Difference between Container and Server

[Mitesh Khapra]

Hi,
I had posted this earlier but did not get any reply so am posting it again. Somebody please help!!!
I was reading the second chapter of "HF-Serlets and JSP" and came across the terms "container" and "server". Till now my understanding was that a server itself controls the life cycle of a servlet. But here it is mentioned that the life cycle is controlled by a container. Can somebody please clear the following doubts related to container and server:-

1. Do they run in the same JVM or different JVM
2. Can somebody please tell me what is a "container" and what is a "server" in the context of IBM's Websphere.

Thanks and Regards,
Mitesh.

my understanding is that the container is more of a concept. servlets run in a servlet container, and no real documentation should be mentioning a server. a server is, in a way, an implementation of a container, although a server could do much more.
