Login Authentication using JSP, Servlet, MySQL in JAVA

In this example we will show you how to authenticate and login user against database username and password. This program consists of a JSP page and a Servlet to authenticate the user against database username and password.
User enters the username and password on the JSP page and clicks on the "Sign-In" button. On the form submit event, data is posted to the servlet for authenticating the user. Servlet makes JDBC connection and authenticate the user. Before submitting data to servlet, javascript is ensuring that none of the fields must be empty.
We are using tomcat server for running Servlet and JSP page. You can use any browser to test the application. We are using two files AuthenticLogin.jsp and LoginAuthentication.java and we are making the application in "webapps/JSPMultipleForms" in tomcat server.
