大牛们，帮我看看这段动态网页小程序哪里出错了？

 想实现点赞功能
main.jsp:
<html>
<body>
<%!int number;%>
<jsp:useBean id="simple" scope="application" class="shiyaner.Simple"/>
<a href="#" onclick="js_method();return false;">点赞+1</a>
                    |
                    点赞<%=simple.getCount()%>次
                    <script>
                    function js_method(){
                    <%number=simple.getCount();%>
                    <%simple.setCount(number++);%>
                    }
                    </script>
  </body>
</html>


Simple.java:
package shiyaner;
public class Simple {
    private int count;
    public int getCount() {
        return count;
    }
    public void setCount(int count) {
        this.count = count;
    }
}

    simple.setCount(++number);
    或者
    simple.setCount(number+1);
