public static void setValue( Object tree, Map context, Object root, Object value )     throws OgnlException
    {
        OgnlContext ognlContext = (OgnlContext)addDefaultContext(root, context);
        Node n = (Node) tree;

        n.setValue( ognlContext, root, value );
    }

// n 既是 JSP页面 form 表单中的 input 元素  的name 属性

比如 <input name="user.username" value="123"/>  

然后在 ognl 中 通过action 中的 setter 方法

将调用 ognl.Ognl.java 中的 上述方法：

n ==>   user.username

value ==> 123
