Re: Table with large data set
James, Does your PagingQueryResult returned by your DAO by any chance wrap a Hibernate Criteria? Later the Criteria methods setMaxResults(), setFirstResult(), addOrder() and list() are invoked from the HibernateTableModel on request? Or where do you invoke the criteria (or similar) methods?

There's only one issue which I couldn't really overcome nicely. It has to do with the sorting of the columns. I didn't want to give up the ability to easily define my columns in the HTML (using the columns attribute of the @contrib:Table component), so I put in a little hack. Basically, what you return from your DAO methods is a PagingQueryResult object which is what the HibernateTableModel uses to ask for the data for each page. But, in each PagingQueryResult you have to register what columns are sortable and how you sort them. Anyway, I'll email it to you Chris if you want it.

Re: package a hivemind service in a jar? (email service for T4)

Re: Tapernate - Rollback problem
The new version of Tapernate seems to solve this problem completely.
Thank you!

Okay. I'm seeing it now, too. Unfortunately, the Spring interceptor throws
an exception when the global transaction is marked as rollbackOnly when it's
participating. I need to figure out what the best way is to handle this.
By the way, I just got Tapernate to rollback the pojos that are changed
during a rolled back transaction. This is helping me avoid a LOT of
problems! More to follow...

Yes, I'm using spring.transaction.TransactionInterceptor on my DAO. I
am doing getTransactionUtils().setRollbackOnly() outside my DAO in the
same way as you are doing in tapernate-example.
Here is a stack trace. I will get back to you with more logging.
http://pastebin.com/734105
in AbstractPlatformTransactionManager.commit(...) :
if (!shouldCommitOnGlobalRollbackOnly()
defStatus.isGlobalRollbackOnly()) {
...
processRollback(defStatus);
throw new UnexpectedRollbackException(
Transaction has been rolled back
because it has been marked as
rollback-only);
}
Thanks

I'm trying to use setRollBackOnly() in tapernates TransactionUtils
which results in:
UnexpectedRollbackException: Transaction has been rolled back because
it has been marked as rollback-only
when the commit runs in:
org.springframework.transaction.support.AbstractPlatformTransactionManager.c
ommit(AbstractPlatformTransactionManager)
I am getting the same problem when running tapernate-example.
Does someone (James?) know a solution to my problem?

Re: New version of Tapernate...
One question,
If I retrieve an object from my DAO and change something in that
object without doing a session.update(...), the change will be
persisted (to the DB). Is this the way it should work (not having to
do a manual update) ?
public Product getProduct()
{
Product product;
product = getProductAccess().getProduct(getId());
product.setContent(this text will be written to DB);
return product;
}

Hi James,

2. Taperate now has support for three types of property persistence,
reattach-merge (used to be called entity), reattach-lock, and
reattach-update, corresponding to the three different types of reattach
strategies. You can choose which one you want to use for your situation
(reattach-update doesn't support POJO rollback, though since Hibernate
will
not give me the previous values for some reason) giving you more
fine-grained control.
3. The spring.hibernate3 module now supports an interceptor pipeline.
So, you can add as many interceptor filters as you wish, which can do
various actions (logging, auditing, etc.). The POJO rollback is
implemented
as an interceptor filter.
Tapernate will move soon. I finally got the Maven2 build to work, so now
I
just have to upload it and set up some docs for it. For those of you who
are currently using Tapernate, you don't have to upgrade, but it's
strongly
suggested.
Again, where is tapernate located? I searched last time on Howard's site
where he has tapestry-spring and other small projects but I couldn't find
your project.
I'd be interested to know more about your different reattach strategies...
Do you understand in details which one to use when?
To me lock should always be used unless you have duplicate objects, right?
And having duplicate objects is not good in hibernate, if I get it right?
I like the idea of an interceptor pipeline... Would it allow easily to
monitor performance of DAO methods?
Thanks,
Henri.
