[QVTO] More information on errors; Maybe corrupt meta models [message #96134]

Hello everyone,

I've got a problem launching a transformation.
Is there a way to display the transformation parsing errors? I only get
the number of errors...
Is there a way to check if there are errors in the metamodel I use? I'm
guessing there is the root of the errors, since adding the missing Ns URI
cutted my error count down from 16 to 4.

PS: I'm launching the transformation from Java code by using the
QvtoTransformationHelper.

Here's the error message:

org.eclipse.core.runtime.CoreException: Error: Failed to parse
transformation 'deployed://MSC/transformation1.qvto', 4 error(s) found.

Hi Michael ,

The org.eclipse.core.runtime.CoreException threw by method
executeTransformation(..) contains MultiStatus with all errors being
found. Check for CoreException.getStatus().isMultiStatus() and use
getStatus().getChildren().

I assume that deployed transformation 'MSC/transformation1.qvto' was
checked (compiled and launched) so the problem is very likely relates to
MM configuration issues.

Regards,
Sergey.

Hi Sergey,

thanks for your Answer. Unfortunately the CoreException, thrown by
executeTransformation(), does not contain a MultiStatus in my case.
Here's my error handling:

catch (CoreException e) {
if (e.getStatus().isMultiStatus()){
for (IStatus item: e.getStatus().getChildren()) {
System.out.println(item.toString());
}
}
}

Is there a way to validate my MM configuration? Are there important
configuration parameters I may have forgot?

Regards,
Michael

Interesting.. What version of QVTO do you use?

I've just checked with 2.0.0M3 build the following:

try {
new QvtoTransformationHelper(scriptUri).executeTransformation(.. )
}
catch (CoreException e) {
if (e.getStatus().isMultiStatus()){
for (IStatus item: e.getStatus().getChildren()) {
System.out.println(item.toString());
}
}

and got several strings dumped.

Latest 1.0.1 should also support that.

In case you use metamodel from workspace it should be reachable in
target platform by the same URI. You can check deployed MM with
Window/Show View/Operational QVT/Metamodel Explorer browser.

Of course diagnostics messages from executeTransformation(..) would help
a lot ;)

Hi Sergey,

I found the cause for the 4 error messages now. In my transformation, I
referenced the modeltypes with:

modeltype msc uses "platform:/resource/MSC/msc.ecore";
modeltype PN uses "platform:/resource/MSC/PN.ecore";

I changed that to the Ns URIs which I specified in the metamodel
properties:

modeltype msc uses "http://msc/1.0";
modeltype PN uses "http://PN/1.0";

Now the transformation is reading the input model correctly. Unfortunately
it seems that the output model is not registered:

Status ERROR: org.eclipse.m2m.qvt.oml.runtime code=1 Line 5: Failed to
resolve metamodel 'http://PN/1.0' null

How can I register the metamodel, so it is usable in the plugin?

P.S.: I can now use MultiStatus Error Messages. I updated everything :-).

Thanks for the help, Sergey!

Hi Michael ,

Reported error implies that model for URI "http://PN/1.0" can't be
found. Try to use 'org.eclipse.emf.ecore.dynamic_package' extension
point to register your .ecore model for target platform.

Also check registered MM in target platform with "Window/Show
View/Operational QVT/Metamodel Explorer" browser.

Regards,
Sergey.

Thank you very much, Sergey!
I fixed all my issues!

But now I have another problem...
Is there a way to create the following construct in a qvto transformation
with ecore metamodels?

<tag>
plain text
</tag>

I would need this because my output model is needed as input for another
tool, which accepts xml input. In xml this type of input is allowed. The
question is,
can it be created in Ecore or by using QVTO respectively?

Regards,
Michael

Hi Michael,

This is out of the QVTo scope, however you might want to take a look at
custom serialization in EMF.

QVTo can save the output model into a resource of a given uri, which
should allow for selecting a specific resource factory and customize the
model
serialization.

Hello,

thanks for the tip with the custom serialization. I'd have rather liked to
solve this issue with QVT but this solution is also satifying. Does anyone
know if it is possible to do this with ATL?

Michael
