Question

Under what circumstances will a servlet be reloaded?

Answer 1

Whenever a webserver receives a request from the client, and if it found it as a servlet, it redirects the request to the servlet container, the servlet container inturn sends the request to the appropriate servlet. So, the servlet gets loaded in the jvm the first times it gets request and remains there for some time, so whenever the next request comes it is readily available to serve it.
