Name and version of the database you are using:
Firebird 1.5



Every time i put an id-tag with a "<generator class="native"/>" property i get this exception. If i use the login-name as id no problem occurs...

Why?

you want hibernate to generate code for you ? then please but the type on the id tag - otherwise we have a hard time guessing it ;)
