GWTruts is an easy-to-use framework for using GWT with MVC and dependecy injection. It virtually divides a GWT module into view, controller, and validation sections similar to traditional MVC Web frameworks like Apache Struts. It also provides a dependency injection mechanism similar to Spring, which you can use to customize your controllers and views. It provides a page decorator where you can define mappings between a URL and a group of controllers/views and sections of the HTML files.
GZRBOT is a port of GOZERBOT to the Google Application Engine. It is there for its code and reuse of it is highly recommended.

GZRBOT has a plugin system that lets you program your own plugin and provide you a way to add custom functionality to your bot. Both writing commands and reacting on events through callbacks is supported.
Gargoyle is an interface for small, widely available routers such as the Linksys WRT54G series and the La Fonera. It provides functionality above and beyond what the default software provides including sophisticated dynamic DNS, quality of service, and bandwidth monitoring tools. The primary goal is to provide a polished interface for these advanced tools that is at least as easy to configure as any existing firmware. This project is based on top of OpenWrt, but unlike other Web interfaces for OpenWrt it places a strong focus an usability and is meant for average users, not just power users.

GeoServer is a software server that allows users to share and edit geospatial data. Designed for interoperability, it publishes data from any major spatial data source using open standards. GeoServer is the reference implementation of the Open Geospatial Consortium (OGC) Web Feature Service (WFS) and Web Coverage Service (WCS) standards, as well as a high performance certified compliant Web Map Service (WMS). GeoServer forms a core component of the Geospatial Web.
Geomajas is an extensible spatial application framework, enabling integrated GIS solutions for businesses and government. It has an integrated client-server architecture, with a high focus on server-side integration of your data (be it through GeoTools or Hibernate). This means that you apply your security and business logic on the server before anything gets sent to the client, resulting in robust applications and a real thin client.
