jsp动作<jsp:setproperty>标签中如何取到表单数据的复选框的值？

--------------------------------javabean----------------------------------------
private String name = "";
private String password = "";
private String confirmPassword = "";
private String sex = "";
private String[] hobbys = null;

set() and get()方法省略。。

--------------------------------index.jsp----------------------------------------
表单注册。

------------------------show.jsp页面----------------------------------
<%request.setCharacterEncoding("UTF-8");%>

<jsp:useBean id="user" class="myEL1.User" scope="page"></jsp:useBean>

<jsp:setProperty name="user" property="*"/>

<jsp:setProperty property="hobbys" name="user" value="<%=request.getParameterValues("hobbys") %>"/>

    用户名：${user.name}<br>
    密码：${user.password}<br>
    确认密码：${user.confirmPassword}<br>
    性别：${user.sex}<br>
    爱好：${user.hobbys[0]}${user.hobbys[1]}${user.hobbys[2]}${user.hobbys[3]}

-------报错提示：/show.jsp (line: 5, column: 58) Attribute value request.getParameterValues("hobbys")  is quoted with " which must be escaped when used within the value--------------

用了jsp:setProperty设值，可以用jsp:getProperty取值啊。比如
如果是复选框的话，在后台获取爱好时做一下处理，然后传到页面
