HTTP Adapter (BizTalk Server Sample)

 

The HTTP Adapter sample demonstrates how to implement the request/response and solicit/response communication paradigms used in BizTalk Server.

<Samples Path>\AdaptersDevelopment\HttpAdapter\

The following table shows the files in this sample and describes their purpose.

File(s)

Description

\Design-Time\Adapter Management

Contains the project that implements the design time portion of this adapter.

\Run-Time\HttpReceive

Contains the project that implements the request/response adapter communication pattern. This is an isolated receiver.

\Run-Time\HttpSend

Contains the project that implements the solicit/response adapter communication pattern.

This sample is meant as a framework for you to use in developing custom adapters. In some cases BizTalk Server may need to transport messages to a specific custom application or use a protocol for which a native adapter that does not exist. Third-party companies have written adapters to support additional protocols. You may want to determine if there is an adapter for your protocol before deciding to write a custom adapter. If you are unable to locate an adapter to support your communication requirements, you can develop your own custom adapter.

Writing a custom adapter can be a challenging exercise. To simplify this process Microsoft has developed a foundation called the Adapter Framework. You can use this framework as a basis for your development along with sample adapter source code in the BizTalk Server SDK. For more information on custom adapters, and the Adapter Framework, please refer to the See Also section at the end of this document.

System_CAPS_importantImportant

If the BizTalk installation is 64-bit or the location of installation is modified, OutboundAssemblyPath, InboundAssemblyPath, AdapterMgmtAssemblyPath would need to be changed accordingly.

To build and initialize the HTTP Adapter sample

  1. In a command window, navigate to the following folder:

    <Samples Path>\AdaptersDevelopment\HttpAdapter

  2. Run the file Setup.bat, which performs the following actions:

    • Compiles the HTTPAdapter and all of its dependencies.

    • Creates an Internet Information Services (IIS) application used by the receiver side of the adapter.

On IIS 7.0, you must ensure the identity of the application pool running this IIS application is a member of the following groups:

  • BizTalk Isolated Host Users group.

  • IIS_WPG group.

  • On IIS 7.0, you must migrate the application to work with the Integrated .NET mode. You can migrate the application configuration, including the contents of the <httpHandlers> configuration section, by using the following from a command line window (the window must be running as Administrator):

    %systemroot%\system32\inetsrv\APPCMD.EXE migrate config "Default Web Site/HttpReceive"
    
  • After you migrate your application, it will run in both Classic and Integrated .NET modes, as well as on downlevel platforms.

System_CAPS_noteNote

You should confirm that no errors were reported during the build and initialization process before attempting to run this sample.

System_CAPS_noteNote

If you choose to open and build the projects in this sample without running the file Setup.bat, you must first create a strong name key pair using the .NET Framework Strong Name Utility (sn.exe). Use this key pair to sign the resulting assemblies.

System_CAPS_noteNote

To undo changes made by Setup.bat, run Cleanup.bat. You must run Cleanup.bat before running Setup.bat a second time.

To register the HTTP Adapter sample

  1. In Windows Explorer, navigate to the installation drive for BizTalk Server, and then navigate to <Samples Path>\AdaptersDevelopment\HTTPAdapter.

  2. To add the sample adapter to the registry, double-click HTTP.NET.reg.

    System_CAPS_noteNote

    HTTP.NET.reg includes hard-coded paths to the BizTalk Server installation directory. If you did not install BizTalk Server in the default location or if you upgraded your BizTalk Server installation from a previous version of BizTalk Server, you must modify the file HTTP.NET.reg with the appropriate paths. Update the paths associated with the "OutboundAssemblyPath" and "AdapterMgmtAssemblyPath" values to point to the correct location of the specified files.

    System_CAPS_importantImportant

    If you install BizTalk on a 64 bit machine, change all instances of the HKEY_CLASSES_ROOT\CLSID\ registry entry to HKEY_CLASSES_ROOT\Wow6432Node\CLSID\ in the HTTP.NET.reg registry file.

  3. In the Registry Editor dialog box, click Yes to add the sample adapter to the registry, and then click OK.

  4. To close Windows Explorer, on the File menu, click Close.

To install the HTTP Adapter sample

  1. Click the Start menu, select All Programs, select Microsoft BizTalk Server 2013 R2, and then select BizTalk Server Administration.

  2. In the BizTalk Server Administration console, expand the BizTalk Server Administration tree, then expand the BizTalk Group tree, then expand the Platform Settings tree.

  3. Right-click Adapters, click New, and then click Adapter.

  4. In the Adapter Properties dialog box, do the following.

    Use this

    To do this

    Name

    Type HTTP.NET.

    Adapter

    Select HTTP.NET from the drop-down list.

    Description

    Type Sample HTTP.NET Adapter.

  5. Click OK.

  6. The adapter now appears in the list of adapters in the right window of the BizTalk Administration console.

To stop and restart the host instance for the HTTP Adapter sample

  1. Click the Start menu, select All Programs, select Microsoft BizTalk Server 2013 R2, and select BizTalk Server Administration.

  2. In the BizTalk Server Administration console, expand the BizTalk Server Administration tree, then expand Platform Settings, and click Host Instances.

  3. In the results pane, right-click the host instance (typically, the computer name), and then click Stop.

    The status of the host instance changes to Stopped.

  4. In the results pane, right-click the host instance, and then click Start.

The HTTP.NET adapter is now ready to be used by your application. When configuring the adapter, the format for the Virtual Directory transport property is of the form: /httpreceive/httpreceive.aspx?optionalQueryString.

The HTTP.NET adapter makes use of the BaseAdapter classes provided in <Samples Path>\AdaptersDevelopment\BaseAdapter\v1.0..2\. The classes provided in the BaseAdapter project are intended to accelerate adapter development. Refer to the BaseAdapter code comments for details about the classes provided.
