JSP tomcat 不能编译，请高手指点。
本人初学 jsp，写了个简单的jsp页面，但是tomcat报错，
代码如下：
<%@ page contenttype= "html/text ";charset= "gb2312 " %>
<html>
<head>
求平方根
</head>
<body>
<p> 请输入一个正数，点击按钮求平方根：
<center>
<form action= " " method =post name =form>
<input type = "text " name = "ok ">
<br> <input type = "submit " value= "送出 " name= "submit ">
</form>
<% String str=requst.getparameter( "ok ");
if(str==null){
str = "1 ";
}
try{
double number = Integer.parseInt(str);
out.println(Math.Sqrt(number));
}
catch(Exception e){
out.println( "请出入数字 ");
}
%>
</center>
</body>
</html>

------解决方案--------------------
根据错误来看你的这一句 <%@ page contenttype= "html/text ";charset= "gb2312 " %> 有问题
删掉它或者改为
<%@ page contentType= "html/text;charset=gb2312 " %>
