    org.hibernate.ejb.QueryImpl.setParameter(QueryImpl.java:206)

    id.co.compnet.api.keu.ctl.PendapatanJpaController.getPendapatanByNamaPemohon(PendapatanJpaController.java:209)

    id.co.compnet.cetak.CetakKwitansiDendaMBean.searchByName(CetakKwitansiDendaMBean.java:105)

and this is the line which on PendapatanController.java

line 209 is  q.setParameter("namapemohon", namaPemohon); and this related to my query
