Overview
In order to integrate some existing web site content/functionality into your Webcenter Portal, you'll likely need to have the provided Portlet Producers Omniportlet and Web Clipping portlet installed in your Webcenter virtual machine. These make integrating with existing sites much easier and quicker than a home-grown solution, but will need to be installed if you're using the Oracle VirtualBox VM that includes Webcenter Portal.Prerequisites
First, you'll have to download the VirtualBox VM that runs Webcenter Portal from Oracle at http://www.oracle.com/technetwork/middleware/soasuite/learnmore/vmsoa-172279.html.Second, you should have already installed it, and then started it up per the instructions at the site above. In my case I have configured the "domain" wc_spaces, since I want to setup to use Webcenter Portal: Spaces locally.
