When adding third party libraries to your application, you must be sure they are in the Build Path of your application. In case of web applications, every third party library must be inside the WEB-INF/lib of the application so when deployed to the server (Tomcat, JBoss, etc.) they can be recognized and loaded when running your application.

Steps to rectify (if running from command prompt) Step 1- Copy the ojdbc6 jar file from C:\\oraclexe\\app\\oracle\\product\\11.2.0\\server\\jdbc\\lib (Note- this path may differ as per the installation).

Step 2- Paste the ojdbc6 jar file in the Location C:\\Program Files\\Java\\jre1.8.0_45\\lib\\ext (Note- this path may differ as per the installation).

Step 3- Now run the programme java -cp . . It should successfully run without any error.
