I'm currently using iFrames to use Jforum from my Website. I already applied SSO to avoid users to login for the second time and be able to use jforum. However, I'm facing a problem with iFrames when I want to use the links for "My Profile", "My Posts", and "My Posts". I'm using a sidebar on a jsp page from my webapp instead of using the header links that are on the jforum website. In this case, the main problem is the number of the userid. How I can get this id from my webapp in order to bring the corresponding link for each user?
