java.lang.ClassNotFoundException: oracle.jdbc.driver.OracleDriver

java.lang.ClassNotFoundException: oracle.jdbc.driver.OracleDriver Exception comes when we try to connect Oracle database from java program and Oracle driver is not available in classpath.

Class.forName("oracle.jdbc.driver.OracleDriver") method loads a class at runtime using Reflection which throws ClassNotFoundException if the class "oracle.jdbc.driver.OracleDriver"is not found.

To resolve this issue, we need to include the ojdbc.jar JAR in application classpath. For Oracle 10g and 11g, these are present in ojdbc6.jar or ojdbc6_g.jar.
