Hi there,
I followed the CompleteOCL tutorial to succesfully load an ocl file
"core.ocl" in the Sample Ecore editor for my own EMF-model. Validation
works fine; however, I always have to use the Dialogs to manually load
the registered OCL file.
Now I try to do this programmatically.
I created an OSGi Service that gets informed about all EMF-Models that
get loaded for my Metamodel. In such event I want to programmatically
load the OCL files into the corresponding resource set in Order to
trigger EMF validation just the standard EMF way. (If this is not a good
idea, please correct me!)
I copied the code from
org.eclipse.ocl.xtext.completeocl.ui.commands.LoadCompleteOCLResourceHandler$DeferredLoadDocumentJob.processResources()
// Registering OLC components taken from
//
org.eclipse.ocl.xtext.completeocl.ui.commands.LoadCompleteOCLResourceHandler$DeferredLoadDocumentJob.processResources()
ResourceSet modelResources = model.eResource().getResourceSet();
OCLAdapter oclAdapter = OCLAdapter.getAdapter(modelResources);
CompleteOCLLoader helper = new
CompleteOCLLoader(oclAdapter.getEnvironmentFactory()) {
@Override
protected boolean error(String primaryMessage, String detailMessage) {
LOGGER.error("{} {}", primaryMessage, detailMessage);
return false;
}
};
if (!helper.loadMetamodels()) {
return;
}
//
// Load all the documents
//
for (String uriString : OCL_FILES) {
URI oclURI = URI.createPlatformPluginURI(uriString,false);
try {
if (!helper.loadDocument(oclURI)) {
continue;
}
LOGGER.debug("Register OCL file: {}", oclURI);
} catch (Throwable e) {
LOGGER.error("Error loading OCL-File: {} Message: {}, Exception:
{}", uriString, e.getMessage(), e);
}
}
helper.installPackages();
I added all required dependencies such that this compiles. But I guess
that's not enough.
At helper.loadMetamodels() I get exceptions like
13:24:37.748 [ main] INFO

[...]
At helper.loadDocument(oclURI) I get
Error loading OCL-File: /src/core.ocl Message:
org.xml.sax.SAXParseExceptionpublicId: /src/core.ocl; systemId:
/src/core.ocl; lineNumber: 1; columnNumber: 1; Content ist nicht
zulässig in Prolog., Exception:
org.eclipse.emf.ecore.resource.impl.ResourceSetImpl$1DiagnosticWrappedException:
org.xml.sax.SAXParseExceptionpublicId: /src/core.ocl; systemId:
platform:/src/core.ocl; lineNumber: 1; columnNumber: 1; Content ist
nicht zulässig in Prolog.
I debugged the loadDocument and it ultimately uses an XmiResourceFactory
to load my file "core.ocl" which obviously fails because it's not XML.
So I guess the OCL Resource factory is not registered in the background.
Maybe I am missing some dependencies?
these are the dependencies I use:
org.eclipse.ocl.pivot,
org.eclipse.ui,
org.eclipse.ocl.xtext.base.ui,
org.eclipse.emf.validation.ocl;bundle-version="1.4.0",
org.eclipse.ocl.ecore;bundle-version="3.5.0",
org.slf4j.api;bundle-version="1.7.2",
org.eclipse.ocl.xtext.completeocl,
org.eclipse.e4.ui.workbench;bundle-version="1.3.0",
org.eclipse.e4.core.services;bundle-version="2.0.0",
org.eclipse.e4.core.contexts;bundle-version="1.4.0",
org.eclipse.e4.core.di;bundle-version="1.5.0",
org.eclipse.osgi.services;bundle-version="3.5.0"
Any hints?
Cheers,
Hauke

Hi
Please use the OCL newsgroup/forum for OCL issues.
You might find the org.eclipse.ocl.pivot.complete_ocl_registry extension
point helpful for registering your document sp that it is automatocally
visible in the OCL->Load dialog.
Unfortunately EMF provides no EPackage loading delegate so there is no
hook available to load a Complete OCL document automatically. I don;t
know anything about OSGI services; how do they help?
The file access failure is loilely becuase no ProjectMap has initialized
the path sysnonyms, or because your target model is not in a plugin on
the class path or your plugin registrations are erroneous.
https://wiki.eclipse.org/OCL/New_and_Noteworthy/Mars#SR1 shows a couple
of fixes that might be relevant to you.
Regards
Ed Willink
