How to construct a ResultSet from a Collection?

Question

I've found lots of articles/postings describing how to create a Collection given a ResultSet, but I need the
opposite.
Anybody know of code that will create an object with the ResultSet interface that can be constructed (or populated after fact) with a Collection?
Sun's CachedRowSet can't do this unless I'm missing something. Ideally it would have a constructor that took a Collection as a parameter.

public class RowSetExample
public static void main(String args[])
try {                     
// create a new rowset and populate it...
sun.jdbc.rowset.CachedRowSet crs = new sun.jdbc.rowset.CachedRowSet();
sun.jdbc.rowset.RowSetMetaDataImpl rsmdi = new sun.jdbc.rowset.RowSetMetaDataImpl();
int colCount = 2;
rsmdi.setColumnCount(colCount);
rsmdi.setColumnDisplaySize(1, 5);
rsmdi.setColumnName(1, "ID");
rsmdi.setColumnType(1, java.sql.Types.INTEGER);
rsmdi.setColumnTypeName(1, "INTEGER");
rsmdi.setTableName(1, "MY_TABLE");

crs.setMetaData(rsmdi);
java.util.Map map = new java.util.HashMap();
map.put(new Integer(1), "AAA");
map.put(new Integer(2), "BBB");
map.put(new Integer(3), "CCC");
java.util.Iterator iter = map.entrySet().iterator();
while (iter.hasNext()){
java.util.Map.Entry entry = (java.util.Map.Entry) iter.next();
int idx = 0;
crs.moveToInsertRow();
crs.updateObject(1, entry.getKey());
crs.updateObject(2, entry.getValue());
crs.insertRow();
crs.moveToCurrentRow();
crs.beforeFirst();
while (crs.next()){
System.out.print(crs.getObject(1));
System.out.println(": " + crs.getObject(2));
}catch (SQLException ex) {
System.err.println("SQLException: " + ex.getMessage());
