JSP Toolkit - Integration between Blackboard and Keystone (2)

suy — Tue, 24 Jun 2008 18:04:01 +0100

Hi Andy,

We've solved the problem. As you've suggested in (3), we found out that our blackboard server didn't have permission to see our talis server through the firewall. After our network engineer modified the firewall rules, the problem is solved. Now our students can see their library account summary when they use blackboard.

Many thanks,

Hi Andy,

Many thanks for the suggestions. To answer your questions 1 and 2 first, I can confirm that there is no problem with our keystone service or with any of the dummy student IDs we have been using. The fact is the blackboard building block works fine on our development server, and we can see all the dummy students' library account summaries on our blackboard development server.

We're still talking to our network manager to see if there is any problem with our live blackboard server as you've suggested in 3.

So far, we don't see a need for a support call, yet. I'll get back to you when I have more info from our network manager.

Many thanks,

Can I check a few things please

Hi Su,

An IO exception would indicate that a call to the web services has failed somehow. Can I check a few things please:

1) Is your local Talis Keystone service started up OK? Can you See the Talis Keystone service in a web browser for example?

2) Does the borrower you have requested exist in your system? If it doesn't I would have expected the error to be more meaningful than this, but just so i can be sure...

3) Does your live blackboard server have permission to see the port on which Talis Keystone is running? You could check this by logging into your live blackboard box and opening up a telnet session to the Keystone port on the Prism server (default port is 8080 btw) and sending in a HTTP GET request. All of this assumes that keystone has started up on your system, as per question (1)...

4) I don't think the version of Java is an issue here. If you were running the Toolkit with a JVM version which is previous to the one the Toolkit was compiled with I would not expect you to have got this far. You would have seen a major/minor class error in the stack trace.

If you could check your keystone system and validate the borrower in the first instance and let me know then that would be great! If all this is ok we can continue trouble shooting this for you.

Would you like to open up a support call for this?

Many thanks,

-Andy

JSP Toolkit - Integration between Blackboard and Keystone (2)

Hi,

I've posted a previous message here regarding some socket permission problem while integrating Blackboard with keystone service. This socket permission problem happened while we were working on our blackboard development server. With your help, the socket permission problem was solved, and we have no problem to integrate our keystone service inside our blackboard development server.

Now we moved onto our blackboard live server, and we encountered a strange problem.

We are able to call the sandbox keystone service (http://sandbox.talis.com/TalisKeystone/ViewMyAccountRESTService) from our live blackboard server without any problem.

But once we changed the ViewMyAccountToolkit.properties file to point to our own keystone service, I got this Unable to invoke REST service due to IOException error. The detailed messages are:

Creating borrowerIdentifier object.
com.talis.integration.services.BorrowerIdentifier [BORROWER ID=9686883] [BORROWER ID TYPE=InstitutionIdNumber]
Creating BorrowerAccount object.
com.talis.integration.services.ClientServiceException: Unable to invoke REST service due to IOException [Ljava.lang.StackTraceElement;@18c24b9

You can see the exception happens when trying to create the BorrowerAccount object. I tried to trace the stack info, but couldn't find any useful info there.

The thing I don't understand is why the live blackboard server is able to invoke the sandbox service without any problem, but got the IOException error when connecting to our own keystone service.

Could the version of Java on the blackboard server be an issue?

What does, "com.talis.integration.services.ClientServiceException: Unable to invoke REST service due to IOException", usually indicate? Is there anyway we can trace more info about this IOException problem?

I'm running out of ideas, please help.

Thanks in advance.

Hi,

< permission type="socket" name="*" actions="accept,connect"/> solved the problem.

Many thanks,

Hi,

I believe this is a security issue with the Blackboard server, which is preventing outbound connection to the TalisKeystone server. So I would strongly recommend that you speak to your Blackboard server admin and modify the policy file.

My knowledge of Blackboard is limited but I think if you add the following lines in the bb.manifest.xml file , between the opening and closing <permissions> tags, might resolve your problem:

Hope this helps.

Please let us know how you get on.

JSP Toolkit - Integration between Blackboard and Keystone

Hi,

Our uni is in the process of integrating Keystone into our Blackboard system. In case you haven't heard of Blackboard, it is a virtual learning envrionment, that is developed on JAVA platform, and generally sits on a linux box.

So your JSP Toolkit is obviously the best choice. I've downloaded the JSP Toolkit, and tried it on my local Tomcat server. It worked fine. I can connect to your sandbox server. I can connect to our Keystone server without any problem.

The problem happened when I installed the JSP toolkit onto our Blackboard server in the form of a building block. The exception I got is:

-----------------------------------------------------------------------------------
java.security.AccessControlException: access denied (java.net.SocketPermission sandbox.talis.com:80 connect,resolve)
-----------------------------------------------------------------------------------

It seems more like a security policy problem. I just wondered if anyone has heard of this problem before when using the JSP toolkit.

Why the toolkit worked fine on one tomcat server, but not another?

Should I ask our Blackboard server admin to modify the policy file on the Blackboard server?

Thanks in advance.

I'm using the Windows (zipped) extraction wizard. I think it is the default extraction tool that came with Windows XP.

Hi Jane,

I've just tried to unzip the .NET toolkit and it extracts without a problem - Can you try downloading again and unzipping on another machine, if that fails can you post the error that you get?

We need to test keystone working with .net. Unfortunately, we get an error when trying to unzip the toolkit.
