Hi

I am a complete newbie at Eclipse and UML 2 plugins. I created an activity model in Rational Software Architect and exported as .emx and also as .uml

I am trying to load either of these file in Eclipse such that I would be able to retrieve the model information programatically.

I followed the "improved" tutorial to load the files at https://bugs.eclipse.org/bugs/attachment.cgi?id=217415.

public static void main(String[] args) {
// TODO Auto-generated method stub
PerfEngine engine = new PerfEngine();
engine.analyze();

}

private void analyze() {

ResourceSet resourceSet1 = new ResourceSetImpl();
UML300ResourcesUtil.init(resourceSet1);

URI uri1 = URI.createURI("TMS_xmi.xmi");
Model loadedModel1 = (Model) load(resourceSet1, uri1);
System.out.println(loadedModel1);

ResourceSet resourceSet2 = new ResourceSetImpl();
UML300ResourcesUtil.init(resourceSet2);

URI uri2 = URI.createURI("TMS_uml.uml");
Model loadedModel2 = (Model) load(resourceSet2, uri2);
System.out.println(loadedModel2);

}

I am using the functions from the attached .zip file of the tutorial(link given above) but every time I try to run this, I get the following error message:

Exception in thread "main" java.lang.NoClassDefFoundError: org/eclipse/emf/mapping/ecore2xml/Ecore2XMLRegistry

at sun.misc.Launcher$AppClassLoader.loadClass(Unknown Source)
at java.lang.ClassLoader.loadClass(Unknown Source)
... 4 more

I really really would appreciate anyone's help in the above or if there is a simpler way of loading the files. At the end of the day, I wish to traverse the meta-model of input model.

Thanks

Hi,

You need to have the org.eclipse.emf.mapping.ecore2xml plug-in in your
run-time configuration if you are trying to load UML2 3.0 models in a
Juno Eclipse configuration.

But, as you are running this as a java application, you need to have
the org.eclipse.emf.mapping.ecore2xml_<version>.jar on your
application's classpath. (where <version> is just some version
identifier for the EMF release)

HTH,

Christian

Hi Toqeer, Christain

The tutorial was prepared just during the Juno RCs. Further problems
with UML content registrations showed up and are 'finally' fixed in Juno
SR1.

Whether running standalone or not, content type registrations must be in
the local ResourceSet and a *.uml extension registration must be in the
global registry. This happens pretty automatically within Eclipse, and
can now happen fully by calling UMLResourcesUtil.init(localResourceSet).

UML300ResourcesUtil was an attempt to reverse migrate UMLResourcesUtil
from 4.0 to 3.0. It needs updating to reflect abandoning the option of
using only global registries.

The ecore2xml mapping now uses a local ResourceSet with appropriate
local registrations, so if you use a plugin maifest to compute your
classpath it should be easy.

If you are determined to use your own classpath; good luck.

Regards

Hello Folks,

So I tried it with:

private void analyze() {
ResourceSet resourceSet1 = new ResourceSetImpl();
// UML300ResourcesUtil.init(resourceSet1);
UMLResourcesUtil.init(resourceSet1);

ResourceSet resourceSet2 = new ResourceSetImpl();
// UML300ResourcesUtil.init(resourceSet2);
UMLResourcesUtil.init(resourceSet2);

URI uri1 = URI.createURI("TMS_xmi.xmi");
Model loadedModel1 = (Model) UMLUtil.load(resourceSet1, uri1,
UMLPackage.Literals.MODEL);
System.out.println(loadedModel1);

URI uri2 = URI.createURI("TMS_uml.uml");
Model loadedModel2 = (Model) UMLUtil.load(resourceSet2, uri2,
UMLPackage.Literals.MODEL);
System.out.println(loadedModel2);

}

and both outputs return the models as null. Output: null null

-----------------

I tried with the "older but updated" tutorial with init of the UML300ResourceUtil. I forgot to mention this in the initial post that with the UML300ResourceUtil code, I was using the "load" function which came with the tutorial and not the UMLUtil.load
The load function which I used with UML300ResourceUtil was:

public static org.eclipse.uml2.uml.Package load(ResourceSet resourceSet,
URI uri) {
Resource resource = resourceSet.createResource(uri);

try {
resource.load(null);
org.eclipse.uml2.uml.Package package_ = (org.eclipse.uml2.uml.Package) resource
.getContents().get(0);
out("Loaded '" + package_.getQualifiedName() + "' from '" + uri
+ "'.");
return package_;
} catch (IOException ioe) {
err(ioe.getMessage());
return null;

}

}

After adding the external libraries as suggested I resolved the initial errors but now I get the following error:
Exception in thread "main" java.lang.NullPointerException
at perf.PerfEngine.load(PerfEngine.java:81)
at perf.PerfEngine.analyze(PerfEngine.java:66)
at perf.PerfEngine.main(PerfEngine.java:51)

Appreciate any help/hints you may suggest.

Thanks

Toqeer

Hi

You force us to guess at how analyze might be invoked. Please provide a
zipped project if you want detailed help.

I think that RSA is compatible with UML 2.2 or 2.3 therefore you need to use Eclipse 3.7.

Hi

I've checked https://bugs.eclipse.org/bugs/attachment.cgi?id=217415; it
still workd on Kepler M3.

Your code seems to completely omit most of GettingStartedUtils.init();
in particular the URI map settings. You'll find them useful.
