How to create context sensitive help and call the role based help from my Java Project?

Hello All,

I am new to Robo Help. I have created a Robo help for my Java Web Applicaion. My application is role base i.e some user's will not see some of the pages of the application. So I want to hide those pages in Robo help as well. I tried creating multiple TOC for different Roles.

My Question is

1. How to call robo Help from my application?(I will be calling using java script. If it is with RoboHelp_CSH.js where can I get that and How to implement it in my project)
2. How to implement role based help?

Thanks,

Siva.
