Google provides a scalable application hosting environment called Google App Engine (GAE). One of the many benefits of GAE is that hosting small scale applications is 100% free. Google starts charging for hosting when your application resource requirements start to grow.

So I started with a maven web application in Eclipse to do my test drive of jersey. I added the repositories, and the jersey-server dependency (https://jersey.dev.java.net/source/browse/*checkout*/jersey/tags/jersey-1.0.2/jersey/dependencies.html) I started out with a filter, instead of the servlet. I always prefer filters. I also added the following initialization parameters:

" Xtext has been released as a part of the Eclipse Galileo release train on June 24th, 2009. Xtext is a framework for building DLSs (domain specific languages). In fact, it can be seen as a DSL for defining DSLs. In this article, we will develop a small DSL for defining entities."

"Let's imagine we want to create an application for orders. People can sign in to the system, place orders for various items, check out and have them sent to their address. Very simple, but we can show a lot of things here. As we expect to be writing more than one application of this type and as we also would like to be able to express the structure of the application on a business level (one of the major drivers for DSLs and MDSD for that matter), we come up with the idea of using a DSL to describe what the application does. Defining the DSL is what we did last week. This week, we need to map the concepts of the DSL to some code and some APIs we're going to program against. So, we're going to create a set of code templates for a code generator that can then read our DSL models and create persistence code for us."

Vaadin is a Rapid Application Development (RAD) framework for RIA applications. I only know it for a few months but since I started experimenting with it, I'm really in favor of it. I see a lot of advantages compared to Sun's Java EE standard front-end framework JSF. First of all Vaadin is a java library, so you only have to write Java to build a complete frontend. No need for a specific frontend language, no need for converters (for comboboxes),… This also implies that you can use the full Java power on the frontend side and that's an huge advantage because frontend code is now type-safe and easily refactorable. You can unit test your frontend with JUnit. You can also use all existing java libraries on the frontend side, for example LOG4J. Another advantage is the fact that Vaadin is easy to learn (JSF isn't!) and to use: it's straigtforward. It feels like developing desktop apps and for me developing desktop apps feels much more intuitive than developing web-apps the way I'm used to. Vaadin uses convention over configuration. No need to register new components, validators or whatever in different xml files. Themes have a default folder and a default folder structure. Vaadin is very well documented. There's the book of Vaadin wich explains every aspect of the framework very clear. On the site there's a blog, a FAQ section, a wiki, a forum, examples with Java source code, … It's very easy to extend. Want to create your own Validator? Just implement an interface or extend another Validator and use it. Want to create your own custom server side component? Just extend the CustomComponent class or extend from another component. There's also an add-on directory where you can download UI components, data components, tools, themes, …

Xtext - Language Development Framework With Xtext you can easily create your own programming languages and domain-specific languages (DSLs). The framework supports the development of language infrastructures including compilers and interpreters as well as full blown Eclipse-based IDE integration. While Xtext equips you with a set of sensible defaults, you can tweak every single aspect of your language with Xtext's powerful APIs. A comprehensive documentation as well as the vivid community will help you getting started in no time. And if that is not enough you can buy trainings, consulting or support contracts delivered directly by the committers.

modeling workflow engine (MWE) supports orchestration of different Eclipse modeling components to be executed within Eclipse as well as standalone. Based on a dependency injection framework, one can simply configure and wire up 'workflows' using a declarative XML-based language. The project provides the runtime used to execute workflows as well as the IDE tooling used to edit, start and debug them.

This page contains links to applications built on the Eclipse Rich Client Platform (RCP). The listings here are intended to get you started in finding out more about products and projects that use the Eclipse RCP. You can also view a pdf presentation of RCP based applications. We have also prepared some case studies of organizations that are using Eclipse RCP. Hopefully it will provide you a better understanding of the benefits from using Eclipse RCP for your application platform. We'd like these pages to be useful to you - so please email us your pointers and comments!

Here you will find the pom.xml for kettle plugin and the plugin-lib.xml that is used by the maven assemble plugin. Use one of exemplary plugins to start development of your own plugin.

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.

"Libra is an open source project under the Eclipse Web Tools Platform Container Project. It provides standard tools for OSGi Enterprise application development and in particular tools that integrate the existing WTP and PDE tooling so that OSGi Enterprise applications can be developed with both tooling at the same time. Libra also will enable users to work with tools for better experience in the Server-Side Equinox scenario. The goals of the project are: Providing tools for creation of deployable artifacts for application servers implementing the OSGi Enterprise specification, e.g. wizard for creating new Web Application Bundle projects. Providing tools for converting existing Java EE deployable artifacts to OSGi Enterprise deployable artifacts, e.g. wizard for converting Dynamic Web projects to a Web Application Bundle projects. Contributing tools for editing and validation of the metadata of OSGi Enterprise artifacts, e.g. extension of the PDE Manifest Editor for editing manifest headers that are specific to Web Application Bundles. Developing OSGi server adapter, providing basic implementation of configuring an OSGi-based application server, starting it and deploying OSGi enterprise artifacts. This server adapter should be customizable and extensible by adopters. Delivering tools that improve the experience of developing Server-Side Equinox applications. Extending the tools in scope, so adopters can apply them depending on their own application model."
