初学struts的小问题，JSP中的代码如何用struts 分离开。。。。 解决马上给分。
以下是我的JSP页面：
<body>
<%
if(application.getAttribute( "count ")==null){
application.setAttribute( "count ", "1 ");
out.println( "first user ");
out.print(application.getAttribute( "count "));
}
else{
int a=Integer.valueOf((String)application.getAttribute( "count "));
application.setAttribute( "count ",Integer.toString(a+1));
out.print(application.getAttribute( "count "));
}
%>
</body>
我想把这些代码用struts分离开，可是不知道这些代码往哪里写了，麻烦大哥帮我一下，最好有详细的代吗，有的人告诉我说写一个bean，可是这个bean怎么写呀？
