[jboss-user] [Installation, Configuration & DEPLOYMENT] - jboss can't connect to Oracle

[iscsi]

Hi

I found here a simple oracle testing method: 
http://bderzhavets.blogspot.com/2007/06/deployment-seam-application-against.html
i tried it but i have a problem with a connection, so i got this error/warn:

12:31:49,721 WARN  [JBossManagedConnectionPool] Throwable while attempting to get a new connection: null
org.jboss.resource.JBossResourceException: Could not create connection; 
- nested throwable: (java.sql.SQLException: Io exception:
 The Network Adapter could not establish the connection)

i found here an answer for this : 
"This stack trace is probably due to using an old oracle 
JDBC driver with a newer oracle engine"

So i found two driver, where the server run ojdbc5.jar, ojdbc6.jar
, and i download ojdbc14.jar but i got the same error message.

So have you got any idea what would be the problem?
Or where should i looking for the bug, or which log files should i check?

THanks,

Istvan
