Toplink expression - using complex in clause

Question

We are trying to build an toplink expression in java that would produce the following where clause:
where (settlement_id, retailer_id, site_id, end_read_datetime, txn_datetime)
     in (select settlement_id, retailer_id, site_id, end_read_datetime, max(txn_datetime)
               from tlsa_dim
     where end_read_datetime
     BETWEEN to_date('1/1/2002 00:00:01','mm/dd/yyyy hh24:mi:ss')
                    AND to_date('1/9/2002 00:00:00','mm/dd/yyyy hh24:mi:ss')
               and site_id = '0040473041023'
          group by settlement_id, retailer_id, site_id, end_read_datetime )
We have created a reportquery to represent the internal sub query, but
cannot seem to find how to tell the ExpressionBuilder to get 5 fields together
before the .in(reportQuery).
Anyone have any ideas?          
here is our java code
public static ReportQuery getReportQueryForSiteIdAndEffectiveDateRangeAndMaxHistoricalStartDate() throws DataIntegrityException {
ExpressionBuilder aBuilder = new ExpressionBuilder();
ReportQuery query = new ReportQuery(aBuilder);
query.setReferenceClass(Dim.class);
query.addAttribute("settlementId", aBuilder.get("settlementId"));
query.addAttribute("retailerId", aBuilder.get("retailerId"));
query.addAttribute("siteId", aBuilder.get("siteId"));
query.addAttribute("endReadDateTime", aBuilder.get("endReadDateTime"));
query.addMaximum("max-txndatetime", aBuilder.get("historicalStartDate"));
query.setSelectionCriteria(equalsSiteId.and(greaterThanEqualtoEffectiveStart.and(lessThanEqualtoEffectiveEnd)));
query.addGrouping(aBuilder.get("settlementId"));
query.addGrouping(aBuilder.get("retailerId"));
query.addGrouping(aBuilder.get("siteId"));
query.addGrouping(aBuilder.get("endReadDateTime"));
// Vector reports = (Vector) session.executeQuery(query);
return query;
public static Expression forSiteIdAndEffectiveDateRangeAndMaxHistoricalStartDate(String siteId, DateInterval effectiveDateInterval) throws DataIntegrityException {
ExpressionBuilder aBuilder = new ExpressionBuilder();
Expression greaterThanEqualtoEffectiveStart = aBuilder.get("endReadDateTime").greaterThanEqual(effectiveDateInterval.getStartDate());
Expression lessThanEqualtoEffectiveEnd = aBuilder.get("endReadDateTime").lessThanEqual(effectiveDateInterval.getEndDate());
Vector parameterVector = new Vector();
// trying a vector, but no luck
parameterVector.addElement(aBuilder.get("settlementId"));
parameterVector.addElement(aBuilder.get("retailerId"));
parameterVector.addElement(aBuilder.get("siteId"));
parameterVector.addElement(aBuilder.get("endReadDateTime"));
parameterVector.addElement(aBuilder.get("historicalDateRange").get("historicalStartDate"));
Expression inMaxGroup = aBuilder.get(parameterVector).in(getReportQueryForSiteIdAndEffectiveDateRangeAndMaxHistoricalStartDate());
Expression equalsSiteid = forSiteId(aBuilder, aSiteId);
return equalsSiteid.and(inMaxGroup);
public static Expression forSiteId(ExpressionBuilder aBuilder, String aSiteId){
Expression equalsSiteId = aBuilder.get("siteId").equalsIgnoreCase(aSiteId);
return equalsSiteId;

There is no expression support for this. You'll have to use SQL.
Here is a thread of an example using Having with report queries.
