[Teneo] Can't seem to access objects in store [message #72726]

Fri, 23 February 2007 13:49

Eclipse User

I am not able to access objects in a Teneo data store. I have browsed the
database and the object data is there. After doing a load on the resource
I only seem to have the root object. If I try to access objects contained
by the root I get an object of type HibernatePersistableEList, for example.

Here is the code I run to load the resource...

ResourceSet resSet = new ResourceSetImpl();
Resource res = new HibvernateResource(...uri for .ehb file);
res.load(null);

What is wrong here...?

Thanks,
Mark.

Mark,
Yes this is the Teneo EList implementation. Does the elist contain the contained objects?

Mark,
The lists are normally lazily loaded. So they are empty until you access them explicitly (for
example by doing size()).
You need to debug into the load method of the HibernatePersistableEList to see what is happening.
Also the log will provide a fair amount of detail.

Martin,

I have called .isEmpty() on the lists, this should result in a load as
well, correct.??

I will do the debugging tomorrow and see.

Thanks,
Mark.

Martin,

I am running now with debugging on and and see that when I call .load() on
the resource that it looks like the entire resource is loaded...it has run
for more than 15 minutes. I see objects with attribute values, etc. in the
debug output.

I have stepped into the doLoad() method and see that a call to
delagate.toArray() returns an empty array for the object I have been
trying to load.

If it would help I can send you the debug output, but it is HUGE!!

Mark.

Mark,
If possible can you focus on one such empty elist and then check the model and the mapping hbm
(getMappingXML on the HbDataStore) for that relation? Can you post this part of the model and the
part of the mapping xml?
Can you check if for that association the data in the database is correct (the foreign keys are set)?

Martin,
Here are all the entries for 'facility' in both the ecore and mappingXML
file.
Facility is the object I am trying to load/get from the Echostar object.
Echostar is the root object of the store.

Martin,

Please ignore my other post.

This appears to be a issue with windows vs linux.

I once again moved everthing to a Linux box and everything seems to work,
that is the loading of the object I was having trouble with.

I'm not sure what this means, maybe more to you than me...

I am running the same mysql driver on both the windows and linux machines.

Anything else that is OS specific here.?

Mark.

Mark,
No Teneo does not have any os specific code/handling.
Is it possible that this worked because you started with a new empty database (no tables) on Linux?

Martin,

I started looking at the differences between the windows and linux
machines and found that the version of Teneo was different. On the windows
box I was running 0.7.5, and on the Linux box 0.8.0. I have upgraded the
windows box to 0.8.0 and it works like the Linux box.

I am sorry for the waste of time...

Mark.
