h1. Using a Spring configured full-blown transaction manager across modules in Z2
As does [[Samples-jta-plain]], so does this sample demonstrate how to use Z2 with the Atomikos transaction manager. In this case however, we choose to use the Spring framework to configure the transaction manager and enable re-use using Z2's support for modular Spring applications (see also [[How to Spring]]).
The Wiki page [[How_to_TransactionManager]] explains the general principles behind transaction handling in Z2.
This sample is stored in "z2-samples.jta-spring":http://redmine.z2-environment.net/projects/z2-samples/repository/z2-samples-jta-spring. It implements exactly the same scenario as [[Sample-spring-hibernate]] with the exception of not using the built-in JTA implementation.
h2. Prerequisites
You need to run Java DB as network server on localhost. This is explained next.
The application will create a database "z2-samples"
{{include(How to run Java db)}}
h2. Running the sample
This sample is run as explained in [[How to run a sample]]. The 5 minutes version:
<pre><code class="ruby">
mkdir install
cd install
git clone -b master http://git.z2-environment.net/z2-base.core
git clone -b master http://git.z2-environment.net/z2-samples.jta-spring
# on Linux / Mac OS:
cd z2-base.core/run/bin
./gui.sh
# on Windows:
cd z2-base.core\run\bin
gui.bat
</code></pre>
h2. Verifying
When everything is up, go to http://localhost:8080/jta-spring. You see something like this:
!jta-spring-thingies.png!
And indeed, it's the same database we use elsewhere.
h2. Now to the point...
This So, here are the details and why this sample illustrates how to use a third-party transaction manager, is interesting.
Until that part has been written (sorry) - please checkout the Atomikos implementation in this case, in a modular application as indicated in [[How_to_TransactionManager]]. This in conjunction sample. If you are familiar with Spring resulting in and have a full-blown, highly adaptable and completely modular environment, scalable in deployment and development.
slight idea about JTA, you should see the beauty of it.
