Hi All,<br />
<br />
Would appreciate reply on this please.<br />
<br />
I am new to Application Servers and all I know is there are couple of Application Servers available right now and most famous among those are WebLogic, WebSphere, 9iAS. As I understand, application servers are needed and used for J2EE architecture involving developing and deploying EJB components.<br />
<br />
What I want to understand is..<br />
1). While there are so many app servers available, How does a company's architect decide which one of to chose? whats the use of WebSphere over WebLogic or vice versa? How should I decide which One should I be using?<br />
<br />
2). which app servers are available in the market other than I mentioned? Do we need App Server as I understood for developing and deploying EJB components only? or is there any other purpose of app servers?<br />
<br />
would appreciate help plz<br />
<br />

Understanding Application Server --- WebLogic, WebSphere, 9iAS, OC4J and others

An application server is a software framework that provides both facilities to create applications and a server environment to run them. Most application server frameworks contain a comprehensive service layer model, acting as a set of components accessible to the software developer through an API defined by the platform itself. For Web applications, these components are usually performed in the same running environment as their web server(s), and their main job is to support the construction of dynamic pages. However, many application servers target much more than just Web page generation: they implement services like clustering, fail-over, and load-balancing.
