<<As open-source development expands and SOA gains traction, many more developers are looking to open-source middleware to expedite their development of increasingly complex applications. Those apps consist of diverse components and are aimed at facilitating the deployment of distributed apps across a variety of messaging infrastructures.
The open-source community, which has focused on development tools (such as Eclipse) for several years, finally has turned its attention to the middleware problem. Products such as Mule, which have quietly chugged along for several years, are finally attracting widespread attention. New middleware products including ServiceMix and ObjectWeb also are gaining traction. Most recently, a consortium of proprietary middleware product vendors launched the Synapse initiative to create open-source middleware for SOA development and deployment. "Synapse is important because SOA is very complicated," says Robin Bloor, an analyst at Hurwitz and Associates, an IT research firm. "With SOA, you are trying to link a lot of heterogeneous stuff. Synapse will allow this to happen on the middleware level." Until this recent flurry of activity, however, middleware for the open-source community mainly meant application servers, and open- source application servers usually meant JBoss. Today there are more open-source applications servers, such as JOnAS and ObjectWeb, although JBoss still dominates. Open-source application server At the base of any middleware stack, open source or proprietary, is the application server. An application server is considered middleware because its job is to connect things, particularly an application to its various clients. To do this, the application server makes transparent as much of the infrastructure as possible. With an application server in place, developers don't have to worry about differences in operating systems, backend databases and the host of other interfaces that would bog them down in myriad nitty- gritty details.>> You can read all about it at: http://www.adtmag.com/article.asp?id=12002 Gervas ------------------------ Yahoo!
