[JBoss-user] [EJB 3.0] - Re: mapping unidirectional relation with parameterised compo
Hello, Did you try to map your Collection and after add your getProductDescription(int pLangugeId) (and make a while to search the good description for the specified language ?) It's not a very clean solution. I will search for cleaner solution ;) Good luck @soon View the original post : http://www.jboss.com/index.html?module=bbop=viewtopicp=3917621#3917621 Reply to the post : http://www.jboss.com/index.html?module=bbop=postingmode=replyp=3917621 --- This SF.net email is sponsored by: Splunk Inc.

[JBoss-user] [EJB 3.0] - Re: mapping unidirectional relation with parameterised compo
Yes, I managed to set up a OneToMany relation like: public SetDescription getDescriptions(); but this is not what I'm searching for. I dont want to fetch all description-entries for an product, I only need the entry for the specified language.

[JBoss-user] [EJB 3.0] - Re: mapping unidirectional relation with parameterised compo
I think you must use a Session Bean Façade to initialize your Description (by an EJB QL). Why do you think about it ? I think you have already a session bean (to represent a DAO or a service) ? So it would be easy to set the good description for the current language of user for example.

[JBoss-user] [EJB 3.0] - Re: mapping unidirectional relation with parameterised compo
I dont have a session bean at the moment (but should be no problem)
Is there no way to get a method in the Product Class to get the description for
the specified language?
I don't understand how you want to initialize the Description ...
Do you mean that I should add a NamedQuery like this:
| @Entity
| @NamedQuery(name=getProductDescription, queryString=Select d from
Description d where d.language_id = :language_id)
| public class Description{
| ...
| }
|
But in this case I dont have the current Product...
If I choose this:
| @Entity
| @NamedQuery(name=getProductDescription, queryString=Select d from
Description d where d.language_id = :language_id and d.product_id =
:product_id)
| public class Description{
| ...
| }
|
I need both Id's, hmmm, this should be possible.
But there is the next problem: If I set up the Entity like this:
| ...
| @Id private int product_id;
| @Id private int language_id;
| ...
|
the table is set up wiht only 1 PK (e.g. product_id). I thought I only need a
PK-Class for complex PKs (two integer seems not to be complex)
So if I have to set up a PK-Class, can I use the NamedQuery as listed above?
(and do I need a PK-Class for two int-values?)
Thank you so far!
Andreas

[JBoss-user] [EJB 3.0] - Re: mapping unidirectional relation with parameterised compo
Did you try to make 2 relationships in your description POJO ? In hibernate there was ternary Associations : http://www.xylax.net/hibernate/ternary.html I haven't tried this but I think you can define the two relationship and set the primary key with JoinColumn annotation. I am not sure ! Look at this : http://www.goobsoft.com/resin-doc/ejb3/[EMAIL PROTECTED] At the @JoinColumn. If you try it can you tell me if it works ? Thanks.

[JBoss-user] [EJB 3.0] - Re: mapping unidirectional relation with parameterised compo
I want a unidirectional access to the Description - Class, this means, in the
Description - Class there is no variable storing the Product, so I cant create
a ManyToOne mapping.
If I setup following mapping in the Product Class I get only one PK in the
Description Table:
| @OneToMany
| public SetDescription getDescriptions(){
| return ivDescription;
| }
|
...

Yes, I see... You try to use an existing DataBase ... I saw that : http://jroller.com/page/raghukodali?entry=ejb_3_annotations_for_mapping I think it can help you.
