When I see the term 'fail-over enabled', it says to me that you have multiple servers in a farm, of which 1 (and only 1) is active at a given point in time. If this is the case, then the sticky bit is not required as all requests will go to the same web server/servlet container.
I do not think the mid-tier supports clustering on the J2EE side.
