Code:
package events;

This class not exists in documentation of sun:
Sun 1.5.0
Sun 1.4.2
Gnu Classpath

1. If I'll install gnu-classpath it'll be OK?
2. If(1.getAnswer()) {
Why do you use classes which is not in standart api?
} else {
What's wrong?
}

Regards.

Well.
I've read it(both FAQ and lib/_README.txt[1]).
When I use gnu-classpath evrything is OK(there are new row in mysql ect.)
Quote:
I get a ClassNotFoundException or NoClassDefFoundError

You are missing a third-party library Hibernate needs, check lib/README.txt in the Hibernate distribution. Another much more exotic reason might be a static initializer block of one of the needed classes (error during load) or a security-related issue (policy doesn't allow loading).
