HI: I am using javax.persinstence.EntityManager and javax.persinstence.Query to access postgress table.

I do get a list back from the query (list size > 1)
But, I am having problem to cast my entity object to list object.

Below is my code -

Query q = getEntityManager().createQuery( query string);
java.util.list l = query.getResultList();


What I would need to do is to get the first object from the list and cast to my Entity class.

I am doing something like -

MyUser user = null;
for (Object o : l) {
user = (MyUser) o;
}

I am getting the following ClassCastException -

java.lang.ClassCastException: [Ljava.lang.Object;


Please help.
thanx

Hi shahab
your query string should be looks like this
query string ="from user "

or

select user from User user

When you write your own query like you have, and the list is more than 1 item, you will retrieve a Object[] array. And they again contain strings or something.

So you will need to create a Object[] and cast to that to retrieve the data.
