I am looking a tutorial or step wise document that explains how to create and configure UDDI 3 to resolve SAP and SQL endpoints in BizTalk ESB solution.
My scenario is i need to send a request to SAP and receive response dynamically based on Content message type.
Thanks
HOLD ON! Do not even try to use UDDI.
UDDI has been deprecated in the BizTalk Product and beyond that, no one, literally, every used it. No one, ever.
For Sql adapter, you can refer to post at http://geekswithblogs.net/paulp/archive/2011/09/28/147087.aspx
Once you have SQL adapter working with STATIC resolver, simply use resolver connection string from itinerary XML to populate same key value pairs in UDDI. Next test resolver on designer surface to ensure that you are getting same name value pairs. Yes, UDDI 3 is unfortunately deprecated, so you may consider either BRE or implement SQL resolver.

I am new to BizTalk development. I have an existing SOAP web service, which has around 50 different operations. I want to connect this service to another application, but use the BizTalk server as an intermediary in this communication. So service and application should not know each other directly, BizTalk should be able to log all messages going through etc etc.
What is the best approach to make this work in BizTalk Server 2013?
So far I tried to create a new BizTalk Application and import the SOAP web service there. Then however it seems that I need to create around 50 different orchestrations, each one just mapping the incoming message in BizTalk to the external service for each service operation. This seems very cumbersome. Also publishing all those orchestrations becomes painful, as BizTalk cannot merge those into a single endpoint again. Ideally I would like to publish a single endpoint for BizTalk server on IIS that is using the exact same WSDL as the target SOAP service, ideally without having to create any orchestrations at all. Is this possible?
Thanks!
So, yes, but...what you want is absolutely doable but there would be lots of answers for that. Once you learn how things in BizTalk are actually working, it's obvious how to do this.
For example, a single Receive Location (IIS endpoint) can receive any number of request types provided they are the same protocol/format, SOAP, REST/JSON for example. The only difference in the IIS site is any metadata, so just don't publish that. The Message differentiation is done in the Pipelines just like any other BizTalk Message.
You don't really need Orchestrations for Maps, you can apply those at the Port Level provided it's a 1-1 relationship between the SOAP call and Map.
Please try a few things. I'll become clear. You can always come back for any specific issues.
I am struggling to transfer my data in my itinerary in my Biztalk ESB solution, I'm using Message-based instead of Orchestration. My itinerary scenario in Biztalk ESB is:
Receive request CreatePayment with 2 parameters: Claim Object and
Payment Object
Send Claim Object to external service to Verify Claim
Receive result from step 2, then combine the result with Payment Object in request at step 1, then send it to external service to Create Task
My problem is at step 3, I don't know how to combine data from 2 resources. Is there any knowledge that I missing in Biztalk ESB. I just started learning Biztalk for a few weeks. Now I got trouble and I really wait for feedback from you.
Sorry I have to post my itinerary picture to OneDrive since I cannot post it to this: https://onedrive.live.com/redir?resid=584F1A7DD6FCBF77!961&authkey=!ANQVuaTflyExPTo&v=3&ithint=photo%2cPNG
If you can switch to Orchestration, then setting some unique fields as correlationId will solve your problem.
If you are limited to use Message-based instead of Orchestration. below is 2 possible approach you may try.
If you can control the external service, change it to accept your payment object and return it as-is in its response.
If you cannot change the external service, what you can do is wrap the service such as an external assembly. then call this service in a mapping using script functoid.
Your problem seems like that of an Enrichment Scenario.
Check out the sample provided in ESB Toolkit samples:
https://learn.microsoft.com/en-us/biztalk/esb-toolkit/installing-and-running-the-message-enrichment-sample
You will have to use an Orchestration extender in your itinerary.
I'm a bit confused on what the biztalk wcf publishing wizard produces?
So for example, I have a simple biztalk project that takes a Input xml file, maps it, and outputs to another folder.
Can i use the wcf publishing wizard to create a webservice to pass in and out an xml to the solution?
Yes you can. WCF Publishing wizard is for this purpose. You can either expose your schema as a service or your Orchestration. It has few options to choose e.g. whether you want to use BasicHttpBinding, WSHttpBinding or custom. You should have a local IIS configured for this. It will also create a receive location in BizTalk to receive the message from IIS service and return the response.
More details about it can be found on http://msdn.microsoft.com/en-us/library/bb226547.aspx
To answer your specific question, yes, you would 'publish' the schemas.
To note, there is no difference in the output of either option. Publishing an Orchestration merely reads some metadata from the compiled Assembly. If you set the same values when publishing 'Schema', the output metadata will be the same.
Also note, the IIS endpoint is completely schema agnostic, meaning it makes no attempt to validate the messages it receives or sends, regardless of what Schemas or Orchestration Port you 'publish'.
If I need to build a specialized web app to be able to terminate messages processed by specific send ports, WMI is one option. Are there others? and are there pros/cons to each approach?
