have you set the enoviornment variable if not then beacuse
of this the driver can not be load
because which you path
Class.forName
("oracle.jdbc.driver.OracleDriver");
in Class.forName("String" )
compiler search it out in bin/lib of jre or jre bin/lib/ext
so please check it out because of it this excption commonly
come
because if some one used Mysql and i did in past i got thsi
exception because it didn't set the Classpath for connection.jar
so do it getridof this thing

(this is for oracle 11g)
c:\>set
classpath=D:\app\Deepak\product\11.2.0\dbhome_1\oui\jlib\classes12.jar;.;
this sets ur classpath teprorily for that session
now run the command for checking that the classpath is seted
properly.
c:\>java oracle.jdbc.driver.OracleDriver
Exception in thread "main" java.lang.NoSuchMethodError: main
if this is shown then now u can run ur program.
