CyberDemia CyberTester2

Changes:

• Implemented domain hierarchy segregation for users. This is particularly useful for administrator users. An administrator can now be restricted to only a sub-section of the domain hierarchy tree, thus can only access and modify users, tests and questions within the restricted sub-nodes.
• Moved all access authorization checks from delegates into session EJBs. This also means that session EJBs must be called by authenticated callers.
• Moved all User and Group related EJBs from Common sub-module into the CyberTester sub-module, to enable better integration of the users with the hierarchy tree nodes.
• Updated to use JBoss 4.2.0 GA.
• Upgraded Embeddable container to Beta 2. Unfortunately, unit tests are not working yet due to session EJBs requiring authenticated access.
• Added new JDBC driver to support MySQL 5.x.

Changes:

• Implemented reordering of questions that are assigned to a test with the administrator test editor.
• Changed ANT build script to package all Web Java classes into a jar file which is then put into the WEB-INF/lib within the war file.
• Written unit tests using JBoss Embeddable EJB3 container. In the Common module, unit tests are written at the session EJB level. In the CyberTester module, unit tests are written at the UI delegate level.
• Added INTEGER (single integer answer) and DECIMAL (single decimal value answer) question types.
• Fixed bug with modifying user roles.
• Fixed bug with determining end of test in multi-questions mode.

Changes:

This is the first released version of CyberTester2. Major improvements over CyberTester1:

• Rich text editing of question text using FCKeditor (only tested on Firefox browser).
• CyberTester2 will automatically detect a new installation and create a default admin user. Furthermore, JBoss will create the database schema properly without the need for any alteration. This eliminated the need to run any SQL script for a basic installation. Of course, SQL scripts can still be used to load test data or to optimize the database, e,g, index some columns.
• All tests will be evaluated at their conclusion. Users will be shown a final "Review Answers" screen where they can do a final check, prior to final submission of the answers. Removed the per-question feedback because this was just confusing and prevented the user from doing final reviews.
• Much cleaner code in the Web tier where all code had been moved from Struts actions into UI delegates that are independent of Struts. JSP pages and Struts forms had all been tidied up to better use Struts features properly, such as field error validation messages and multi-valued properties.
• Use of EJB3 enabled much simplier entity classes that are just POJOs, which also mostly eliminated the need for DTOs.
• Tidied up exception handling. All exceptions should bubble up to the top exception handler. Some custom exceptions have been annotated to roll back session EJB transactions.
• Upgraded to Java 5 with lots of nice coding features like generics and annotations.
• Lots of bug fixes.
• The entire CyberTester2 code-base has been grouped under a single CyberTester2 CVS top-module.
• Adoption of GPL for the entire application to simplify things.
