The match was the 85th FAI Cup Final, and the second to be held at the RDS since Lansdowne Road shut for redevelopment.
The winning team qualified for the 2009–10 UEFA Europa League, the first time this competition will run.
As was the case for much of the season, Bohemians' manager Pat Fenlon had to adjust his defence as Jason McGuinness missed the match through suspension.
In McGuinness's absence, Ken Oman partnered Liam Burns in the middle of the defence.
Anto Murphy left Fenlon having to choose Jason Byrne, Mindaugas Kalonas or John Paul Kelly as his replacement.
