Newbie WebDynpro question

I created a simple hello world WebDynpro application from tutorial.

(https://www.sdn.sap.com/irj/servlet/prt/portal/prtroot/com.sap.km.cm.docs/library/webas/a-c/creating your First Web Dynpro Application.pdf)

I can deploy and test this webDynpro app from NWDS. It runs fine. It creates a EAR file.

But I want to create a PAR file instead and use it to build a IView. I cannot get project to export par file.

How to generate a PAR file from WebDynpro application?

[From discussion in the following thread it seems like should be possible to create PAR file

Thanks for any pointers as to how exactly to get PAR file from WebDynPro application.
