新手请教：java调用webservice报错

Question

我用Axis调用webservice ,报出这样一个错误： faultString: 服务器无法处理请求。 ---> 未将对象引用设置到对象的实例。
详细错误如下：
Exception in thread "main" AxisFault
 faultCode: {http://schemas.xmlsoap.org/soap/envelope/}Server
 faultSubcode: 
 faultString: 服务器无法处理请求。 ---> 未将对象引用设置到对象的实例。
 faultActor: 
 faultNode: 
 faultDetail: 
{http://xml.apache.org/axis/}stackTrace:服务器无法处理请求。 ---> 未将对象引用设置到对象的实例。

一定要设置Action.否则服务器无法处理请求,不知道你引用的是哪个方法,所以报出未将对象引用设置到对象的实例

Answer 2

call.setTargetEndpointAddress(new java.net.URL("服务地址"));
call.setOperationName(new QName("命名空间","服务名称"));

Answer 3

try{String endPoint = "http://202.102.36.242:8080/CSB/services/ImsService";
Service service = new Service();
Call call = (Call)service.createCall();
call.setTargetEndpointAddress(new java.net.URL(endPoint));
call.setOperationName(new 
QName("http://com.linkage.ims","GET_IMS_USER_INFO"));
String res = (String)call.invoke(new Object[]{"512","68284124"});
System.out.println("入参：512，68284124, 返回结果：res"+res);
}catch(Exception e){
System.out.println("出错："+e.toString());
e.printStackTrace();
}用这个 试试
