You should have a file called "classes.zip", "classes.jar", "oracle.jar" or something like that containing the driver somewhere in your Oracle distribution.Consult the manual.

Usually they can be found here:/oracle/product/<product version>/libOn Unix which should be similar on Windows

yup this is the path

C:\oracle\product\10.2.0\client_1\jdbc\lib

do i add this directory to the env.variables? or is there anything else i need? btw, is the rest of my env.variables path correct?

first of all find the jar which contains driver class used by u, then put that jar on buildpath.

oh i think i saw it while googling before.It is to put the classes12.jar and ojdbc14.jar to the java classpath (C:\Program Files\Java\jdk1.5.0_11\bin) right?hmmm i have done that but still the same error msg :(

Or. classes12.jar or ojdbc14.jar; the first is working for >= Java 1.2, the latter for Java >= 1.4.

So your classpath should contain (among others) e.g.:

C:\oracle\product\10.2.0\client_1\jdbc\lib\ojdbc14.jar

Hi guys, am having the same problems, I compiled my program and it complied fine, but when I try to run it after setting the necessary classpath, I get an exception Exception in thread "main" java.lang.NoClassDefFoundError: MyClassname

When I copy the classes12.jar to the current working directory, I get an exception

from the Class.forName statement: java.lang.ClassNotFoundException: oracle.jdbc.driver.OracleDriver.

I even t
