Hi,
I am a slide developer (jakarta slide). I am concerned because
jakarta slide build fails in Gump.
One of the errors is due to the following line in
org.apache.slide.store.ojb.property.ElementListPropertyHandler [1] :
QueryByCriteria query = new QueryByCriteria
(propertyPeer);
From the log of the org.apache.ojb.broker.query.QueryByCriteria
class (or now interface) [2], the constructor used above was
removed 2 years and 5 months ago. [3]
OJB trunk is unstable OJB 2.x (Criteria api based on interfaces).
The OJB_1_0_RELEASE branch is the stable upcoming OJB 1.0.5.
slide ships with db-ojb version 1.0.1 (yes, this is old).
Could someone kindly suggest how to rewrite the construct above
using the current ojb API ?
based on latest from OJB_1_0_RELEASE branch (1.0.5):
// build query out of all non-null fields
Query query = QueryFactory.newQueryByExample(template);
or
// build query based on object identity (all PK's, other fields
will be ignored)
Query query = QueryFactory.newQuery(template);
or
// use findByIdentity, similar to QueryFactory.newQuery(template)
Identity oid = broker.serviceIdentity().buildIdentity
( PropertyPeer.class, new Long(propertyPeer.getPropertyId()));
propertyPeer = (PropertyPeer) broker.getObjectByIdentity(oid);
(all examples should work with TRUNK sources too)
By the way, why do you lookup the PropertyPeer object immediately
after store?
I am not familiar with this piece of code, I am a new slide
committer, and I am trying to make slide build in gump.
I have committed your first suggestion in slide's svn.
If you want to have a look at the code of slide which interacts with
ojb and suggest improvements, I would be delighted.
Thanks very much for your help.
Best regards,
Antoine

Then I could fix gump, and make slide build against the latest db-
ojb.
Thanks very much,
Antoine
