Difference between Stateful and Stateless Session Beans in Java EE

In Java EE, Stateful and Stateless Session Beans are two types of session beans that serve different purposes in the enterprise application development.

Stateful Session Beans:

• Stateful Session Beans maintain conversational state with the client throughout multiple method calls.
• Each client is assigned a unique instance of a Stateful Session Bean, keeping track of its state between method invocations.
• Stateful Session Beans are suitable for use cases where the state of the client needs to be maintained across multiple interactions.

Stateless Session Beans:

• Stateless Session Beans do not maintain any client-specific state between method calls.
• Each method call to a Stateless Session Bean is independent of previous method calls, making them more scalable and efficient.
• Stateless Session Beans are suitable for use cases where the client's state is not required to be maintained between interactions.

It is important to choose between Stateful and Stateless Session Beans based on the specific requirements of the application to ensure optimal performance and scalability.
