What should I do? The values are not going in the database.
This is the log file of launch4j:

The database driver can not be found. You need to specify to launch4j all the dependencies it is required to include in the class path to Java. How to do that is another question — MadProgrammer, Jan 06 '13 at 08:15

I have added the mysql-connector-java-5.0.8-bin.jar in the classpath. But its still not working. I also tried adding the classpath in the launch4j itself, but still it shows the same error. :( – user1502308 Jan 06 '13 at 08:26
are you run the jar file without make exe? – Alya'a Gamal Jan 06 '13 at 08:48
I have made the exe file using launch4j and now I am trying to execute it. – user1502308 Jan 06 '13 at 08:58
