Hmmm. I didn't know that, I guess. Well, I wonder if that long string requires some kind of escape character to be inserted in it?

My understanding is that the "simple" dburl cannot be used for RAC databases. Also, I tried removing/adding the validationQuery from the context.xml, however that did not work either :(. When I researched the ORA-00911 error, it typically is thrown when you haven an invalid character in the query. However I get this error when trying to get a connection via the JNDI reference to the pool. The strange thing is that this works via a simple java program that directly uses the JDBC/Oracle driver. I can work around the issue by not using JNDI in the web app, however I am not then able to use pooling I guess.

At your line with the DBURL, I have something much more concise. Where you have public static final String DBURL = "jdbc:oracle:thin:@(DESCRIPTION = (ADDRESS = (PROTOCOL = TCP)(HOST = abc-def-scan.corp.xyz.com)(PORT = 1521)) (CONNECT_DATA = (SERVER = DEDICATED) (SERVICE_NAME = SAMPLE.WORLD) ) )"; I simply have: String dbURL = "jdbc:oracle:thin:@dbservername.1526:servicename"; I set the rest of that string in my tnsnames.ora file - not sure if you're unable to do this or not. I'd think you'd do it there. Could that be where the error is stemming from? The rest of it looks correct to me. -----Original Message----- From: tsidhu [mailto:[hidden email]] Sent: Thursday, January 10, 2013 9:52 AM To: [hidden email] Subject: JNDI setup oracle 11 g Hello, I am able to connect to my database from a stand alone java program, however the same connection information throws an exception when used via JNDI.
