Is it necessary to throw ServletException in either doGet() or doPost() in the servlet.

i mean like IOException should be throw if we take a PrintWriter out from response object.

Likewise when we need to throw ServletException?

If our method body is blank we dont need to throw none right?

Also what is this processRequest () in servlet when we use tomcat? its not there in Servlet specification right? because it says service() will called either doGet() or doPost() method not processRequest() ?

Thank You.

While overriding we may throw fewer or narrower checked exceptions or any unchecked exceptions.
So I think it is not necessary to declare that doGet() or doPost() throws ServletException and IOException.

by the way processRequest is nothing to do with tomcat. i guess you are a netbeans man. it is user defined method[which is uesd in side doGet or doPost]
I agree. Here's the link:
