HP OM and HPOO integration

Hi Experts,

    I am setting up a demo for my customer to demonstrate run book automation. The customer is running OVO8 with JRE 1.5 but the current OO supports JRE 1.6.x.  


Any suggestions on how i can get the demo up quickly.


Can i go to older version of OO?

Can i use older versions JRSFlowInvoke to invoke OO process?


Appreciate a quick response.


Kind Regards
