i want select result 2 sql tables method:

@override     public list<object> getall() {          query query = entitymanager                 .createquery("select a.idaccount, c.firstname, c.lastname, a.dateofcreation, a.bonuspoint account ,customer c c.identity=a.id_customer , a.bonuspoint>=5000 , to_days(now()) - to_days(a.dateofcreation) >=60");         return query.getresultlist();     }

and want display query in datatable use datamodel in managedbean:

public datamodel getdatamodel() {         datamodel.setwrappeddata(giftmanagementremote.getall());         return datamodel;     }

in jsf page, use datatable don't know should put in "var":

<rich:datatable rows="15" id="table" value="#{assigngiftmanagement.datamodel}"             **var**="?????">
