Oracle Database Discussions

Hi,
I was trying to run the sample hr_rails app, it did run initially but when I used the
ACTIVESCAFFOLD it is not starting, it may be bunch of things I did which is not letting me start the testing web server on port 3000.
Can anybody tell me what could be the problem ?

Thanks,
SS

Here is the error messages....
