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 again! I added your "Howto" to 1.0.x CVS branch. Will be included
in 1.0.4.
http://cvs.apache.org/viewcvs.cgi/db-ojb/src/doc/forrest/src/documentation/content/xdocs/docu/howtos/howto-use-spring.xml?rev=1.1.2.1&only_with_tag=OJB_1_0_RELEASE&view=markup
Ops, in OJB 1.1 trunk I found a Spring Howto by Robert S. Sfeir
http://cvs.apache.org/viewcvs.cgi/db-ojb/src/doc/forrest/src/documentation/content/xdocs/docu/howtos/howto-use-ojb-with-springframework.xml?rev=1.3&view=markup
This stuff was checked in 7 month ago. Is it up to date? What's the
difference compared with your articles?
regards,
Armin
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.

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.
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.
regards,
Armin

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.

Included are three articles that are in-depth How-to's for using Spring
Framework's declarative transaction engine with OJB's Persistence Broker
implementation. For each article, I have included a complete sample
application with an embedded database that you can run. They are simple to
setup and require minimal configuration.
The first article covers a basic configuration and setup for integrating Spring
with OJB. It covers:
-Connecting to the database using Spring's local datasources
(LocalOjbConfigurer)
-Register the appropriate transactionManager for use with OJB
(PersistenceBrokerTransactionManager)
-Creating beans and interfaces for use with the database
-Having Spring handle transactions for the beans in declarative fashion
The article link is: http://staff.osuosl.org/~mckerrj/?p=3
The second article covers more advanced Spring usage, separating out the
database implementation code from your Data Access Objects. This is an
important abstraction layer for controlling data access ubiquitously.
The article is http://staff.osuosl.org/~mckerrj/?p=4
The Third article covers using OJB's datasourcing and caching strategies. The
first two articles require local datasources and Per Broker caching because of
the way that the OjbConfigurer works. Now that we've completed basics of
integrating OJB in Spring, this last entry shows how to use JNDI datasourcing
with OJB and Spring, which in turn allows users to get back to other OJB
caching strategies.
