Blackboard Learn 9.1 Web Services Tutorials and Documentation

Blackboard Learn provides extensive web services that external applications may use to get information from and add information to Blackboard. The below links can be used to learn about Blackboard Learn 9.1 web services and to download Java applications that demonstrate how to use the web services.

I wrote these Java example applications, tutorials and documentation based on updated versions of my previous blog articles on Blackboard Learn's web services. Each file includes a link to download an example Java application that can be viewed in any Maven compatible Java IDE. The example applications include a detailed ReadMe.txt file that explains how to build and run the example either in Eclipse or just using Maven.

These documents will become the references I will use in preparing my presentation on Blackboard's web services, which I'll give in July 2011 at the Blackboard Developer's conference.

Please use the Add Comment link below to provide any feedback. I'm especially interested in any feedback from Java developers who were not able to run the example applications with their own Blackboard installation.

Bruce, Thanks for your great documentation! We're using CF9 to try and pull Blackboard WS into a Liferay portal via a CF portlet (cfc). We're also authenticated using CAS. We finally got CF to deploy and not dump it's configurations whenever we updated cfcs. Now we'd like to access BbWS. What do you think will be the best method given our CAS'ified authentication. User or Proxy?

Baci - I'd still recommend using proxy. I think its the best approach that allows you to tailor the access for applications using that proxy.

Since your CFC functions will be interacting with the BB web service you should not have any issues with CAS.

If you get CF to interact with the BB web services please be sure to post that. There are several example applications that use Java or C# with BB web services, but nothing I know of that uses CF.

Also depending on what you need to do - it may be simpler to query directly the BB database. Blackboard does support select database queries and now publishes their database schema. If you just need to get information out of Blackboard, we've found querying the Blackboard database much simpler to implement.

Finally getting around to this. Thanks for the excellent documentation. We're in a managed hosting environment. I'm unclear about where the rampart.mar file needs to live. Im building the registerproxytool locally (not on the machine hosting our Bb 9.1 sp8 install. Does the rampart.mar need to be on the Bb server or can I path to it local to my eclipse application? Thanks for any assistance.

Baci - The rampart.mar goes on the same server where the RegisterProxyTool will run. If that's is your local computer then that is where rampart.mar goes.

Bruce, just a quick note to let you know we actually got this working. CF is now getting a proper response from our BbWS via loginTool. Now we can tear into the WS API. The most difficult part was to form the request xml (timestamp proved to be the most difficult). I hope to post the resolution, not sure where yet.

The CF code to interact with the BB web service, was that ever posted? Just wondering, due to having to begin a similar project here and CF seems to be the code of choice for the development.

This code is a big help. However, I am having a lot of trouble getting the web client to connect to the server. I have the BBLearn server running in a VM on my desktop machine and I have the example web client running on the same machine. I setup a host only network and I can connect with the browser to the URL but I cannot get the web service to communicate to this URL (set it in bbws.properties file).

I tried running the RegisterProxyToolApp with NetBeans 8, but got the following error message, did I miss anything?

Final Memory: 7M/162M
------------------------------------------------------------------------
Failed to execute goal org.codehaus.mojo:exec-maven-plugin:1.2.1:exec (default-cli) on project registerproxytool: Command execution failed. Process exited with an error: 1 (Exit value: 1) -> [Help 1]

To see the full stack trace of the errors, re-run Maven with the -e switch.
Re-run Maven using the -X switch to enable full debug logging.

Hi Bruce, first of all thanks for this great information, it is great to keep learning from you after bbworld.

I'm trying to install a proxy tool so I can use webservices from blackboard. After following every step as described in the document "How To Login Using A Proxy Tool" I'm having this error when Running As Java Application.

ERROR edu.ku.it.si.registerproxytool.controller.RegisterToolController.registerProxyToolWithBlackboard:84 - There was an error in registering the tool: [WSFW009]Rejecting webservice call: Service Context.WS is not active (operation: initialize)

It's weird because I already have available all of the webservices in my blackboard settings.

Would you please give me some advice?

Best regards!
Juan
