I have two Orchestrations (Parent & Child), there is a variable existed in my Parent Orchestration and my Question is that I want to access that variable in my Child Orchestration, for your information I'm using Direct Binding Partner Orchestrations.
NOTE: I Don't want to use Call or Start Orchestrations Shape, Somehow i have to implement this with
Direct Binding Partner Orchestrations.
How would you do this?
Add a new field to the XML message that you are publishing via the direct bound port and assign the value of the variable to that field in the XML message.

I need to read Websphere queue name from my orchestration. The queue is configured with MQSC transport.
Can anyone supply a code example for accessing some MQ properties of incoming message? Do I need to reference a special DLL for this or is it available out-of-the-box?
If you have installed the adapter all then you will be able to access the
MQSeries Context Properties and don't need to specifically reference the DLL.
For the queue name you will probably want the MQXQH_RemoteQName context property.
To use the property in an BizTalk shape (expression, decision) you would have something like
Message_Name(MQSeries.MQXQH_RemoteQName)
Where Message_Name is the name of your message in the Orchestration.
I am currently writing an orchestration that is directly bound to the message box, picks up messages and filters according to the filter expression in the receive shape inside said orchestration. The problem I'm having is this; I want to be able to change the filter in the BizTalk bindings, just like send filters are changed in the bindings. Really, I just don't want to have to recompile and re deploy every time My filter changes. Is there a way to do this? I'm thinking maybe modify the binding.xml file somehow, or possibly try a custom pipeline with configurable properties(as my last resort).
If it matters I typically use the BizTalk Deployment Framework for deployments.
No, it is not possible to modify a Receive Shape Filter at Runtime.
If the filter needs to be dynamic, then you will have to apply that logic upstream. The idea of using a custom Pipeline Component is a common solution.
One other approach to consider is leaving you Receive Shape Filter broad and testing each incoming message with the BRE. If it 'passes', continue processing, otherwise exit. BRE Policies/Rules can be updated at runtime.
For this sort of thing you will probably want to execute Business Rules in the Receive Pipeline that then sets a context property on the message that then determines the routing.
That way the filter in the Orchestration is lightweight and doesn't need to be changed.

I have an "enevelope" schema and a body schema and I have setup the correct properties on the "envelope" to point to the body.
I also have a property schema for promoting a value in the body message so that i can route on it.
I set up a File drop receive location and two send ports. Each send port subscribing on a different value of the promoted property. The receive location uses XmlReceive and the send ports both use XmlTransmit.
When i drop one envelope message at the Rcv location, Bts picks it up, splits it, promotes the property and my send ports pick up the relevant messages and do their thing.
File drop was fine for testing, but the real scenario is slightly different.
I want clients to submit "envelope" schemas containing multiple document elements via Wcf
So i published the envelope schema as a Wcf endpoint using the publishing wizard. Let it create the new Receive location. Wired up a Wcf client to talk to this endpoint and submitted a message.
Without changing anything on the Send ports in BizTalk I expected the same result;
However I now get a routing failure.
If i remove the extra filter in the Send port that filters on the promoted property it works, no routing failure.
So ... it would appear that the promoting of my property is not happening on the Wcf receive location.
I have checked; the Wcf receive location is using XmlReceive.
What gives?
How do i fix this?
I would guess that the namespace of your incoming message has changed as a result of changing it to use WCF.
This can cause the property promotion to no longer match the incoming message.
You can view the property promotions in the tracked messages in the BizTalk server admin tools.
I have a problem with WCF seemingly not including attributes such as Category when passing entities around.
I have a class wrapped around an EF entity, used to populate a property grid on a thick client.
I am trying to retrieve information from the server, using WCF, and to replicate the property grid on the client side. I have tested the code, and in the host, I am able to determine the category of the elements in the instance.
When I request an instance from an ASP.NET site, however, it seems that I cannot retrieve the category information. All I get is, Misc, so I assume that means when I serialize it, the attributes get stripped.
Information specific to .NET is not passed in metadata. Therefore, the information is not used in creating the proxy classes that you create using svcutil or "Add Service Reference". This is why attributes, or non-default constructors, or methods, or indexers, do not appear in proxy classes.
You should try to do without this sort of information. However, if you really need it, you can put those types into a separate assembly, and share it with the client. This will mean that you have to update all of your clients when you update that assembly.
How can I call a BizTalk Orchestration dynamically knowing the Orchestration name?
The call Orchestration shapes need to know the name and parameters of Orchestrations at design time. I've tried using 'call' XLang keyword but it also required Orchestration name as Design Time like in expression shape, we can write as
call BizTalkApplication1.Orchestration1(param1,param2);
I'm looking for some way to specify calling orchestration name, coming from the incoming message or from SSO config store.
EDIT: I'musing BizTalk 2006 R1 (ESB Guidance is for R2 and I didn't get how it could solve my problem)
The way I've accomplished something similar in the past is by using direct binding ports in the orchestrations and letting the MsgBox do the dirty work for me. Basically, it goes something like this:
Make the callable orchestrations use a direct-bound port attached to your activating receive shape.
Set up a filter expression on your activating receive shape with a custom context-based property and set it equal to a value that uniquely identifies the orchestration (such as the orchestration name or whatever)
In the calling orchestration, create the message you'll want to use to fire the new orchestration. In that message, set your custom context property to the value that matches the filter used in the specific orchestration you want to fire.
Send the message through a direct-bound send port so that it gets sent to the MsgBox directly and the Pub/Sub mechanisms in BizTalk will take care of the rest.
One thing to watch out in step 4: To have this work correctly, you will need to create a new Correlation Set type that includes your custom context property, and then make sure that the direct-bound send port "follows" the correlation set on the send. Otherwise, the custom property will only be written (and not promoted) to the msg context and the routing will fail.
Hope this helps!
