[em1]我刚学jsp不太好，要求做有循环有判断的作业，我本想做输入年月日告诉你是这年的第几天，可是老师给的例子就有这个，例子是用if编的，我就想改个switch的，可是运行不队，我给你的附件有我自己的程序你看看，是输入月日告诉你是什么星座的，还有一个是别人告诉我的判断闰年的，各位帮我看看怎么改，星座的还可以做成什么大同小异的，我觉得意义不好，拜托了!
一运行，点提交，就不是到应该的jsp页，而是像出错了，到了有文件名字的白页．
要是运行给的例子就可以顺利运行程序．
那是不是还是程序的问题，不是环境设置的问题

以下是jsp的代码
<%
string month =request.getParameter("month");
string data =request.getParameter("data");
int m=Integer.parseInt(month);
int n=Integer.parseInt(data);
out.print(m);
out.print(n);
switch(m)
case 1: switch(n)
{case n<=21: out.print("shuiping");break;
case n>=22: out.print("tianxie");break;}break;
case 2: switch(n)
{case n<=21: out.print("tianxie");break;
case n>=22: out.print("muyang");break;}break;
case 3: switch(n)
{case n<=20: out.print("my");break;
case n>=21: out.print("by");break;}break;
case 4:switch(n)
{case n<=21: out.print("tianxie");break;
case n>=22: out.print("muyang");break;}break;
