I am having problems with finder methods on the home interface returning the correct values. For example i have a Client entity bean setup and a Contact entity bean setup. I have a 1 to many relationship between the two, the client is the 1 and the contact is the many. I am trying to run a simple EJB-QL statement and return all Contact entity objects to work with the data. When I run the query it seems to return the right number of entity beans but they are of the wrong type so when I cast them to the proper type my application fails and throw an exception. After debuging with Eclipse it appears that the entity objects being return are Client entity beans instead of the Contact entity beans which are supossed to be returned. Below is application deployment and query.
For those of you interested the problem I was facing was being stupid and forgetting that finder methods only return the native local of the object. I converted these queries to select methods and used the selcts in the entity bean business method and it worked like a champ.
