I define my file test.ocl using
completeocl sources (org.eclipse.ocl.examples.xtext.completeocl -> Run As Eclipse Application)

import 'MyEcore.ecore'
package test

context TestClass
...
....


I try after to parse this file using Xtext.
package fr.enseeiht.completeocl.parser;

import java.io.IOException;
import java.util.Map;

import org.eclipse.emf.common.util.URI;
import org.eclipse.emf.ecore.resource.Resource;
import org.eclipse.emf.ecore.resource.ResourceSet;
import org.eclipse.emf.ecore.resource.impl.ResourceSetImpl;
import org.eclipse.emf.ecore.util.EcoreUtil;
import org.eclipse.emf.ecore.xmi.impl.XMIResourceFactoryImpl;
import org.eclipse.ocl.examples.xtext.completeocl.CompleteOCLStandaloneSetup;







public class Parser {

	public static void main(String[] args) throws IOException {

		CompleteOCLStandaloneSetup.doSetup();
		ResourceSet resourceSet = new ResourceSetImpl();
		Resource resource = resourceSet.createResource(URI.createURI(args[0]));
		resource.load(null);
		
		Resource.Factory.Registry reg = Resource.Factory.Registry.INSTANCE;
		Map<String, Object> m = reg.getExtensionToFactoryMap();
		m.put("completeocl", new XMIResourceFactoryImpl());
		
		EcoreUtil.resolveAll(resource); 
		
		Resource resourceAsXmi = resourceSet.createResource(URI.createURI(args[0].substring(0, args[0].length()-4)+".completeOCLCST"));
		resourceAsXmi.getContents().addAll(resource.getContents());
		resourceAsXmi.save(null);
		System.out.println(args[0].substring(0, args[0].length()-5));

	}
}


I get this error

Exception in thread "main" org.eclipse.ocl.examples.pivot.utilities.IllegalLibraryException: No OCL Standard Library content available

	at fr.enseeiht.completeocl.parser.Parser.main(Parser.java:33)


and if I comment this line
//EcoreUtil.resolveAll(resource);


My OCL file is parsed but without resolve cross references:
For example,
the 
import 'SimplePDL.ecore'

is parsed as
 <element xsi:type="pivot:Annotation" href="/location path ...../test.ocl#xtextLink_::0.10.0.6.1.0::2::/1"/>


Can you please help me to resolve this problem

Best regards,
Thanks

Hi,

first you should call getresource and not createresource
which Xtext Version do you use. There is a Bug on Standalone Cross Refs in 2.3.0 that is fixed in 2.3.1

Hi Christian,
Thank you!
Can you give me a parsing code of an example of an xtext file which refers to an ecore metamodel.

Simple add both resources (the ecore and the .xtext file) to the same resourceset with getResource and use Xtext 2.3.1

Hi,
I modify it in like this

public class Parser {

	public static void main(String[] args) throws IOException {

		CompleteOCLStandaloneSetup.doSetup();
		ResourceSet resourceSet = new ResourceSetImpl();
		Resource resource = resourceSet.getResource(URI.createURI(args[0]), true);
		resource.load(null);
		
		Resource resource1 = resourceSet.getResource(URI.createURI("src/MyDSL.ecore"), true);
		resource1.load(null);
		
		Resource.Factory.Registry reg = Resource.Factory.Registry.INSTANCE;
		Map<String, Object> m = reg.getExtensionToFactoryMap();
		m.put("completeocl", new XMIResourceFactoryImpl());
		
		EcoreUtil.resolveAll(resource); 
		
		Resource resourceAsXmi = resourceSet.createResource(URI.createURI(args[0].substring(0, args[0].length()-4)+".completeOCLCST"));
		
		resourceAsXmi.getContents().addAll(resource.getContents());
		resourceAsXmi.save(null);
		System.out.println(args[0].substring(0, args[0].length()-5));

	}
}

but, I have this error

HI,

i dont know the ocl stuff but why do you do this xmi thing?
it seems that there is something missing on the classpath and or in the resourceset.
does this ocl stuff not have any example code for project setup?

Hi,
After this, I will transform the xmi file (the ocl property).

when I comment this line,
//EcoreUtil.resolveAll(resource);

it works but without resolve crosss reference

Still No OCL Standard Library content available points to a missing ocl specific setup

Hi

This is not an Xtext issue. Pleasew use he OCL newsgroup for
OCL-specific questions.

You may look at the OCL JUnit tests for many examples of how to use
Xtext initilaisation, URI intitialisation.

You should never create a resource directly for an Xtext resource.

Regards

Ed Willink
