Best practices for developing enterprise beans

Use these guidelines when designing and developing enterprise beans

:

• Use a stateless session bean to act as the entry point for business logic.
• Entity beans should use container-managed persistence.
• In an Enterprise JavaBeans (EJB) Version 2.0 environment, use local interfaces to improve communication between enterprise beans in the same Java virtual machine. Local calls avoid the overhead of RMI/IIOP and use pass-by-reference semantics instead of pass-by-value. For each call, the caller and callee beans share the state of arguments. EJB 2.0 beans can have both a local and remote interface but more typically have one or the other.
• For communicating with remote clients, provide remote and remote home interfaces. For communicating with local clients like servlets, entity beans, and message-driven beans, provide local and local home interfaces.
