I just want to confim this.
clustered environment means distributed environment, having multiple web server for one application, so there will be different instance of any servlet (or any resource) on each web server.

please comments.

If it is right then, how any request goes to any particular web server?

Thanks.

Basically yes, a clustered environment is one where an application is serviced by multiple servers running in different nodes in a network. Usually there will be some type of load balancer used in front of the cluster that will direct the request to one of the servers based on current load and processing, although this isn't mandatory.

If you are looking into using a clustered environment, you might want to brush up on session migration too, so you understand the high level view of how sessions are maintained accross JVMs.
