导读：注释是自己的理解。。 package com.jielan.axis2; import org.apache.axiom.om.OMAbstractFactory; import org.apache.axiom.om.OMElement; import org.apache.axiom.om.OMFactory; import org.apache.axiom.om.OMNamespace; import org.apache.axis2.AxisF

注释是自己的理解。。

package com.jielan.axis2;

?? ?}

?? ?public static OMElement getWeather(String action,String methodStr,String[] vals){

?? ??? ?try {

?? ??? ?return result;

?? ?}

??public static void main(String[] args) {
?? ??? ?String action? = "http://WebXml.com.cn/getWeatherbyCityName";
?? ??? ?String methodStr = "getWeatherbyCityName";
?? ??? ?String namespace = "http://WebXml.com.cn/";
?? ??? ?String tns = "xsd";
?? ??? ?String[] pars = {"theCityName"};

?? ??? ?OMElement result = null;
?? ??? ?result = getWeather(action,methodStr,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 :
