Help From BigBlueButton BBB API Expert

We have a server running BBB. Now I need to control the BBB resources from a Java application. Use case that I need to implement: 1) On the page of our java application a video must appear in a reduced format of each of the all participants of a team. 2) Each participant in a team must see all the o participants in his team. 3) Whenever a participant needs it, they can immediately start to speak with one or more participants on their team. Our Java system will: a) create a room for each team; b) control the users' login for each team; c) control sound and image control available to each user. d) whiteboard control. All of these features will be shown on a page in our JSF Java application. We need the help of a BBB API expert who will show us all the necessary commands that we need to use to implement the use case above.
