Success Stories

Projects using Javagroups:


Project	Description
JBoss (www.jboss.org )	Clustering of Enterprise Java Beans We use JavaGroups as the underlying framework for implementing the clustering features of the JBoss J2EE Application server. JavaGroups gave us the opportunity to concentrate our efforts on the clustering features of JBoss instead of the very complex aspects of reliable group communication protocols. Through a very flexible and esthaetic API we were able to built our clustering features without making strong assumption about the underlying protocols and network scheme (LAN, WAN, ...) that the end-users would face. As JavaGroups is an LGPL Open Source Project (which JBoss, as an open source project, requires), we were able to quickly find some minor bugs and implement new features that fitted our needs. Furthermore, thanks to Bela Ban recognized strong competencies in this arena and its growing user community, JavaGroups is a very dynamic project. Sacha Labourey (co-developer of JBoss clustering)
Jtrix (www.jtrix.org )	Adaptive, scalable, distributed applications. Jtrix is all about creating distributed applications which can move themselves around and find their best home. By using JavaGroups we are able to cluster Jtrix nodes. Several servers can cluster together to present a unified runtime environment, which is actually physically split up over several machines. JavaGroups handles communication between the nodes. By virtue of its maturity, modular design and comprehensive documentation we were able to add clustering at a fraction of the effort it would have taken to create our own system, which would have been significant.
GroupPac (http://grouppac.sourceforge.net)	GroupPac is a open source implementation of the Fault-Tolerant CORBA specification. Because of the complexity of implementing reliable multicast group communication, GroupPac was limited to passive replication. By using JavaGroups, we were enabled to redirect our efforts to others equally important aspect of the FT-CORBA specification, such as scalability and group communication tool support. Because of the time and effort spared by JavaGroups, GroupPac now offers active replication through a simple, elegant way of plugging in any group communication tool. Of course, the only supported group communication tool is JavaGroups! Ricardo S. Padilha (analyst and developer of GroupPac)
