This is strange , the Jboss code which is failing here is | private LocalManagedConnection getLocalManagedConnection(Properties props,Properties copy) | throws JBossResourceException | { | try | { | String url = getConnectionURL(); | Driver d = getDriver(url); | Connection con = d.connect(url, copy); | if (con == null) | throw new JBossResourceException("Wrong driver class for this connection URL"); | | return new LocalManagedConnection(this, con, props, transactionIsolation, preparedStatementCacheSize); | } | catch (Exception e) | { | throw new JBossResourceException("Could not create connection", e); | } | } | This is from http://anonsvn.jboss.org/repos/jbossas/trunk/connector/src/main/org/jboss... d.connect(url, copy); seems to be failing . Can you use the Driver.connect(...) to get the connection in your stand alone application and see if it works ? Also make sure that you are using the same Oracle driver for running the stand alone application which is present in the Jboss server .
