OK, this needs work, I took the outline file I keep in JOE (the Java Outline Editor, yay!) and put it’s OPML through a hastily generated XSLT to produce the following mess. No doubt I can now receive a volume of criticism for poor formatting.

Note: I’ve moved the list to the extended entry so it doesn’t all show up on the main page of my weblog. I’ve also fixed the first few bugs I found in the list (no doubt the first of many. I’ll keep working on the formatting and fixing bugs until it is fairly readable.

Cougaar

Cougaar has a Java-based architecture for the construction of large-scale distributed agent-based applications. It is the product of a multi-year DARPA research project into large scale agent systems and includes not only the core architecture but also a variety of demonstration, visualization and management components to simplify the development of complex, distributed applications.

Jicarilla

A compact, powerful, extensible and performant component-oriented software framework written in java, and a collection of components developed for this framework. Jicarilla utilizes and supports inversion of control, seperation of concerns, seperation of interface from implementation, contract-based programming, aspect-oriented programming and event-based programming. To get the buzzwords out of the way 😀

In readable english, Jicarilla provides a platform for developing a wide range of applications and software components. Think of Jicarilla as the glue between your classes, beans, components and/or services. Jicarilla can be used for building and glueing together a wide variety of applications. Whether you build web services, server applications, servlets, enterprise javabeans, desktop applications, or applets, Jicarilla will make it easier.

Mule

Mule is a light-weight messaging framework. It can be thought of as a highly distributable object broker that can seamlessly handle interactions with other applications using disparate technologies such as Jms, Http, Email, and Xml-Rpc.The Mule framework provides a highly scalable environment in which you can deploy your business components. Mule manages all the interactions between components transparently whether they exist in the same VM or over the internet and regardless of the underlying transport used.

Mule was designed around the Enterprise Service Bus enterprise integration pattern, which stipulates that different components or applications communicate through a common messaging bus, usually implemented using Jms or some other messaging server. Mule goes a lot further by abstracting Jms and any other transport technology away from the business objects used to receive messages from the bus.

Jestr

Jestr–pronounced like “jester”–is a Java Reflection-based library that provides an extensible framework for defining the way objects are “stringified”–that is, converted into String’s for display and logging purposes. It allows the application to define how objects are stringified just by editing a properties file. The style of stringification can be adjusted at runtime, either in a blanket fashion or just for individual classes, class hierarchies, and package hierarchies. Jestr is configurable using a properties file called jestr.properties, which models log4j.properties and should look reasonably familiar to those accustomed to Log4J.

It’s strict in that each cache enforces two limits in a very strict and predictable way.

SiteMesh

SiteMesh is a web-page layout and decoration framework and web- application integration framework to aid in creating large sites consisting of many pages for which a consistent look/feel, navigation and layout scheme is required.

Xephyrus Flume Pipeline

Flume is a component pipeline engine. It allows you to chain together multiple workers into a pipeline mechanism. The intention of Flume is that each of the workers would provide access to a different type of technology. For example, a pipeline could consist of a Jython script worker followed by a BeanShell script worker followed by an XSLT worker.

The pipeline workers can contain any custom code, however the intention behind Flume is that the workers would implement different scripting languages. This provides a means of separating distinct functionality of the work-flow. For example, if Al understands the business flow and Betty is really good at making it look good, Al could write his piece in Jelly and Betty could do her work in XSL. The pipeline could then execute Al’s script, then do Betty’s transformation, spewing out some nice document.

The JReleaseInfo AntTask generates a java source file with getter methods for the build date of the program, a build number or the version.

SwarmCache

SwarmCache is a simple but effective distributed cache. It uses IP multicast to efficiently communicate with any number of hosts on a LAN. It is specifically designed for use by clustered, database-driven web applications. Such applications typically have many more read operations than write operations, which allows SwarmCache to deliver the greatest performance gains. SwarmCache uses JavaGroups internally to manage the membership and communications of its distributed cache.

Element Construction Set

The Element Construction Set makes it easy for you to build structured XML from a series of calls to objects. It tries to make sure you can’t generate something that is not well-formed at the least, even if it is not necessarily well structured. I’ve used this in the past and found it easy to use but it seems to have fallen from favor. The last time I looked there wasn’t much new activity and most people I work with tend to push for using JDOM for this purpose.

VMTools

Library functions to find differences between XML documents and represent those differences as a series of edit operations (again in XML form). Sample code is provided to make it easy to not only find the differences but also to patch an existing file to make it look like a new one.

OpenEmcee

The “OpenEmcee Microflow Engine for Java” is an open source framework (Released under MPL 1.1) for developing flexible, manageable, and adaptable applications. It aims to allow application developers to develop well-engineered business-logic intensive application domain software. Drafting from the “Model” and “Controller” layers of the “Model-View-Controller” pattern, it allows developers to separate the business context of their application from their core business functions.

This separation of context from core implementation encourages development of software units which are easily reusable and require no or little modification to business critical code when implementing new functionality. Also, these units of work (“tasks”) can be easily reused in future projects.
