How to handle many-to-many relationship in Hibernate with non-primary key?

I have two objects - Role and Privilege. They have a many-to-many relationship. The code of each object is shown below.
import java.io.Serializable;
import javax.persistence.Column;
import javax.persistence.Entity;
import javax.persistence.Id;
import javax.persistence.Table;
import org.hibernate.annotations.NaturalId;
#Entity
#Table(name = "rml_privilege")
public class RmlPrivilege extends RmlBase implements Serializable{
/**
*
*/
private static final long serialVersionUID = -6810028565979325754L;
public static final String ATTR_NAME = "name";
#Column(name="name",nullable=false,unique=true)
private String name;
#Column(name="description")
private String description;
public String getName() {
return name;
}
public void setName(String privilege) {
this.name = privilege;
}
public String getDescription() {
return description;
}
public void setDescription(String description) {
this.description = description;
}
}
This is the RmlRole file.
import java.util.Set;
import javax.persistence.CascadeType;
import javax.persistence.Column;
import javax.persistence.Entity;
import javax.persistence.FetchType;
import javax.persistence.JoinColumn;
import javax.persistence.JoinTable;
import javax.persistence.ManyToMany;
import javax.persistence.ManyToOne;
import javax.persistence.Table;
#Entity
#Table(name = "rml_role")
public class RmlRole extends RmlBase {
public final static String ATTR_ORG = "org.id";
#Column(name = "name")
private String name;
#Column(name = "description")
private String description;
#ManyToOne(fetch=FetchType.EAGER)
#JoinColumn(name = "organization")
private RmlOrganization organization;
//TODO: In case of LAZY loading, recieve an error
#ManyToMany(cascade=CascadeType.PERSIST,fetch=FetchType.EAGER)
#JoinTable(name = "rml_role_privilege", joinColumns = {
#JoinColumn(name = "role", referencedColumnName = "id") }, inverseJoinColumns = {
#JoinColumn(name = "privilege", referencedColumnName = "name") })
Set<RmlPrivilege> privileges;
public RmlOrganization getOrganization() {
return organization;
}
public void setOrganization(RmlOrganization organization) {
this.organization = organization;
}
public String getName() {
return name;
}
public void setName(String name) {
this.name = name;
}
public String getDescription() {
return description;
}
public void setDescription(String description) {
this.description = description;
}
public Set<RmlPrivilege> getPrivileges() {
return privileges;
}
public void setPrivileges(Set<RmlPrivilege> privileges) {
this.privileges = privileges;
}
}
When I try to get the RmlRole object, I end up getting the "privileges' variable to be blank. I expect the privilege object set to be prepared. I am doing it wrong somewhere but unable to identify.
My Hibernate version: 5

Any help would be highly appreciated.

org.hibernate.WrongClassException: Object [id=null] was not of the specified subclass [com.*.*.Employee]: the class of the given object did not match the class of persistent copy
So not sure why it is giving me this exception and why id is coming as null.

Here we have user as a parent table and (usercredential and address) are child classes in a relationship. When I insert data into tables then every primary key automatically incremented and get the appropriate value while the foreign key (user_id) always remains zero.
https://i.stack.imgur.com/Pivlm.jpg
https://i.stack.imgur.com/fAPth.jpg
https://i.stack.imgur.com/l37mr.jpg
My concern is user_id(foreign key) in child tables should not be null and equals to primary key(user_id) in parent table. Please look for every cascading(delete, update) operation should be implemented well on table.
Further information I am using Json for inserting data into tables.
{
"fName":"sur kumst",
"lName":"adfdf",
"mobile":45106,
"email":"ksusjasd1sd#gmail.com",
"dob":"2012-04-23T18:25:43.511Z",
"address":{
"city":"noida",
"state":"up",
"h_no":"1243"
},
"userCredential":{
"username":"kr0302",
"password":"12345",
"cnfrmpassword":"12345"
}
}

The issue is with the back reference. Hibernate cannot maintain this for you. Say you save your user object. it creates a credential row and generates id. it creates address and id. it updates the cred_id and add_id on the user object and then creates a row for it and generates id and returns that value. at this point you need to add your user object to credential and address and save those again.

