[Teneo] Problems with inherited field [message #92934] Fri, 10 August 2007 09:49 Go to next message

Hi all,

I'm always experiencing problem with Teneo.

I have models that are conformed to a meta model.

The problem is that when I try to deserialize the model from an ecore
file, if I register the meta models packages from the meta models loaded
from an ecore file it works fine and I can deserialize my model.

But when I try to get my meta model from Teneo (assuming that the meta
model getting from Teneo vas previously persisted by taking the meta
model coming from the ecore file), I obtain an Exception :

org.eclipse.emf.ecore.resource.Resource$IOWrappedException: Feature
'val' not found. (file:///C:/eclipse-SDK-3.3-

(SAXXMIHandler.java:76)

....



So, I have seen that the "val" feature that isn't found is an inherited
attribute. And If I remove all the inherited element from my model It
works.


I have also seen that the mapping generated by Teneo for a meta model
are not the same if the meta model come directly from my ecore file or
if it is a meta model persisted with Teneo.
With the same properties for the initialization of the hbdatastore
(inheritance mapping setted to SINGLE_TABLE), the subclasses are not
mapped in the same way :
- when the meta model come from the ecore file only one table is
created for a class hierarchy as it is say on
http://www.elver.org/hibernate/inheritance.html

- when the "same" meta model come from Teneo the mapping create
also tables for the subclasses.


It is a problem for me because I have to do a models and meta models
repository, so I must be able to add/get/remove models corresponding to
meta models that are stored in Teneo (without the ecore files containing
the metamodels). But here the meta models coming from file or coming
from Teneo appears to not being equivalent and it doesn't work...

I'm trying to solve it from a long time but I con't find the solution...


If anyone can help me, I will be very happy.



Thanks,


Guillaume Doux

Hi Guillaume,
If you encounter many problems then (imho) the best approach I can think of is take a small model
and analyze the differences between the xml-serialization and the db-serialization (write the
db-serialized model to an xml file and do a text compare) and then post these differences here in
the newsgroup. I would use several small models each one of them covering a limited set of more
complex part of your real-live models (for example one covering inheritance, one other for several
associations, one for enumerates, one for edatatypes, etc.).

Regarding your specific problem, it seems that the inheritance relations between your eclasses is
not persisted in the database. Because of this:
- the sub eclasses are stored in their own table (as Teneo does not see a supertype)
- the inherited features are not visible in the subeclass (as the subeclass does not have a relation
anymore to its supertype).

Can you check/post the hibernate mapping for the eSuperType and eGenericSuperType feature of the eClass?

Hi again,

I attach the generated mapping for the meta-model coming from the ecore
file (mappingWithModelFromEcoreFile.xml) , the mapping for the meta-model
coming from Teneo (mappingWithModelFromTeneo.xml) , the serialized version
of my meta-model coming from Teneo (debFromTeneo.ecore) and my original
meta-model file (debFile.ecore).

The difference between the 2 ecore file is that in my original meta model,
the subclasses are represented like this :
<eClassifiers xsi:type="ecore:EClass" name="Version"
eSuperTypes="#/1/Field"/>

and in the serialized form coming from Teneo, I have this :
<eClassifiers xsi:type="ecore:EClass" name="Version">
<eGenericSuperTypes eClassifier="ecore:EClass
testdeb.ecore#/1/Field"/>
</eClassifiers>


Thanks,


Guillaume

Hi,
and how does the hbm mapping of the ecore model itself look like? Especially the part around
EClassifier.

I attach the complete mapping file.

Hi,
I retested this and afaics it went fine (see the attached file, this one was read from the db). Your
debFromTeneo.ecore has a view strange sections:
<eClassifiers xsi:type="ecore:EClass" name="Dependancy">
<eGenericSuperTypes eClassifier="ecore:EClass testdeb.ecore#/1/Field"/>
</eClassifiers>
<eClassifiers xsi:type="ecore:EClass" name="package_descriptions">
<eGenericSuperTypes eClassifier="ecore:EClass testdeb.ecore#/1/Field"/>
</eClassifiers>

What I don't understand is where this: ecore:EClass testdeb.ecore#
comes from. In the ecore file, I created, the uri is: /1/Field.

My feeling is that this has something to do with the way you create the resource which reads the
debFromTeneo.ecore (btw, this may not be the problem but hides why it does not work for you).

Also my experience with reading epackages from the db or the filesystem is that it needs to be done
through a resourceset this ensures that the packages are placed in the EPackage registry and that
this registry is used during reading.

Btw, here is the simplified code I use to read the ecore, persist it and read it back. There are a
number of calls to convenience methods (store.beginTransaction etc.) but for the rest it is pretty
simple. This code does not use a resourceset (not required for the tests) but in production code you
should do this. You can try to replicate this simple approach and then check if the output is
incorrect or correct.

