hi chris,
please post the sql with and without the hints.

Actually I don't think this problem is directly related to class

but that will be fixed in the next released
previouse email from Armin:
In the next version of OJB this will be fixed (or try the
OJB_1_0_RELEASE branch from CVS) and
CParty party = (CParty) getBroker().getObjectByIdentity(oid);
will always return the correct object instance (CParty,
CPartyGroup or Person) and you can directly cast to the real party type.

I am having a problem with class hints. They do not seem to work
all the time with my configuration. If the PartyContactMech object
is stored in the same instance of the server process that I retreive
it in PartyContactMech.contactMech is populated with an instance of
CPhoneNumber or CPostalAddress. If I try to reteive a records that
were created in a previous instance of the process then
PartyContactMech.contactMechs is populated with an instance of
ContactMech.
Integer partyId = (Integer) getParameter(partyId);
Criteria crit = new Criteria();
crit.addEqualTo(partyId, partyId);
crit.addPathClass(contactMech, CPhoneNumber.class);
Criteria critAddress = new Criteria();
critAddress.addEqualTo(partyId, partyId);
critAddress.addPathClass(contactMech, CPostalAddress.class);
crit.addOrCriteria(critAddress);
Query query = QueryFactory.newQuery(CPartyContactMech.class,
crit);
Collection partyContactMechs = getBroker().getCollectionByQuery(query);
setParameter(partyContactMechs, partyContactMechs);

Re: Class Hints
Jakob,
Ok, I miss understood its purpose. I wanted and instance of PhoneNumber
or PostalAddress, I guess it goes back to the bug Armin mentioned. I
have modified my code to loop through the results and query for the
appropriate table and set it in PartyContactMech.
Thanks for the clarification. I see now in the example that it is
referencing a field in the extended table.
-chris worley
hi chris,
adding a path class makes only sense when you hava a path in your query.
ie:
crit.addEqualTo(contactMech.something, on other thing);
crit.addPathClass(contactMech, CPhoneNumber.class);

Re: IllegalAccess When Setting Field
After doing some testing. I am finding that sometimes I get the exception, sometimes it works and sometimes the contactMech is populated with an instance of CPhoneNumber (which is what i want) and sometimes it just populates with CContactMech. CPhoneNumber extends CContactMech. I have modified the code on the server to use class hints. The only pattern I am finding is that I can retreive the PartyContactMech without an exception if the obejct was created during the life of the server process. If i start the server and retreive one that was not created during the life of the process then I get the exception.

Here is the complete output at the time the service is invoked. For
this I have set all proxies back to dynamic in the class descriptors.
If I comment out the reference to the contactMech the party reference
gets populated just fine. I am not sure what the deail is with the

Seems that OJB try to set the field in a correct way. You declare
CContactMech as dynamic proxy and OJB try to set such an instance in
CPartyContactMech.
Think the field you declare in CPartyContactMech have to be an
Interface if you want to use a normal dynamic proxy in this case

Why did you declare CContactMech class objects as proxy? Wouldn't it
be better to use a proxy-reference for the 1:1 relation between
CPartyContactMech and CContactMech?

Armin,
Here is the complete output at the time the service is invoked. For
this I have set all proxies back to dynamic in the class
descriptors. If I comment out the reference to the contactMech the
party reference gets populated just fine. I am not sure what the
deail is with the ContactMech.

Re: Class Hints
Actually I don't think this problem is directly related to class hints. In a previous thread Armin mentioned to me that there was a but that will be fixed in the next released previouse email from Armin: In the next version of OJB this will be fixed (or try the OJB_1_0_RELEASE branch from CVS) and CParty party = (CParty) getBroker().getObjectByIdentity(oid); will always return the correct object instance (CParty, CPartyGroup or Person) and you can directly cast to the real party type. -chris worley I am having a problem with class hints.

Forgein Key Not Set
I have a problem where the forgein key ids are not set in the object or db after the forgein object has been created. TABLE_A -A_ID TABLE_B -B_ID -A_ID In the mappings tableB has a reference descriptor for tableA TableA tableA = new TableA(); TableB tableB = new TableB(); tableB.setA(tableA); At this point the objects are serialized, sent and recreated on the server. getBroker().store(tableA); getBroker().store(tableB); When I look in the db table_b has the value of 0 for a_id. When getBroker().store(tableA) is executed I can see the a_id set in tableB.tableA.a_id but, I do not see the change in tableB.a_id. When table b is stored the value for a_id remains unset with the value of 0 even though tableB.tableA.a_id has the value set to 1 or whatever it was assigned. -chris worley - To unsubscribe, e-mail: [EMAIL PROTECTED] For additional commands, e-mail: [EMAIL PROTECTED]

ClassCastException with getObjectByIdentity()
In the following code I get a ClassCastException when querying for the
PartyGroup or Person. PartyGroup and Person both extend Party.
Party.partyTypeId will determine if the party is a person or party
group. If the party is one of the two then I want to get the party
group or person object and return it. However, when the code queries a
second time for the person or party group a ClassCastException occurs.
getObjectByIdeneity(...) is retruning an instance of CParty, even though
when the Identity was build I passed CPartyGroup.class as the param no
CParty.class.
If I modify the code not to query for CParty first and just query for
CPartyGroup I will get an instance of CPartyGroup. But, for some reason
by building the CParty identity first the second attempt for CPartyGroup
still returns an instance of CParty. and I have no idea why.
Can anyone shed some light on what is going on and why I continue to get
an instance of CParty and not CPartyGroup or CPerson.
// Find the party
Identity oid = getBroker().serviceIdentity().buildIdentity(CParty.class,
partyId);
CParty party = (CParty) getBroker().getObjectByIdentity(oid);
if (CParty.TYPE_PARTY_GROUP.equals(party.getPartyTypeId()))
{
// Get the Party Group
Identity partyGroupId =
getBroker().serviceIdentity().buildIdentity(CPartyGroup.class, partyId);
// ClastCastException here
CPartyGroup partyGroup = (CPartyGroup)
getBroker().getObjectByIdentity(partyGroupId);

Re: ClassCastException with getObjectByIdentity()
I have found my problem. I was using the extent tag for in the
descriptor for party referencing PartyGroup and Person. After removing
the extent the correct instance is returned.

Which kind of inheritance do you use? In OJB =1.0.3 there is a bug in
retrieve objects using Mapping Classes on Multiple Joined Tables
(see release notes, it's fixed in CVS OJB_1_0_RELEASE branch).
CParty party = (CParty) getBroker().getObjectByIdentity(oid);
This call should return the correct object instance, no need to query
with the correct partyIdType again.
Could you post the metadata mapping for Party, Person, PartyGroup?
Here is the mapping for the tree class. I solved my problem by removing
the extent tags from the party descriptor. You did mention that I
could do this in one query I an interested in knowing how.
