[JBoss-user] EJBQL problem

[Davide Pozza]

Hi,
I have a problem with an EjbQl: on my scenario, there are 2 entity
beans:
Bean1 and Bean2. There is a unidirectional relation between Bean2 and
Bean1 (M:1).

On my Bean2 I have an EjbQl (findXXX) returning a Collection, like this:

SELECT DISTINCT o.bean1 FROM  bean2 AS o WHERE bean2.bean1.code=?1

When I try to cicle on the collection to retrieve every single element,
a ClassCastException is thrown:

example:

//-->BEGIN<--

// we are on a session facade........

Collection all = Bean2LocalHome.findXXX(code);
Iterator itr = all.iterator();
while (itr.hasNext()){
    Bean1 bean1 = (Bean1)itr.next();//--> ClassCastException!!!!!
    .....
}

//-->END<--

I don't understand: the finder is defined on Bean2 but it should return
a Bean1 collection...or not ?

Thanks 

Davide
