求教关于dwr客户端获取服务端返回对象为null的问题，郁闷了一天了~！~！

			<include method="getUser"/>
		</create>
		<convert match="bean" converter="org.li.dwr.User"></convert>
	</allow>
</dwr>

dwr.xml的内容

public class User {
	private String name;
	private String password;
	private int age;
	public int getAge() {
		return age;
	}
	public void setAge(int age) {
		this.age = age;
	}
	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;
	}
}

User类

public class TestUser {
	public User getUser(){
		User u = new User();
		u.setAge(20);
		u.setName("testuser");
		u.setPassword("123456");
		return u;
	}
}

测试getUser方法

function juserbutton() 
 {
 	alert("11");
 	jsuser.getUser(callbackUser);
 }
 function　callbackUser(msg)
 {
 	alert("11");
 	alert(msg);
 }

user.js
单击button反回为空，服务器错误是

2007-7-18 14:00:46 org.directwebremoting.util.CommonsLoggingOutput error

郁闷了一天实在是找不出原因~~~！
还望指点~！

web.xml的内容 ~~~~！

看看你的org.li.dwr.User的路径是否对了

没有问题，而且我在里面加了一个return "hello" ; 的返回值方法就可以了

已经想明白了~~~~~！
多谢大家的帮助。

你知道了，我们还不知道呀，应该把问题的原因写出来吗。

9494让我们也明白一下吧。

converter参数设置写反了.match=user路径, converter="bean"

8楼的正解，哈哈哈
