class not found

I am writing a small JPA class which throw an error saying at runtime a Class [oracle.jdbc.OracleDriver] not found.
where can I find the class and how to do installation?

reference:

package com.apress.javaee6.chapter02;

import javax.persistence.*;

public class Main {

/**
	 * @param args
	 */
	public static void main(String[] args) {
		
		Book book = new Book();
		book.setTitle("The Hitchhiker's Guide to the Galaxy");
		book.setPrice(12.5F);
		book.setDescription("Science fiction comedy book");
		book.setIsbn("1-84023-742-2");
		book.setNoOfPage(354);
		book.setIllustrations(false);
		
		EntityManagerFactory emf = Persistence.createEntityManagerFactory("chapter02PU");
		EntityManager em = emf.createEntityManager();
		
		EntityTransaction tx = em.getTransaction();
		tx.begin();
		em.persist(book);
		tx.commit();
		
		em.close();
		emf.close();
		
	}
}

You need to add the Oracle JDBC driver to your classpath. (ojdbc.jar)

You can get the Oracle JDBC driver from an Oracle database installation or from OTN.

I just put the ojdbc6.jar in /WEB-INF/lib and it prompt me another error saying can't get connection from the driver.
I don't know how to add to classpath. could you show me more detail?

Hello, Ryan,
Are you using some kind of IDE like eclipse or Intellij ? Please specify.
BR,

What is the "other error"?

I m using eclipse.
figuring out that many typo in persistence.xml, I've fixed all error.