It seems you are trying to model two bidirectional relationships:
User <-> UserCredentials and:
User <-> UserAddress.
But what you are really creating the following four relationships:
User -> UserCredentials
User <- UserCredentials
User -> UserAddress
User <- UserAddress
In order to fix this you need to use mappedBy. See this question for reference.

How to map database hql

I have database with 2 simple tables.
cat (category) with id, name.
prod (products) with id, catid, name, price.
I made a query
select pr.id, pr.catid,pr.name, pr.price
FROM prod pr, cat ct
WHERE pr.catid = ct.id AND ct.name = ?
I noticed problem eariler when I use #JoinColumn(name="catid") in prod class.
Repeated column in mapping for entity: goods.prod column: catid
(should be mapped with insert="false" update="false"
I try to use #JoinColumn(name="catid",insertable = false, updatable = false)
but even with this I have cast error.
Ljava.lang.Object; cannot be cast to goods.prod
How can I map database? And do I need to make changes in simplest SQL?

How Filter data When key attribute is in child Table +spring mvc and hibernate

There are 2 table, Parent is MeetingTypes Child is Meetings they have1 : m mapping
Meeting has releaseID atribute so i want to filter its by releaseID .but problem is, its in Child Table...
If it is Parent Table we can do it simply and it is working
Query query = session.getCurrentSession().createQuery("from MeetingTypes where releaseID= :releaseID");
query.setParameter("releaseID", releaseID);
List list = query.list();
if(list!=null && list.size()>0){
return list;
}else{
return null;
}
I tried it this way
Query query = session.getCurrentSession().createSQLQuery(
"from MeetingTypes mt join mt.Meetings m " +
"where m.releaseID = :releaseID");
query.setParameter("releaseID", releaseID);
return query.list();
But give bellow Erro
com.mysql.jdbc.exceptions.jdbc4.MySQLSyntaxErrorException: You have an error in your SQL syntax; check the manual that corresponds to your MySQL server version for the right syntax to use near 'from MeetingTypes mt join mt.Meetings m where m.releaseID = 192' at

You are using HQL not sql so in hql no keyword like join alternatively you can implement join using objecta.objectb and so on so you have to create your query like below
Query query = session.getCurrentSession().createQuery("FROM MeetingTypes mt WHERE mt.meetings.releases.id = :releaseID");
for more details see the below link
http://docs.jboss.org/hibernate/orm/3.3/reference/en/html/queryhql.html#queryhql-joins-forms

Your HQL query should be like this
Query query = session.getCurrentSession().createQuery("FROM MeetingTypes AS mt WHERE mt.meetings.releases.id = :releaseID");
query.setParameter("releaseID", releaseID);
return query.list();
hope this will solve your problem.
hopefully your Releases Entity something like
#Entity
#Table(name="meetings")
public class Meetings {
#Id
#Column(name="meetings_id")
#GeneratedValue(strategy=GenerationType.AUTO)
private int id;
//setter & getters
}
also you have not mentioned your name parameter in #Table() annotation is your table name is same as class name ?
#Entity
The #Entity annotation is used to mark this class as an Entity bean. So the class should atleast have a package scope no-argument constructor.
#Column
The #Column annotation is used to specify the details of the column to which a field or property will be mapped. If the #Column annotation is not specified by default the property name will be used as the column name.
#Table
The #Table annotation is used to specify the table to persist the data. The name attribute refers to the table name. If #Table annotation is not specified then Hibernate will by default use the class name as the table name.
createQuery() VS createSQLQuery()
createQuery()
Create a new instance of Query for the given HQL query string.
createSQLQuery()
Create a new instance of SQLQuery for the given SQL query string.
