with jdbc 3.0 you can use  CachedRowSet class, which provide you a
disconnected ResultSet. here's a snippet:

[code]
Statement stmt = con.createStatement();
ResultSet rs =  stmt.executeQuery(
             "SELECT COF_NAME, PRICE FROM COFFEES");
CachedRowSet rset = new CachedRowSet();
crset.populate(rs);
rs.close();
stmt.close();
[/code]

if you can't, you could create a collection of Map, where a map is a
row.
