I am using form based authentication (tomcat 7.0.34) and I have the implementation of custom realm class which extends RealmBase class. Inside the getPrincipal() method implementation, I am calling backend service to save some login details. I need to pass host name to backend (I have 2 applications running under different hosts connected to same DB, so to know the login source of user). Hosts are configured in server.xml.
Any help/links/URL much appreciated. Neeraj
