Planning to use Web services based on Web Services for J2EE

This topic discusses how to plan your use of Web services that are developed and implemented based on the Web Services for Java 2, Enterprise Edition (J2EE) specification.

Read the Web services scenario... Overview which tells the story of a fictional online garden supply retailer named Plants by WebSphere and how they incorporated the Web services concept.

To plan to use Web services based on Web Services for J2EE...

1. Design Web services to fit your e-business solution.Consider what you want to accomplish by using Web services, how Web services fit into your current topology, applications and programming model. Decide how the Web services will process requests on the server and how the clients will manage and use the Web service.

   Design your Web services for reliability, availability, manageability and security. For example, you want your Web services to process a transaction in a reasonable time at all hours of the day and provide users with good security characteristics, such as authentication for buyers. Planning to use Web services to work with WAS helps to meet these requirements.

   To support Web services, extend WebSphere Application Server to support Web services standards. For interoperable Web services running on platforms supplied by multiple vendors, standards are essential. WAS uses Web services standards developed for the Java language under the Java Community Process (JCP). These standards include the Web Services for J2EE and JAX-RPC specifications.

2. Decide what development and implementation tools to use. Use a variety of manual development and implementation tasks. Whether you have an existing Web service to implement or you want to develop your own from a Java bean or enterprise JavaBean (EJB), you can choose different tasks respective to your resources. You can also use the WebSphere Studio Application Developer to complete development and implementation tasks.

   See Developing Web services based on Web Services for J2EE for information about developing Web services based on the Java language through WAS. To read more about the WebSphere Studio Application Developer see the WebSphere Studio Application Developer information center.

3. Install WebSphere Application Server.

4. Review Web services Samples.
