    Creating principal from custom headers

    Cassio Nishiguchi Newbie

      Hi,
      I'm trying to create a Principal based on information retrieved from custom headers that are fed into JBoss by an Apache and mod_jk connector instance. This principal has to be available for the application via the normal calls, as if the user had been authenticated by the usual FORM authentication.
      I wrote a valve that creates a GenericPrincipal and puts it in the request with request.setUserPrincipal(). However, that causes a NPE when Jboss tries to look up the user's roles:
      ERROR [org.apache.catalina.connector.CoyoteAdapter] An exception or error occurred in the container during the request processing
      java.lang.NullPointerException

      How can I fix this, or is there a better way to accomplish what I'm trying to do?
