I have a NetBeans web project on Tomcat 8.0.15, MySql (with Jconnector), Servlet/Jsp. I need a secure login!!!
There is a login page. On successful login, if it is admin, servlet redirects to the admin page, if username is of a standardUser, the servlet redirects to the main page.
For now nothing works. The page is not redirected by servlet, on submit button press the error.html appears and shows response.getStatus() is 0!!! I tested(without login) servlet for username/password check against the DB and it works.
so Here is my code files: login.jsp:
<form id="loginForm" method="POST" action="j_security_check">
<input name="j_username" id="j_username" type="email" value="test.admin@test.com"></input>
<input name="j_password" id="j_password" type="password" value="test"></input>
<input id="loginSubmit" type="submit" value="Login"></input></form>
web.xml:
<servlet>
<servlet-name>LoginServlet</servlet-name>
<servlet-class>ProjectP.Auth</servlet-class>
</servlet>
<servlet-mapping>
<servlet-name>LoginServlet</servlet-name>
<url-pattern>/j_servlet_check</url-pattern>
</servlet-mapping>

Context.xml:
<Context antiJARLocking="true" path="/ProjectP" allowCasualMultipartParsing="true" >

userRoleTable="userroles" roleNameCol="role"
auth="Container" maxTotal="100" maxIdle="30" maxWaitMillis="10000"/>
</Context>
LoginServlet.java:
@WebServlet("/j_servlet_check/*")
@MultipartConfig
public class LoginServlet extends HttpServlet {
protected void doPost(HttpS .......
response.setContentType("text/html;charset=UTF-8");
String username, password;
try {
username = request.getParameter("j_username");
password = request.getParameter("j_password");
if (checkLoginUser(username, password)) {
response.sendRedirect("./index.html");
HttpSession session=request.getSession();
session.setAttribute( "username", username );
request.getRequestDispatcher("../admin/Administration.jsp").forward(request, response);
Is context.xml - realm needed?
So, how to create a secure login?
