Schema in URL

Hy,

Is it possible to restrict the access to a certain schema in the JDBC
connection url?

I'm asking this because i have a problem that when accessing the names
of the fields of a view through the Metadata object i get not only the
fields that belong to the view i intended to access but also the fields
of the view (with the same name) that belong to another schema in the
database.

Cheers and thanks for the help,
Daniel Campelo
