Eclipse Plugin - How to open a wizard page in a command handler?

Question

I write a plugin for eclipse. I have a button in the toolbar menu. and I want that on pressing on it - a wizard page dialog will be opened. I wrote already a class which extends wizard and implements IWizardPage, and I wrote also all the 5 relevant pages, I only don't find any way to open this in the command handler.

Here is the pieces of my code:

The command handler:

public class AddProjectHandler extends AbstractHandler {

    @Override
    public Object execute(ExecutionEvent event) throws ExecutionException {

        return null;
    }
}

The wizard page manager:

public class NewProjectWizardManager extends Wizard implements INewWizard {


    private NewProjectWizardPage1 _page1;
    private NewProjectWizardPage2 _page2;
    private NewProjectWizardPage3 _page3;
    private NewProjectWizardPage4 _page4;
    private NewProjectWizardPage5 _page5;

    // constructor
    public NewProjectWizardManager() {
        super();
        setWindowTitle("New Project");
    }

    @Override
    public void init(IWorkbench workbench, IStructuredSelection selection) {
    }

    @Override
    public boolean performCancel() {

        return true;
    }

    @Override
    public void addPages() {
        super.addPages();
        _page1 = new NewProjectWizardPage1();
        addPage(_page1);
        _page2 = new NewProjectWizardPage2(_page1);
        addPage(_page2);
        _page3 = new NewProjectWizardPage3(_page1);
        addPage(_page3);
        _page4 = new NewProjectWizardPage4();
        addPage(_page4);
        _page5 = new NewProjectWizardPage5(_page1);
        addPage(_page5);
    }

    @Override
    public boolean canFinish() {
        IWizardContainer container = getContainer();
        if (_page5.equals(container.getCurrentPage())) {
            return true;
        } else {
            return false;
        }
    }

    @Override
    public IWizardPage getNextPage(IWizardPage page) {
        IWizardPage nextPage = super.getNextPage(page);
        IWizardContainer container = getContainer();
        if (nextPage != null) {
            if (_page2.equals(container.getCurrentPage()) && _page2.isCheckFinishChecked())
                nextPage = super.getNextPage(super.getNextPage(nextPage));
        }
        return nextPage;
    }

    @Override
    public boolean performFinish() {
}
}

The plugin.xml pieces:

<command
                categoryId="com.commands.category"
                description="Add new Project"
                id="com.commands.AddProject"
                name="Add new Project">
</command>


<handler
                class="com.handlers.AddProjectHandler"
                commandId="com.commands.AddProject">
</handler>

Do you have any idea?

Use WizardDialog to show a wizard. Something like:

public Object execute(ExecutionEvent event) throws ExecutionException
{
  Shell activeShell = HandlerUtil.getActiveShell(event);

  IWizard wizard = new NewProjectWizardManager();

  WizardDialog dialog = new WizardDialog(activeShell, wizard);

  dialog.open();

  return null;
}
