求助：ActionContext.getContext().put("user",getUsername())前台JSP获取不到值
这是loginAction代码：public class LoginAction extends ActionSupport{
private String username;
private String password;
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 check(){
if(getUsername().equals("scott")&&getPassword().equals("tiger")){
System.err.println(username);
ActionContext.getContext().put("user",username);
return SUCCESS;
}
else{
return LOGIN;
}
}
}

这是JSP页面代码：
<html>
<head>
<meta http-equiv="Content-Type" content="text/html; charset=ISO-8859-1">
<title>welcome</title>
</head>
<body>
welcome,${sessionScope.user}!
<form action="showBooks.action" method="post">
<input type="submit" value="show books">
</form>
</body>
</html>
//===========================================================================

我去啊！！！！！太粗心了ActionContext.getContext().put("user",username);这句少了一部分，正确的是ActionContext.getContext().getSession().put("user",username);
细心！一定要细心！
补充：Java , Web 开发
