Try the following

I had encountered the same issue. We were using spring and it has a class called NativeJdbcExtractor. It has many implementations and the following one works for TomCat. There is a specific implementation for Jboss called the JBossNativeJdbcExtractor

In your DAO you can inject the bean and use the following method

protected NativeJdbcExtractor jdbcExtractor;
Connection conn=jdbcExtractor.getNativeConnection(oracleConnection);
