Using of Report Queries may help, I think.
>From /doc/site.html#Report+Queries :
Report queries are used to retrieve row data, not 'real' business
objects. A row is an array of Object. With these queries you can
define what attributes of an object you want to have in the row. The
attribute names may also contain path expressions like
'owner.address.street'. To define the attributes use ReportQuery
#setAttributes(String[] attributes).
The following ReportQuery retrieves the name of the ProductGroup, the
name of the Article etc. for all Articles named like "C%":
Criteria crit = new Criteria();
Collection results = new Vector();
crit.addLike("articleName", "C%");
ReportQueryByCriteria q = QueryFactory.newReportQuery(Article.class, crit);
q.setAttributes(new String[] { "productGroup.groupName","articleId",
"articleName", "price" });
Iterator iter = broker.getReportQueryIteratorByQuery(q);
The ReportQuery returns an Iterator over a Collection of Object[4]
([String, Integer, String, Double]).