You should be able to terminate messages programmatically by referencing the Microsoft.BizTalk.Operations.dll assembly. That will allow you to use the TerminateInstance method of the BizTalkOperations Class, which allows you to reference a remote BizTalk instance (using this constructor) without enabling remote WMI administrative access.
You may also need to reference Microsoft.BizTalk.Pipeline.dll in Visual Studio to get IntelliSense to work.
The BizTalk SDK includes a sample app that you can review, as well, to see how to look up a message instance, which you'll need for the parameter to the TerminateInstance method:
http://msdn.microsoft.com/en-us/library/gg163868
For example:
BizTalkOperations _operations = new BizTalkOperations()
IEnumerable messages = _operations.GetMessages();
foreach (BizTalkMessage msg in messages)
…
Have you considered the "/null" Send Port Adapter? This allows you to send messages to a "null" port, where they effectively disappear. Source code can be found here, although it hasn't been updated since BizTalk 2006 R2.
If this isn't relevant to what you are trying to achieve, maybe some additional information regarding the use case would help.
Using the BizTalk ESB Toolkit 2.0
We are working on a project where we need to call a proxy to a web service which is a DLL. We have no problems doing this via an orchestration since you can use a static port and configure it to use the SOAP adapter with the web service setting pointing at the assembly in the BizTalk Admin interface. In the itinerary though there doesn't seem to be an obvious way to do this since dynamic ports don't have the option to use the SOAP adapter.
There is a good reason why we want to do this, don't worry.
Following on from this, we implemented a custom adaptor provider but are having problems getting it to work.
We followed an (old) example shown here:
The custom adaptor provider inherits from BaseAdapterProvider and overrides the SetEndPoint(Dictionary, IBaseMessageContext) method.
The method extracts the assembly name, type name, and method name that are passed in via the resolver dictionary and then writes them to the pipeline context:
pipelineContext.Write("TypeName",
"http://schemas.microsoft.com/BizTalk/2003/soap-properties", typeName);
pipelineContext.Write("MethodName",
"http://schemas.microsoft.com/BizTalk/2003/soap-properties", action);
pipelineContext.Write("AssemblyName",
"http://schemas.microsoft.com/BizTalk/2003/soap-properties", assembly);
and sets the transport type to soap:
pipelineContext.Write("TransportType",
"http://schemas.microsoft.biztalk.practices.esb.com/itinerary", "SOAP");
In all other respects the adapter provider is nearly identical to the example shown in the link above, except for the obvious change from SMTP to SOAP.
The adapter provider assembly is signed, GACed, and added to the esb.config.
The adapter provider is called from an itinerary that only calls the service and then returns the response. We are testing the itinerary from the Itinerary Test Client that is shipped with the toolkit. Event logging within the custom adapter shows that the adapter code is being called. The problem is that the message is not being routed to the service proxy. The event viewer gives the following error:
The Messaging engine failed to process
a message submitted by adapter:SOAP
Source
URL:/ESB.ItineraryServices.Response/ProcessItinerary.asmx.
Details:The published message could
not be routed because no subscribers
were found. This error occurs if the
subscribing orchestration or send port
has not been enlisted, or if some of
the message properties necessary for
subscription evaluation have not been
promoted. Please use the Biztalk
Administration console to troubleshoot
this failure.
Investigating the suspended service instamces in Group Overview shows two things:
The values for assembly name, type name, and method name are being set correctly.
The message body is missing.
We have tried configuring the send and receive pipelines on the send port to be both XMLTransmit/XMLReceive and ItinerarySendPassthrough/PassthroughReceive and it makes no difference.
Is there something obvious we might have missed? Do you have to explicitly pass the message body through? If so how?
EDIT:
Following a request from the BizTalk ESB Toolkit forum I am posting screen shots of the itinerary, context and send port filters.

Many thanks, Nigel.
first of all I'll say you are trying to over engineer the solution. Adapter development is not trivial and there are various things you need to take in to consideration. Developing and Deploying adapters are categorized as platform changes, which effects your whole environment, so if you are not familiar then your shouldn't do it. I would recommend you taking some other route. At this point I personally don't have enough insight into ESB internals, so won't be able to comment on it. At worst case you may be better off using the .NET proxy dll directly inside your orchestration (expression or message shape) rather than building an adapter. Even though its not recommended approach, still I feel its better than custom adapter approach.
Semantically, I don't see why a solution that involves a WCF-BasicHtpp adapter would not work in your scenario. In any case, I would definitely try to see what happens with a WCF-BasicHttp adapter, and once I got a working solution, I would switch to a custom SOAP adapter if that is really necessary.
Currently, your solution is weird - in the sense that you have an On-Ramp directly connected to an Off-Ramp. I've never seen that in any of my itineraries. You might need to create an intermediate messaging or orchestration Itinerary service in betweeen.
Otherwise, the message effectively gets published to the message box and obviously there is no subscribers for it, hence the error you encounter.
