Migrate ManagedConnectionFactory login module

[valsaraj007]

for (MBeanServer server : MBeanServerFactory.findMBeanServer(null)) {

                if (server.getDefaultDomain() != null && server.getDefaultDomain().equals(getServerId())) {

                    ObjectName managedConnectionFactoryObject = new ObjectName(getManagedConnectionFactoryName());

                    ManagedConnectionFactory mcf = (ManagedConnectionFactory) server.getAttribute(managedConnectionFactoryObject, getManagedConnectionFactoryKey());

                    PasswordCredential cred = new PasswordCredential(principalName, password);

                    subject.getPrivateCredentials().add(cred);

                    cred.setManagedConnectionFactory(mcf);

                }

            }

I have this code in custom login module working with JBoss-4,2,2.GA but in WildFly-8.2, it is not entering into the block. What is the solution to migrate this to WildFly?

Thanks!
