这是我的index.jsp
代码:
<html>
<head>
<meta http-equiv="Content-Type" content="text/html; charset=ISO-8859-1">
<title>Index JSP File</title>
</head>
<body>
<form action="/IndexController" method="get">
<table>
<tr><td>Enter Your Name :</td> <td><input type="text" name="name"/></td></tr>
<tr><td><input type="submit" value="Submit" /></td></tr>
</table>
</form>
</body>
</html>
这是我的IndexController
Servlet 代码:
public class IndexController extends HttpServlet {
protected void doProcess(HttpServletRequest request, HttpServletResponse response) throws ServletException, IOException {
String uname = request.getParameter("name");
response.sendRedirect("welcome.jsp?name="+uname);
}
protected void doGet(HttpServletRequest request, HttpServletResponse response) throws ServletException, IOException {
doProcess(request, response);
}
protected void doPost(HttpServletRequest request, HttpServletResponse response) throws ServletException, IOException {
doProcess(request, response);
}
}
这是我的welcome.jsp
页面代码
<html>
<head>
<meta http-equiv="Content-Type" content="text/html; charset=ISO-8859-1">
<title>Insert title here</title>
</head>
<body>
<% String fname = request.getParameter("uname");%>
<h1>Welcome to JSP World, <%=fname%></h1>
</body>
</html>
当我通过 Java EE 运行时运行它时,我得到了一个index.jsp
页面,但是在输入名称并单击提交后,我得到了以下错误:
Error 404 - Not Found No context on this server matched or handled this request. Contexts known to this server are: JSPExample(/JSPExample)
