Please let me know how to correct this problem..

I was reading the spring.xml and then once the beans are instantiated would like to call the DAO method but here the Beans are not being instantiated which is causing this issue..

Answer 1

It says Could not load JDBC driver class [oracle.jdbc.driver.OracleDriver] which means you don't have the JDBC jar on your class path.

If you're using Maven, please note Oracle no longer publish their JDBC to public Maven repos anymore. You'll have to manually download one from their website.
