Uh... don't do that. Either undeploy the manager app or use a different <Realm> that doesn't use that type of User object. Or, write your own factory that returns serializable objects. > What can I do to make the MemoryUser serializable and why is it trying > to sync it with other nodes? It's probably trying to sync the session with other nodes, and this object is stored in the session. The rest of the stack trace would probably indicate that the cluster is trying to replicate sessions (or just this object, as it is being inserted into the session) or something like that. - -chris -----BEGIN PGP SIGNATURE----- Version: GnuPG v1.4.9 (MingW32) Comment: Using GnuPG with Mozilla - http://enigmail.mozdev.org/ iEUEARECAAYFAkpOGjoACgkQ9CaO5/Lv0PAKfgCVGPJmrP+xs5Aypo60NEU8uk2y TwCfTuaeseQX6b4g3qJNFCU85oezZGU= =iNCj -----END PGP SIGNATURE----- --------------------------------------------------------------------- To unsubscribe, e-mail: users-unsubscr...@tomcat.apache.org For additional commands, e-mail: users-h...@tomcat.apache.org
