In reply to Ravi Bandakkanavar. Thanks, my problem is solved! Actually I was using Tomcat 10, so I had to use Jakarta servlet instead of javax servlet.

Hi Ayush,

Please check on 2 things.

1. Whether you have uploaded multiple servlet Jar files.
2. whether the classes and classpath given in web.xml are correct.

I am getting an error:

SEVERE: Allocate exception for servlet [LoginServlet]
java.lang.ClassCastException: class com.login.controller.LoginServlet cannot be cast to class jakarta.servlet.Servlet (com.login.controller.LoginServlet is in unnamed module of loader org.apache.catalina.loader.ParallelWebappClassLoader @63787180; jakarta.servlet.Servlet is in unnamed module of loader java.net.URLClassLoader @70177ecd)

As soon as I enter login credentials, I get the above error that LoginServlet is not a servlet, even though I have extended LoginServlet with HttpServlet.

Please suggest a solution.

In reply to Damian O’keefe.

Hi Damian,

I believe scriptcase is PHP based development platform. Depending on the language you are comfortable with, choose one.

The above application is in Java. It explains how a role-based application is built. It’s a basic one. You can add additional features as per the requirement for each role.
