You can create a Java Page Flow application in BEA WebLogic Workshop that utilizes a Service control generated from a Web service. This article uses the example of an external Web service listed on the XMethods.net site. We will import the WSDL for the Web service into BEA WebLogic Workshop and see the custom Service control that is generated. We will then consume this control within a simple Page Flow application. We can also create a sample JWS file that allows you to quickly test the control. Getting the WSDL File from XMethods.net Visit the XMethods.net site. It lists a number ... (more)
