[TEXO][Xcore] Generating JPA Entities from Xcore [message #1220353]

Hi All,

I'm trying to use Xcore together with Texo. After creating Xcore file I've created accompanying ecore file (using EMF Generator Model) as described on Xcore page. From such generated ecore file I try to invoke Texo (i.e. Texo / Generate Model + DAO Code) but then I got error:

Diagnosis of platform:/resource/org.ngo.help.sample.model/model/model.ecore#/
The feature 'eType' of 'platform:/resource/org.ngo.help.sample.model/model/model.ecore#//Library/name' contains an unresolved proxy 'platform:/resource/org.eclipse.emf.ecore/model/Ecore.ecore#//EString'
The feature 'eAttributeType' of 'platform:/resource/org.ngo.help.sample.model/model/model.ecore#//Library/name' contains an unresolved proxy 'platform:/resource/org.eclipse.emf.ecore/model/Ecore.ecore#//EString'

After looking into generated ecore file I see that there are local references to the file system:

<eStructuralFeatures xsi:type="ecore:EAttribute" name="name" unique="false" eType="ecore:EDataType ../../org.eclipse.emf.ecore/model/Ecore.ecore#//EString"/>

And when looking into examples of ecore files provided with Texo, it looks quite different, e.g.:

<eStructuralFeatures xsi:type="ecore:EAttribute" name="name" unique="false" lowerBound="1"
    eType="ecore:EDataType http://www.eclipse.org/emf/2003/XMLType#//String">

I manualy edited ecore file to use these global addresses instead of the local ones and now generation with Texo works. How to force generation of ecore from Xcore file so that it references Ecore model from the global address?

Cheers,
Dominik

Dominik,

I chatted with Martin and I suspect he just needs to use:

resourceSet.getURIConverter().getURIMap().putAll(EcorePlugin.computePlatformURIMap(true));

These models load fine in the Ecore editor and that's what it does...

Ed, Thanks for the reply.

Martin, should I report this to bugzilla? Maybe I can offer a patch then (if I find place(-s) in the code... could take me a while:)).

BTW. seems that there is a similar problem in CDO (see my post from today).

Hi Dominik,
I published a new build with this addition. Can you try it?

I have entered a bugzilla myself for it:
https://bugs.eclipse.org/bugs/show_bug.cgi?id=423904

I have put the XCore/Texo integration on my thought list, it was there already but moved up. It would be really nice to
make that more direct/fluent (directly generate code from xcore for example instead of going through a genmodel).

Yes, sure. Please find my comment in the bugzilla that you've created.

This would be great!

Hi Martin,

I ran into the same issue and tried the newest stable and nightly version, but without luck.

Could you have a second look, please?

Also, I read somewhere in the Texo wiki pages that generating code from an Xcore file already works for you. Do you have any plans to release a version with this change? That would really come in handy. Thank you.

Hi Moritz,
The past days I have picked up the xcore integration, trying to get a working build with improved xcore handling. Xcore
works locally for me, but just not on the build server. I will update the issue when it runs through, am on it.

Hello, I am also experiencing the same issue as described above by Dominik Leszyk.

Is there a work around for this, so that I am able to go from xcore to ecore, to texo?

Thanks and regards

The posts on the forum are automatically synced with the newsgroup, so works fine :-).
