Hi,

I have a ecore model with annotations pointing to pivot(http://www.eclipse.org/emf/2002/Ecore/OCL/Pivot). I am trying to instantiate that model and evaluate an ocl expression.

org.eclipse.ocl.examples.pivot.OCL.initialize(null);
org.eclipse.ocl.examples.pivot.OCL newInstance = org.eclipse.ocl.examples.pivot.OCL.newInstance(new PivotEnvironmentFactory(contextModelInstance.eResource().getResourceSet().getPackageRegistry(), new MetaModelManager(contextModelInstance.eResource().getResourceSet()))); org.eclipse.ocl.examples.pivot.helper.OCLHelper oclHelper = newInstance.createOCLHelper();
try {
ExpressionInOcl createQuery = oclHelper.createQuery(expression);
long start = System.currentTimeMillis();
Value evaluate = newInstance.evaluate(context, createQuery);
long end = System.currentTimeMillis();
String print = print(evaluate.asObject());
print+=":::Execution Time = " + ((double)(end-start)/1000) + " Sec";
return print;
} catch (org.eclipse.ocl.examples.pivot.ParserException ex) {
Exceptions.printStackTrace(ex);
}

but i am getting following exception

Caused by: java.lang.ExceptionInInitializerError
at org.eclipse.ocl.examples.pivot.uml.UML2Ecore2Pivot$Factory.<init>(UML2Ecore2Pivot.java:48)
at org.eclipse.ocl.examples.pivot.uml.UML2Ecore2Pivot$Factory.<init>(UML2Ecore2Pivot.java:47)

at org.eclipse.ocl.examples.pivot.manager.MetaModelManager.<clinit>(MetaModelManager.java:386)

on the bold line in my code.

Do you have any idea why is that?

Regards,

Hi

Your earlier message suggested that UML was missing. The Pivot model
prototypes full UML alignment of UML so it uses UML, but it should be
optional. However your snippets provide insufficient detail to deduce
your problem.

Please post something compilable.

Hardly, no function names, no imports no package declarations .....

Compilable requires (zipped) files that compile.

Hi

I'm not clear how you are running to get the exception trace you report,
but in order to run a 'plugin' containing your java code I need to add:

public static void main(String args[]) {
EssentialOCLStandaloneSetup.doSetup();
OCLstdlib.install();
TestPivot tp = new TestPivot();

Regards

Ed Willink

Hi,

Actually i am using netbeans for this code. I have attached all libraries required in netbeans project(org.eclipse.emf.. , org.eclipse.ocl.example....).

Do i need add EssentialOCLStandaloneSetup.doSetup(); and stdlib.install(); even when i am not using xtext?

It is just running TestPivot class like a test case.

thanks for assistance!

Regards,

Hi

I have no current knowledge on NetBeans.

You currently have to use the Xtext-based parser for the new code.

EssentialOCLStandaloneSetup.doSetup()

initialises it.

OCLstdlib.install() registerts an OCL Standard Library which is now
modeled and replaceable.

Regards

Ed

Hi

The message is fairly obvious

jar:file:/C:/project/AbstractModellerPrm/lib/org.eclipse.uml2.uml_4.0.0.v20120130-1013.jar

but I'm afraid that if you want to re-use Eclipse plugins on NetBeans
you are on your own as far as debugging the plugin installation and
visibility.
