java - same validation on multiple servlets in one application -


How to implement some arguments for example that is common to all services without writing in all servlets? As Servlets are already expanding from an abstract class, we can not create a guardian's salts and can increase the child's servlets. So how can I get similar functionality? If the answer is some filter / interceptor / framework, then can we do it without the use of any framework?

You may wish to use the sublet filter, see for details.
