JInto is a plugin for Eclipse that lets the developer easily edit and maintain resource bundles (files that hold the localized strings for an application). It features parallel editing of all language versions (side by side), warnings when no text has been provided for a specific key, or when the text for one key is identical for different languages, and a search wizard to locate unused strings (strings that are referenced, but not actually defined in the resource bundle). It has been tested under Windows and Linux.
The Eclipe Eiffel Development Tools (EDT) are a set of plugins which implement a full-fledged, highly integrated Eiffel development environment based on the Eclipse Platform.

The Generic Eclipse Modeling System (GEMS) is a MDD tool for Eclipse that allows for the rapid development of visual modeling tools for Eclipse based on EMF/GEF. Developers specify the rules for a domain language using a metamodel and the tool generates a diagram editor plugin that enforces the rules from the metamodel. Interpreters can then be written to traverse the model and generate code, perform analyses, or execute the model. The tool supports complex model analysis using Prolog; Java, OCL, and Prolog constraints, remote model updating via CORBA, applying CSS styles to models, model-to-model linking, exportable templates, and more.
