I have a XMI file that is the implementation of a aadl model from the OSATE software. This file is a .aaxl2 model. First I try to open this file in Eclipse Epsilun with the open with "Sample Reflective Ecore Model Editor" in order to get the ecore model from that .aaxl2. but I always get the following error:

"org.eclipse.emf.ecore.xmi.IllegalValueException: Value 'org.eclipse.emf.ecore.impl.DynamicEObjectImpl@63112b (eProxyURI: platform:/resource/ClientServer.aadl#ClientServer.ClientServer.impl eClass: org.eclipse.emf.ecore.impl.EClassImpl@117e7b16 (name: SystemImplementation) (instanceClassName: null) (abstract: false, interface: false))' is not legal.

I try to do it programatically but when I excecute the following code to load the resource from a URI 

  Resource resource = this.resourceSet.getResource(URI.createFileURI(modelUri), true);
  resource.load(null);


I got the following error:

Error: org.eclipse.emf.ecore.xmi.PackageNotFoundException: Package with uri 'http://aadl.info/AADL/2.0/instance' not found. (file:/mnt/DATA/00-GSSI/00-WORK/EXAMPLE/output-processing/xmi/0_models-repo_SecuritySystem_with_devices_Instance.aaxl2, 2, 287)

	at org.eclipse.emf.ecore.resource.impl.ResourceSetImpl.getResource(ResourceSetImpl.java:406)


Its there is a way to perform this ?

Is the generated model with nsURI http://aadl.info/AADL/2.0/instance installed in your IDE?

Yes it is
this is the XML model

<?xml version="1.0" encoding="ASCII"?>
<instance:SystemInstance xmi:version="2.0"
  xmlns:xmi="http://www.omg.org/XMI"
  xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance"
  xmlns:aadl2="http://aadl.info/AADL/2.0"
  xmlns:instance="http://aadl.info/AADL/2.0/instance" name="ClientServer_impl_Instance" category="system">
  <systemOperationMode name="No Modes"/>
  <componentImplementation xsi:type="aadl2:SystemImplementation" href="../ClientServer.aadl#ClientServer.ClientServer.impl"/>
</instance:SystemInstance>

It's really hard to "debug" problems with little snips. The use of org.eclipse.emf.ecore.impl.DynamicEObjectImpl suggests that a generated model was not found. The programmatic example suggests that the generate package is not available, if you are running stand-alone, that package hasn't initialized itself. If your question is more Epsilon related, it might be better to ask on their specific forum:
