一个最简单的JSP usebean的例子，调试有错误，大家帮忙看看啊！

有一个文件，java的编译成class。调试总是报错，麻烦各位看看。
usebean.htm
<form method="post" action="usebean.jsp">
<input type="text" name="name">

<select name="sex">
<option value="先生">先生</option>
<option value="小姐">小姐</option>
</select>

<input type="submit" name="submit" value="提交">
</form>

usebean.jsp
<%@page language="java" import="HelloBean;" %>

<jsp:useBean id="Hello" class="HelloBean" scope="request" >
<jsp:setProperty name="Hello" property="*" />
</jsp:useBean>

<html>
< %=Hello.getName()% >

< %=Hello.getSex()% >
</html>

HelloBean.java

public class HelloBean{
private String name="";
private String sex="";
public HelloBean(){
}
public void setName(String name){
this.name = name;
}
public String getName(){
return this.name;
}
public void setSex(String sex){
this.sex = sex;
