The OC4J server embedded in JDeveloper 10g or 11g does not support JDBC 4.0 specification; but in a later version of JDeveloper that supports JDBC 4.0, the JDBC 4.0 features may be added to the JSF application used to create a Data Table.

To use the JDBC 4.0 features you would need to download the Oracle database 11g JDBC 4.0 drivers JAR file, ojdbc6.jar from http://www.oracle.com/technology/software/tech/java/sqlj_jdbc/htdocs/jdbc_111060.html. Copy ojdbc6.jar to the j2ee/home/lib directory, which is in the runtime class path of web applications running in OC4J server. As JDBC 4.0 drivers require JDK 6.0, we would also need to set J2SE version to JDK 6.0. To set the JDK version select Tools | Project Properties and select Libraries...
