Blackberry push sdk error

Question

I have installed Blackberry push sdk after referring the BPSS installation guide. All the necessary software has been installed. Now I can access Tomcat home page via the https URL but I cant open any sample URL in push sdk it gives an error saying that

HTTP Status 404 - /sample-push-initiator

type Status report

message /sample-push-initiator

description The requested resource (/sample-push-initiator) is not available.

Apache Tomcat/7.0.26

Why is this ?? What I have missed here ?? Please tell me I'm stuck here. Thanks!
