However, when I run my servlet, they did not give me the successful login message nor redirect me to the next page. My database is using Msaccess and the field for the variable is userid and password. 4.0.0 servletLogin 0.0.1-SNAPSHOT jar servletLogin UTF-8 8 8 9.4.18.v20190429 1.5.2 1.0.0 1.2 've tried using a PreparedStatement to verify login userid and password. In section, add the following two properties:

I’m going to step you through all of the project code and explain everything, but if you want to cheat and just view the final application, you can find it here:įirst add the appropriate dependencies to the pom.xml file. Now we are ready to actually add authentication into the app. Protect Your Application Using Servlet Login NOTE: You can import multiple users from CSV files by selecting the More Actions menu button in the Directory > People section of the Okta Admin Console. Java web implementation simple login page (MyBatis+jsp+servlet+html+css+javascript) with source code, Programmer Sought, the best programmer technical posts. I figure if my secret recipes somehow become public, he can always go back to 1955 and tell my grandmother not to trust me with them! I’ve chosen to create Marty McFly as a user.

The code that powers this app can be found on my GitHub.īecause we’ll be modifying this application, you’ll want to clone or download this starter code. To get started, we’ll use a simple application I wrote that shares secret family recipes. Specify the JSP Pages for Login and Profile.Create the AuthenticationServletContextListener Class.Create a AuthenticationLambdaServlet Class.Create an OktaFilter Class to Confirm Authentication.Protect Your Application Using Servlet Login.Create User Accounts in the Okta Admin Console.However, you can use any IDE or editor you please. NOTE: Throughout this post, I’ll use Eclipse, as it is my preferred IDE. This is a simple client library for interacting with the Okta Authentication API. To use the Okta API, you’ll make use of the Okta Java Authentication SDK. Using Okta gives you a simple, secure user store for your application. A true old school approach would be to build an identity service all yourself, but that would transform this already long blog post into a massive novel. The sample app you’ll build will make use of the Okta Authentication API for user authentication.
However, this post is for those who want nothing handed to them! Well, except for some sample code. There are more modern, technologically savvy ways to handle authentication within your application, namely OAuth 2.0 and OIDC, which I will touch upon later. That’s why today, you’ll build an application from the ground up using Java Servlets with a login form. This approach helps you understand core development principles and the inner workings of everyday abstractions. It can be very satisfying to build an application “the hard way”, using few conveniences.
