Hi,
I am very new to Hibernate so require your help,please.
1. I have two tables mst_users and mst_user_role
2. When I insert the record in mst_users the id generated for this table should be stored as user_id (from mst_users) in mst_user_role_map with role_id(from mst_roles)
3. When I try for the following code
Code:
import java.text.DateFormat;
import java.text.SimpleDateFormat;
import java.util.Date;
import java.util.HashSet;
import java.util.Set;

import org.hibernate.Query;
import org.hibernate.Session;
import org.hibernate.Transaction;

import com.prms.model.MstRoles;
import com.prms.model.MstUserRoleMap;
import com.prms.model.MstUsers;
import com.prms.util.SessionFactoryUtil;
import com.sun.org.apache.bcel.internal.generic.GETSTATIC;
import com.sun.org.apache.xerces.internal.impl.xpath.regex.ParseException;


public class test {

   public static void main(String[] args){
      
      Session session = SessionFactoryUtil.currentSession();
      DateFormat date = new SimpleDateFormat("yyyy-mm-dd" );      
      java.util.Date frmDate = null;             
      try {
         frmDate = date.parse("2010-01-27");
         System.out.println("dDate  "+date.format(frmDate));          
         
      } catch (ParseException e) {                
         e.printStackTrace();
      } catch (java.text.ParseException e) {
      // TODO Auto-generated catch block
      e.printStackTrace();
   }
      
      Transaction tx = session.beginTransaction();
      //create the object of user,role,userrolemap and userrolemap set       
      MstRoles mstRoles = new MstRoles();
      MstUsers usersObj = new MstUsers();
      MstUserRoleMap userRoleMapObj = new MstUserRoleMap();      
      Set<MstUserRoleMap> userRoleMap = new HashSet<MstUserRoleMap>();      
      //create the object of user      
      usersObj.setFname("Nitin"); //this.getFname()
      usersObj.setMname("L");
      usersObj.setLname("S");
      usersObj.setShortName("NLS");
      usersObj.setDob(10);
      usersObj.setJoiningDate(10);
      usersObj.setPAddress("P");
      usersObj.setCAddress("P");
      usersObj.setEmail("nls@gmail.com");
      usersObj.setContactNo("2");
      usersObj.setMobile("9");
      usersObj.setUserId("123");
      usersObj.setPassword("a");
      usersObj.setStatus(1);
      usersObj.setOfficeEmailId("a");
//      String selectQuery = ("Select role.id,role.name,role.description,role.status from MstRoles role where role.id = :activeStatus");
//      //Query query = session.createQuery(selectQuery).setString(
//         //   "activeStatus", "37");
//      Query query = session.createQuery(selectQuery).setString(
//            "activeStatus", "37");
      mstRoles.setId(37);
      mstRoles.setName("a");
      mstRoles.setType("t");
      mstRoles.setDescription("description");
      mstRoles.setStatus(1);
System.out.println(mstRoles.getId());
      userRoleMapObj.setAmdDate(new Date());
      userRoleMapObj.setAmduserId(1);
      userRoleMapObj.setMstRoles(mstRoles);
      userRoleMapObj.setMstUsers(usersObj);
      userRoleMapObj.setMstUserRoleMap(userRoleMapObj);
      userRoleMap.add(userRoleMapObj);   
      
      usersObj.setMstUserRoleMaps(userRoleMap);
      session.save(usersObj);   
      session.save(userRoleMapObj);
      tx.commit();
   }
}


I get the null error for set of userRoleMap as the user_role_id (pk of mst_user_role_map) is used in other tables as foreign key. The other tables are not at all usefull at this stage for me then how do I proceed store the user and user role mapping.

Thanks & Regards,

Avadhut Joshi
