我在做一个简单的jsp页面，主要是：在包chapter35中创建一个新的类ComputeTax.java,然后在jsp中导入这个类。。。最后运行时出现了500的错误。。。求助各位大侠前辈啊
jsp的代码如下：
<%@ page import="ComputeTax"%>
<html>
<head>
<title>ComputeTax</title>
</head>
<body>
<%
String status=request.getParameter("status");
double income=Double.parseDouble(request.getParameter("income"));
double tax=computeTax(income);
out.println("Taxable Income: <b>"+income+"</b><br>");
out.println("Filing Status: <b>"+status+"</b><br>");
out.println("Tax: <b>"+tax+"</b><br>");
%>
</body>
</html>
我的java源代码的主要代码如下：
public class ComputeTax {
double computeTax(double income){
税的计算方法。。。
}
}找不到这个页面，你把你的那个类放在一个包里面再试试呢？
这个没有用啊。。。依旧显示的是：
HTTP Status 500 -
