The Hibernate resource query does not work in the latest TENEO build [message #118027]

Sat, 12 April 2008 21:03

Eclipse User

I was using up till now the TENEO build from September 2007.
I wanted to take advantage of the latest fixes and loaded the TENEO
I200804102324 build.
With this build my queries do not execute any more.
Here is my code:
Resource.Factory.Registry.INSTANCE.getProtocolToFactoryMap() .put(
"hibernate", new HibernateResourceFactory() {
@Override
public Resource createResource(URI uri) {
return new HibernateResource(uri);
}
});

String queryStr = "hibernate://?dsname=my_database?query1=from part"
URI queryURI = URI.createURI(queryStr); Resource r1 =
resourceSet.createResource (queryURI);

This used to work fine and return all the entries in the table "part".

Withe the new version of TENEO, I get an empty list. I debug trough the
code but code not find where it fails. It just create a new
HibernateResource but has not data.

Any help? What is the difference?

I also loaded the latest EMF M200803121150 and no difference.
Do I need to regenerate the classes from the eCore or can I use the code
that I have (EMF 2.3.1)

Thanks
Yigal

Hi Yigal,
During debugging did you end up in the HibernateResource.loadUsingDefinedQueries method? If so and
the query is correct and it returns an empty list then the issue is related to hibernate (or your
database is empty).
Did you enable hibernate logging? See here for an example log4j file:

Hi Martin,
I never got into a method loadUsingDefinedQueries(). I had logging
turned on and have nothing coming into the log.
I used your log4j.properties (Even thou mine looked the same) and
attaching the result of query that should return 3 rows.
As you see in the log, nothing happens.

Hi Yigal,
Can you put a breakpoint in the HibernateResource.loadResource method? From there you can debug, the
system should go into the loadFromStore method and then into the loadUsingDefinedQueries method (if
there are defined queries in your uri). If you debug this, do you see that a query is executed? Or
what do you see when you debug through the load process?

The log shows that Teneo sees that you want to load using a query.

Martin,
When I debug I did not get into any method called
loadUsingDefinedQueries ().
I'm attaching the log4j part that shows there is no activity.
This query should return 3 lines and I get nothing.

Thanks

Hi Yigal,
Yes I understand, but I am interested to know where the load process then ends up. Just knowing that
you did not get into the loadUsingDefinedQueries method does not give me enough info I am afraid.

Can you put a breakpoint in StoreResource.load and then debug from there?

With defined queries the execution path should:
StoreResource.load
HibernateResource.loadResource
HibernateResource.loadFromStore
HibernateResource.loadUsingDefinedQueries

The HibernateResource.loadResource method logs the message "Loading resource:...", as I don't see it
in your log I am pretty sure that you won't even get there, so where in the StoreResource.load
method does it stop/go away? Do you get into the StoreResource.load method at all?

Martin,
I did set the brake points as you indicated and I never got to any of them.
As I said before nothing is happening and I do not understand it. It
work with the September release of TENEO but not with the current one.
Any changes in the code that I need to look at and maybe add to my code
to make it work again?

Thanks

Hi Yigal,
Hmm something I thought of, a change since the september release is that you have to explicitly call
load on a resource. Before this was done automatically when calling getcontents.

Do you call load somewhere explicitly?

Hi Martin,
As you can see from the code below, I do not call "load" explicitly.
That what I was missing. I added the load() and it works.

What are the option to pass to the load(), do you a document explaining it?

Thanks

Hi Yigal,
There are currently two options which can be passed:
- XMLResource.OPTION_DISABLE_NOTIFY: if set to true then no notifications are send out during load.
This option was used for the gmf integration but this is currently not required anymore for that
integration.
- LOAD_STRATEGY_PARAM: this one is described here:
http://www.elver.org/hibernate/hibernateresources.html#Load+ of+referenced+Objects
