Hi All,
I remember that in many
J2EE applications, we have a web server, app server and DB call finally.
I have a set of questions here...
1. Why do we need 2 servers on the first hand?
2. What is the difference between a web server and an app server?
3. What is the exact flow of request and response in such a case?
4. Where is the WAR deployed and where is the EAR deployed (in web server or appserver)?
It will be of great help if somebody can give be a step by step explanation of these 4 questions.
Thanks.
Regards,
Ram
