I want is that I get user name!

Question

Hi,
Below are my two annotated classes, namely, Requisition and User, that represent two tables requisitions and users. What I want is that I get
to get username from users table in my requisition query instead of user id which is stored in the requisitions.request_by.
Table field requisitions.request_by hold the ids of users ,ie, users.id values.
Here are my tables:
     users
               + id int(11)
               username varchar(15)
               password varchar(15)
               role int(11)
               last_login timestamp
     requisitions
               id int(11)
               post varchar(50)
               + request_by int(11)
               platform varchar(50)
               experience_required int(11)
               comments text
               date_requested date
Here is my Query for fetching requsition object in the RequisitionServiceimpl.java
     public List getRequisitions(User loggedInUser){
          Query queryRequsitions = em.createQuery("Select r FROM Requisition as r");
          List list = queryRequsitions.getResultList();          
          return list;     
Below are my two annotated classes Requisition and User:

     public Date getDateRequested() {
          return dateRequested;
     public void setDateRequested(Date dateRequested) {
          this.dateRequested = dateRequested;
// Only Getter for Users Table field username
     public String getUsername() {
          return username;
import javax.persistence.Column;

public Long getId() {

public void setId(Long id) {
this.id = id;
public int getRole() {
return role;
public void setRole(int role){
this.role = role;
Thank you,

I made this changes to Requisition.java and now I can get user name
import java.util.Date;
import javax.persistence.Column;
import javax.persistence.Entity;
import javax.persistence.Id;
import javax.persistence.JoinColumn;
import javax.persistence.OneToOne;
import javax.persistence.Table;
@Table(name="requisitions")
@Entity
public class Requisition {
@Id
private int id;
private String post;
@Column(name = "request_by")
private int requestBy;
private String platform;
@Column(name = "experience_required")
private int experienceRequired;
private String comments;
@Column(name = "date_requested")
private Date dateRequested;
@OneToOne
@JoinColumn( name="request_by", insertable=false, updatable=false)
private User user;
public int getId() {
return id;
public void setId(int id) {
this.id = id;
public String getPost() {
return post;
public void setPost(String post) {
this.post = post;
public int getRequestBy() {
return requestBy;
public void setRequestBy(int requestBy) {
this.requestBy = requestBy;
public String getPlatform() {
return platform;
public void setPlatform(String platform) {
this.platform = platform;
public int getExperienceRequired() {
return experienceRequired;
public void setExperienceRequired(int experienceRequired) {
this.experienceRequired = experienceRequired;
public String getComments() {
return comments;
public void setComments(String comments) {
this.comments = comments;
public Date getDateRequested() {
return dateRequested;
public void setDateRequested(Date dateRequested) {
this.dateRequested = dateRequested;
public User getUser() {
return user;
public void setUser(User user) {
this.user = user;
