Hi all

So, today my boss confirmed that I can go to the event held by the Swedish BizTalk User Group. See the details of the event here: http://bugs20100908-widget.eventbrite.com/. The event says it’s a BizTalk 2010 launch party… but whether BizTalk 2010 will be out there… I don’t know.

I am really looking forward to hearing what Richard Seroter, Ewan Fairweather and Stephen W. Thomas have to say. I have preordered their book, both paper and ebook editions. Hopefully I will receive at least one of them before September 8’th where the event starts.

Also, this will actually be the first time I will meet Johan Hedberg and Mikael Håkansson, who are two of my Swedish colleagues who are both BizTalk MVPs.

Anyway, flight and hotel are booked. Look for me there!

Hi all

Today I exported an MSI file from my development machine and wanted to import the MSI file on our test environment.

I got this error, though:

Change requests failed for some resources. (mscorlib)

Unable to process create change request for BizTalk binding "BindingInfo.xml". Import bindings (overwrite) failed. (Microsoft.BizTalk.ResourceManagers)

Failed to update binding information. (mscorlib)

Cannot update receive port "WcfReceivePort_FvmIndberetningCommon_CVR/FvmIndberetningCommon_CVR". (Microsoft.BizTalk.Deployment)

Cannot update receive location "WcfService_FvmIndberetningCommon_CVR/FvmIndberetningCommon_CVR". (Microsoft.BizTalk.Deployment)

The following items could not be matched up to hosts due to name and/or trust level mismatches:
Item: 'WcfService_FvmIndberetningCommon_CVR/FvmIndberetningCommon_CVR' Host: 'FVM_Indberetningsplatform_IsolatedHost' Trust level: 'Untrusted'
You must do one of the following:
1) Create hosts with these names and trust levels and try again
2) Re-export the MSI without the binding files and have a post import script apply a suitable binding file. (Microsoft.BizTalk.Deployment)

Now, the error message is pretty easy to understand. What had me baffled was, that the host exists and it IS untrusted. So there is no mismatch and the two ideas as to what to fix don’t seem to apply to my situation.

It turned out that the issue was that after creating the needed host and host instances, I had forgotten to add the necessary Receive Hander on the appropriate adapter for the receive location. But the error message doesn’t say anything about that – it just says that I need to create the host with the right trust level.

So, this post is just to let you know that there is another reason for the error message than what the error message states.

Hi all

I have decided to start up a personal blog as well. I get a few complaints from people who don’t care about my personal life, and therefore, I will be moving personal blog entries to my new blog at http://jan.eliasen.dk – with an RSS feed at http://jan.eliasen.dk/syndication.axd

This blog will NOT change! Well… personal blog entries will not appear anymore, but other than that, I will still be blogging about technological abnormalities, funny things, strange things, errors, and what not…

So, for Jan, the person, go see http://jan.eliasen.dk

Thanks

Hi all

The other day a developer who needs to call a BizTalk exposed web service approached me and told me that there was an error in the wsdl – something about the Response having the wrong fields.

So, I fixed it – I changed the XSD and ran the WCF Service Publishing Wizard again.

I called the developer and told him that everything was fine now. He refreshed his service reference and told me that everything was just as it was before. So I thought; Restart IIS.. and I did. Developer goes: Jan, what is wrong with you? Everything is still the same!

So now I actually need to start thinking…

Turns out, that silly I just did this:

1. Made my changes to the XSD
2. Recompiled
3. Run the Wizard
1. Point to the newly compiled assembly
2. Finish the wizard

BUT, what I forgot was to deploy the newly created assembly… or at least GAC it. Because the wizard, even though you point to a .DLL in the file system, will look for the assembly in the GAC with the same strong name and used that instead of the .DLL you chose. To me this is really silly… It could at least provide a warning that it will ignore the assembly I chose before ignoring it.

Anyway, after deploying the new assembly, everything worked just fine.

Hi all

If you read the documentation for Correlation Sets (here), you will see that it clearly states that:

“Each correlation set supports a maximum of three parameters.”

Now, the documentation for BizTalk 2010 is still subject to change, but you will find the same text in the documentation for previous versions.

