SOA support in J2EE Platform overview Primitive SOA support Support for service-orientation principles Contemporary SOA support

Platform overview

Key Java specifications Java 2 Platform Enterprise Edition Spec Java API for XML-based RPC (JAX-RPC) Web Services for J2EE

Architecture components Java Server Pages (JSPs) Struts Java Servlets Enterprise JavaBeans (EJBs)

Runtime environments EJB container Web container

Programming languages Java Various development tools

APIs Java API for XML Processing (JAXP) Java API for XML-based RPC (JAX- RPC)

Service providers JAX-RPC Service Endpoint EJB Service Endpoint Port Component Model – Service Endpoint Interface (SEI) – Service Implementation Bean

Service requestors Generated stub Dynamic proxy and dynamic invocation interface

Service agents Tasks Handlers

Platform extensions IBM Emerging Technologies Toolkit Java Web Services Developer Pack

Primitive SOA support Service encapsulation Loose coupling Messaging

Support for service-orientation principles Autonomy Reusability Statelessness Discoverability

Contemporary SOA support Based on open standards Supports vendor diversity Intrinsically interoperable Promotes federation Architecturally composable Extensibility Supports service- oriented business modeling Logic-level abstraction Organizational agility and enterprise-wide loose coupling
