Filter CriteriaQuery JPA 2.0 -

-

i making application java 1.6, jsf 2.0, jpa 2.0, primefaces 5.3 on weblogic server 10.3.6

i require implement lazy datatables burden modules , not make filter work.

this load method:

public list<t> load(int first, int pagesize, string sortfield,     sortorder sortorder, map<string, object> filters) { // todo auto-generated method stub try {     list<t> list = new arraylist<t>();      //criteria query     criteriabuilder cb = this.ejbutils.getentitymanagerprivate().getcriteriabuilder();     criteriaquery<t> cq = cb.createquery(entityclass);      //from     root<t> = cq.from(entityclass);      //sort     if(sortfield != null){         if(sortorder == sortorder.ascending){             cq.orderby(cb.asc(from.get(sortfield)));         }else{             cq.orderby(cb.desc(from.get(sortfield)));         }     }      //filters     if(!filters.isempty()){          list<predicate> predicates = new arraylist<predicate>();          (iterator<string> = filters.keyset().iterator(); it.hasnext();) {              string filterproperty = it.next();             object filtervalue = filters.get(filterproperty);                                expression<string> literal = cb.upper(cb.literal((string)filterproperty.touppercase()));              predicates.add(cb.like(literal, string.valueof("%" + filtervalue + "%").touppercase()));          }                        cq.where(predicates.toarray(new predicate[predicates.size()]));                  }         query q = this.ejbutils.getentitymanagerprivate().createquery(cq);      list = q             .setfirstresult(first)             .setmaxresults(pagesize)             .getresultlist();      this.setrowcount(this.ejbutils.count());      return list;   } catch (exception e) {     // todo auto-generated catch block     e.printstacktrace();     return null;   } }

and @ log eclipselink , throws me this

[el fine]: 2016-07-15 11:15:35.415--serversession(1294563329)--connection(1645363733)--thread(thread[[active] executethread: '21' queue: 'weblogic.kernel.default (self-tuning)',5,pooled threads])--select * (select /*+ first_rows / a., rownum rnum (select id a1, action a2, activa a3, fecha_creacion a4, fecha_modificacion a5, nombre a6, usuario_creacion a7, usuario_modificacion a8, id_padre a9 se_opciones upper(?) ?) rownum <= ?) rnum > ? bind => [nombre, %rol%, 10, 0]

then when enter filter in datatable never brings results.

i fixed, replacing

predicates.add(cb.like(literal, string.valueof("%" + filtervalue + "%").touppercase()));

by

predicates.add(cb.like(cb.upper(from.get(filterproperty).as(string.class)), string.valueof("%" + filtervalue + "%").touppercase()));
