我接受来自html页面的名字并在“firstservlet”类中显示它。在第一个servlet类中，我试图通过创建html文本框并重定向到“secondservlet”类来接受姓氏，我可以在其中显示名字和姓氏。但我得到404错误。如何解决此错误。
FirstServlet.java
protected void doGet(HttpServletRequest request, HttpServletResponse response) throws ServletException, IOException {
response.setContentType("text/html");
PrintWriter out=response.getWriter();
HttpSession session=request.getSession();
out.println(session.isNew());
String name=request.getParameter("FirstName");
request.setAttribute("name", name);
out.println("First name is " +name);
out.print("\n");
out.println("<html>");
out.println("<body>");
out.println("<form action=SecondServlet/>");
out.println("Enter LastName<input type=text name=LastName>");
out.println("<br>");
out.println("<input type=submit />");
out.println("</form>");
out.println("</body>");
out.println("</html>");
String lname=request.getParameter("LastName");
request.setAttribute("lname", lname);
RequestDispatcher rd=request.getRequestDispatcher("SecondServlet");
rd.forward(request, response);
}
SecondServlet.java
protected void doGet(HttpServletRequest request, HttpServletResponse response) throws ServletException, IOException {
response.setContentType("text/html");
PrintWriter out=response.getWriter();
String name=request.getParameter("FirstName");
request.setAttribute("name", name);
out.println("First name is " +name);
out.println("<br>");
String lname=request.getParameter("LastName");
request.setAttribute("name", lname);
out.println("Last name is " +lname);
out.println("<br>");
}
