I am having problems in loading the oracle Driver into my compiled (Exported) Jar file.

it works ok as long as it is in classes form, I simply set the class path to both .zip files (classes12.zip , nls_charset.zip) and then through
DriverManager.registerDriver(new oracle.jdbc.OracleDriver());

I am loading the driver..

but as soon as I export my program (make a jar file) I get :


what am I doing wrong ?
