This topic discusses how to plan your use of Web services that are developed and implemented based on the Web Services for Java 2 Platform, Enterprise Edition (J2EE) specification.
Before you begin
Read the Web services scenario: Overview which tells the story of a fictional online garden supply retailer named Plants by WebSphere and how this retailer incorporated the Web services concept.Why and when to perform this task
Web services are Web applications that help you be more flexible in your business processes by integrating with applications that otherwise do not communicate.
Web services reflect the service-oriented architecture approach to programming. This approach is based on the idea of building applications by discovering and implementing network-available services, or by invoking the available applications to accomplish a task. Web services deliver interoperability, for example, Web services applications provide a way for components created in different programming languages to work together as if they were created using the same language. Web services rely on existing transport technologies, such as HTTP, and standard data encoding techniques, such as Extensible Markup Language (XML), for invoking the implementation.
To plan to use Web services:
Steps for this task
See Developing Web services for information about developing Web services based on the Java language through the WebSphere Application Server. To read more about RAD see the information center for the product.
Result
You have a design plan for implementing Web services applications into your business architecture.What to do next
