调用webservice出现InvocationTargetException

[cici_qaz]

问题描述：
自己写了一个webservice的接口，其中有方法去调用其他已经发布的webservice。
自己写的接口一开始都测试过没有问题，但是在方法里面添加逻辑，调用其他webservice的时候出现了问题。

自己写的方法如下：
public boolean isServiceAlive() throws RemoteException {
// TODO Auto-generated method stub
System.out.println("before locator");
IServiceManagerServiceLocator serviceManagerLoc = new IServiceManagerServiceLocator();
System.out.println("after locator");
IServiceManager serviceManager = null;
try {
System.out.println("before service");
serviceManager = serviceManagerLoc.getIServiceManager(new URL("http://120.88.8.52:9000/axis/services/IServiceManager"));
} catch (MalformedURLException e) {
// TODO Auto-generated catch block
e.printStackTrace();
} catch (ServiceException e) {
// TODO Auto-generated catch block
e.printStackTrace();
}
System.out.println("after service");
if(serviceManager.listServices()!=null)
{
System.out.println("The ServiceManager is running well!!!");
return true;
}
else
{
System.out.println("The ServiceManager is crashed!!!");
reStart("ServiceManager");
return false;
}
}
用打印语句定位错误，调用的时候，打印了IServiceManagerServiceLocator serviceManagerLoc = new IServiceManagerServiceLocator();之前的“before locator”但是后面的一句没有打印，所以错误应该就是这一句。
错误信息如下：

在网上也搜了很多关于这个错误的回答，有的说是因为缺少jar包，然后我把项目用到的jar包全都放到axis的lib文件夹下，还是不行，希望大家帮着分析一下~

不能用new，要直接声明 private IServiceManagerServiceLocator serviceManagerLoc;然后set get方法
