Accelerate the design and development of Java Enterprise Applications- This article shows how to apply Model Driven Architecture principles to accelerate the design and development of Java Enterprise Applications that use mainstream technology, such as Java Persistence API, Enterprise Java Beans and Java API for RESTful Web Services. It investigates each step of the model-driven development process from the initial domain design to the generation of EJB 3.0 and JAX-RS design and implementations.
The scope of this article is accelerating the design and development of Java Enterprise Applications that use mainstream technologies, such as Java Persistence API (JPA), Enterprise Java Beans (EJB) and Java API for RESTful Architecture. Following the principles of RESTful Architecture, I chose to model the Resources based on the entities that constitute the business domain. Enterprise Java Beans are used as an intermediate layer to take advantage of the transaction management support that they offer. IBM® Rational® Software Architect offers set of predefined model to code transformations that support development of Java Enterprise Applications with the mainstream technologies.

My name is Randy Simmons and I am a Rational Collaborative Lifecycle Management (CLM) Support Engineer specializing in the Requirements and Quality Management Tool. I was tasked to create a Video Series to give internal IBMer’s and external customers a basic understanding and troubleshooting options to use when Java related problems occur using the CLM suite of Tools.
This “Non-Programmer's Guide to Troubleshooting Java in CLM” video series covers the topics below. It will make you more aware of the Java Tools available for download at IBM DeveloperWorks. It give you some background about how Java and JVMs work, what data Rational Support is looking for, and the understanding of how you would go about troubleshooting Java or Performance related issues.
Click through the titles to watch the four videos, or click play on the embedded playlist at the end:
1. Introduction to Java for CLM: This video is a recording from an education session "Non-Programmer's Guide to Troubleshooting Java in CLM". This video provides an introduction to Java for IBM Rational Collaboration Lifecycle Management V5.0 users.
2. Garbage Collection in Java for CLM: This video provides an overview of Java Garbage Collection for IBM Rational Collaboration Lifecycle Management V5.0 users.
3. IBM Diagnostic and Monitoring tools for Java with CLM: This video provides an overview of some Java diagnostic and monitoring tools for IBM Rational Collaboration Lifecycle Management V5.0 users.
4. Interpreting Unresponsiveness with Java for CLM: This video provides some examples of what to do when experiencing Java unresponsiveness with IBM Rational Collaboration Lifecycle Management V5.0.
