Web Services Code Samples

Web services are web-based services that are accessed by business application programs. The service receives the request for its services and returns a response. The Java programming language provides a number of APIs for writing web service applications.

• Getting Started
• Registration and Discovery
• Java Web Services Developer Pack
• JAX-RPC
• Performance

• Getting Started Application download from the Java Series book The Java Web Services Tutorial.
• HelloClient.java is a remote client that contacts a web service and invokes the sayHello method. HelloIF.java is the service definition interface, and HelloImpl.java is the impl ementation interface for the HelloIF class. For more information see The Java Web Services Tutorial: Java API for XML-based RPC.
• HelloClient.java makes two remote procedure calls. For more information see The Java Web Services Tutorial: Java API for XML-based RPC.

JAX-RPC

• Request.java sends a request-response message to a web service. For more information see The Java Web Services Tutorial: Java API for XML Messaging.
• SunRegImpl.java hows the service implementation class for SunRegPort. For more information see Getting Started with JAX-RPC.
• SunRegPort.java shows code for the service endpoint interface for SunReg. For more information see Getting Started with JAX-RPC.

• MyUddiPing.java accesses a test version of a UDDI service registry. A Universal Description, Discovery, and Integration (UDDI) service is a business registry and repository from which you can get information about businesses that have registered themselves with the registry. For more information see The Java Web Services Tutorial: Java API for XML Messaging.
• NaicsQuery.java hows how to perform queries programmatically. For more information see Registration and Discovery of Web Services Using JAXR with XML Registries such as UDDI and ebXML.
• PublishORG.java shows how to create an organization and publish it in the IBM UDDI V2 Business Registry. For more information see Registration and Discovery of Web Services Using JAXR with XML Registries such as UDDI and ebXML.
