I have Fixed it, but I don't know why it is so:
I have changed the URL from
jdbc:firebirdsql:embedded:\projekte$\FIREBIRD\DATABASES\WINDBERG_MANA
GER.GDB
to
jdbc:firebirdsql:embedded:localhost:C:\\FIREBIRD\\DATABASES\\WINDBERG
_MANAGER.GDB
and id runs.
Why I must set localhost?
The explanation from nagypapi was:

> url to your database to the following
> "jdbc:firebirdsql:embedded:drive:/path/to/database"
> egsample: "jdbc:firebirdsql:embedded:c:/data/sexyboy.gdb"
