I. Creation of the WSDL webservice: 1. Create "Web Service Project": WebServices Framework to choose Jax-ws: 2. Write a simple test case: <pre name="code" class="java" style="font-size:12px; "><pre name="code" class="java" style="font-size:12px; ">Package Com.webservice;public class Webservice{public string printdata (string printername) {string strret = ' Welcome to us E WebService, "+ printername; System.out.println ("Print from WebService:" + strret); return strret;}}</pre></pre> 3. Publish the web Service: Click New Web Service on the toolbar: Strategy Select a second (Create Web service from Java class): tick "Generate WSDL in project": after clicking "Finish", the system will generate two files under Web-inf/wsdl: webserviceservice.wsdl: This file is used to describe the Web service content <pre name="code" class="html" style="font-size:12px; "><?xml version= "1.0" encoding= "UTF-8"?><definitions xmlns= "http://schemas.xmlsoap.org/wsdl/" xmlns:soap= "http://schemas.xmlsoap.org/wsdl/soap/ "xmlns:tns=" http://webservice.com/"xmlns:wsu=" http://docs.oasis-open.org/wss/2004/01/ Oasis-200401-wss-wssecurity-utility-1.0.xsd "xmlns:xsd=" Http://www.w3.org/2001/XMLSchema "name=" Webserviceservice "targetnamespace=" http://webservice.com/"> <types> <xsd:schema> <xsd:import N amespace= "http://webservice.com/" schemalocation= "webserviceservice_schema1.xsd"/> </xsd:schema> </ types> <message name= "printdata" > <part element= "tns:printdata" name= "parameters"/> </message> <message name= "printdataresponse" > <part element= "tns:printdataresponse" name= "parameters"/> </ message> <porttype name= "webservicedelegate" > <operation name= "PRIntdata "> <input message=" tns:printdata "/> <output message=" tns:printdataresponse "/> </oper ation> </portType> <binding name= "webserviceportbinding" type= "tns:webservicedelegate" > <soap: Binding style= "document" transport= "http://schemas.xmlsoap.org/soap/http"/> <operation name= "printdata" > <soap:operation soapaction= ""/> <input> <soap:body use= "literal"/> </input> <output> <soap:body use= "literal"/> </output> </operation> </binding> <s Ervice name= "webserviceservice" > <port binding= "tns:webserviceportbinding" name= "webserviceport" > <soa P:address location= "http://localhost:8080/WebService/WebServicePort"/> </port> </service></ Definitions></pre> webserviceservice_schema1.xsd: commands and their parameters used to describe a Web service for Example: The WebService in sample is "printdata", has a string type parameter "arg0", returns a value of a string type. <pre name="code" class="html" style="font-size:12px; "><pre name="code" class="html" style="font-size:12px; "><?xml version= "1.0" encoding= "UTF-8"? ><xs:schema xmlns:xs= "http://www.w3.org/2001/XMLSchema" xmlns:tns= " http://webservice.com/"targetnamespace=" http://webservice.com/"version=" 1.0 "> <xs:element name=" Printdata "type=" tns:printdata "/> <xs:element name=" printdataresponse "type=" tns:printdataresponse "/ > <xs:complextype name= "printdata" > <xs:sequence> <xs:element minoccurs= "0" name= " arg0 "type=" xs:string "/> </xs:sequence> </xs:complexType> <xs:complextype name=" Printdataresponse "> <xs:sequence> <xs:element minoccurs=" 0 "name=" return "type=" xs:string "/ > </xs:sequence> </xs:complexType></xs:schema></pre></pre> Deploy the WebService project to Tomcat. ( deployment method slightly ) two. Invocation of WSDL webservice: Method 1: Create a Web Service client to Invoke: 1. Create "Java Project": 2.Click the new Web Service Client on the toolbar: 3. Select "WSDL URL": 4. After clicking "next" to complete the creation, the relevant files are automatically generated under Src/com/webservice. (except webservicetest.java, This is a call file created by Itself) 5. Create "webservicetest.java" The code is as Follows: <pre name="code" class="java"><pre name="code" class="java">Package Com.webservice;public class Webservicetest{public static void main (string[] Args) {webserviceservice Wssprintdata = new Webserviceservice (); Webservicedelegate Wsdprintdata = Wssprintdata.getwebserviceport (); System.out.println (wsdprintdata.printdata ("sun"));}}</pre></pre> 6.
