I have the ecore file which contains the class eobjects.Now i want to read that ecore file and get all the class eobjects from that ecore file.

Do you mean you want to reload your specific xmi file with a custom suffix?
Here is an example of a method that loads an ecore file at a specific location (path) and returns your root EObject
public static EObject loadYourModel(String path) {
/*Initialzie Models*/
YourPackage.eINSTANCE.eClass();
/*register your xmi resources*/
final Resource.Factory.Registry reg = Resource.Factory.Registry.INSTANCE;
final Map<String, Object> m = reg.getExtensionToFactoryMap();
/*put all your different ecore file suffixes in the map; suffix = YourPackage.eNAME*/
m.put(YourPackage.eNAME, new XMIResourceFactoryImpl());
/*you can put all different package names here*/
/*Create a new Resource set to store the EObjects from the file*/
ResourceSet resSet = new ResourceSetImpl();
/*get the resource of your ecore file*/
Resource resource = resSet.getResource(URI.createURI(path), true);
/*Get the first element = root of your model hierachy*/
EObject root = resource.getContents().get(0);
return root;
}
