Redirect users to index.jsp if they have no access to it.

You need an application server like Tomcat. You can use an in-memory realm to hold your users.Then you need to configure the relevant resources in your web.xml file. And finally you need to write the login.jsp and the index.jsp files. For a step by step guide have a look here.

Thanks. Is it possible to do something like below using javascript.

<script>
    var isAdmin = conf.isAdmin();
    if ((isAdmin === null) || !isAdmin) {
                result.put("reason", "Permission Denied");
                throw new UserServletException();
            }
    </script>

Select allOpen in new window

I have a configuration.java file basically returns a boolean value if the user logs in is an admin or not. I am trying to take this value an throw an error for regular users if they are not admins. Here is the function return to check if the user is an admin or not

public boolean isAdmin() {
        boolean hasRole = false;

        try {
            
            Subject sbj  = SecurityUtils.getSubject();
            String adminRole = Props.getProperty(ROLE_KEY);
            hasRole = sbj.hasRole(adminRole);
            
        } catch (Throwable t) {
            log.error(t.getMessage(), t);
        }

        return hasRole;
    }
