APSRTC Online Booking - comments

Finally APSRTC started Online Ticket Booking.

http://www.apsrtc.in/APSRTCOnline

Application's response is pretty fast (may be because there is no traffic?)
My observations:
* There is no SSL during login, hope their payment gateway is secure.
* Its a struts based Java app running on IBM Websphere
* Left the default apps running: http://www.apsrtc.in/hitcount
* Developers dont know the difference between HTML comments and JSP comments. View source of the home page shows lot of commented HTML code.
* Uses struts validator framework for validations on serverside and client side. Smart way to avoid load on the server and do all validations on client first.
* While searching for From and To location, just enter % and you get all locations.
