Issue
I am creating simple Login web app in jsp and servlet in IntelliJ IDEA Ultimate 2020.2.
The following is my index.jsp
<%@ page contentType="text/html;charset=UTF-8" language="java" %>
<html>
<head>
<title>Calculator</title>
</head>
<body>
<form method="post" action="/LoginServlet">
UerName:<input type="text" name="t1"><br>
Password:<input type="text" name="t2"><br>
<input type="submit" value="Ok"><br>
</form>
</body>
</html>
This is my servlet. It is located at src->main->java->francis
@WebServlet(name = "LoginServlet")
public class LoginServlet extends HttpServlet {
protected void doPost(HttpServletRequest request, HttpServletResponse response) throws ServletException, IOException {
PrintWriter out = response.getWriter();
out.println("Welcome.....");
}
}
Web.xml is
<?xml version="1.0" encoding="UTF-8"?>
<web-app xmlns="http://xmlns.jcp.org/xml/ns/javaee"
xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance"
xsi:schemaLocation="http://xmlns.jcp.org/xml/ns/javaee http://xmlns.jcp.org/xml/ns/javaee/web-app_4_0.xsd"
version="4.0">
<servlet>
<servlet-name>LoginServlet</servlet-name>
<servlet-class>francis.LoginServlet</servlet-class>
</servlet>
<servlet-mapping>
<servlet-name>LoginServlet</servlet-name>
<url-pattern>/LoginServlet</url-pattern>
</servlet-mapping>
</web-app>
But the Output screen is...
Please help me. Thanks in advance
Solution
Replace
<form method="post" action="/LoginServlet">
with
<form method="post" action="LoginServlet">
which will be automatically be translated into the-context-path/LoginServlet. Note that the path you put into action attribute is relative to the context path.
