The aim of this paper is a brief introduction to MDA technology and a summary / comparison to the approachments to MDA of AndroMDA and Acceleo, intending to be a practical and understandable summary Introduction Model-driven architecture (MDA) is a software design approach for the development of software systems. It provides a set of guidelines for the structuring of specifications, which are expressed as models. It was launched by the Object Management Group (OMG) in 2001 The Model-Driven Architecture approach defines system functionality using a platform-independent model (PIM) using an appropriate domain-specific language (DSL). One of the main aims of the MDA is to separate design from architecture. As the concepts and technologies used to realize designs and the concepts and technologies used to realize architectures have changed at their own pace, decoupling them allows system developers to choose from the best and most fitting in both domains. The design addresses the functional (use case) requirements while architecture provides the infrastructure through which non-functional requirements like scalability, reliability and performance are realized. MDA envisages that the platform independent model (PIM), which represents a conceptual design realizing the functional requirements, will survive changes in realization technologies and software architectures.

Apache ServiceMix is an open source ESB (Enterprise Service Bus) that combines the functionality of a Service Oriented Architecture (SOA) and an Event Driven Architecture (EDA)  to create an agile, enterprise ESB. Apache ServiceMix is an open source distributed ESB built from the ground up on the  Java Business Integration (JBI) specification JSR 208 and released under the Apache license. The goal of JBI is to allow components and services to be integrated in a vendor independent way, allowing users and vendors to plug and play.

"Eclipse BIRT is free / open source reporting engine for Java. A commercial BIRT Report Server is available from Actuate (the company behind Eclipse BIRT). While Eclipse BIRT does not provide a free/open source reporting server, the BIRT Runtime provides a simple Eclipse BIRT Web Viewer. Eclipse BIRT Web Viewer installation instructions for several Java EE application servers are here. Here I share my own experience installing Eclipse BIRT 2.6.1 Web Viewer under GlassFish 3.0.1 Java EE Application Server :"

If you have web hosting account, you need to think about its security. There are many viruses, which will harm your web hosting. So that you need Security for your web hosting account. Here you can get all information about security tips for web hosting.

This article explains how to develop RESTful web services in Java with the JAX-RS reference implementation Jersey. In this article Eclipse 3.5, Java 1.6, Tomcat 6.0 and JAX-RS 1.1. (Jersey 1.1.5) is used.

"If you didn't know already, Eclipse allows you to define custom templates for commonly used code snippets. Its a very neat feature for those of us who are memory challenged or don't like typing things twice! I think that Apache Camel users could really benefit from having predefined templates for doing Camel routing. I also hear a lot of requests like "I have this Java DSL route, how do I do this in the Spring XML DSL?" so having both Java and XML templates for the same thing is essential."

When you write Eclipse plug-ins sooner or later you will start thinking about testing your work. The very first steps will lead you to the Internet. But to my (and maybe your ;) ) surprise this information is not very easy to find. I know two ways to accomplish this task and I want to describe the first one - testing Eclipse plug-ins using build-in JUnit support.

WindowBuilder Pro (also known as just WindowBuilder) is a powerful and easy to use bi-directional Java GUI designer. It is composed of SWT Designer, Swing Designer and GWT Designer and makes it very easy to create Java GUI applications without spending a lot of time writing code to display simple forms. With WindowBuilder Pro you can create complicated windows in minutes. Use the visual designer and Java code will be generated for you. You can easily add controls using drag-and-drop, add event handlers to your controls, change various properties of controls using a property editor, internationalize your app and much more.

Apache XML-RPC is a Java implementation of XML-RPC, a popular protocol that uses XML over HTTP to implement remote procedure calls. Version 3 of Apache XML-RPC is still compliant to the XML-RPC specification. However, the user may enable several vendor extensions are available, that greatly extend the power of XML-RPC: All primitive Java types are supported, including long, byte, short, and double. Calendar objects are supported. In particular, timezone settings, and milliseconds may be sent. DOM nodes, or JAXB objects, can be transmitted. So are objects implementing the java.io.Serializable interface. Both server and client can operate in a streaming mode, which preserves resources much better than the default mode, which is based on large internal byte arrays.

Eclipse Rich Client Platform has come a looong way since it was first introduced (and used in Eclipse IDE). The new Eclipse RAP (Rich Application Platform) is also becoming more and more attractive for deploying existing or new Eclipse RCP applications to the web. One of my the projects I'm working on is developed on top of Eclipse RCP. It uses additional plugins such as EMF (Eclipse Modeling Framework) including EMF Editor UI, Teneo (EMF Persistence for Relational Databases), and Hibernate. After some work, I managed to run the whole application on both Eclipse RCP (desktop) and Eclipse RAP (web-based). See the screenshots for proof. Thanks to the recently released EMF Support for RAP I don't have to let go any of the nice EMF generated editor UIs for the web-based RAP version. What's amazing is how little the work I have to do to port the RCP app to RAP. The changes I needed to do is not changing code, but juggling dependencies to plugins and/or packages. Also creating a few platform-specific plugins (different based on whether I deploy on RCP or RAP).

" In general when people think about running a Java based application server with Apache as front-end they almost always think about using mod_jk to proxy to Glassfish, but you can also use mod_proxy quite effectively. If you are wanting to proxy from a HTTPS Apache to a HTTP Glassfish then this article describes how you can do that. "

"The concept of automatic incremental compilation is not familiar to many developers. A very frequent question from Eclipse beginners is, "where is the compile button?" The answer is that an IDE with automatic compilation doesn't need a compile button. Every time you make a change to a file, or a group of files, the incremental builder immediately rebuilds every source file that was affected by the change. In this environment, the idea of compilation as a task the user is involved in disappears -- the world is just always in a compiled state. So what magic goes on behind the scenes to make this happen? How does the Java™ builder know which files need to be recompiled when a given source file changes? This is no easy task, but in broad brush strokes, this is what the Eclipse Java builder does: "

"This article looks at the new Jobs API available as part of Eclipse 3.0. It describes the main portions of the Jobs API and the use of scheduling rules. It also describes some changes to Eclipse resource management including how the Resources plug-in integrates with the new API. Finally, it describes some new UI functionality that has been added to provide feedback to users about jobs that are run in the background. "
