Yes, it can be done, if you know the trick.  :-)

I suppose you are trying to add the News Feed widget to your personal dashboard, and chances are you have picked the widget from JTS. Right, there is a News Feed widget in every single CLM application. The trick is, you need to use the widget from the same application to serve the news feed, to avoid the HTTP 302 redirection. For example, if you want to display the feed  https://ccm.mycompany.net:9443/ccm/service/com.ibm.team.repository.common.internal.IFeedService?category=SystemLog , you need to put it in the News Feed widget from CCM. Another thing you would like to do is change the title of the widget so that you know the news feed is from which application, when you have multiple News Feed widgets in the same dashboard.
