Blackboard Single SignOn

Harold Harding — Wed, 08 Sep 2010 13:16:42 GMT

We are using BB 8 and want to create a custom SSO solution. I'm new to BB and cannot find any example code or posts showing how this would be done using JSP. I have made modifications to the custom login page but this doesn't provide what we need. I have all the user data, user id, password information for logging into BB but need to know how to pass it via JSP to create the user session, etc.

Can anyone aid?

thanks

Using bbNG:textbox under Struts

Nathan Davies — Tue, 07 Sep 2010 15:27:29 GMT

Hi,

I'm trying to develop a custom building block to enable our users to add some custom styled content. I want to use the VTBE within this and figure that the bbNG:textbox is the way to go. I discovered that for some reason Blackboard renames the element - suffixing it with 'text' and so I figured I could access it.

At present, when I save the content item it saves the title but not the body. I have managed to use content.setBody() before (when using a simple html text area) and I am using the same approach here. However, it appears that the body is not being set.

How do I get the content to save? As I say I am using struts and the actions pathway is working fine.The code I have for persisting the new content is:

public void defineNewContent()

{

content = new Content();

content.setContentHandler("resource/esf-contentblock");

content.setCourseId(getCourseId());

content.setParentId(getContentId());

}

-- this is used first to generate a content object? --

public void addContent(String title, String contentBody)

{

content.setTitle(title);

content.setBody(new FormattedText(contentBody, FormattedText.Type.HTML));

}

-- this is used to set the title and the body --

The calls are correct - at least I think they are spot on.

Any idea on this one anybody?

Cheers

Pencil Down Feature in Assessments for Blackboard 9.1

John Lane — Thu, 29 Jul 2010 17:15:36 GMT

Hello All,

First, I apologize in advance if this is an inappropriate area to post this question.

We are fast approaching our upgrade from Vista 8.x to Blackboard 9.1 and have a feature that is well regarded in Vista that is not in the new Blackboard.

In Vista, when a student is allowed one hour to take an exam, at the end of that time, Vista automatically saves any of the answers and submits the exam. This is not possible in the current implementation of Blackboard 9.1 The student is allowed to continue the exam and to take however long they want until conclusion.

We are aware of a solution from Princeton that allows us an instructor to place some code in the instructions portion of an exam but if it is not done just right, it causes some unexpected results and frustrations.

http://www.princeton.edu/bb/bbfaq/Endtime_Counter.htm

We would like to know if anyone has a better solution for this problem, or, if they would be willing to collaborate with us to build some sort of building block to address this concern.

Thank you all in advance.

University of York: 'Group Manager' Bb

Ian Gardner — Thu, 24 Jun 2010 16:09:26 GMT

Hello - I've made some changes to the Group Manager ('Batch Allocate Groups' tool) building blockand have it working well enough to add people to groups in 9.1

However, rather than the old 'student added to group' type message it now displays:

"Error creating bean with name 'messageSource' defined in class path resource [wikiApplicationContext.xml]: Initialization of bean failed; nested exception is java.lang.NoClassDefFoundError: Could not initialize class org.aspectj.weaver.reflect.Java15ReflectionBasedReferenceTypeDelegate"

Any ideas what I would need to edit to resolve this?

Thanks

Issue installing building block

Nathan Davies — Thu, 02 Sep 2010 12:03:07 GMT

Hi,

I've developed a building block that I wish to install on my development environment. I have done this succesfully in the past but after a recent upgrade to 9sp4 I get the following message;

Error: Could not install Building Block. Problem registering the package. blackboard.platform.plugin.VersionException: This Building Block uses Blackboard Content System functionality, but the Blackboard Content System is not installed. The Building Block cannot be installed.

The version for the building block has been moved on and the version for the application is correct. However, it will not load. I have contacted Blackboard customer support about this but they have been worse than useless.

Any help on this will be much appreciated

Many thanks

Added information item to course doesn't show up, what could be wrong?

Gerdien Jansen — Thu, 02 Sep 2010 08:34:00 GMT

I've created a building block function to create a content item that should appear in the Information section.

I've use the following code to create the content. The result says it's succesfully created. When I read the content via the API I get a result and find the item just stored.

However in the BB course itself I can't find the item created. Does anyone have an idea why I can't find it back?

    private ResultMessage createContentItem (String courseId, String contentData, String contentTitle) throws WebServiceException

Setting File Permissions with Building Block

Greg Frederick — Mon, 30 Aug 2010 14:38:49 GMT

Hi,

Is there a way to set file permissions for the content system in 9 with Building Block? I need to send a file to a third party and the only way I can do it is to change the permission to public. In the building block I want to change the permission to public, send link to third party, then remove public permission from file. Any ideas?

Thanks

How to clone a community AND have the guest settings retained

jrhoden — Mon, 10 May 2010 05:16:18 GMT

We are using the following code to clone a community. When we clone a community none of the guest settings under "Tools availability" are cloned correctly. The guest access setting defaults to on, even though in the source they are set to off.

