TiTLi is a Google-like search tool for relational databases . It builds on top of Apache Lucene to provide an API and a GWT-based UI for searching multiple databases from various vendors simultaneously. It is very fast due to indexing, and the database is queried only when a record is chosen.
Simple Log is a small library that does logging very simply and requires you to do almost nothing (other than actually logging) to get log output to happen. It is much simpler to use than a logging framework, especially in terms of configuration. It doesn't attempt to solve every logging problem in one package, but contains enough features to be a viable alternative for most applications that need logging. This tool will handle the logging needs of most small- to large-sized projects, but with an almost non-existent learning curve.
WSO2 WSF/Spring provides an amazingly simple "Code First" approach to create Web services for the Spring user. This framework integrates the Apache Axis2 Web services engine into Spring. Thus, it provides all the power and versatility of the Axis2 engine to the Spring user. With just a few entries in the application context, this lets Spring users enjoy the benefits of Service Oriented Architecture using Web services in their applications.
The Spring Rich Client Project (RCP) is a sub-project of the Spring Framework. Spring-RCP's mission is to provide an elegant way to build highly-configurable, GUI-standards-following rich-client applications faster by leveraging the Spring Framework. It also provides a rich library of UI factories and support classes. Its initial focus is on providing support for Swing applications, but a goal of Spring-RCP is to be view agnostic as much as possible.
JCatapult is a development platform written in Java. Built for modularization, JCatapult allows developers to build modules such as a blog, content-management system, wiki, or any other reusable set of features and use them across multiple applications. Built on top of open source technologies, JCatapult is a robust and scalable platform. However, it is also agile and lightweight because it uses a convention over configuration approach.
