Billingstack-ui and billingstack api

[chrismorley]

I have some naive questions arising from the fact that theres no enough documentation available. Please answer the following considering the fact that I'm new to this software and would like to trial this! I tried with 2 different grails versions - 2.1.2 (ubuntu repository) and 2.2.1 by using the latest source code, but the results are the same. I'm definitely missing something or not doing something the way the software expects me to!!

(192.168.1.11 is the machine/server IPwhere I'm running the billingstack and billingstack-ui).

1. Are there two UIs available? one billingstack-ui and the other billingstack? ie
   https://192.168.1.11:9191/billingstack and https://192.168.1.11:8181/billingstack-ui/ ?
2. How should I use these two? Because the billingstack-ui thing is not allowing me to sign-up/sign-in. Is there a default user/password available? I'm running this using "grails run-app --https" and trying to connect to https://192.168.1.11:8181/billingstack-ui/. The UI is appearing but not allowing to sign-in/sign-up
3. Is it necessary that I run billingstack (API) separately when I'm running billingstack-ui? How are they connected?
4. When I'm running billingstack using "grails run-app --https" and trying to connect to the UI as https://192.168.1.11:9191/billingstack, it prints an apache2/httpd error as below!

HTTP Status 404 - "/index.gsp" not found

Please help me.
