Accessing the helloworld servlet on HCP from a browser

I built the helloworld servlet as a Dynamic Web project and deployed it successfully to HCP. I can successfully execute it on my local sever and it also runs within a server in eclipse. But when I try to access from a browser with the URL https://helloworld.p19421xxxxxtrial.hanatrial.ondemand.com/helloworld/HelloWorldServlet (I didn't change the URL mapping to '/' so I'm using the full name "HelloWorldServlet in the URL)

IE gives the error:

“ There’s a problem with this website’s security certificate

This might mean that someone’s trying to fool you or steal any info you send to the server. You should close this site immediately.”

From Chrome:

“Your connection is not private

Attackers might be trying to steal your information fromhelloworld.p19421xxxxxtrial.hanatrial.ondemand.com”

Should I be able to access this on HCP?
