Getting the exception:

With-clause referenced two different from-clause elements

When executing the query below with the following entities:

@Entity
public class A {

    @Id
    private Long id;

    @Column(name = "A_ID")
    private Long aId;

    @ManyToOne(fetch=FetchType.LAZY)
    @JoinColumn(name = "A_ID")
    private B b;
}

@Entity
public class B {

    @Id
    private Long id;

    @OneToMany(fetch=FetchType.LAZY, cascade=CascadeType.ALL)
    @JoinColumn(name="C_ID" , referencedColumnName="ID")
    private List<C> c;
}

@Entity
public class C {

    @Id
    private Long id;

    @Column(name="C_ID")
    private Long cId;

    @Column
    private String addType;
}

My HQL Query is: 

SELECT * FROM A a 
INNER JOIN a.b b ON a.aId=b.id 
LEFT OUTER JOIN b.c c ON b.id=c.cId AND c.addType='PermanentAddress' 
LEFT OUTER JOIN b.c d ON b.id=d.cId AND d.addType='ResidentialAddress'
LEFT OUTER JOIN b.c e ON b.id=e.cId AND e.addType='OfficeAddress'
WHERE a.id  =:id

The exception that I get is:

You don't need the ON clauses in your query. Hibernate does automatically link the models.

You don't need the ON clauses and conditions in your query, since you only use the FK, which is implicit anyway.

Try this:

SELECT * 
FROM A a
INNER JOIN a.b b
LEFT OUTER JOIN b.c c WITH c.addType='PermanentAddress' 
LEFT OUTER JOIN b.c d WITH d.addType='ResidentialAddress'
LEFT OUTER JOIN b.c e WITH e.addType='OfficeAddress'
WHERE a.id  =:id
