how to find path of a software

Hi all,
I have just installed Eclipse RPM from Redhat.I simply double
clicked the rpm file , it started installing.I typed eclipse , it says
'no command found'.How to find the exact installation path of the RPM
installed.I thought it may be like , the path of Eclipse rpm is not
configured correctly.With little knowledge in Linux , I could not move
forward.
Thanks in advance.
