Tomcat can't set properties for DataSource connection

I'm trying to implement a form based authentication system using Tomcat 10. I've checked my form using a UserDatabaseRealm and it works fine. I've added my Realm in the META-INF/context.xml file and Resources as a Global Resource in the server.xml file. I've used a Resource-Link file for accessing the Resource defined in server.xml file.

When I run the app on the server I get the error saying the app couldn't set the SQL properties I've defined. When I enter the username I have entered in the form, I get a 403 error and the console log says it couldn't find the column 'user_name' in 'where clause'.

I have created a MySQL database called tomcat_mail. It has three tables :

  1. tomcat_users : user_name, password
  2. tomcat_roles : role_name
  3. tomcat_users_roles : user_name, role_name

I'll attach my server.xml, context.xml and web.xml files here.
