At a glance Honeycomb seems to be relying on developers having Eclipse.
We use IDEA here.

It comes with a ready to use CRUD-Application-Template to get you

Subject: Re: Open Session in View - Tapestry
I tried the hivetranse approach, but had 2 problems. 1)
hivetranse seems
to limit a hibernate session to a single transaction, and 2) its
declarative approach ultimately limits the transaction
demarcation to a
single method call, and I couldn't figure out a good way to
structure my
application such that all the work (load object, update
object, commit
transaction) occurred within the scope of a single service
method call
and still left me with a place to catch any exception and update the
view accordingly.
If someone has worked out a good pattern for using hivetranse in the
context of simple hibernate-based CRUD functionality in
Tapestry 4 with
validation, I would love to hear about it.
I also looked at what Howard is doing with Epluribus
(http://www.javaforge.com/proj/sources/sccBrowse.do?proj_id=22
0&dir=epluribus%2Ftrunk),
but that is unfinished (it does have an example of a
WebRequestServicerFilter, which is what you need to make sure the
transaction is committed/rolled-back at the end of the request, as
stated in your question).
I ended up adapting Kent Tong's SessionOwner approach from
Chapter 14 of
his indispensable book. It involves injecting the thread-specific
SessionOwner (I called it TransactionManager) into your page
and using
it to commit or rollback the transction as desired.

Hi,
I'm trying to implement Open Session in View in tapestry
application.
There is a way to create servlet filter to open and close
the db session.
(I'm using ServletRequestServicer)
My question is, how can I catch the page exception to rollback the
transaction, because
tapestry ExceptionHandling catch that exceptin and never
throw it as servlet
exception.
Sorry for my bad english :(
Rdgs,
