Installment 2, Spring
I've finished the second (more simple) installment of Spring with OJB if
anyone is interested.

Hey Alexandre,
I agree with you greatly. I do think that we're starting to see a lot
of Spring usage, and I like it for many of the same reasons Thomas
mentioned (Thomas, installment two has the DAO stuff you talk about
added back in).
As an FYI, take a look at the Kuali project (http://www.kuali.org/). It
is a massive undertaking being developed by a group universities,
private companies, and groups like the Open Source Lab that will result
in an ERP system including Financial Information System, Research
Administration and all that sort of thing. The primary toolset is
OJB/Spring with struts on the front.
So I think these types of tools are gaining traction.

I don't think that the reasons are "political" (the contact with Juergen
Hoeller from Spring come along well).
JDO, Hibernate, iBatis are (currently ;-)) more popular than OJB, thus
in the first instance you will find references about these frameworks.
For OJB-1.1 we intend (among other things) to make the Spring
integration easier. OJB-1.1 will be a big step forward.

The winner takes it all ;-)

Jason,
I have not read your articles for the moment but IMHO this is a very
positive initiative.
I like to work with OJB, and I also appreciate Spring a lot - they are
both great tools.
Spring aims at integration of various frameworks. It has a strong
persistence layer integration - integration is great with Hibernate,
JDO, iBatis. But you will never find any reference to OJB.
I suppose the reasons are mainly political but anyway, it's a shame.For
example, Spring is a great factor of expansion for Hibernate, as every
little sample it provides uses hibernate.
It would be a shame if OJB did not take the opportunity.
I am not yet a Spring expert, but tell me if I can help in anyway!
I'd also be interested in reading what you OJB committers (Armin,
Thomas, Jacob, Martin...) think about it!

Re: Installment 3, Spring, Text file for Armin
Posted by Armin Waibel <ar...@apache.org>.
Hi Jason,
thanks for clarification. So I think it will be the best to remove
Robert's howto in 1.x trunk and replace it with your up-to-date howto
(till OJB1.1 is released and Spring is upgraded to 1.1).
regards,
Armin

Re: Installment 3, Spring, Text file for Armin
Posted by Jason McKerr <ja...@osuosl.org>.
Hi Armin,
I read through the one that Robert did. He actually helped me quite a
bit with the three that I wrote. There are a couple of important things
there.
First, Robert's only covers configuration files. Land while it does
that well (and Robert helped me quite a bit with my config setup) it
only covers the basics. The three articles that I wrote covers
configuration, interception patterns with DAO, OJB implementations,
advanced DAO pattersn. Also Robert's only covers local datasourcing
using Springs local datasource and the localOJBConfigurer. The problem
with this is that it doesn't allow you to use server based/JNDI lookups
for your datasource strategy. More importantly, with the local
datasources and localOjbConfigurer in use, Spring users can't use OJB's
different caching strategies. Users are forced to use PerBroker. In my
articles, I cover all of the above as well as getting back to JNDI
lookups for datasourcing and eliminating the need for the
localOjbConfigurer. This in turn allows for proper use of OJB's caching
strategies. Finally, I also include three complete sample applications
that are easy to use and 2 of the 3 have embedded databases. So it's
all wrapped up. Robert actually reviewed them before I posted them.
The other issue is that Robert's writeup that you have is slightly
outdated. He is telling users to setup caching in OJB.properties
instead of repository.xml. Robert himself wrote to me and told me there
were new setups in OJB 1.0.2 and higher, so I'm surprised that he hasn't
fixed this...

Thanks again! I added your "Howto" to 1.0.x CVS branch. Will be included

Re: Installment 3, Spring, Text file for Armin
Posted by Jason McKerr <ja...@osuosl.org>.
I have finished the third installment of connecting up Spring and OJB.
This covers using non-local configurers (it eliminates the need for
ojbConfigurer) so that you can use JNDI data sources and caching
strategies other than Per Broker.
Armin, included is the text file that you asked for.
Thanks,
Jason

Armin,
I am just finishing up the third article today. As soon as I get that
done, I will write this and send along.

Thanks a lot!
I will add your articles to OJB's Link page.
Jason, if you send me a summing-up of your three articles as normal
.txt-file I will transform it to a forrest-compatible Howto and add it
to OJB-docs.

Armin

Hi Thomas,
If you guys want, feel free to take the two articles that I put up and
move them into the How-to page. I will have the third entry done in the
next few days.

First off, thanks for sharing this with us ! I use OJB with Spring for
several months now, but never got around writing a tutorial for it ;-)
Just a quick comment: the separation that Matt made concerning DAOs
and services is actually a really good idea because it separates
concerns - your actions want to execute business logic not database
accesses, and you can often want to combine several database accesses
into one business method. Also it greatly simplifies testing because
you can replace the DAOs easily (by using a different
applicationContext file) and thus test your services without having to
have a database at hand but instead against mock DAOs.
