Hi I found here a simple oracle testing method: http://bderzhavets.blogspot.com/2007/06/deployment-seam-application-again... 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?
