OJB CLOB Support

2005-12-08 Thread Vamsi Atluri 
Hello all,

In our application we use OJBs extensively. However, we have a CLOB field
that needs to be populated within the application. I was trying to find
documentation about OJB's support for *LOB objects at this link:
http://db.apache.org/ojb/docu/howtos/howto-use-lobs.html

However, all I could find was this:

Strategy 1: Using streams for LOB I/O

## to be written #
Strategy 2: Embedding OJB content in Java objects

## to be written #
Querying CLOB content

## to be written #


Is there any documentation out there that explains these concepts?  Any
help is greatly appreciated. Thanks.

Regards,
-Vamsi

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);

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: Class Hints

2005-12-08 Thread Chris Worley 

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.
