我正在使用do post方法作为我的method.I试图在Tomcat 6.0.37上部署servlet。 Tomcat也是。我已经把项目放在webapps文件夹中。当我打开本地主机URL时，我得到了Tomcat的主页。当我填写了欢迎JSP形式和点击提交按钮，我得到以下错误：试图在Tomcat服务器上运行web应用程序，但无法运行
The requested resource (/Airlines/ChooseAirline.do) is not available.
我搜查，但找不到任何东西，可以帮助我。我试图简单地在点击JSP上的提交按钮后收到一条消息，并检查它是否涉及Servlet。
我的web.xml如下 -
<?xml version="1.0" encoding="UTF-8"?>
<web-app xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance" xmlns="http://java.sun.com/xml/ns/javaee" xmlns:web="http://java.sun.com/xml/ns/javaee/web-app_2_5.xsd" xsi:schemaLocation="http://java.sun.com/xml/ns/javaee http://java.sun.com/xml/ns/javaee/web-app_2_5.xsd" id="WebApp_ID" version="2.5">
<display-name>Airlines</display-name>
<welcome-file-list>
<welcome-file>ChooseAirline.jsp</welcome-file>
</welcome-file-list>
<servlet>
<servlet-name>ChooseAirline</servlet-name>
<servlet-class>com.chooseairline.ChooseAirlines</servlet-class>
</servlet>
<servlet-mapping>
<servlet-name>ChooseAirline</servlet-name>
<url-pattern>/ChooseAirline.do</url-pattern>
</servlet-mapping>
</web-app>
在我的servlet我只是在尝试打印你好世界网页上的输出。我的servlet代码如下 -
package com.chooseairline;
import java.io.IOException;
import java.io.PrintWriter;
import javax.servlet.*;
import javax.servlet.http.*;
public class ChooseAirlines extends HttpServlet{
public void doPost(HttpServletRequest request,HttpServletResponse response) throws ServletException
{
String requestDropDown = request.getParameter("dropDownSelectClass");
System.out.println("the value here is "+requestDropDown);
response.setContentType("text/html");
PrintWriter out;
try {
out = response.getWriter();
out.println("<html>");
out.println("<head>");
out.println("<title>Hello World!</title>");
out.println("</head>");
out.println("<body>");
out.println("<h1>Hello World!</h1>");
out.println("</body>");
out.println("</html>");
} catch (IOException e) {
// TODO Auto-generated catch block
e.printStackTrace();
}
}
}
我是Servlet开发和Apache服务器的新手。我尝试了很多次，但得到同样的问题。
我还包括我的JSP和这个。请检查它 -
