Hi, Here's the situation I am faced with.Could anybody analyze the situation and tell me which way to go on this?
We have a Person valueobject mapped to a Person table in the database. We have an Application valueobject mapped to the Application table in the database. In the Person valueobject, we've used X-Doclet tags to define an 1:n relationship to Application valueobjects. That is, a person can have 0 or more applications associated with himself. So, the Person valueobject contains a Collection called allApplications which is mapped to the Application valueobject. Now, I have implemented a search. You may search on attributes that are either related to the Person (such as SSN) or Application (such as date of submission of application). Since a person can contain 0 or more applications, I am searching using a getCollectionByQuery(Person.class, ...) meaning that when I search, my results are a collection of Person objects that match both the person and application related search criteria. [NOTE: I am using "allApplication.dateOfSubmission" type of attributes when I want to create search criteria that relate to the application table and not the person table.] Now, in the search results, I am supposed to display attributes that come from both the Person and the Application tables, so when getting the Application I have to use Person.getAllApplications(). When I do this, I get the ALL the applications belonging to the person. What I want to do is LIMIT the contents of the allApplications Collection to just the applications that satisfy the search criteria. Could you suggest a way out here? Our current implementation is: First query and get the collection of Person valueobjects. Then, query on the Application table and get all applications belonging to this person which satisfy the search criteria pertaining to the application table. Then, set these applications (which have been obtained by a getCollectionByQuery()) to the person's allApplication collection object: aPerson.setAllApplications(getCollectionByQuery()); This means a database call for every person, to retrieve his applications, which suggests that we seem to have something wrong as far as the use of OJB is concerned.
