[news.eclipse.tools.emf] Problem loading XMI resource

[aleshob@xxxxxxxx (Abdel )]

Hi all,
I have an xmi file  that I generated from an ecore model using the ecore 
model editor from ecplise
with Create dynamic instance.

the xmi file is shown below :

<?xml version="1.0" encoding="ASCII"?>
<bp:Process  xmlns:xmi="http://www.omg.org/XMI"; 
xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance"; 
xmlns:bp="ca.uqam.latece.bpc4s" xsi:schemaLocation="ca.uqam.latece.bpc4s 
./../../bp.ecore" name="Ordering">
 <succession nextStep="//@ownedCoursePart.0" name="Succession0">
   <previousStep href="../../resource/shared/changePart/Start.xmi#/"/>
   <successorEvent href="../../resource/shared/event/Event_Start.xmi#/"/>
 </succession>
 <succession previousStep="//@ownedCoursePart.0" 
nextStep="//@ownedCoursePart.1" name="Succession1">
   <successorEvent href="../../resource/shared/event/Event_Start.xmi#/"/>
   <predeccesorEvent 
href="../../resource/shared/event/Event_Finish.xmi#/"/>
 </succession>
....
....
</bp:Process>

This file opens without any problem using the eclipse ecore editor.
When I tried to load the same file using the following code,

   	   ResourceSet resourceSet = new ResourceSetImpl();    	  
   	   
resourceSet.getResourceFactoryRegistry().getExtensionToFactoryMap().put("xmi", 
new XMIResourceFactoryImpl());    	   
   	   BpPackage.eINSTANCE.eClass();    	  
   	   URI uri = URI.createURI(fileURI ,true);
   	   Resource resource = resourceSet.getResource(uri, true);

It s giving Feature Not found Exception 

org.eclipse.emf.ecore.resource.impl.ResourceSetImpl$1DiagnosticWrappedException: 
org.eclipse.emf.ecore.xmi.FeatureNotFoundException: Feature 'xmi' not 
found.

If I remove xmlns:xmi="http://www.omg.org/XMI";, It's  giving Feature 'xsi' 
not found..

Any help will be appreciated

Thanks
