Fixed the problem by adding tags for name and type in the bind-xml and sql
mappings.
However - now I get this:
org.exolab.castor.mapping.MappingException: The attribute set-method="..."
in class castortest.Person accepting/returning object of type int was not
found.

Any clues? The getter-setter-methods are implemented, so that should not be
the problem.
