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.

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);
class-ref="net.enterprise.common.model.contact.CPhoneNumber"/>
class-ref="net.enterprise.common.model.contact.CPostalAddress"/>

Armin,
I removed the dynamic proxy from the class descriptors and every thing
works fine. I have not studied them enough to undertand how to handle
them.
In the upcoming 1.0.4 release it will be possible to use proxy handler
classes based on cglib(enabled via OJB.properties file), these
implementation classes allow the generation of dynamic proxies that do
not require the persistent class to implement an interface.

Hi,
ok, now we have a more detailed error message:
[PersistentField] ERROR: while set field:
[try to set 'object value' in 'target object'

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

Re: IllegalAccess When Setting Field
Hi Chris, which version of OJB do you use? Normally OJB will generate a more detailed error log when field setting fails. Caused by: org.apache.ojb.broker.metadata.MetadataException: IllegalAccess error setting field:contactMech in object:net.enterprise.common.model.party.CPartyContactMech Did you post the whole stack trace with complete error log? regards, Armin Chris Worley wrote: I have now removed proxy="dynamic" from all my class descriptors and I no longer get the exception. 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.
