Solution

I redownloaded pathed drivers ojdbc6.jar from OTN.

To check, whether you have pathed driver or not, follow these steps

> java -jar ojdbc6.jar

The unpatched jar prints

Oracle 11.1.0.6.0-Production JDBC 4.0 complied with JDK6

and the patched jar prints

Oracle 11.1.0.6.0-Production+ JDBC 4.0 complied with JDK6

If you use ojdbc5 it will say 3.0 and 1.5.
