Hi all,

I have previously been able to connect to my 9i database using SQLDeveloper from my desktop to the server and today am not able to connect to the database

I am the network and system administrator (Windows) and know there have been no changes made to *anything* in the network.

I have confirmed that the listener is up and running via both telnet and tnsping.

I can connect to the database using sql*plus in a command window.

I have downloaded the latest version of SQLDeveloper thinking that this may have been the problem but I still cannot connect.

As I said, I can connect using SQL*Plus but it is frustrating me to use that...

my car can not go.
tell me how to make my car go.

my truck goes OK but burns too much gas.
You have a mystery & we have NO clues.

and the error message is ...
