You name your Java classes like this ? "barApp" instead of "BarApp" ? That might be the source of error.

Thank you for your reply.The name is same.

This program is working fine in another server, my work is shifting all the files from one server to another server.

Any more suggestion?

thanks

Most likely, that class is not available. Are you sure that you copied all the class files and jars?

And, Christophe has a point -- even though it may work, using non-standard coding conventions makes code surprisingly hard to read. I'd take his suggestion to heart.
