Message-Driven Beans (MDB) and Stateless Session Beans are designed to be stateless, meaning they do not maintain any state information between method invocations or transactions. MDBs are designed to process incoming messages asynchronously, without holding any state for a specific client. Stateless Session Beans execute business logic but do not retain any client-specific state between method calls.
