I get some more elements on my getCollectionByQuery problem.
It seems that elements of the Collection I get are not valid to be casted by my class.
If I change to put an Iterator on the Collection it works good as soon I don't try to cast to my Objects.
Does anybody can help me ? I am realy stuck.

I change the code to :
System.out.println("Send COLLECTIONQUERY MGT ");
Collection results = (Collection)broker.getCollectionByQuery(listQuery);
//System.out.println("Get COLLECTIONQUERY MGT Rows : " + results.size());
System.out.println("Get COLLECTIONQUERY MGT Rows : INCONNU");
Iterator iter = results.iterator();
Collection acc = new Vector();
System.out.println("Get COLLECTIONQUERY ojbIterator get ");
MGT_Request tmpReq = new MGT_Request();
System.out.println("Get COLLECTIONQUERY ojbIterator iter");
while (iter.hasNext())
{
acc.add(iter.next());
}
System.out.println("Get COLLECTIONQUERY ojbIterator done ");
MGT_Request[] resArray = (MGT_Request[])acc.toArray(emptyArray);
System.out.println("Get COLLECTIONQUERY toArray done ");
And I got the error message :
Send COLLECTIONQUERY MGT
Get COLLECTIONQUERY MGT Rows : INCONNU
Get COLLECTIONQUERY ojbIterator get
Get COLLECTIONQUERY ojbIterator iter
Get COLLECTIONQUERY ojbIterator done

Hi
I have some problem using getCollectionByQuery.
Here is the peace of Code :
System.out.println("Send COLLECTIONQUERY MGT ");
Collection results = (Collection)broker.getCollectionByQuery(listQuery);
System.out.println("Get COLLECTIONQUERY MGT Rows : " + results.size());
MGT_Request[] resArray = (MGT_Request[])results.toArray(emptyArray);
System.out.println("Get COLLECTIONQUERY toArray done ");
I get this trace :
Send COLLECTIONQUERY MGT
Get COLLECTIONQUERY MGT Rows : 2

I have 2 records in my test table, so the size is good.
But methods of Collection to extract objects from the Collection : Iterator, toArray seems to have problem with the results Collection.
When using the pb broker with getObjectByQuery on the same table and same object it is working good.
I am using db-ojb-1.0.rc4
Can anybody help me, I turn alone this problem from one day and get no progress.
