Java Database Connectivity (JDBC)

I must apoligise for this age old query in advance.
If this post in not in the right place, again i must apoligise.

Been using java for a while now expecially with netbeans. Recently started executing the jar files created by netbeans.

My jar file holds quite a simple application-> to execute an insert on a particular table within my oracle db. [This application Runs perfectly through NetBeans].
I want to run this jar file from the command prompt using the java -jar [option].

When i run the jar from the prompt i get this whole spiel(Story) from java:
java.lang.ClassNotFoundException: oracle.jdbc.driver.OracleDriver
C:\Documents and Settings\Owner\My Documents\Reciepts\BookClub\dist>java -jar Bo
okClub.jar
java.lang.ClassNotFoundException: oracle.jdbc.driver.OracleDriver

Press ANY key to execute

INSERT INTO Members(member_id, group_id, first_name, last_name, address, town, city, phone_code, phone_num) VALUES(16,30,'Maybe',Someone','Mount Street','Somewhere','Dublin','01','1234567')
java.lang.NullPointerException
at bookclub.toDbms.execute(toDbms.java:48)
at bookclub.Main.main(Main.java:46)
Press any key continue the application

I gather the null pointer exception is comming from the missing drivers!

My Details:

C:\Documents and Settings\Owner>echo %classpath%
c:\oracle\ora92\jdbc\lib\ojdbc14.jar

C:\Documents and Settings\Owner>java -version
java version "1.4.2_04"
Java(TM) 2 Runtime Environment, Standard Edition (build 1.4.2_04-b05)
Java HotSpot(TM) Client VM (build 1.4.2_04-b05, mixed mode)

(all oracle driver classs .jar files are here)
Path=c:\j2sdk1.4.2_04\bin;c:\oracle\ora92\jdbc\lib;C:\oracle\ora92\bin;C:\Program Files\Oracle\jre\1.3.1\bin;C:\Program Files\Oracle\jre\1.1.8\bin;......

If anyone out there can point me in some sort of a direction with this one, be most gratefull.
