WebService 问题


import java.net.URL;import org.codehaus.xfire.client.Client;
public class WSClient {

public static void main(String[] args) {

try{    
//注意：声明服务端的地址，这里是我自己的地址，根据个人设置改变
String serverURLStr = "http://localhost:8088/service/service/HelloInt?wsdl";
            Client client = new Client(new URL( serverURLStr ));    
   
            //invoke方法第一个参数是方法的名称，第二个调用该是方法所需的参数。
            Object[] results = client.invoke("HelloWorld", new Object[] {"Jets"}); 
            
   
            System.out.println((String) results[0]);
                
        } catch(Exception e){    
         throw new RuntimeException(e);   
        }

}

}
在网上下了个例子 
测试时报这个错:Exception in thread "main" java.lang.VerifyError: (class: org/codehaus/xfire/aegis/type/basic/ObjectType, method: writeSchema signature: (Lorg/jdom/Element;)V) Incompatible argument to function
