Integerate with Web Access application

[MaryArt]

I am new at Crystal Reports and am exploring ways we can use it. We are using CR Professional v.8.5.

We would like to integrate a Crystal Report into an Adobe Workflow web access application. To do this, do we need to buy Crystal Reports Server and set up an additional server? Or do we have what we need with CR Professional v.8.5?

Any and all information would be greatly appreciated.

Thanks in advance.
