Re: auto-delete does not work anymore: rc6???

Tue, 30 Mar 2004 03:45:57 -0800

hi armin,


that was a good suggestion! I don't change the meta data at runtime, but it seems that my auto-delete='false' is replaced (because it's now deprecated) with an auto-delete='object',
but it should be replaced with 'none'! well, that what I would excpect ;)

thats what I got:

<reference-descriptor
       name="contact"
       class-ref="at.weberhofer.eusoda.shared.orm.Contact"
       auto-retrieve="true"
       auto-update="object"
       auto-delete="object"
     >
       <foreignkey field-ref="contactId"/>
     </reference-descriptor>

and that is what it should be

 <reference-descriptor
  name="contact"
  auto-retrieve="true"
  auto-update="true"
  auto-delete="false"
  class-ref="at.weberhofer.eusoda.shared.orm.Contact"
>
  <foreignkey field-ref="contactId"/>
</reference-descriptor>

Hi Andreas,

your code seems ok. Do you manipulate metadata at runtime? Maybe the auto-delete flag change at runtime. Can you check this in your deleteValidate(...)-method

Collection ords = broker.getClassDescriptor(Repository.class).getObjectReferenceDescriptors(); 

for(Iterator iterator = ords.iterator(); iterator.hasNext();)
{
   String str = ((ObjectReferenceDescriptor) iterator.next()).toXML();
   System.out.println(str);
}

and check if the auto-delete is really false (false == 17, true == 23)

regards,
Armin

hello armin,

yes, I did replace the repository.dtd.
I just simplified my application source. Here is the client/server code that produce the wrong deletes.
I'm using jboss 3.2.3 and postgresql 7.4.1.
the repository files and the database structure is attached.

it's strange, because I think, the ojb junit testcase should cover this situation, and it's also strange, that no one else complained
thanks,
andreas

ejb code:
/**
* @ejb:interface-method
*/
public void deleteValidate(Class dClass, Criteria crit) throws Exception {
PersistenceBroker broker = getBroker();
Object o = null;
try {
Query query = QueryFactory.newQuery( dClass, crit, false ); o = broker.getObjectByQuery(query);
log.debug("object to delete: "+o);
broker.delete( o );
} catch (PersistenceBrokerException e) {
log.error("object could not be deleted: " + o);
throw new Exception(e);
}
broker.close();
}
client code:
public void deleteValidateClient() {
Criteria crit = new Criteria();
crit.addEqualTo("institution_contact_id", new Integer(1049080));
try {
OJBSessionRemote ojb = OjbUtil.getOJBSessionRemote();
ojb.deleteValidate( Institution_Contact.class, crit );
} catch (OJBLayerExc e) {
e.printStackTrace();
} catch (RemoteException e) {
e.printStackTrace();
} catch (Exception e) {
e.printStackTrace();
}
}

this is the resulting spy.log:
1080640877421|15|0|statement|DELETE FROM institution_contact WHERE institution_contact_id = ? |DELETE FROM institution_contact WHERE institution_contact_id = '1049080'

hello everbody,

today I checked out the rc6 cvs version and did some validation tests on my application.
I found out, that there is something going wrong, when I delete an object.

I have an decomposed n-m relation:

CONTACT --------INSTITUTION_CONTACT ------- INSTITUTION

when I delete an INSTITUTION_CONTACT the related INSTITUTION and the CONTACT are deleted as well!!
I have put an auto-delete=false in my metadata, so I don't see a reason for that action.

here is the metadata for INSTITUTION_CONTACT :

# Locking

# implementation is to be used.

#
# The LockMapClass entry tells OJB which concrete LockMap
# implementation is to be used.
# If OJB is running on multiple concurrent clients it is recommended
# to use the RemoteLockMapImpl. It guarantees to provide
# Lockmanagement across multiple JVMs.
# This Implemenation relies on a Servlet based Lockserver. To use it you have to
# deploy the ojb-lockserver.war into a Servlet engine.
# and you have to set the Property LockServletUrl to point to this servlet.
# (see LockServletUrl section below).
# If OJB is running in a single JVM (e.g. in a desktop app, or in a servlet
# engine) it is save to use the InMemoryLockMapImpl. Using it will result
# in a large performance gain.

#
# The LockTimeout entry defines the maximum time in milliseconds
# that a lock may be hold. Defaults to 60000 = 1 minute
LockTimeout=60000
#
# The ImplicitLocking entry defines if implicit lock acquisition is
# to be used. If set to true OJB implicitely locks objects to ODMG
# transactions after performing OQL queries.
# If implicit locking is used locking objects is recursive, that is
# associated objects are also locked.
# If ImplicitLocking is set to false, no locks are obtained in OQL
# queries and there is also no recursive locking.
ImplicitLocking=true
#ImplicitLocking=false

#
# The LockServletUrl entry points to the Lockserver servlet.
# This Servlet is addressed by all distributed JVMs if the RemoteLockMapImpl
# is used.
LockServletUrl=http://127.0.0.1:8080/ojb-lockserver
#
#
# The LockAssociations entry defines the behaviour for the OJB
# implicit locking feature. If set to WRITE (default) acquiring a write-
# lock on a given object x implies write locks on all objects associated
# to x. If set to READ implicit read-locks are acquired.
# Acquiring a read-lock on x thus allways results in implicit read-locks
# on all associated objects.

# The PersistentFieldClass property defines the implementation class
# for PersistentField attributes used in the OJB MetaData layer.
# By default the best performing attribute/refection based implementation
# is selected (PersistentFieldDirectAccessImpl).
#
# - PersistentFieldDirectAccessImpl
# is a high-speed version of the access strategies.
# It does not cooperate with an AccessController,
# but accesses the fields directly. Persistent
# attributes don't need getters and setters
# and don't have to be declared public or protected
# - PersistentFieldPrivilegedImpl
# Same as above, but does cooperate with AccessController and do not
# suppress the java language access check.
# - PersistentFieldIntrospectorImpl
# uses JavaBeans compliant calls only to access persistent attributes.
# No Reflection is needed. But for each attribute xxx there must be
# public getXxx() and setXxx() methods.
# - PersistentFieldDynaBeanAccessImpl
# implementation used to access a property from a
# org.apache.commons.beanutils.DynaBean.
# - PersistentFieldAutoProxyImpl
# for each field determines upon first access how to access this particular field
# (directly, as a bean, as a dyna bean) and then uses that strategy
