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
