Hello!
Why don't you just use tapestry-hibernate to let it deal with creating and
handling Hibernate sessions?
https://tapestry.apache.org/using-tapestry-with-hibernate.html
Also, I believe your code may not be incorrect, but it's not good. Unless
you want only one Hibernate session for the whole application and you never
have threads in parallel using it, your code will be fail hard. Hibernate
sessions are not thread-safe and Tapestry-IoC services are singletons by
default. Your code doesn't tell T-IoC the service is per-thread.
Also, why are you using @ServiceId? Tapestry-IoC services are usually
defined by their type, not by their id, and service ids are generally only
used when you have more than one service with the same type.
