I tried to read the model elements from the fowlloing .uml file:
<?xml version="1.0" encoding="UTF-8"?>
<xmi:XMI xmi:version="2.1" xmlns:xmi="http://schema.omg.org/spec/XMI/2.1" xmlns:uml="http://www.eclipse.org/uml2/3.0.0/UML">
<uml:Model xmi:id="_6HP2ALLqEeC4NenKT57Ftw" name="MyFirstModel"/>
<uml:Class xmi:id="_6HP2AbLqEeC4NenKT57Ftw" name="University">
<ownedAttribute xmi:id="_6HP2ArLqEeC4NenKT57Ftw" name="dept_end" association="_6HP2BrLqEeC4NenKT57Ftw"/>
</uml:Class>
<uml:Class xmi:id="_6HP2A7LqEeC4NenKT57Ftw" name="Department">
<ownedAttribute xmi:id="_6HP2BLLqEeC4NenKT57Ftw" name="address" type="_6HP2A7LqEeC4NenKT57Ftw"/>
<ownedAttribute xmi:id="_6HP2BbLqEeC4NenKT57Ftw" association="_6HP2BrLqEeC4NenKT57Ftw"/>
</uml:Class>
<uml:Association xmi:id="_6HP2BrLqEeC4NenKT57Ftw" name="Owns" memberEnd="_6HP2ArLqEeC4NenKT57Ftw _6HP2BbLqEeC4NenKT57Ftw"/>
</xmi:XMI>
which was created from an in-memory model. To read the model, I have the following code:
ResourceSet resourceSet = new ResourceSetImpl();
resourceSet.getResourceFactoryRegistry().getExtensionToFactoryMap().put("uml", new UMLResourceFactoryImpl());
URI uri = URI.createURI("file:/C:/projects/Myself/MyUMLProject/src/out.uml");
Resource resource = resourceSet.getResource(uri,true);
System.out.println(((Model)resource.getContents().get(0)).toString());
But the last statment gives me the following runtime error:
Exception in thread "main" java.lang.ClassCastException: org.eclipse.emf.ecore.xml.type.impl.AnyTypeImpl
at ReadFile.main(ReadFile.java:30)
But when I save the out.uml using a program, the program calls resource.getContents().add(model) first. So, why I cannot get the first model element after loading out.uml. Also, is there any API which allows me to read all instance of a specific element such as all Class' instances and Asscoaition's instances in a .uml file after it is loaded. Thanks.

Thanks for the update. I get confused about how to use that code.
what does the following statement do?
URI uri = URI.createURI("jar:file:/C:/eclipse/plugins/org.eclipse.uml2.uml.resources_2.0.0.v200606221411.jar!/");
In my previous program, it gives the file to be loaded? Where should I provide the .uml file to be loaded in this case.
Thanks.

I still have a question. So to be sure, I want to verify the following statementS.
My comment starts with // in CAPITALS.
ResourceSet resourceSet = new ResourceSetImpl();
resourceSet.getPackageRegistry().put(UMLPackage.eNS_URI, UMLPackage.eINSTANCE);
resourceSet.getResourceFactoryRegistry().getExtensionToFactoryMap().put(UMLResource.FILE_EXTENSION, UMLResource.Factory.INSTANCE);
Map uriMap = resourceSet.getURIConverter().getURIMap();
URI uri = URI.createURI("jar:file:/D:/Eclipse_Related_SW/Eclipse_Plugins/UML2_v3.2/eclipse/plugins/org.eclipse.uml2.uml.source_3.2.0.v201105231350.jar!/");
// I CHANGE THE ABOVE STATEMENT GIVING THE LOCATON OF THE BASE URI, RIGHT ?
uriMap.put(URI.createURI(UMLResource.LIBRARIES_PATHMAP), uri.appendSegment("libraries").appendSegment(""));
uriMap.put(URI.createURI(UMLResource.METAMODELS_PATHMAP), uri.appendSegment("metamodels").appendSegment(""));
uriMap.put(URI.createURI(UMLResource.PROFILES_PATHMAP), uri.appendSegment("profiles").appendSegment(""));
// NO CHANGES here, right?
/* resourceSet.getResourceFactoryRegistry().getExtensionToFactoryMap().put("uml", new UMLResourceFactoryImpl());
URI uri = URI.createURI("file:/D:/projects/Myself/MyUMLProject/src/Superstructure.uml");
*/
Resource resource = resourceSet.createResource(uri);
// SINCE I COMMENT OUT THE TWO STATEMENTS ABOVE TO LOAD THE UML FILE, HOW CAN I DO HERE?
Thanks.

Yes, you'd better find that jar's location/version on your machine.

What you had before should work nicely:
URI uri =
URI.createURI("file:/C:/projects/Myself/MyUMLProject/src/out.uml");
Resource resource = resourceSet.getResource(uri,true);
With the UML package properly registered, it should create UML instances
for you.
