server WMI stuff. This allows to create subscriptions 'on
the fly', although I'm not sure whether that's a good design decission!
Send ports certainly weren't made with that kind of scenario in mind. They
are typically created at deploy time, rather then 'on demand'.

How is this
