anyone know a good way to return the identity of a row that was just inserted?

if you are talking about MS SQL SERVER....
you should call a stored procedure which does the insert and the last statement in the procedure is
select @@IDENTITY

Another idea that works with oracle(it may be possible in SQLServer too) is to use a select statement to obtain the new identifier. In Oracle the database will give out the next available id (as if it were in an insert statement) then use the id in your insert statement.
Oracle code:
resultset = statement.executeQuery("select sequence.nextVal from dual");
long nextId = resultset.getLong(1);
--> this selects the next
id value from the database. dual is just a dummy table so you can accomplish the select statement.
statement.executeUpdate("insert into table (id, name) values (" + nextId + ", 'Joey Joe Joe Shabadoo')");
