axis2通过城市名称调用.net写的asmx WebService查询天气实例

注释是自己的理解。。

    private static OMFactory fac = OMAbstractFactory.getOMFactory();

    public static OMElement getOMMethod(String methodStr,String namespace,String tns,String[] pars,String[] vals){
        //创建命名空间

        String tns = "xsd";
        String[] pars = {"theCityName"};
        String[] vals = {"杭州"};
        OMElement result = null;
        result = getWeather(action, methodStr, namespace, tns, pars, vals);
        System.out.println(result);
    }

}

查看namespace

查看端点引用指接口位置接口地址

查看调用方法名和 soapAction的action地址

另外OMElement method = fac.createOMElement(methodStr, nms);第二个参数nms 具体是什么好像随便填，""也行

不过查了很多看到有人说这是服务名。。

这里只要不填已有的变量名，遇到变量重复定义错误，就都可以。。

结果:

index.jsp上调用

<body>
    <%
        //out.print(InvokeExercise.invokeWucan().replaceAll("</string>", "</string>\r<br/>"));
          //out.print(InvokeExercise.invokeYouCan());
          out.print(Client01.getWeather(
                  "http://WebXml.com.cn/getWeatherbyCityName",
                  "getWeatherbyCityName","http://WebXml.com.cn/",
                  "xsd",new String[]{"theCityName"},
                  new String[]{"台州"}).toString().replaceAll("。", "。<br/>").replaceAll("今日天气实况", "<br/>今日天气实况"));
    %>
</body>

web上调用结果 :

补充：Web开发 , ASP.Net ,
