Generally, including the plugin and a JSR 303 compliant implementation in your project will cause the Struts 2 framework to apply the validation constraints you have included on your Bean classes. Note that the 1.0 version of the plugin does not allow you to combine both JSR 303 bean validation with the Struts 2 XML validation.</p> [More] Java Tue, 29 Oct 2013 08:38:00 -0700 /blog/index.cfm/2013/10/29/New-Struts-2-Plugin-For-JSR-303-Bean-Validation Using Spring Web MVC to Create a REST Web Service and Spring RestTemplate to Consume It /blog/index.cfm/2013/9/13/Using-Spring-Web-MVC-to-Create-a-REST-Web-Service-and-Spring-RestTemplate-to-Consume-It <h3>Introduction</h3> <p>As Spring continues to evolve each new release improves support for creating and consuming REST web services.

In this version, when <a href="" target="_blank">development mode is set to true</a> additional messages are written to the log. These messages include ones that indicate whether or not a specific parameter will be handled by the parameter interceptor and made available to the Action class. These log messages can be helpful in clearly identifying parameters that you do not want the parameter interceptor to process for security or other reasons. This article discusses how to exclude parameters from being handled by the parameter interceptor.</p> [More] Java Mon, 31 Dec 2012 17:29:00 -0700 /blog/index.cfm/2012/12/31/Struts-2-How-To-Exclude-Parameters-From-Being-Processed-By-The-Framework Spring Release 3.2 - Easier Spring MVC Tests /blog/index.cfm/2012/12/20/Spring-Release-32--Easier-Spring-MVC-Tests <h3>Introduction</h3> <p>I've been learning how to use the Spring MVC web application framework as I contemplate switching from Struts 2 to Spring MVC. In December 2012, <a href="" target="_blank">Spring announced the release of version 3.2</a>. One of the new features in this release is easier testing of Spring MVC applications (which is a weak area for Struts 2). So this article provides a simple Spring MVC example project that includes JUnit tests of the Spring MVC controller class.</p> [More] Java Thu, 20 Dec 2012 12:41:00 -0700 /blog/index.cfm/2012/12/20/Spring-Release-32--Easier-Spring-MVC-Tests Blackboard Building Block Development - Setting The Initial Sort For An inventoryList /blog/index.cfm/2012/12/11/Blackboard-Building-Block-Development--Setting-The-Initial-Sort-For-An-inventoryList <h3>Introduction</h3> <p>We needed to display a list of Blackboard Course objects on a view page and wanted the list to be sorted by a specific field (courseId). We used the inventoryList Blackboard tag to display the list. Consulting the <a href="" target="_blank">Blackboard Learn Building Blocks Tag Library Guide for Release 9.0 and 9.1</a>, I found that the inventoryList tag has an attribute, initialSortCol with this description:</p> <blockquote><em>The column to initially sort by when the list is displayed. The value should match the name of a list element.</em></blockquote> <p>So we set the value of initialSortCol to be the name value for the listElement tag that displays the course ID for each Course object in the collection. But the list of Course objects still was not sorted correctly.</p> <p>Thanks to some bright colleagues where I work, we were able to get the list sorted correctly. Hopefully this article will save other developers hours of frustrating work caused by incomplete and missing Blackboard documentation.</p> [More] Java Tue, 11 Dec 2012 10:33:00 -0700 /blog/index.cfm/2012/12/11/Blackboard-Building-Block-Development--Setting-The-Initial-Sort-For-An-inventoryList A Blackboard Building Block That Allows Instructors To Merge Blackboard Courses /blog/index.cfm/2012/11/1/A-Blackboard-Building-Block-That-Allows-Instructors-To-Merge-Blackboard-Courses <p>My university is moving to Blackboard Learn 9.1 Service Pack 9 and to <a href="" target="_blank">Oracle's Student Administration and Integration Pack</a> (SAIP). We will be using SAIP to provide all our classes and enrollments to Blackboard so that each class has an associated Blackboard course. As part of these changes we need to implement a Building Block (B2) that will allow instructors to add one or more child courses to a parent course in Blackboard. Some of our instructors prefer to have one Blackboard course for multiple sections of the same class they are teaching or to have one Blackboard course for both their lecture and lab sections. </p> <p>This article discusses our research into creating such a Building Block and the Blackboard API classes we use. There is a prototype Building Block available on <a href="" target="_blank">my Github repository</a>. I want to share what we've learned, but I also hope to get feedback on our approach and any lessons learned from others experiences.</p> [More] Java Thu, 01 Nov 2012 09:35:00 -0700 /blog/index.cfm/2012/11/1/A-Blackboard-Building-Block-That-Allows-Instructors-To-Merge-Blackboard-Courses How To Use The Blackboard Building Block Eclipse Plugin /blog/index.cfm/2012/10/25/How-To-Use-The-Blackboard-Building-Block-Eclipse-Plugin <p>Blackboard provides a Building Block Eclipse plugin that simplifies setting up a Building Block project and deploying a Building Block application to a Blackboard development server.

