Open file with default program

In my example I have pdf file that I want to be opened as soon as it is saved to disk.


public static void openFile(File fileObj)
{
    StringBuilder sb = new StringBuilder();
    sb.append("cmd.exe /C start ");
    sb.append(fileObj.getAbsolutePath());
    System.out.println("openFile: " + sb);
    try
    {
        Runtime.getRuntime().exec(sb.toString());
    }
    catch (IOException e)
    {
        System.out.println("EEExxxccc");
    }
    }


Hibernate -distinct (with disjunction) via criteria

How to write distinct using Hibernate criteria API?

DetachedCriteria crit = DetachedCriteria.forClass(clazz);

Disjunction dis = Restrictions.disjunction(); // OR
dis.add(Restrictions.eq("billType", BillType.RACUN));
dis.add(Restrictions.eq("billType", BillType.STORNO));
crit.add(dis);

crit.setProjection(Projections.distinct(Projections.property("billSubtype")));

Criteria criteria = crit.getExecutableCriteria(getSession());
return crit.list();

select distinct B.BILLSUBTYPE from bill b where (B.BILLTYPE = 'RACUN' or B.BILLTYPE = 'STORNO')
