As a presenter, desktop sharing allows you to share your screen with other participants in the Conferences interface. Moderators are most often the presenter, but presenters can also be participants who are invited to be a presenter, such as a participant invited to be a guest speaker. Moderators can allow any participant to be a presenter at any time.
Desktop sharing is supported on all major browsers, and the Java application must be downloaded before sharing your screen as a presenter. The desktop sharing process runs as a Java application outside of your browser by launching a Java Network Launch Protocol (JNLP) file called screenshare.jnlp. As part of the download process, the Conferences interface displays a set of images that guide you through the download specific to your operating system (Mac or PC) and browser (Firefox, Chrome, Internet Explorer, Edge, or Safari).
Note: If you have trouble installing the Java file, you may need to update Java to the most recent version.
