Reflective Ecore Model Diagram Editor is a GMF based Eclipse plugin which provides a graphical editor for any EMF model file, using only the meta-model such as .ecore and .xsd file. You don't need any .gmfgraph, .gmftool, .gmfmap, or .gmfgen files. This editor is, say a diagram version of Reflective Ecore Model Editor included in EMF.

t just works - Migrate from any version (incl. an empty database) to the latest version of the schema Automatic migration on startup - Ship migrations together with the application and run them automatically on startup Convention Over Configuration - Classpath Scanning to automatically discover Sql and Java migrations Plain Old Sql - SQL scripts for regular migrations (incl. placeholder replacement). No proprietary XML formats, no lock-in. No limits - Java classes for advanced migrations Highly reliable - Safe for cluster environments (Multiple machines can migrate in parallel) Maven support - Maven plugin for migrating manually Fail fast - Inconsistent database or failed migration prevents app from starting. Schema Clean - Drop all tables, views, triggers, ... from a schema without dropping the schema itself

"At this point, the only source of useful overview documentation for the Common Navigator are the excellent tutorials at Michael Elder's (the author of the CN) blog. Soon I hope to get some of this transferred into the Eclipse Plugin Developer's Guide. RCP applications can quickly and easily use the CN to show the resources in the workspace. This assumes that your RCP application uses resources (which is another discussion). The CN can also be used for non-resource RCP applications, in that case, these instructions don't apply, as the objects treated by the CN have to be created directly by the RCP application. If you are planning to use the CN in an RCP application that uses resources, there are 3 (2 of which are completely undocumented) things you must do:"

"The RHQ project is a systems management suite that provides extensible and integrated systems management for multiple products and platforms across a set of core features such as monitoring and graphing of values alerting on error conditions remote configuration of managed resources remote operation execution The project is designed with layered modules that provide a flexible architecture for deployment. It delivers a core user interface that provides audited and historical management across an entire enterprise. A Server/Agent architecture provides remote management and plugins implement all specific support for managed products. RHQ is an open source project licensed under the GPL, with some pieces individually licensed under a dual GPL/LGPL license to facilitate the integration with extended packages such as Jopr (now included in RHQ) and Embedded Jopr."

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.

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.
