为什么 Service service= new Service();

Question

package com.util;

import java.net.MalformedURLException;
import java.net.URL;
import java.rmi.RemoteException;

import javax.xml.rpc.ServiceException;

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

public class WebServiceClient {
public static String test(String key,String jsonMsg,String endpoint,String orgid,String type) throws ServiceException, MalformedURLException, RemoteException {

    try {
        Service service = new Service();
        Call call = (Call) service.createCall();
        call.setTargetEndpointAddress(new URL(endpoint));
        call.setOperationName("revInsuranceData");
        call.setUseSOAPAction(true);

        String res = (String) call.invoke(new Object[] { id1,type });
        decryptStr = eu.getDecryptStr(key, res);
        System.out.println(decryptStr);
    } catch (Exception e) {
        // TODO Auto-generated catch block
        e.printStackTrace();
    }
    return decryptStr;
}
public static void main(String[] args) throws Exception {
    test( key, jsonMsg, endpoint, orgid, type);
}

}

使用main测试的时候是没有问题的，当放在tomact下，通过方法调用，就会在Service service = new Service()处卡主，使用try/catch捕获异常，会看到java.lang.reflect.InvocationTargetException，但在控制台并不输出这个错误，各个jar包均已经导入，很迷茫呢。等待着大神。

因为Service是一个类
