 <html> <body> <% try { SessionFactory sf= new Configuration().configure().buildSessionFactory(); Session s= sf.openSession(); Query e=s.createQuery("select u.*, d.* from Units u,Depts d outer join d.deptId=u.depts"); Iterator i= e.iterate(); out.println("<table>"); while(i.hasNext()) { Units l= (Units)i.next(); Depts v= (Depts)i.next();; out.println("<tr><th>"+l.getUnitId()); out.println("<th>"+v.getDeptName()); out.println("<th>"+l.getUnitName()); } } catch (Exception he) { he.printStackTrace();} %> </body> </html>
