Hi Mahesh,
JAM discussions widget works on Cloud Portal with SSO.
In order to view content on this widget you should configure the widget to work with a certain data source such as a group (or company).
You must also be registered to the JAM group you are listing in the widget. The group ID, which you add to the widget, can be taken from the source code of the group's main JAM page.
Best Regards,
Boaz
