Hibernate LeftOuter join HQL

This is my left join hql query. After executing this code i am getting list size. But unable cast object to respective pojo class.

Query query=session.createQuery("from BwClientdetails clie开发者_JAVA百科nt left join client.bwClientAllocations");

System.out.println(">>>"+query.list().size());
List<BwClientdetails> list=query.list();
for(int i=0;i<list.size();i++){
   BwClientdetails bc=list.get(i);
   System.out.println(bc.getClientid());
}

I am getting below error:

java.lang.ClassCastException: [Ljava.lang.Object; cannot be cast to org.bluewhale.model.BwClientdetails
        at testapplication.Main.getClients(Main.java:364)
        at testapplication.Main.main(Main.java:54)

By not specifing a Select case, the result of your query is an Array of BwClientdetails, bwClientAllocations. Adding Select client in front of the query should solve your problem

Select client from  BwClientdetails  client left  join client.bwClientAllocations

or replacing your for by

for(int i=0;i<list.size();i++){
   BwClientdetails bc=list.get(i)[0];
   System.out.println(bc.getClientid());
}

It's a best practice to alway specify a where clause, it is even part of the JPA spec
