Unable to log onto the Oracle MapViewer 11gR1 console

Hi,

I have a Glassfish server 3.1.2.2 running on Linux.
I can connect to the Glassfish console with the default admin/password.

I have deployed Oracle MapViewer 11gR1 on it.

I can access the URL of the MapViewer Server console as:
http://:8080/mapviewer

But I am unable to log onto the MapViewer Server console with the default admin/password of the Glassfish console.

Does someone know how to sole this problem>

Thanks by advance for any indication/tip.

Kind Regards.
