Using HTTP to transport web services
You can develop an HTTP accessible web service when you have an existing JavaBeans object to enable as a web service.
Before you begin
Develop a Web Services Description Language (WSDL) file. You need a WSDL file to use web services. You can develop your own WSDL file or get one from a web services provider through email, downloading, or through a Uniform Resource Locator (URL). This documentation assumes you are creating your own.
About this task
The application server supports the use of HTTP to transport web services client requests. With HTTP, your web services clients and servers can communicate through SOAP messages. SOAP is the underlying communication protocol that is used in web services that support the Web Services for Java™ Platform, Enterprise Edition (Java EE), the Java API for XML-Based Web Services (JAX-WS), and the Java API for XML-based remote procedure call (JAX-RPC) specifications.
HTTP is the most commonly used transport for web services.
