INTERVIEW QUESTIONS J2EE SERVLET DETAILS

Question: Can we call destroy() method on servlets from service method?

Answer: Destroy() is a servlet life-cycle method called by servlet container to kill the instance of the servlet.

The answer to your question is "Yes". You can call destroy() from within the service(). It will do whatever logic you have in destroy() (cleanup, remove attributes, etc.) but it won't "unload" the servlet instance itself. That can only be done by the container

! According to servlet specification there is no need to call destroy method. But we can call destroy() method in our service() method, when we call destroy() method it will not destroy the servlet object.Typically it will unreferences the ServletConfig object. If our code try to use it at that time our servlet will fail. Source: CoolInterview.com
