Configuring Oracle was very simple. It has just 2 steps 1) modify oracle-ds.xml found in \docs\examples\jca folder to suit your installation and copy it to \servers\default\deploy folder 2) Copy ojdbc14.jar from \jdbc\lib folder to \servers\default\lib folder.
But I am still looking for configuring IIS. Question regarding that shouldn't be in this forum. I will post that question under Installation/Configuration forum.
