J4ME is a library to help with J2ME development. It includes a UI framework for professional-looking and intuitive interfaces, a logging framework to help debugging platform-specific issues found on different phones, a Bluetooth GPS integrated into the JSR-179 Location API, and a library of missing J2ME methods and helpful collections for small devices.
OpenHTMM is an implementation specifically designed to facilitate research into Hidden Topic Markov Models methods. Hidden Topic Markov Models (HTMM) is a method of analyzing a docyment by imposing a temporal Markov structure on the document. In this way, it is able to account for shifting topics within a document. In so doing, it provides a topic segmentation within the document and also seems to effectively distinguish among multiple senses that the same word may have in different contexts within the same document.
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.
Location Source is an implementation of Java's Location API (JSR-179). It is intended to give Java applications access to location data on platforms that do not have a JSR-179 implementation of their own. It currently only runs on Windows Mobile using IBM's WebSphere Everyplace Micro Edition (WEME) 6.1.1 bu can easily be extended to run on other platforms. For example, you could use it on any laptop by tying it into SkyHook's Loci API.
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.
