struts.xml的配置问题，请高手指教
我在学习struts2，练习其中的重定向的一个的小例子，其中有action1.jsp负责表单的内容，提交到Action1的action类，有一个待转发到的Action2类，有一个处理结果的actin2.jsp，action1.jsp的代码如下：
<body>
<form action="action1.action">
username:<input type="text" name="username" /><br/>
password:<input type="password" name="password" /><br/>
<input type="submit" value="submit"/>
</form>
</body>
Action1的代码如下：
public class Action1 extends ActionSupport
{
private String username;
private String password;
private String usernameAndpassword;
public String getUsername() {
return username;
}
public void setUsername(String username) {
this.username = username;
}
public String getPassword() {
return password;
}
public void setPassword(String password) {
this.password = password;
}
public String getUsernameAndpassword() {
return usernameAndpassword;
}
public void setUsernameAndpassword(String usernameAndpassword) {
this.usernameAndpassword = usernameAndpassword;
}
@Override
public String execute() throws Exception {
this.usernameAndpassword = this.username+ this.password;
return SUCCESS;
}
}
Action2的代码如下：
public class Action2 extends ActionSupport
{
private String username;
private String password;
private String usernameAndpassword;
public String execute()throws Exception
{
return SUCCESS;
}
public String getUsername() {
return username;
}
public void setUsername(String username) {
this.username = username;
}
public String getPassword() {
return password;
}
public void setPassword(String password) {
this.password = password;
}
public String getUsernameAndpassword() {
return usernameAndpassword;
}
public void setUsernameAndpassword(String usernameAndpassword) {
this.usernameAndpassword = usernameAndpassword;
}
}
action2.jsp的代码如下：
<body>
username:<s:property value="username"/><br/>
password:<s:property value="password"/><br/>
usernameAndpassword:<s:property value="usernameAndpassword"/><br/>
</body>
问题是我在struts.xml中的配置是这样的
<action name="action1" class="com.shengsiyuan.struts2.Action1">
<result name="success" type="redirectAction">
<param name="actionName">action2</param>
<param name="username">${username}</param>
<param name="password">${password}</param>
<param name="usernameAndpassword" >${usernameAndpassword}</param>
</result>
</action>
但是struts.xml中总是报错，错误提示是undefined actionnamespace parameter,请高手指教，我那里错了
[解决办法]
<result name="success" type="redirectAction">
action2?username=${username}&&password=${password}
</result>
[解决办法]
加上个<param name="namespace">/</param>
------解决方案--------------------
<param name="namespace">/</param>直接写这个就行了，不过我使用过，我们加过这个代码？如果传参数，我使用的session
[解决办法]
