classes, not Classes. Case counts.

And is the pack1 folder created for the package? (Please use better names than pack1.)

Have you followed the steps in the ServletsFaq to diagnose this problem?

Thank you very much Mr.Bear Bibeault.

Errors in HTML will have no effect on whether the servlet will execute or not.

Are the classes associated with this servlet in the servlet engines classpath? If they're not, that engine is going to have difficulty instantiating the servlet.

That's one of the checks in the ServletsFaq; there is no need to repeat it.
