Hey man,
Well, if its already been exported and is static HTML, you can just call the html page. If you want to have it live (meaning non-static, and not in HTML) then you'll have to use eitehr the Web Component Server or the RDC Automation Server With ASP. The thing with the latter two (well, depending on how many users will be seeing the reports i guess) is that you can only have 5 users at any one time viewing the reports online. If you want more, then you need to buy more licenses from Crystal Decisions.
If you need any more info, let me know.
