求教有关DWR实现调用有JavaBean参数的java方法

[Sunksubmarine]

dwr.xml如下：
<!DOCTYPE dwr PUBLIC
"-//GetAhead Limited//DTD Direct Web Remoting 2.0//EN"
"http://getahead.org/dwr/dwr20.dtd">

<dwr>
<allow>
<create creator="new" javascript="Blbean">
<param name="class" value="bean.Blbean"/>
<include method="isUse"/>
<include method="getUser"/>
</create>
<convert converter="bean" match="bean.User">
<param name="include" value="username,password" />
</convert>
</allow>
</dwr>


JSP如下：
<script src='dwr/interface/Blbean.js'></script>
<script src='dwr/engine.js'></script>
<script src='dwr/util.js'></script>
......
function callExfun(){
var user;
user={username:"lingx",password:"123456"}
Blbean.printUser(user);
}

bean.Blbean 的printUser方法如下：
......
public void printUser(User user){
System.out.println(user.getUsername());
System.out.println(user.getUsername());
}

bean.User如下：
......
private String username;
private String password;
public User(String s1,String s2){
this.username = s1;
this.password = s2;
}
public String get......
public void set.....
......


JSP加载时控制台信息如下：（没有错误或者警告）

就是没有办法实现调用printUser方法，本人新学dwr望高人指正~

提示的信息没有问题哦
你给User类加一个空构造方法试试。

[okey8]

function callExfun(){
var user;
user={username:"lingx",password:"123456"}
Blbean.printUser(user);
}

在dwr.xml 里面 找不到你所调用的 方法。。在 xml 里面也要定义
