cascade-delete: SQL DELETE Statement missing!
I have the following problem:
An "Acl" object contains 0 or more "AclEintrag" objects. I can get a set of AclEintrag objects with the aclEintraege relation. If I delete an entry in this set, the corresponding AclEintrag object should be deleted.
The ejb-jar.xml extract looks like this:
<ejb-relation>
<ejb-relation-name>aclEintrag-acl</ejb-relation-name>
<ejb-relationship-role>
aclEintrag
<ejb-relationship-role-name>AclEintragRelationshipRole</ejb-relationship-role-name>
Many
<cascade-delete />
<relationship-role-source>
aclEintrag
<ejb-name>AclEintrag</ejb-name>
</relationship-role-source>
<cmr-field>
acl
<cmr-field-name>acl</cmr-field-name>
</cmr-field>
</ejb-relationship-role>
<ejb-relationship-role>
acl
<ejb-relationship-role-name>AclRelationshipRole</ejb-relationship-role-name>
One
<relationship-role-source>
acl
<ejb-name>Acl</ejb-name>
</relationship-role-source>
<cmr-field>
aclEintrag
<cmr-field-name>aclEintraege</cmr-field-name>
<cmr-field-type>java.util.Set</cmr-field-type>
</cmr-field>
</ejb-relationship-role>
</ejb-relation>
And the two database tables are defined like this (Oracle 9i server):
CREATE TABLE acleintraege (
ACLEINTRAG_ID INTEGER NOT NULL INITIALLY DEFERRED DEFERRABLE,
ADRESSAT_ID INTEGER NOT NULL INITIALLY DEFERRED DEFERRABLE,
ACL_ID INTEGER NOT NULL INITIALLY DEFERRED DEFERRABLE
)
;
CREATE TABLE acls (
ACL_ID INTEGER NOT NULL INITIALLY DEFERRED DEFERRABLE,
NAME VARCHAR2(50) NOT NULL INITIALLY DEFERRED DEFERRABLE,
TYP INTEGER NOT NULL INITIALLY DEFERRED DEFERRABLE,
EXTERNE_ACL_ID INTEGER
)
;
ALTER TABLE acleintraege
ADD CONSTRAINT PK_ACLEINTRAEGE
PRIMARY KEY (ACLEINTRAG_ID)
;
ALTER TABLE acls
ADD CONSTRAINT PK_ACLS
PRIMARY KEY (ACL_ID)
;
ALTER TABLE acls
ADD CONSTRAINT FK_EXTERNE_ACLS FOREIGN KEY (EXTERNE_ACL_ID)
REFERENCES externeacls (EXTERNE_ACL_ID) INITIALLY DEFERRED DEFERRABLE
;
When I try to delete all AclEintraege objects for an Acl object in a session bean, like the following, the transaction is rolled back:
public void setAclEintraegeForAcl(AclDto aclDto, AclEintragDto[] aclEintraege)
throws RemoteException {
try {
Acl acl = aclHome.findByPrimaryKey(aclDto.getId());
Set ejbAclEintraege = acl.getAclEintraege();
// Alte ACL auslöschen
Iterator i = ejbAclEintraege.iterator();
while ( i.hasNext()) {
AclEintrag aclEintrag = (AclEintrag)i.next();
i.remove();
}
// @todo
}
catch (FinderException ex) {
throw new RemoteException(ex.getMessage());
}
}
The last lines from server.log are the following. It seems that all statements are issued, but not the DELETE statement that is required to remove the AclEintrag object. I think that is has nothing to do with my constraints, because
update acleintraege set acl_id=null where acleintrag_id=2;
delete from acleintraege where acleintrag_id=2;
commit;
works perfectly in SQL-Plus, because of the deferred constraint. What I do not understand is why no DELETE statement is issued by JBoss before committing the transaction:
