Re: T5.2 Need Advice on JDBC and Transaction Mgmt
I've try it and it's working. Thank you very much.
Now I can use JdbcTemplate and declarative transaction on my Tapestry
Service, so I can take advantage of T 5.2 service reload feature.
This is improving productivity a lot.
Thanks...
Best regards,
Yohan Yudanara

No, as they're not instantiated by Tapestry-IoC.

Re: T5.2 Need Advice on JDBC and Transaction Mgmt

I'm implementing this approach to have live class reloading with TapestryIoC
Services Annotated with spring's @Transactional, but I have a problem:
How can I implement this approach COMPLETE, my problem is when I define for
example @Transactional(readonly=true) or
@Transactional(rollbackfor=Exception.class) , how can I implement it ?
Thanks in advance
