PageBean Demo:

 
 // FROM Clause; optional
 // If use EclipseLink is required!
 pb.setSelect(" select new com.company.ssh.entity.Account(ac.accountid, ac.qxname) ");
 // FROM Clause Entity Name; rquired
 pb.setEntityName("Account ac");
 // Page Number; optional; default is 1
 pb.setPageNo(1);
 // Rows per page; optional; default is 10
 pb.setRowsPerPage(4);
 // WHERE Clause; optional; default is ''
 pb.setCondition(" and ac.accountid > 2");
 // Append where clause condition; optional; default is ''
 // pb.addCondition(" and name='A'");
 // SortName; optional; default is ''
 pb.setSort("ac.accountid");
 // SortOrder; optional; default is 'asc'
 pb.setSortOrder("desc");
 
 // Immediate use this query
 // data query
 // pb.setQuery("select ac from Account ac where ac.accountid > =10 and ac.accountid < 1000");
 // total query
 // pb.setCountQuery("select count(1) from Account ac where ac.accountid > =10 and ac.accountid < 1000");
 
 // Execute pagination quries
 commonDAO.findByPage(pb);
 
 // Pagination data
 System.out.println(pb.getData());
 System.out.println(pb.getPageNo());
 System.out.println(pb.getRowsPerPage());
 System.out.println(pb.getRowsCount());
 System.out.println(pb.getPageTotal());
