在自己的工程里发布webservice的步骤(2)

namespace=\http://DefaultNamespace\ use=\encoded\

-

encodingStyle=\http://schemas.xmlsoap.org/soap/encoding/\

encodingStyle=\http://schemas.xmlsoap.org/soap/encoding/\

namespace=\http://127.0.0.1:8080/MyWebServices/services/SayHello\ use=\encoded\

-

-

location=\http://127.0.0.1:8080/MyWebServices/services/SayHello\

说明：wsdl中描述了该webservices的方法为：hello，输入参数为name，String类型，返回参数为String类型，调用方式为rpc，和我们之前在wsdd中配置的一样。

看完说明我们可以直接在浏览器中调用该webservices： 在浏览器中输入：

http://127.0.0.1:8080/MyWebServices/services/SayHello?method=hello&name=waiwai 你会看到：

xmlns:soapenv=\http://schemas.xmlsoap.org/soap/envelope/\ xmlns:xsd=\http://www.w3.org/2001/XMLSchema\

xmlns:xsi=\http://www.w3.org/2001/XMLSchema-instance\ - -

soapenv:encodingStyle=\http://schemas.xmlsoap.org/soap/encoding/\

好,waiwai, axis Ver1.4 欢迎你.

xsi:type=\soapenc:string\

你

xmlns:soapenc=\http://schemas.xmlsoap.org/soap/encoding/\

我们可以看到浏览器返回的是一String类型数据：你好,waiwai, axis Ver1.4 欢迎你.

7. 接下来我们使用外部项目调用该webservices：

创建新的项目CallWebServices，同样引入axis的8个jar包，创建调用webservices的类

示例代码：

import javax.xml.namespace.QName;

import org.apache.axis.client.Call; import org.apache.axis.client.Service;

public class CallSayHello { ;

//设置获取响应参数的格式

//call.setUseSOAPAction(true);

//call.setSOAPActionURI(\

String result = (String)call.invoke(new Object[]{\}); //调用Webservice

System.out.println(\+result); }

//call.setReturnType(org.apache.axis.encoding.XMLType.XSD_STRING)public static void main(String[] args) {

try {

String endpoint =

//webservices的wsdl的url地址

Service service = new Service(); //创建服务

Call call = (Call) service.createCall(); //创建调用

call.setTargetEndpointAddress(endpoint); //设置调用的url地址

//call.setOperationName(\

call.setOperationName(new QName(\)); //设置调用的方法(method)

\;

}

}

catch (Exception e) {

System.err.println(e.toString()); }

执行该程序：后台输出：

result is :你好,waiwai, axis Ver1.4 欢迎你. 这表示webservices调用成功。

8. 实际应用中webservices的例子

调用天气预报的webservices：

import java.io.IOException; import java.io.InputStream;

import java.io.UnsupportedEncodingException; import java.net.MalformedURLException; import java.net.URL;

import java.net.URLConnection; import java.util.ArrayList; import java.util.List;

import javax.xml.parsers.DocumentBuilder;

import javax.xml.parsers.DocumentBuilderFactory; import javax.xml.parsers.ParserConfigurationException;

import org.w3c.dom.DOMException; import org.w3c.dom.Document; import org.w3c.dom.Node; import org.w3c.dom.NodeList; import org.xml.sax.SAXException;
