No suitable driver
C:\Documents and Settings\sphoortia\Desktop\project>
With this error my pgm exits.
I have made the necessary additions of jar file paths[classes12.zip, ojdbc14.jar ] in the classpath variable. But still it gives the error. Can anyone please help me with this .
Thanks
try
                              //DriverManager.registerDriver (new oracle.jdbc.driver.OracleDriver());
                              String driverName = "oracle.jdbc.driver.OracleDriver";
                              //String driverName = "OracleDriver";
                            try {
                                   Class.forName(driverName);
                              } catch (ClassNotFoundException e) {
                                   e.printStackTrace();
                              }

C:\Documents and

I have made the necessary additions of jar file
paths in the classpath
variable. You can't use the enviroment class path variable with an executable jar.
Nor can you use the command line path class path option.
