I have just tried to make my first web application using Webratio. I have followed each and every step from this tutorial : https://docs.google.com/document/d/1XbeMz8USxPFEcLBB3jt1rXz2UEw4_ap5ZeBHL1e0VSM/pub
At first, when I have created my database, filled all the configuration details and clicked "refresh", everything was working fine - no error detected.
I have gone further with the creation proccess and at the end, when I click"Generate and run" this error appears :
java.sql.SQLNonTransientConnectionException: Insufficient data while reading from the network - expected a minimum of 6 bytes and received only 0 bytes. The connection has been terminated.

I am a beginner, so I don't have many ideas in order to solve this problem.
If you could help me with some advices, I would really appreciate it.
Thank you very much in advance!
