I have to test Remedy HelpDesk Client Server and Web Applications(AR System 5.x). Can anyone suggest me, which tool can be used to automate the testing?

I would like to know, whether Mercury Interactive provides an AddIns for Remedy application. I tried using WinRunner with VB, ActiveX and Web AddIns. Most of the objects are not recognized. Does QTP supports it?

Please give me a suggestion ASAP.
