Description: The Java 2 Platform, Enterprise Edition (J2EE) version 1.4 has evolved to integrate web services. Web services are now one of the many service delivery channels of the J2EE platform; existing J2EE components can be easily exposed as web services. Many benefits of the J2EE platform are available for web services, including portability, scalability, reliability, and no single-vendor lock-in. For example, J2EE containers provide transaction support, database connections, life cycle management, and other services that are scalable and require no code from application developers.
