I am making a simple Maven Project using Eclipse. There is a form that has Username and Password and a submit button.When I enter and submit the default username(admin) and password(admin). It should either show a page with "Pass" or "Fail" text if they match. But when I submit the form it shows [this error.] (https://i.stack.imgur.com/dw6Rt.png). I am using Tomcat version 10.1 with javax servlet version 4.0.1 for this project and Eclipse EE edition.
This is my file directory for the project.
I have installed the required dependency in the pom.xml file and got the servlet in the web.xml file as well. But I don't know why this issue is still there. I have tried other similar stack overflow solutions and from Google too but none of them worked so far.
