SWT - Workspace and EPackage Registry browse

How can I implement Workspace Browse and EPackages Browse in SWT / jface? The below code browse File System not Workspace.

Button button = new Button(grpModelProperties, SWT.PUSH);
button.setText("Browse Workspace...");
button.addSelectionListener(new SelectionAdapter() {
public void widgetSelected(SelectionEvent e) {
FileDialog dialog = new FileDialog(getShell(), SWT.NULL);
String path = dialog.open();
if (path != null) {
File file = new File(path);
if (file.isFile())
displayFiles(new String[] { file.toString()});
else
displayFiles(file.list());
}
}
});

I also tried the solution presented in SWT Component for choose file only from workspace by @sambi reddy but I have the below error:

I also don't have an idea about EPackages browse.

edit: When I run the below code, no entries available although workspace has projects:

Button button2 = new Button(grpModelProperties1, SWT.PUSH);
button2.setText("Browse Workspace...");
final GridData button2Data = new GridData(SWT.RIGHT, SWT.CENTER, true, true);
button2.setLayoutData(button2Data);
button2.addSelectionListener(new SelectionAdapter() {
public void widgetSelected(SelectionEvent e2) {
    ElementTreeSelectionDialog dialog = new ElementTreeSelectionDialog(
    Display.getDefault().getActiveShell(), 
    new WorkbenchLabelProvider(), 
    new BaseWorkbenchContentProvider());
    dialog.open();
}
});

You can only access the Eclipse workspace in an Eclipse plugin, it is not available in a plain Java app because of the large amount of initialization that is required.

In your ElementTreeSelectionDialog dialog you must call setInput to tell the dialog about the elements to be displayed:

ElementTreeSelectionDialog dialog = new ElementTreeSelectionDialog(
                Display.getDefault().getActiveShell(),
                new WorkbenchLabelProvider(),
                new BaseWorkbenchContentProvider());

dialog.setInput(ResourcesPlugin.getWorkspace().getRoot());

dialog.open();

This displays the entire workspace, by changing the input to a IProject or IFolder you can restrict the display to part of the workspace.
