Answer 2

org.codehaus.xfire.fault.XFireFault: Fault: java.lang.NullPointerException
空指针异常，你看看这个XFireFault是哪里空了

Answer 3

 服务端测试:public static void main(String[] args) {
ApplicationContext context = new FileSystemXmlApplicationContext(
"/WebRoot/WEB-INF/applicationContext.xml");
CheckLoginImpl login = (CheckLoginImpl)context.getBean("sysTest");
System.out.println(login.myTest());
}测试是有数据的;如果不用hibernate 的方法,调用可以,用hibernate 的方法就不行;执行:FlSysSet flsysSet = sysSetDao.findById(1);
或是findAll(); 这儿就错了!!
