Hi I have problem with Conteiner Managed Relation.
Environment: JBoss 4.0.4.GA, JDK 1.5.0_07 on WindowsXP + SP2, SQL SERVER 2000
I have two EJBs A and B with container managed bidirectional relation (one ?
many). I am using direct SQL to delete the records for B related with one of
A?s instances.
Later when I call a.getBs(), returned collection is not empty, even if the
entities are removed.
If I get B?s home interface and make b.findByA(PK) the returned collection is
empty.
It seems that the relation is not updated.
Here is a simple snippet.
//This is in Entity A.
|
| public boolean hasInstances()
| {
|
| Collection coll = null;
| try
| {
| BHomeLocal processHome = ? //perform lookup here
| coll = processHome.findByAid(getId());
| }
| catch (NamingException e)
| {
| e.printStackTrace();
| }
| catch (FinderException e)
| {
| e.printStackTrace();
| }
| //Note coll is empty. No B entities found
|
| Collection bCollection = getBs(); //CMR of A
| return (!bCollection.isEmpty());
| //Note that it returns false, and bCollection contains the ids of the
//removed B instancess
| }
If anyone can help to tell is it bug or I am doing wrong that I am using direct
SQL to delete records. 10x
