An Open Source and cross-platform toolkit for reliable multicast communication in Java

editor's review





JGroups is an open source, completely free and multiplatform toolkit implemented in the Java programming language and designed from the ground up to act as a reliable and stable group communication solution. It can be used to implement multicast communications in your apps.

Based on configurable protocol stack and IP multicast

The software is based on configurable protocol stack and IP multicast. It features reliable multicasting support, as well as high speed messaging support. In addition, JGroups is easily adaptable and cloud enabled. It can be used by application developers to easily create multipoint (multicast) Java apps, saving them a lot of time.

Getting started with JGroups

The project is distributed as a pre-built binary package in the JAR file format, which can be simply add to your classpath. That’s it, you can now start coding. Please note that the source code is also distributed as a JAR file.

If you open a Terminal app in the folder where you’ve save the binary package, you can view the JGroups version by running the ‘java -jar jgroups-x.y.z.jar’ command, where x.y.z is the current version number of the project (e.g. java -jar jgroups-3.6.1.jar).

To test JGroups, run a simple draw demo by starting two or more instances with the ‘java -cp jgroups-x.y.z.jar org.jgroups.demos.Draw’ command (don’t forget to replace x.y.z with the current version number of the program) and see if the members find each other.

Runs on any computer operating system supported by Java

JGroups is a cross-platform application that will run on any computer operating system supported by Java, including Linux, Microsoft Windows, and Mac OS X. It requires the Java Runtime Executable (JRE) to work. Both 32 and 64-bit hardware platforms are supported.
