EJB

Abstract: Just as the Java platform has revolutionized the way we think about software development, Enterprise JavaBeans promises to revolutionize the way we think about developing mission-critical enterprise software. It combines server-side components with distributed object technologies and asynchronous messaging to greatly simplify the task of application development. It automatically takes into account many of the requirements of business systems, including security, resource pooling, persistence, concurrency, and transactional integrity.
