How can you share data between Servlets?

Question

Aryan Kumar · Answer

Sharing data between servlets is like passing notes between friends. In the world of servlets, there are several ways to achieve this:
Servlet Collaboration - RequestDispatcher:
One servlet can forward a request to another servlet using RequestDispatcher. It's like passing the note to a friend and asking them to handle part of the task.
Using ServletContext:
The ServletContext is like a common bulletin board for all servlets. One servlet can set an attribute, and another servlet can retrieve it.
URL Rewriting:
Data can be passed between servlets through URL parameters. It's like including a note in the URL for the other servlet to read.
Session Objects:
Data can be stored in a session, and any servlet within the same session can access it. It's like passing a note that stays with a friend throughout the conversation.
These are different ways to share data between servlets, each with its own use case. Choose the method that fits the requirements of your application.