The following allows us to do a clone and copy the main guest setting over manually:

	Organization template = OrganizationLoader.Default.getInstance().load(subject.template);
	Organization course = new Organization();
	String dataSourceKey = getDataSourceKey(subject.code, subject.type);
	DataSource dataSource = BlackboardHelper.getOrCreateDataSource(dataSourceKey);
	course.setBatchUid(subject.code);
	course.setOrganizationId(subject.code);
	course.setCourseId(subject.code);
	course.setTitle(subject.name);
	course.setDescription(subject.description);
	course.setRowStatus(IAdminObject.RowStatus.ENABLED);
	course.setIsAvailable(template.getIsAvailable());
	OrganizationPersister.Default.getInstance().insert(course);

	CloneConfig cfg = new CloneConfig();
	cfg.includeArea(CloneConfig.Area.ALL);
	CourseSitePersister.Default.getInstance().clone(subject.template, subject.code, cfg);

	// Ensure all details are correct after the clone has been completed
	course = OrganizationLoader.Default.getInstance().load(subject.code);
	course.setBatchUid(subject.code);
	course.setOrganizationId(subject.code);
	course.setCourseId(subject.code);
	course.setTitle(subject.name);
	course.setDescription(subject.description);
	course.setRowStatus(IAdminObject.RowStatus.ENABLED);
	course.setIsAvailable(false);
	course.setAllowGuests(template.getIsAvailable());
	course.setDataSourceBatchUid(dataSourceKey);
	OrganizationPersister.Default.getInstance().update(course);

How do you make sure other tools such as announcements, glossary, and so on also get their guest settings from the template? I continue to dig around trying to work it out, any pointers in the right direction much appreciated.

How can a caret page be created with bbNG tags?

Stephen Vickers — Sat, 03 Jul 2010 21:03:44 GMT

I am trying to follow the Blackboard Learn Design Framework and create a caret page. The closest tags I can find in the bbNG library are those relating to a landingPage. A bbNG:landingPageSection tag requires the name of a navigation item. I cannot see any public class which allows a NavigationItem instance to be created. Has anyone found a way to create a caret page without resorting to the bbUI tag library?

Thanks.

Linking the control to the content store.

LCD Admin — Fri, 27 Aug 2010 07:52:20 GMT

Hello,

Could someone please tell me how we can link an instance of a <bbUI:textbox> to our content area in BB9.1 please?

We used to (in BB 8) use the 'fileLocation' attribute on this tag and pass in a 'ContentFileLocation' object. This would allow us to store any uploaded files to the course directory in Blackboard. But now that the Content Store has been introduced, when we create the 'ContentFileLocation' object, it doesn't do anything with the new Content Store. It just stores the uploaded files in a temporary sessions directory.

We create the 'ContentFileLocation' as follows:
ContentFileLocation obj = new ContentFileLocation(contentDocument, ctx, request);

Does anyone know of the 'new' way of linking uploaded files into the Blackboard Content Store through a bbUI:textbox used in a building block?

Thanks in advance.

Using the colorPicker in bbNG

Dr Malcolm Murray — Mon, 23 Aug 2010 12:49:22 GMT

I've been a happy customer of the colorPicker widget in the old bbUI tag library for many years. I am now trying to use the NG version in some code and have always hit on a problem where it almost does what I want, but the dialog box fails to close when you click the Apply button. As the title colour value was conveniently ignored in early releases I wasn't too worried, but now as this bug has been fixed, I'm reviewing the functionality again.

I'm using it in a JSP that uses the <bbNG:learningSystemPage> tags and the business logic is contained within a <bbNG form> item. The form uses the onsubmit="return validateForm();" entry to take advantage of the built in javscript validation.

The colorPicker sits as a <bbNG:dataElement> within a <bbNG:step> which itself sits within a <bbNG:dataCollection> element. The entry looks like this:

<bbNG:dataElement isrequired="true" label="Colour" labelFor="titleColour">

<bbNG:colorPicker name="titleColour" isRequired="true" initialColor="#000000" />

</bbNG:dataElement>

It displays happily on the screen, with the default colour of black shown. When you click the current colour the dialog opens. You can choose a colour, but when you click the "Apply" button, the colour tile on the JSP is correctly repainted, but the text description still reads Black (a Henry Ford moment) and most annoying the dialog is NOT dismissed. The only way to get rid of the dialog is to click "Cancel". When you click "Apply" a JavaScript error occurs:

Error: $("dataCollectionContainer").getElementsByTagName("ul")[0] is undefined
Source File: https://myserver.place.edu/javascript/ngui/widget.js?v=9.0.539.0
Line: 1846

which seems to be triggered if I have the ShowUnsavedChanges flag enabled (as I do) in my <bbNG:dataCollection> tag.

Has anyone got this to work, and if so, would they mind sharing their code?

Many thanks,

Malcolm.

