isqlplus is not reachable

Hi there,

Some days ago the isqlplus service was reachable but now it seems something has changed - the site just doesn't show up...

Where could I start to search for problem?

Some useful info:
Oracle 10g, on Fedora Core 2
I don't remember having changed the firewall settings - so I guess it's not a firewall matter. The service isn't even reachable through localhost. Enterprise Manager console (port 5500) is working, so the OC4J server seems to be ok.
I try to start isqlplus with: "isqlplusctl start" output is:
iSQL*Plus 10.1.0.2.0
Copyright (c) 2004 Oracle. All rights reserved. Starting iSQL*Plus ...
iSQL*Plus started.

But when I try to stop it (isqlplusctl stop), it says: iSQL*Plus 10.1.0.2.0
Copyright (c) 2004 Oracle. All rights reserved.

Stopping iSQL*Plus ...
Error: Unable to find java:comp/ServerAdministrator: Lookup error: java.net.ConnectException: Connection refused; nested exception is:

        java.net.ConnectException: Connection refused

I deleted the database once (not the whole server), and created a new one with a different name - could this be the reason? I re-ran emca, and changed the listener configuration.
But again: the webbased Enterprise Manager is working....

Thanks in advance for any clues.

kind regards,
