When i want to "add attributes" in my monitor (a websphere server 5.1 with security mode) i have always this message
com.ibm.websphere.management.exception.ConnectorException: ADMC0016E: Impossible de cr�er le connecteur SOAP pour se connecter � l'h�te pc9124 sur le port 8880
When i disable security in my server, all works fine !!!
