I created a NamedQuery with this sql syntax
SELECT NEW EntityDB.TFattureTotali(t.nIdFattura, SUM(r.nImponibile + r.nQta) ,r.nIvaPercentuale) FROM TFatture t, TFattureR r WHERE t = r.nIdFattura GROUP BY t.nIdFattura,r.nIvaPercentuale HAVING t.nIdFattura = :nIdFattura")
When I execute this query I received this error message:
Exception Description: Syntax error parsing the query [TFattureTotali.TotaleFattura: SELECT NEW EntityDB.TFattureTotali(t.nIdFattura, SUM(r.nImponibile + r.nQta) ,r.nIvaPercentuale) FROM TFatture t, TFattureR r WHERE t = r.nIdFattura GROUP BY t.nIdFattura,r.nIvaPercentuale HAVING t.nIdFattura = :nIdFattura], line 1, column 69: syntax error at [+].
Internal Exception: MismatchedTokenException(89!=82)
It seems that EclipseLink don't accept aritmetics operation in aggregates function

Expressions would be something like:
ExpressionBuilder t = new ExpressionBuilder(TFatture.class);
ExpressionBuilder r = new ExpressionBuilder(TFattureR.class);
ReportQuery query = new ReportQuery(TFattureR.class, r);
query.addSum("nImponibile", ExpressionMath.add(r.get("nImponibile"), r.get("nQta"));
query.addAttribute("nIvaPercentuale", r.get("nIvaPercentuale"));
query.setSelectionCriteria(t.equal(r.get("nIdFattura")));
query.addGrouping(t.get("nIdFattura"));
query.addGrouping(t.get("nIvaPercentuale"));
query.setHavingExpression(t.get("nIdFattura").equal(r.getParameter( "nIdFattura"));
query.addArgument(nIdFattura);
Criteria would be similar, give it a try, and show what you tried if still having problems.
