| <p><strong>Note:</strong> |
| These instructions are for the 0.2-incubating release of Aries. |
| In the 0.2-incubating release the sample was changed to use an in-memory |
| database to avoid dependency on an explicit version of Derby. If you would |
| prefer to use a database on disk check the instructions for the |
| 0.1-incubating release. You will also need to modify datasource.xml (under |
| blog-datasource) as indicated in the comments and then rebuild the sample.</p> |

| <p>Download and unzip the source zip for the <a href="aries:downloads.html">latest release</a> |

| dependencies.</p> |

| <h3 id="running_the_blog_sample_1">Running the Blog sample</h3> |
| <p>Download the JDBC based Blog sample application (.eba file) from the <a href="aries:downloads.html">latest release</a> |
| . Change directory to the blog-assembly target directory:</p> |
| <div class="codehilite"><pre><span class="n">cd</span> <span class="n">samples</span><span class="o">-</span><span class="mf">0.2</span><span class="o">-</span><span class="n">incubating</span><span class="sr">/blog-sample/</span><span class="n">blog</span><span class="o">-</span><span class="n">assembly</span><span class="o">/</span><span class="n">target</span> |
| </pre></div> |
| |
| |
| <p>now start Aries in an OSGi framework (we're using Eclipse Equinox in this |
| case)</p> |
| <div class="codehilite"><pre><span class="n">java</span> <span class="o">-</span><span class="n">jar</span> <span class="n">osgi</span><span class="o">-</span><span class="mf">3.5.0</span><span class="o">.</span><span class="n">v20090520</span><span class="o">.</span><span class="n">jar</span> <span class="o">-</span><span class="n">console</span> |
| </pre></div> |
| |
| |
| <p>The OSGi console should start up, the 'ss' command should show all of the |
| Blog bundles in state 'ACTIVE'.</p> |
| <p>Now start the blog application (.eba file) you downloaded earlier, by |
| copying it into the load directory which was created when Aries started.</p> |
| <p>Point your browser to <a href="http://localhost:8080/org.apache.aries.samples.blog.web/">http://localhost:8080/org.apache.aries.samples.blog.web/</a></p> |
| <p>If you subsequently delete the .eba from the load directory the application |
| will be uninstalled.</p> |
| <p><a name="BlogSample-RunningthesampleusingaJPApersistencelayer"></a></p> |
| <h3 id="running_the_sample_using_a_jpa_persistence_layer">Running the sample using a JPA persistence layer</h3> |
| <p>The first blog sample application was written to use a JDBC persistence |
| layer. There is a second application implemented to demonstrate the JPA |
| capability</p> |
| <p>To run the blog sample which uses the JPA persistence layer, start the OSGi |
| framework, remove any previous copies of the blog sample from the |
| target/load directory, then copy the Blog sample JPA .eba file into the |
| load directory.</p> |
| <p>Finally, after typing 'refresh' at the OSGi console, point your browser at <a href="http://localhost:8080/org.apache.aries.samples.blog.web/">http://localhost:8080/org.apache.aries.samples.blog.web/</a> |
| . You should see something that looks precisely the same as the blog sample |
| running with the JDBC persistence layer, but this time running using the |
| JPA persistence layer.</p> |
