# Creating bottom-up Web services

Web services can be created using two methods: top-down development and bottom-up development. Bottom-up Web services development involves creating a Web service from a Java™ bean, enterprise bean, URL, DADX file, or ISD.

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.

When creating a Web service using a bottom-up approach, first you create a Java bean or EJB bean and then use the Web services wizard to create the WSDL file and Web service.
