我想顯示一個網頁[索引頁面],有3個選擇汽車的選項。汽車可以通過單選按鈕或TextBox進行選擇。HTML單選按鈕和Servlet
當選擇一個特定的汽車時,servlet應該響應顯示用戶選擇的客戶端。另外,servlet應該計算所選汽車的價格。但現在,我沒有進入價格,只是顯示用戶的選擇回到他的瀏覽器。
我收到錯誤類型的現狀報告 消息/carShop/tish.com.CarServlet2 描述所請求的資源(/carShop/tish.com.CarServlet2)不可用。 什麼是錯的: -

的Servlet: -

import javax.servlet.ServletException;
import javax.servlet.http.HttpServlet;
import javax.servlet.http.HttpServletRequest;
import javax.servlet.http.HttpServletResponse;
public class CarServlet2 extends HttpServlet {

protected void doPost(HttpServletRequest req, HttpServletResponse resp) throws ServletException, IOException {
System.out.println("Testing my Car Sevlet");
//System.out.println(arg0.getInitParameter("Year"));
//config =arg0;
String [] car = req.getParameterValues("car");
PrintWriter writer = resp.getWriter();
resp.setContentType("text/html");
writer.print("<html> <body>");
writer.print("<hl> Your choice is </hl>");
for (String s: car)
{
writer.print("<l1>" + s+ "/l1>");
}
writer.print("</body></html> ");
}
}