{
final Resource fileRes = new XMIResourceImpl();
fileRes.load(this.getClass().getResourceAsStream("debFile.ecore "), Collections.EMPTY_MAP);
store.beginTransaction();
for (Object o : fileRes.getContents()) {
store.store(o);
}
store.commitTransaction();
}
{
store.beginTransaction();
final Resource res = new XMIResourceImpl();
for (Object o : store.getObjects(EPackage.class)) {
res.getContents().add((EObject) o);
}
final OutputStream os = new FileOutputStream("/home/mtaal/mytmp/test.ecore");
res.save(os, Collections.EMPTY_MAP);
store.commitTransaction();
}

Hi,

Before send you the preceding message I have renamed the attached file,
the previous name debFromTeneo.ecore was testdeb.ecore...
But I did not know wy the name of the file is adding here.

I will try your code and tell you If it works...

Thanks,

Guillaume

Hi,

I have try your code, it works fine :)

Once the "ecore:EClass myfile.ecore" removed from the file, all the
problems with the mapping are gone out...

It need more test to see if all works fine, but it seems to be...

thanks a lot !

Hi Guillaume,
If you encounter many problems then (imho) the best approach I can think of is take a small model
and analyze the differences between the xml-serialization and the db-serialization (write the
db-serialized model to an xml file and do a text compare) and then post these differences here in
the newsgroup. I would use several small models each one of them covering a limited set of more
complex part of your real-live models (for example one covering inheritance, one other for several
associations, one for enumerates, one for edatatypes, etc.).

Regarding your specific problem, it seems that the inheritance relations between your eclasses is
not persisted in the database. Because of this:
- the sub eclasses are stored in their own table (as Teneo does not see a supertype)
- the inherited features are not visible in the subeclass (as the subeclass does not have a relation
anymore to its supertype).

Can you check/post the hibernate mapping for the eSuperType and eGenericSuperType feature of the eClass?

Hi again,

I attach the generated mapping for the meta-model coming from the ecore
file (mappingWithModelFromEcoreFile.xml) , the mapping for the meta-model
coming from Teneo (mappingWithModelFromTeneo.xml) , the serialized version
of my meta-model coming from Teneo (debFromTeneo.ecore) and my original
meta-model file (debFile.ecore).

The difference between the 2 ecore file is that in my original meta model,
the subclasses are represented like this :
<eClassifiers xsi:type="ecore:EClass" name="Version"
eSuperTypes="#/1/Field"/>

and in the serialized form coming from Teneo, I have this :
<eClassifiers xsi:type="ecore:EClass" name="Version">
<eGenericSuperTypes eClassifier="ecore:EClass
testdeb.ecore#/1/Field"/>
</eClassifiers>


Thanks,


Guillaume

Hi,
and how does the hbm mapping of the ecore model itself look like? Especially the part around
EClassifier.

I attach the complete mapping file.

Hi,
I retested this and afaics it went fine (see the attached file, this one was read from the db). Your
debFromTeneo.ecore has a view strange sections:
<eClassifiers xsi:type="ecore:EClass" name="Dependancy">
<eGenericSuperTypes eClassifier="ecore:EClass testdeb.ecore#/1/Field"/>
</eClassifiers>
<eClassifiers xsi:type="ecore:EClass" name="package_descriptions">
<eGenericSuperTypes eClassifier="ecore:EClass testdeb.ecore#/1/Field"/>
</eClassifiers>

What I don't understand is where this: ecore:EClass testdeb.ecore#
comes from. In the ecore file, I created, the uri is: /1/Field.

My feeling is that this has something to do with the way you create the resource which reads the
debFromTeneo.ecore (btw, this may not be the problem but hides why it does not work for you).

Also my experience with reading epackages from the db or the filesystem is that it needs to be done
through a resourceset this ensures that the packages are placed in the EPackage registry and that
this registry is used during reading.

Btw, here is the simplified code I use to read the ecore, persist it and read it back. There are a
number of calls to convenience methods (store.beginTransaction etc.) but for the rest it is pretty
simple. This code does not use a resourceset (not required for the tests) but in production code you
should do this. You can try to replicate this simple approach and then check if the output is
incorrect or correct.

{
final Resource fileRes = new XMIResourceImpl();
fileRes.load(this.getClass().getResourceAsStream("debFile.ecore "), Collections.EMPTY_MAP);
store.beginTransaction();
for (Object o : fileRes.getContents()) {
store.store(o);
}
store.commitTransaction();
}
{
store.beginTransaction();
final Resource res = new XMIResourceImpl();
for (Object o : store.getObjects(EPackage.class)) {
res.getContents().add((EObject) o);
}
final OutputStream os = new FileOutputStream("/home/mtaal/mytmp/test.ecore");
res.save(os, Collections.EMPTY_MAP);
store.commitTransaction();
}

Hi,

Before send you the preceding message I have renamed the attached file,
the previous name debFromTeneo.ecore was testdeb.ecore...
But I did not know wy the name of the file is adding here.

I will try your code and tell you If it works...

Thanks,

Guillaume

Hi,

I have try your code, it works fine :)

Once the "ecore:EClass myfile.ecore" removed from the file, all the
problems with the mapping are gone out...

It need more test to see if all works fine, but it seems to be...

thanks a lot !
