JEFF is an explanation facility framework written in Java. Explanation facilities date from the era of expert systems (ES), where they were used in order to provide an explanation about the inference process. The explanation they provided was supposed to clarify how the ES reached its conclusions or why it asked some question during fact acquisition. Nowadays, traditional ES development environments ("shells") have been replaced by rule engines (RE) and business rule management systems (BRMS), which seem to lack explanation facility functionality. JEFF was created in order to remedy this.
JQuery BarGauge is a jQuery plugin that displays an animated progress gauge bar. It can show a progress bar inside an HTML page container element with a given width and height. The number value of the current position can be displayed with the progress bar formatted with a configurable number of decimal places.
JS-Collider is an event-driven Java network NIO framework. It is designed to provide maximum performance and scalability for applications having not too many connections but significant amounts of network traffic (both incoming and outgoing). Performance and scalability are achieved via lock free algorithms and atomic states usage. It supports UDP (with multicast) as well. One of the implementation points is to avoid unsafe cheating; it should work the same way on all JVMs (Java 1.7). It supports shared memory IPC.
Jat (Java Application Template) is a Java framework that is easy to extend. It supplies modular and flexible basic functionalities to develop Web and standalone applications. It can improve application start-up time. Jat Portal is an enhanced version of Jat. It provides several pre-configured features to build a complete Web application.
Java Gearman Service is a Java implementation of the gearman service, which provides a generic application framework that farms work out to other machines or processes that are better suited to do the work. It allows you to do work in parallel, to load balance processing, and to call functions in other languages. It can be used in a variety of applications, from high-availability Web sites to the transport of database replication events.
Unlike other Java to Objective-C solutions, Java-Objective-C Bridge doesn't require any code generation of class stubs. It allows you to use any Objective-C libraries and frameworks from Java without having to write any native code. In addition to being able to use Objective-C objects, it allows you to pass Java objects to the objective-c runtime as delegates, so that you can write an entire Cocoa application in Java. The bridge provides 3 levels of abstraction. At the lowest level, it provides wrappers around the Objective-C runtime functions. At a slightly higher level of abstraction, it provides a procedural API to send messages to the Objective-C runtime. At the highest level of abstraction, it provides a Proxy class that serves as a wrapper around any Objective-C object that allows you to work with it in Java almost the same as if you were in Objective-C.
