表单信息保存到session，跳转到servlet，一直报404错误
自学servlet中。做一个简单的表单提交，将信息保存到session中并查看，表单提交没有问题，但是跳转到/servlet/testSession 一直是404错误。。求大神帮忙解决！！！
包servlet下类Register：
package servlet;
import java.io.IOException;
import java.io.PrintWriter;
import javax.servlet.ServletException;
import javax.servlet.http.HttpServlet;
import javax.servlet.http.HttpServletRequest;
import javax.servlet.http.HttpServletResponse;
import javax.servlet.http.HttpSession;
public class Register extends HttpServlet {
public void doPost(HttpServletRequest request, HttpServletResponse response)
throws IOException, ServletException {
request.setCharacterEncoding("GBK");
String name = request.getParameter("name");
String pass = request.getParameter("pass");
String gender = request.getParameter("gender");
String[] hobby = request.getParameterValues("hobby");
String class1 = request.getParameter("class");
String introduce = request.getParameter("introduce");
String s_hobby = "";
if (hobby != null) {
for (int i = 0; i < hobby.length; i++) {
s_hobby = s_hobby + hobby[i];
if (i < hobby.length - 1) {
s_hobby = s_hobby + ",";
}
}
}
HttpSession session = request.getSession();
session.setAttribute("name", name);
response.setContentType("text/html;charset=GBK");
PrintWriter out = response.getWriter();
out.println("<html>");
out.println("<head>");
out.println("<title>处理表单</title>");
out.println("</head>");
out.println("<body>");
out.println("<h1 align=center>你好！</h1>");
out.println("<p>姓名：" + name);
out.println("<p>密码：" + pass);
out.println("<p>性别：" + gender);
out.println("<p>爱好：" + s_hobby);
out.println("<p>班级：" + class1);
out.println("<p>自我介绍：");
out.println("<p>" + introduce);
out.println("</body>");
out.println("</html>");
out.println("<p><a href='testSession'>测试session</a>");
}
}
包servlet下类TestSession：
package servlet;
import java.io.IOException;
import java.io.PrintWriter;
import javax.servlet.ServletException;
import javax.servlet.http.HttpServlet;
import javax.servlet.http.HttpServletRequest;
import javax.servlet.http.HttpServletResponse;
import javax.servlet.http.HttpSession;
public class TestSession extends HttpServlet {
protected void doGet(HttpServletRequest request, HttpServletResponse response)
throws ServletException, IOException {
HttpSession session = request.getSession();
String name = (String)session.getAttribute("name");
response.setContentType("text/html;charset=GBK");
PrintWriter out = response.getWriter();
out.println("<html>");
out.println("<head>");
out.println("<title>你好</title>");
out.println("</head>");
out.println("<body>");
out.println("<h1 align=center>你好！" + name + "</h1>");
out.println("</body>");
out.println("</html>");
}
}

------解决方案--------------------
protected void doGet(HttpServletRequest request, HttpServletResponse response)
改成公共方法
public void doGet(HttpServletRequest request, HttpServletResponse response)
