Can't get all Imported Keys from dmd

The following code SHOULD (according to the JDK1.4 docs) get all the
primary keys related to a table's foreign keys, if I read the docs
right. But I get back a ResultSet only containing one (1) key, not two,
as in my table.

Can someone explain this to me? Why won't it return all the keys in the
ResultSet?

Thanks!

ResultSet fkpk = dmd.getImportedKeys("", "", "login");

while (fkpk.next())
{
    System.out.println("PK: " + fkpk.getString("PKTABLE_NAME"));
    System.out.println("\t" + fkpk.getString("PKCOLUMN_NAME"));
    System.out.println("FK: " + fkpk.getString("FKTABLE_NAME"));
    System.out.println("\t" + fkpk.getString("FKCOLUMN_NAME"));
}

System.out.println(" ");

    reminderanswer        varchar(25)
);
create index idxloginid on login(id);
create index idxlogin_memberid on members(id);

Test results:

PK: accesslevels
