Hello,
I am trying to programmatically trigger OCL validation of my EMF model. Everything works well using the Eclipse environment (EMF model editor and instance viewer)
I use this code in my unit tests. After reading some posts in this forum, I added the following OCL initialization code in my setUp() method:
String oclDelegateURI = OCLDelegateDomain.OCL_DELEGATE_URI;
Operation.Internal.InvocationDelegate.Factory.Registry.INSTANCE.put(oclDelegateURI,
new OCLInvocationDelegateFactory.Global());
EStructuralFeature.Internal.SettingDelegate.Factory.Registry.INSTANCE.put(oclDelegateURI,
new OCLSettingDelegateFactory.Global());
EValidator.ValidationDelegate.Registry.INSTANCE.put(oclDelegateURI,
new OCLValidationDelegateFactory.Global());
Then, in my test method i use the following:
// Validate this domain
Diagnostic diag = Diagnostician.INSTANCE.validate(myDomain);
assertNotNull(diag.getChildren());
for (Diagnostic subDiag : diag.getChildren()) {
System.out.println(subDiag.getMessage());
}
I get the following validation diagnostics, which are both correct but the second one reveals that my OCL constraint has not been evaluated:
The feature 'environments' of 'com.xxx.root.impl.DomainImpl@35b57d0b{#//}' with 0 values must have at least 1 values
Unable to find delegate to evaluate the 'atLeastOneFlow' constraint on 'com.xxx.interaction.impl.InteractionTemplateImpl@27cb4b33{#///@interactionTemplates.0}': http://www.eclipse.org/emf/2002/Ecore/OCL/Pivot
Any idea?
Many thanks for your help,
Best Regards,
-- Jean-Baptiste
PS: I am using org.eclipse.ocl-3.2.1, org.eclipse.ocl.ecore-3.2.0, org.eclipse.ocl.common-1.0.2

Hi
You've only provided only half a problem; no repro.
So I can only provide a half a reply; no solution.

Hi
If you set a breakpoint on BasicDiagnostic, you can see that the "An
exception occurred while delegating evaluation of the" occurred because of a
java.lang.NoClassDefFoundError:
org/eclipse/ocl/examples/domain/utilities/DomainUtil
which is nearly the same as
org/eclipse/ocl/examples/domain/elements/DomainElement
Try fixing the classpath.

Hi Ed,
Thx for your email.
I have carefully read the ForumNetiquette as you suggested.
Nevertheless, I have provided you with a zipped project containing the required files for demonstrating my problem which, since the beginning, is about getting some help on how to initialize the OCL framework. I am still struggling at this and was hoping to find some help in doing such an initialization (which, in my opinion, does not seem to be that special) in this forum.
I have added the two previous screenshots for illustrating the exception I have encountered as no stacktrace is being printed anywhere (as far as I know). By the way, there wasn't any stacktrace printed neither for the missing classpath entries and I thank you for creating and commenting the bug your created.
Regarding my initial problem, and as I still would like to use OCL in my project, would it be better (not to waste your time or other contributors' time) to ask for help specifically on a code snippet regarding OCL usage outside of Eclipse ?
If you want me to ask this question in another thread/forum, please feel free.
Thx for your time and help,
With my best regards,
|

Hi
Perthaps I should add "Don't ask follow on question".
When you write "Thanks to your answer, i discovered that many jars were
missing. I attached my updated project zip." I regard the thread as
complete and assu me that nsibnce you have resolved your problem you can
resolve your next one.
You cannot expect me to reread multiple levels of the thread.
Regards
Ed Willink