The funny part is, that inside the Orchestration View, you are allowed to add as many properties to your Correlation Type as you please:

You will get no compiler error, as I would have expected, and no compiler warning, either.

I implemented a small orchestration that uses the Correlation Type seen above and it looks like this:

Basically, a message in, a transformation, an output and then a response back in. The “msg_FirstOut” initializes the correlation set and the “msg_SecondIn” follows it.

As mentioned, the compiler will not complain at all and I can deploy the solution. Once I send a message through, an instance subscription is created once the send shape has finished, and this surprisingly looks like this:

As you can see, ALL five properties are used in the instance subscription, which in effect means that the documentation is wrong.

So this brings me to the point; The documentation states, that you can only have three parameters (not sure why they call them parameters) in a Correlation Set, but this actually ONLY applies to Correlation Sets used in Convoys.

If I change my solution to utilize a parallel convoy like this:

or to be a sequential convoy like this:

then I still get no compiler warning or error no matter how many properties I have in my Correlation Type, but if I deploy the solution and try to start the orchestration, I get this error message:

“The maximum number of convoy set properties has been exceeded. A convoy set can only contain up to 3 properties.”

Now, you may very well ask, what is a convoy set? And yes, it is a bit confusing that the error message uses a term that is actually internal to BizTalk and not something your average BizTalk developer cares about. But a convoy set is simply a correlation set that is used in a convoy.

So this means, that for correlation sets that are used for convoys you can only have three properties, which actually comes from the fact that the table “ConvoySets” in the MessageBox database has three columns called “uidPropertyID1”, “uidPropertyID2”, and “uidPropertyID3” which contain GUIDs that are the GUIDs of the properties in the correlation set. So since only three fields exist in the database, only three properties can be in a convoy set.

So to me, it would nice if:

1. The documentation was clear about the fact that the limitation only applies to correlation sets used in convoys
2. The compiler would provide an error if you use more than three properties in a correlation set used in a convoy so you don’t ahve to wait until starting the orchestration to find that out.

Happy correlating and convoying out there!

Hi all

This is probably most useful to Danish BizTalk people… We are four guys trying to start up a Danish BizTalk User Group.

The first meeting is set to be on August 12’th with the following agenda:

1. Introduction to the User Group
2. Basic topic: The new mapper in BizTalk 2010 by Jan Eliasen
3. Advanced topic: Introduction to WF4 by Christian Stærk
4. Tools of the Trade: Pipeline Component Wizard by Jan Eliasen

So as you can see, I’ll be speaking twice :) And unless someone else has a great topic, I have an advanced topic lined up for the next meeting as well.

You can find the official invitation here:

Everyone is invited, so please spread the word and the invitation.

Thanks

Hi all

I just had the funniest (NOT) experience (AGAIN) with the new BizTalk 2009 project system.

Somehow I had gotten into a situation, where I could add all the usual artifacts to a BizTalk project except schemas. I could add orchestrations, send pipelines, receive pipelines, maps, flat file schemas, property schemas, and flat file wizard schemas. So the only thing I couldn’t add was “normal” schemas.

I thought: Who cares? I can just add either a property schema or a flat file schema instead and then change the necessary properties on it to make it a normal schema, and that worked for me for some time.

Then, I was contacted by Microsoft to test out a new QFE package that they have created to fix an issue I have reported. The QFE package wouldn’t install, so i thought it might have something to do with my project system being broken, so I chose to repair my BizTalk installation.

The result was, that now I can add “normal” schemas, but I can’t add orchestrations and property schemas. Also, naturally, the QFE package still doesn’t install :-( So I ended up unconfiguring, uninstalling, reinstalling and reconfiguring. Everything seems normal now. But for how long?

I really hope they have improved the project system for BizTalk 2010.

Hi all

Frequently I get emails from people looking for my help with some BizTalk challenge they are facing. Some times I just get a zipped version of a project containing schemas and other artifacts that don’t even have anything to do with the issue – it was just easier to send the entire thing and hope that I can figure it all out.

So here comes a plea from me to all you people looking for help: Please, when you send someone an email asking for help, prepare an SSCCE (See more here: http://sscce.org/).

I have plenty of things to look at, so if you take the time to prepare an SSCCE the chances of me helping you increases by a multitude of 10

Thanks!