Authenticating a user via external application

Importing SCORM courses through Building Blocks

Vinod Borole — Thu, 19 Aug 2010 10:12:38 GMT

Hello,

Can any tell me how can i import SCORM courses through Building Block. I have searched through the API library of BB and i could not find any API that will do this for me. However i found few batch files and perl files under following location

blackboard\apps\content-exchange\bin

can this be used for SCORM course import, if not what else could be done?

Inserting data into a custom table created using OpenDB

Tanveer Virani — Tue, 24 Aug 2010 22:50:18 GMT

We're starting to look at a new building block and we've decided to start using the functionality provided by the open database. We have been able to get our tables to be created upon installation of the building block, however we've kind of hit a roadblock as how to insert data into these tables and what would be the best practice in this situation?

We were thinking to structure our code similar to how the CourseDbPersister works, but we're unsure if this is the best way to insert data. We were hoping that there would be a generic persister we would be able to use or if we are totally in the wrong area any help would be greatly appreciated.

Thanks!

Implementing CAS Authentication

Matt Mencel — Tue, 24 Aug 2010 22:03:13 GMT

I've been trying for a couple weeks now to implement CAS Authentication on our test WebCT Vista (8.0.3) system. I'm using the casssomodule.jar file found at the OSCELOT website. As far as I can tell everything is configured correctly.

However, when the CAS server passes the authentication ticket to the Service URL on the WebCT server....nothing happens. I just get redirected to the default entry page.

I've tried to add debug logging for the CAS module to the serverconfs/log4j files.....but nothing ever appears in any logs related to CAS.

We thought today....that since CAS depends on "com.webct.platform.sdk.security.authentication.module.AuthenticationModule" from the WebCT SDK...maybe we need to install the SDK somewhere on the system. But we tried putting the SDK jar file in "deployablecomponents" and "serverlibs"....but still nothing.

We're just stabbing in the dark here, because without any logging going on for CAS....we have no idea what to do to try to make it work. If anyone has any ideas or can help I would really appreciate it.

Thanks,

Matt

userBatchUID and studentId fields don't seem to populate in the UserVO object

Matt Scales — Thu, 20 May 2010 19:18:47 GMT

Hi,

I am working from a C# client connecting to the web services in Bb 9.1 as a proxy tool to work with user data. I have my project logging in and then connecting to the UserWS web service. When I do a .getUser(userFilter) call, it looks like nearly all of the fields return data (e.g. first name, last name, id, emailaddres), except the userBatchUID and studentId fields are blank.

When I run the Bb qa example application, I get the same thing. No data in the studentId and userBathUID fields. I checked the server and I know the studentId field is populated.

Thanks,

Matt

Why does Blackboard support not SUPPORT building blocks?

David Taylor — Mon, 07 Jun 2010 18:00:57 GMT

I am a building block developer at a university and I am a bit frustrated. Whenever I report a problem with the building block framework I get the same canned response. Here's the latest:

"My name is Tony and I will be taking case XXXXXXXX over from Rebecca. We are unfortunately unable to provide support for building block development. I suggest taking a look at www.edugarage.com. This is a valuable resource for developers and I am confident that you will find assistance here.

Best Regards,

Tony West

Technical Support Manager

Blackboard Client Support"

Here's my problem: I do *NOT* need help. I need Blackboard to fix what I consider to be an obvious (and likely overlooked) oversight. I'll describe it below. Basically, even though the database supports making building blocks available to the Observer role, the framework does not. Whenever I install this building block with what should be the proper parameters in the manifest file, I still have to go in and manually change values on the database to make it available to Observers. Here is my original report to them:

"I have a building block that I am modifying to work with the Observer role in Blackboard. I modified the manifest file of the building block to include the “can-allow-observer” option as shown below.

However, this appears to be broken in your building block framework. When I go to the APPLICATION table on the Blackboard database and look at the record for this building block, the CAN_ALLOW_GUEST_IND is set correctly to “Y”, while the CAN_ALLOW_OBSERVER_IND is *INCORRECTLY* set to “N”. I had to manually change this value in the database to be able to make my building block available to observers. This is most definitely a bug."

So as suggested, I am posting it here even though I've never gotten a response to anything I've posted here. I seem to have better luck on the listserv not run by Blackboard. I'll probably post it there as well. I hope I don't come across as irate, but I *am* a bit frustrated with their "support" considering how much money our institution spends on their software.

“resultsPerPage” property of tag

education.development — Wed, 18 Aug 2010 08:52:02 GMT

“resultsPerPage” property of <bbUI:list> tag doesn't work at Bb 9.1. And there is no this property in new tag <bbNG:inventoryList>.

In bb9, there are 25 records per page by default, how to show 1000 records per page?

Thanks.

Error activating building block

William Harvey Boyd — Wed, 18 Aug 2010 18:54:35 GMT

I'm working on a new custom building block, and whenever I activate the building block (in 9.1) an error appears in the stdout-stderr logfile. So far I've been unable to determine the cause of this error or what exactly it is about my block that causes the Bb code that is throwing the error to fail when I attempt to activate the block. It breaks the entire building block because we're using Spring and the error prevents the spring servlet from starting up.
