无法访问Servlet页面
Mun*_* A. 5 java jsp tomcat servlets
美好的一天,
我刚刚配置了tomcat并使用了java servlet页面.我是新手,无法成功点击索引页面,但如果我直接尝试点击表格动作并传递定义的参数,那么我就能看到结果.如果我遗失了什么,请指导我.
JSP - 代码
<div align="center" style="margin-top: 50px;">
<form action="CrunchifyServlet">
Please enter your Username: <input type="text" name="username" size="20px"> <br>
Please enter your Password: <input type="text" name="password" size="20px"> <br><br>
Please enter your Age: <input type="text" name="age" size="20px"> <br><br>
<input type="submit" value="submit">
</form>
</div>
Java - 代码
public class HelloCrunchify extends HttpServlet {
protected void doGet(HttpServletRequest request, HttpServletResponse response) throws ServletException, IOException {
// reading the user input
String username = request.getParameter("username");
String password = request.getParameter("password");
String age = request.getParameter("age");
PrintWriter out = response.getWriter();
out.println (
"<!DOCTYPE html PUBLIC \"-//W3C//DTD HTML 4.01 Transitional//EN\" +" +
"http://www.w3.org/TR/html4/loose.dtd\">\n" +
"<html> \n" +
"<head> \n" +
"<meta http-equiv=\"Content-Type\" content=\"text/html; " +
"charset=ISO-8859-1\"> \n" +
"<title> Crunchify.com JSP Servlet Example </title> \n" +
"</head> \n" +
"<body> <div align='center'> \n" +
"<style= \"font-size=\"12px\" color='black'\"" + "\">" +
"Username: " + username + " <br> " +
"Password: " + password + " <br> " +
"Age: " + age +
"</font></body> \n" +
"</html>"
);
}
}
web.xml中
<display-name>CrunchifyJSPServletExample</display-name>
<welcome-file-list>
<welcome-file>index.html</welcome-file>
<welcome-file>index.htm</welcome-file>
<welcome-file>index.jsp</welcome-file>
<welcome-file>default.html</welcome-file>
<welcome-file>default.htm</welcome-file>
<welcome-file>default.jsp</welcome-file>
</welcome-file-list>
<servlet>
<servlet-name>Hello</servlet-name>
<servlet-class>com.crunchify.jsp.servlet.HelloCrunchify</servlet-class>
</servlet>
<servlet-mapping>
<servlet-name>Hello</servlet-name>
<url-pattern>/CrunchifyServlet</url-pattern>
</servlet-mapping>
</web-app>
如果我试图点击这个localhost:9080/CrunchifyJSPServletExample/Crunchify.jsp我得到HTTP状态404.
帮助将不胜感激.
谢谢
