Help needed in starting Coldfusion

You don't say if you've successfully installed ColdFusion or not, but if you have, log into the ColdFusion Administrator ( http://localhost/CFIDE/administrator) and find the link for the Getting Started Experience. This has a lot of good samples to get you started.

Can u let me know on which OS the cold fusion is installed? According to that in case of windows u can restart it using
command prompt
1) go to the path cf_root/bin and there type a command jrun.exe -start cfusion
Note :- cfusion is the service name that has to be started.
2) In case to start the JRun
go to path cf_root/bin and jrun.exe -start admin

Check by netstat the ports assigned to the coldfusion server must be in listen state.

I recommend the book "Adobe ColdFusion 8 Web Application Construction Kit, Volume 1: Getting Started (Web Application Construction Kit)" by Ben Forta and others.
