How to get the project name in eclipse?

How do I get the name of the current eclipse project? I'm in a GMF view and need the projectname when some submenu of the popup menu ist used.

This GMF class has a straightforward answer, if you have access to the ResourcesPlugin name:

IProject project = ResourcesPlugin.getWorkspace().getRoot().getProject(myBundleName);

The generic answer (from a potentially outdated code) could be like (if you have an editor opened):

IEditorPart  editorPart =
getSite().getWorkbenchWindow().getActivePage().getActiveEditor();

if(editorPart  != null)
{
    IFileEditorInput input = (IFileEditorInput)editorPart.getEditorInput() ;
    IFile file = input.getFile();
    IProject activeProject = file.getProject();
    String activeProjectName = activeProject.getName();
    //... use activeProjectName 
}

If no editor is opened:

   IViewPart [] parts =
      MyPlugin.getDefault().getWorkbench().getActiveWorkbenchWindow().getActivePage().getViews();
    IProject activeProject = null;

    for(int i=0;i<parts.length;i++)
    {
        if(parts[i] instanceof ResourceNavigator)
        {
            ResourceNavigator navigator = (ResourceNavigator)parts[i];
            StructuredSelection sel   =
              (StructuredSelection)navigator.getTreeViewer().getSelection();
            IResource resource = (IResource)sel.getFirstElement();
            activeProject = resource.getProject();
            break;
        }
    }
    String activeProjectName = activeProject .getName();
