There is nothing wrong in controller or view… but something
problem in installation… what version of Instant Rails you are
using… also try to use ruby console window from Instant rails to
create apps…that adds all paths correctly…

Also start server using Instant Rails … click on “I” … “rails
application” -> “manage rails applications”…then choose your
applicaton and start server…
good luck in exploring RoR

Hi Narasimha,

Thanks for your reply.
I am using Instant rails version 1.2.3. I have tried using the “start
server with Mongrel”. There also i am facing the same problem.

I will try with ruby console now.

thanks again.

Hi,
I tried with ruby console window also. I am facing the same issue. I
hope i am doing something wrong in installation. I will check it.
Meanwhile if anybody finds the problem please guide me.
