本人刚刚自学了dwr,按照网上的讲解测试了dwr返回值为javabean,list,map,String[],String都没问题，但是在测试带javabean参数的时候出问题了，老是返回Error,为此又看了很多视频讲解，但是始终没找到问题所在，百度百科上的讲解也是和我写的一样，求各位大神指点，下面是代码
java代码
public class dwrtest {
public String test3(User user){
return user.getUser();
}
}
User.java
public class User {
private String user;
private String password;
public User(String user, String password) {
super();
this.user = user;
this.password = password;
}
public String getUser() {
return user;
}
public void setUser(String user) {
this.user = user;
}
public String getPassword() {
return password;
}
public void setPassword(String password) {
this.password = password;
}
}
