This is my MODEL## (MeetingTypes and Meetings has 1 to many) 

package pearson.dashboard.model;

import java.util.List;

import javax.persistence.Column;
import javax.persistence.Entity;
import javax.persistence.FetchType;
import javax.persistence.GeneratedValue;
import javax.persistence.GenerationType;
import javax.persistence.Id;
import javax.persistence.OneToMany;



@Entity
public class MeetingTypes {
    @Id
    @Column
    @GeneratedValue(strategy=GenerationType.AUTO)
    private int meetingTypeID;
    @Column
    private String typeName;
    @OneToMany(mappedBy = "meetingTypes",fetch = FetchType.EAGER)

    private List<Meetings> meetings;
    public List<Meetings> getMeetings() {
        return meetings;
    }

    public void setMeetings(List<Meetings> meetings) {
        this.meetings = meetings;
    }

    public MeetingTypes() {

        // TODO Auto-generated constructor stub
    }

    public MeetingTypes(int meetingTypeID, String typeName
            ) {
        super();
        this.meetingTypeID = meetingTypeID;
        this.typeName = typeName;

    }

    public int getMeetingTypeID() {
        return meetingTypeID;
    }

    public void setMeetingTypeID(int meetingTypeID) {
        this.meetingTypeID = meetingTypeID;
    }

    public String getTypeName() {
        return typeName;
    }

    public void setTypeName(String typeName) {
        this.typeName = typeName;
    }





}
# 
@Controller
public class MeetingTypesController {
    @Autowired
    private MeetingTypeService  meetingTypeService;
    @Autowired
    private MeetingService meetingService;
    @RequestMapping("/detailsPage")
    public String getAllmeeting(Map<String, Object> map){
        map.put("meetingList", meetingTypeService.getAllMeetingTypes());

        return "details";

    }

This part of controller## 

import java.util.List;

import org.hibernate.SessionFactory;
import org.springframework.beans.factory.annotation.Autowired;
import org.springframework.stereotype.Repository;
import org.springframework.transaction.annotation.Transactional;

import pearson.dashboard.dao.MeetingTypeDao;

@Transactional
@Repository
public class MeetingTypeDaoImpl implements MeetingTypeDao  {
    @Autowired
    private SessionFactory sessionFactory;


    public List getAllMeetingTypes() {
        // TODO Auto-generated method stub
        return sessionFactory.getCurrentSession().createQuery("from MeetingTypes").list();
    }

}

This my part of DAO## 

<c:forEach items="${meetingList}" var="meetingType">

        <td>  This from MeetingTypes:  ${meetingType.typeName}</td> 

                  <c:forEach items="meetingType.Meetings" var="meet">

        <td>  This from Meetings:   ${meet.roomName}   </td>        
                  </c:forEach>
</c:forEach>

this VIEW in JSP ##() when i run only fist for reach it is working,but when i run both it give bellow Error..the thing is this the way i did previously ..it worked

I see an error in jsp: meetingType.Meetings in second forEach should be ${meetingType.Meetings} . Here is the corrected version: 

<c:forEach items="${meetingList}" var="meetingType">
    <td>  This from MeetingTypes:  ${meetingType.typeName}</td> 
    <c:forEach items="${meetingType.Meetings}" var="meet">
        <td>  This from Meetings:   ${meet.roomName}   </td>        
    </c:forEach>
</c:forEach>