I've posted these examples<a href="" target="_blank"> on my GitHub repository</a>. Hopefully other new Building Block developers will find them helpful.</p> <p>Blackboard Building Blocks are Java web applications that run in the Blackboard Learn platform. Building Blocks allow schools to extend what Blackboard Learn can do or customize what it currently does. Blackboard provides an <a href="" target="_blank">extensive API</a> and also a <a href="" target="_blank">JSP tag library</a>. The downside is that as of <s>October 2012</s> July 2013 (!) there is little documentation on how to develop Building Blocks for the Blackboard Learn 9.0 and 9.1 platforms. Much of the documentation available is too old. </p> [More] Java Mon, 22 Oct 2012 14:28:00 -0700 /blog/index.cfm/2012/10/22/Building-Block-Examples-For-Blackboard-Learn-91 Tutorial On Using Building Block Feature That Creates Database Tables In the Blackboard Database /blog/index.cfm/2012/10/12/Tutorial-On-Using-Building-Block-Feature-That-Creates-Database-Tables-In-the-Blackboard-Database <h3>Introduction</h3> <p>Beginning with Blackboard Learn 9.1 Service Pack 1, Blackboard enabled a Building Block (B2) to create database tables in the Blackboard Learn schema and insert records into those tables when the Building Block is deployed to the Blackboard Learn application server (ref. 1). This makes it simpler for B2 applications that need to store data in database tables, especially if those tables should contain foreign keys to other Blackboard tables. </p> <p>The documentation available on how to setup a Building Block so it creates the tables and inserts records into the tables is very limited (at least what I could find) and confusing. After I learned how to do this I thought a tutorial and example on how to have a B2 create tables and insert records that are part of the Blackboard Learn database schema would be useful for other B2 developers.</p> [More] Java Fri, 12 Oct 2012 14:51:00 -0700 /blog/index.cfm/2012/10/12/Tutorial-On-Using-Building-Block-Feature-That-Creates-Database-Tables-In-the-Blackboard-Database References For Blackboard Building Block Development For Blackboard Learn 9.1 /blog/index.cfm/2012/10/2/References-For-Blackboard-Building-Block-Development-For-Blackboard-Learn-91 <h3>Introduction</h3> <p>The university I develop Java applications for needs to create some Building Block (B2) applications for Blackboard Learn release 9.1 service pack 9. I'm somewhat familiar with Blackboard's Building Block technology but needed to update my knowledge for Building Blocks that will work with Blackboard Learn release 9.1 service pack 9.

I'm currently using Eclipse 3.7. Recently NetBeans 7.2 beta was released and I decided to give it a try. I'm working on refactoring/improving a large Java project that was written over 4 years ago. I'm adding Spring, Maven, unit tests and improving the projects flexibility and maintainability. I spent a day using NetBeans 7.2 beta instead of Eclipse to see how well I liked using NetBeans.</p> [More] Java Fri, 25 May 2012 16:30:00 -0700 /blog/index.cfm/2012/5/25/NetBeans-Java-IDE-72--Comments-From-An-Eclipse-User
