Xfire~~传递对象的问题~~
最近在看WebService，由于要整合Spring，所以选择了Xfire。
服务器端和客户端的测试demo都写好了。
当传递的参数是String类型的时候，没什么问题。
当传递的参数是自定义的User对象的时候，出现异常：
Exception in thread "main" org.codehaus.xfire.fault.XFireFault: Fault: java.lang.NullPointerException

此时的WSDL用IE能访问到。
DEBUG跟踪客户端进去，发现他根本没进入WebService暴露出的addUser方法就报错了。
User类我序列化过了，请问有人遇到过这类问题么，有解决方案么？？
User类：
- Java code
public class User implements Serializable{ private static final long serialVersionUID = 5502216907549201191L; public User(){}; public User(String name,String password){ this.name = name; this.password = password; } private int id; private String name; private String password; public int getId() { return id; } public void setId(int id) { this.id = id; } public String getName() { return name; } public void setName(String name) { this.name = name; } public String getPassword() { return password; } public void setPassword(String password) { this.password = password; }}UserDao接口：
- Java code
public interface UserDao { public User findUserById(int id); public List<User> findAllUsers(); public boolean addUser(User user); public boolean updateUser(User user); public boolean deleteUser(User user);}UserDaoImpl实现类：
- Java code
public class UserDaoImpl extends HibernateDaoSupport implements UserDao { public boolean deleteUser(User user) { this.getHibernateTemplate().delete(user); return true; } public List<User> findAllUsers() { List<User> users = this.getHibernateTemplate().find("from User"); return users; } public User findUserById(int id) { User user = (User) this.getHibernateTemplate().get(User.class, id); return user; } public boolean addUser(User user) {System.out.println(user.getName());System.out.println(user.getPassword()); this.getHibernateTemplate().save(user); return true; } public boolean updateUser(User user) { this.getHibernateTemplate().update(user); return true; }}
UserText测试类：
- Java code
public class UserText { public static void main(String[] args) throws MalformedURLException, Exception { Client client = new Client(new URL( "http://localhost:8080/xfire/services/UserDao?wsdl")); Object[] opAddEntryArgs = new Object[] {new User("zhangzhibo","zhangzhibo")}; Object[] results = client .invoke("addUser", opAddEntryArgs); System.out.println(results[0]);}applicationContext.xml，xfire-servlet.xml，Web.xml个人猜测没什么错误，因为测试的时候传String都可以调用。
如果有需要，后面贴上来。
请知道的朋友赐教~~谢谢
[解决办法]
配置文件贴出来吧。。
建议先把 this.getHibernateTemplate().save(user); 注释掉。看看效果。
或者

好长，配置这些东东最烦了
