z2-Environment

h1. A plain Hibernate on Z2 sample

Note that Hibernate is used in other samples as well, such as [[Sample-jta-plain]], [[Sample-jta-spring]], and others. This sample shows the minimal things to do to use Hibernate as an implementation of the Java Persistence API ("JPA":http://de.wikipedia.org/wiki/Java_Persistence_API). 

This sample is stored in the repository "z2-samples.hibernate.basic":http://redmine.z2-environment.net/projects/z2-samples/repository/z2-samples-hibernate-basic. 

h2. Prerequisites

You need the *z_tx_tests* database on a local MySQL database system. Start the MySQL client as the root user and run:

<pre><code class="SQL">

create database z_tx_tests;

grant all on z_tx_tests.* to tx@localhost identified by 'tx';

</code></pre>

h2. Run it

Like all samples, also this sample can be run as in [[How to run a sample]]. If you have the database, the fastest way to verify whether it runs is:

<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.hibernate-basic

# 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. Details

The assumption of this example is that of a re-use domain module that implements a "Thingy Repository" and is used from a web application that is in another module.

If everything would happen inside one module, the structure could be kept even simpler.
