| <div class="paragraph"> |
| <p>VS is distributed as a Zip file. This can be |
| downloaded from <a href="http://www.eclipse.org/virgo/download/">here</a>.</p> |
| </div> |
| <div class="paragraph"> |
| <p>Once the Zip file is unpacked you will find several things inside, |
| including a copy of this documentation in the <code>docs</code> folder. The layout |
| is shown below.</p> |
| </div> |
| <div class="imageblock"> |
| <div class="content"> |
| <img src="images/snapsZipFile.png" alt="snapsZipFile"> |
| </div> |
| </div> |
| <div class="paragraph"> |
| <p>Take the bundles and plan in the <code>dist</code> folder and place them in either |
| the <code>/repository/usr</code> or <code>/repository/ext</code> folder of your Virgo install. |
| Later you need the bundles in the <code>sample</code> folder. If you wish to view |
| the source for VS or its sample, then these are |
| in the <code>src</code> folder.</p> |
| </div> |
| <div class="paragraph"> |
| <p>In order to start the Snaps system as a part of your |
| Virgo Server for Apache Tomcat, the Snaps plan needs to be referenced from the |
| <code>initialArtifacts</code> property. This is located in the config file at |
| <code>${SERVER_HOME}/config/org.eclipse.virgo.kernel.userregion.properties</code>. |
| The property should be extended like this.</p> |
| </div> |
| <div class="literalblock"> |
| <div class="content"> |
| <pre>initialArtifacts=repository:plan/org.eclipse.virgo.kernel.userregion.springdm, |
| repository:plan/org.eclipse.virgo.web.tomcat, |
| repository:plan/org.eclipse.virgo.snaps</pre> |
| </div> |
| </div> |
| <div class="paragraph"> |
| <p>Now you are ready to check that Snaps is working.</p> |
| </div> |
| </div> |
| <div class="sect2"> |
| <h3 id="installation-post">Verifying it’s working</h3> |
| <div class="paragraph"> |
| <p>The sample application in the Zip file demonstrates all of the features |
| of Snaps. You will cover this application in detail later, but for now |
| install it to verify that you have a working Snaps install. Start the |
| server up and check the output it produces contains the following:</p> |
| </div> |
| <div class="literalblock"> |
| <div class="content"> |
| <pre><DE0004I> Starting plan 'org.eclipse.virgo.snaps' version '3.0.0'. |
| <DE0004I> Starting bundle 'org.eclipse.virgo.snaps.api' version '[version]'. |
| <DE0005I> Started bundle 'org.eclipse.virgo.snaps.api' version '[version]'. |
| <DE0004I> Starting bundle 'org.eclipse.virgo.snaps.core' version '[version]'. |
| <DE0005I> Started bundle 'org.eclipse.virgo.snaps.core' version '[version]'. |
| <DE0005I> Started plan 'org.eclipse.virgo.snaps' version '3.0.0'.</pre> |
| </div> |
| </div> |
| <div class="paragraph"> |
| <p>Open up the Virgo Admin Console by navigating to |
| <code><a href="http://localhost:8080/admin" class="bare">http://localhost:8080/admin</a></code> and then go to the artifacts tab to deploy |
| some new bundles. The first bundle to deploy is located at |
| <code>/sample/org.eclipse.virgo.snaps.sample.animal-[version].jar</code>, |
| select it in the browser and upload. In the terminal window you started |
| the Virgo Server for Apache Tomcat in you should see the usual messages about the |
| bundle starting and this message:</p> |
| </div> |
| <div class="literalblock"> |
| <div class="content"> |
| <pre><SN0000I> Host created for path '/animal-menu-bar'</pre> |
| </div> |
| </div> |
| <div class="paragraph"> |
| <p>This shows that the host has been registered and is ready for Snaps to |
| attach to it. To view the application take your browser to |
| <code><a href="http://localhost:8080/animal-menu-bar/" class="bare">http://localhost:8080/animal-menu-bar/</a></code>. You should be presented with a |
| green looking page that has a menu bar with two links on it. One will |
| take you to the page you are currently on while the other goes back to |
| the admin page.</p> |
| </div> |
| <div class="paragraph"> |
| <p>This is all very nice, but it’s time to deploy another snap that will |
| dynamicaly add some extra content to the app. The next bundle to deploy |
| is located at |
| <code>/sample/org.eclipse.virgo.snaps.sample.dog-[version].jar</code>. |
| Deploy it the same way as the last one using the admin console and check |
| the messages to verify it has been bound to the host:</p> |
| </div> |
| <div class="literalblock"> |
| <div class="content"> |
| <pre><SN0010I> Snap bound to path '/animal-menu-bar/dog'</pre> |
| </div> |
| </div> |
| <div class="paragraph"> |
| <p>In your browser, go back to the application and refresh the page and a |
| new menu item should now be present. If you click it a new page will |
| load with content from the newly installed snap. In this case a picture |
| of a dog.</p> |
| </div> |
| <div class="imageblock"> |
| <div class="content"> |
| <img src="images/sampleDog.png" alt="sampleDog"> |
| </div> |
| </div> |
| <div class="paragraph"> |
| <p>You have now verified that your install is working and can continue on |
| to learn how Snaps works and how you can use it to break up your web |
| applications.</p> |
