Hi,
I am having a problem with an ejbSelect statement that I have written and I can't figure out what I am doing wrong. I really suspect that I'm missing something very fundamental but can't find it. Any help on this is appreciated as it is beginning to wreak my head a little.
In brief:
I have the following select statment:
public abstract Set ejbSelectDialogClustersInQueue(Integer memberPk) throws FinderException;
<![CDATA[
SELECT mdc.dialogCluster
FROM MemberEJB AS m,
IN( m.clusters ) AS mdc
WHERE m.memberPk = ?1
]]>
Clusters is a cmr-field marked as a set. (All the relationships are setup).
If I step through the returned set, the type of the object I get back is $Proxy26 (or some other number). Why is this... and how do I get the actual object i.e. DialogClusterLocal?
EJB layout:
MemberEJB (1 - M) MemberDialogCluster (M - 1) DialogCluster
---
MemberEJB
Set clusters (MemberDialogClusters)
MemberDialogCluster
MemberLocal member
DialogClusterLocal dialogCluster
Date timeCreated
DialogCluster
---
This is very much like an M-N relationship, but implemented as two 1-M relationships. All I want to do is get a list of the DialogClusters (directly) belonging to a particular member.
My test to try and access the returned item looks like this:
Set dialogClusters = ejbSelectDialogClustersInQueue(getMemberPk());
for (Iterator i = dialogClusters.iterator(); i.hasNext(); )
{
System.out.println("Member - Return set type is: " + i.next().getClass().getName() );
}
If I try to cast the objects within the Set to DialogClusterLocal I get a classcastexception.
I am missing something really simple, I know it, but I can't find out what. I have tried this on JBoss 3.0.0 alpha, and just recently on beta with no apparent change.
Many thanks,
Tim
