I am trying to send a synchronous MDN via AS2 and also bind that port to an orchestration. Is that possible? I tried the following link with no luck:

Update:
You don't need to bind the port to the Orchestration, you can always put a filter expression in the Receive Shape of the Orchestration, and you can make it a one way Logical Port in the Orchestration, so you don't send out two responses.

I need to submit something to a web service, then I need to send something over MLLP using the HL7 MLLP adaptor and the message needs to contain something returned by the service, and something that was sent to the service, and I'd like to use a pure messaging solution if possible, not an orchestration.
So basically I have two send ports. The second needs to subscribe to the response of the first, which means that it's message will the the first send ports response.
The trick is I also need some data from the first send ports request message. Is it possible to get that somehow?
The correct way to do this is use an Orchestration.
There is nothing wrong with using an Orchestration, and Orchestrations exist exactly for this purpose.
If someone is telling you Orchestrations are not right or you've read that somewhere...they're wrong. That's it. If you're having problems using Orchestrations...telling you straight up, you're doing it wrong.
In an Orchestration, you can probably use a Map to merge the content into the service response. Exactly the use case it's meant for.
Here's a started Suspend/Resume pattern: BizTalk Server: Suspend and Resume an Orchestration on Two Way Port Error
You have no control of this in a Messaging only solution.
Is it possible to expose a SOAP endpoint via BizTalk that calls another SOAP service without using orchestrations but just maps?
The current solution where orchestrations are being used is very slow (orchestration overhead is greater than 1,5 seconds) and performance gets even worse when it comes to high concurrency. I require a solution for low latency.
While not 100% sure for a SOAP endpoint, I have done this for WCF-BasicHttp, but cannot think of a reason why it would not be possible for SOAP. Various properties get promoted to the message context that would allow you to route a message to a send port, like the SOAP action, the receive port name, etc. Configuring a send port to subscribe to the relevant messages should be trivial. The mapping from the inbound-request to the outbound-request can happen on either the receive port or the send port.
In the case of using a solicit-response send port, the response message coming back would automatically be subscribed to by the originating receive port, assuming it is also two-way. Again, the mapping from the inbound-response to the outbound-response can happen on either the send port or the receive port.
The xml messages coming out of my send port do not reflect my orchestration used to transform the message.
Although I tested the message map and observed the expected transformation of XML, I am confused on how to test the orchestration that uses the map.
The orchestration has the following:
ReceiveMessage
ConstructMessage => Transform
SendMessage
After I deployed the Biztalk application and provided source messages to the instance, I observed that the messages coming off the send port still do not reflect the expected transformation. Instead, these messages have the same format as the source XML schema.
NOTE:
I am learning Biztalk.
I have stopped and restarted the server instance within the Administration Console.
If this is the first time you have tried this, it's probably because the Message isn't making trough the Orchestration because the Ports aren't Bound properly. Make sure the Deployed Orchestration is Bound to the right Receive Port and Send Port (and Host) and Enabled.
If you're using PassThruReceive then I suspect that you have some other filter set for your Send Port and that your Orchestration is not even instantiating. Try using the XmlReceive pipeline. This will run the XmlDissasembler mentioned above which will read the namespace and root node and publish the message to the message box.
I suspect that you are subscribing in your Orch by message type, in which case, will pick up the message. When this happens, if you get 2 messages output, then you do indeed have another filter on your send port.
I have to develop an orchestration which uses a start orchestration shape followed by send port.
Scenario: If a "Sendport4" failed to send the message, I don't have to execute "Starting Orchestration Shape".
But in my case, when "sendport4" is getting failed, It is calling "Start Orchestraton Shape".
To handle this schenario, I tried to put the exception handling, But didn't worked.
Can any one please help, what can do handle this?
Set Delivery Notification to Transmitted on the Send Port shape in the Orchestration.
I have the same problem as described here:
I am using two orchestrations. First orchestration calls the second using direct binding through a two-way send port. Second orchestrion has a two-way receive port to send the result back to the first. Every thing is working as it should but I am getting the following exception.
A response message for two-way receive port "Unknown " is being suspended as the messaging engine could not correlate the response to an existing request message. This usually happens when the host process has been recycled.
And the suggested solution works as well (set the BTS.EpmRRCorrelationToken value to a random value, new GUID in my case, in the first orchestration before send to the direct binding port and then in the secod orchestration i copy the value from the inputMessage to the outputMessage, so the value remains the same. With this method BizTalk knows how to correlate the response back to the caller). But I can't understand why this works and if this a good way to solve the problem. The BTS.EpmRRCorrelationToken flow is the following:
When I don't change the BTS.EpmRRCorrelationToken property, it is the same in all messages which flow in the process, but why on Earth doesn't BizTalk change it instead if it can't correctly correlate the messages?
Changing this property is certanly OK in your case.
The problem is direct binding. When you use it, you actually going more "low-level" way and have to deal with how BTS publish-subscribe mechanism works.
Send-Receive port subscribes to receive a message with a specific BTS.EpmRRCorrelationToken. So when you post receive message again in the Message box (for second orch), receive port grabs it too and unsubscribes then. When you finally try to send a response - there is noone waiting for it. So you have to change that property until you sending response back to the port.
