| <div><p>Web services can be created using two methods: top-down development |
| and bottom-up development. Top-down Web services development involves creating |
| a Web service from a WSDL file.</p> |
| <p>Although bottom-up Web service development may be faster and easier, especially |
| if you are new to Web services, the top-down approach is the recommended way |
| of creating a Web service.</p> |
| <p>When creating a Web service using a top-down approach, first you design |
| the implementation of the Web service by creating a WSDL file. You can do |
| this using the WSDL Editor. You can then use the Web services wizard to create |
| the Web service and skeleton Java™ classes to which you can add the required |
| code.</p> |
