Doubt on Servlets

[janardhan rao B]

hi, this is janardhan and i am a junior java developer.
can any one please give me answer for the below...
what is the purpose of destroy( ) method , when it will call, who will call and what are the cases or reasons for calling this method in a servlet ?

[William Brogden]

The servlet container calls the destroy method when it is about to take the servlet out of service.

Just like it says in the javax.servlet.destroy() documentation. If the programmer has created some resource that should be cleaned up - for example flushing and closing a file, this is your last chance to do it.

When this point is covered is all discussions of the servlet life cycle, why did you find it necessary to ask here?
