Convert Different Date Types to Oracle.jbo.domain.Date format

Below code help us to Change Different  Date to JBO Date format.

Calendar cal=Calendar.getInstance();
java.util.Date utilDate=   cal.getTime();      //will  return  Sysdate.
java.sql.Date sqlDate1 = new java.sql.Date(utilDate.getTime());
oracle.jbo.domain.Date jboDate = new oracle.jbo.domain.Date(sqlDate1);
