Subject Question: Hibernate SessionPerRequest with JSF navigation
Date Wed, 07 Dec 2005 04:44:10 GMT
Hi,

 

I have been pondering about this particular issue regarding the usage of
SessionPerRequest with JSF. In the SessionPerRequest pattern, a hibernate
session is open and a transaction started at the beginning of the request,
and the transaction is committed just before returning a response to the
browse.

 

I have been using this pattern for a while until a couple days ago I
realized that a request in JSF usually involves an action that navigates to
another JSF. For example a viewCustomer.jsf could have a delete customer
button, which deletes the customer and navigates to listCustomer.jsf. The
sequence of action is thus:

 

1. Begin hibernate transaction

2 .deleteCustomerAction()

3. Deletes customer from database

4. JSF navigation to listCustomer.jsf

5. Retrieve and display customer list

6. Commit hibernate transaction

 

There are two distinctly independent operations within the same Httprequest.
To be correct - the transaction should commit after step 3, and a new
transaction should begin. If I use 'redirect' in JSF navigation that is what
it would amount to. But what is the proper way to inject the commit without
redirect?

 

Regards,

Yee
