    <p>You'll need to define a pom.xml for the project which declares the dependencies.<br> When you build with maven the dependencies will be downloaded from the remote repositories and stored in you local repository ${userhome}/.m2/repository.<br> The maven build will also bindle the dependencies in your war file. </p> <p>The easiest way to get started is by creating a project structure using an archetype. </p> <p>There are 2 archetypes that I've tried for gae so far: </p> <ol> <li>gae-archetype-gwt, which is built adjacent to the gae-maven-plugin, see this <a href="http://blog.gunawan.me/2010/09/maven-gae-integration-step-by-step.html" rel="nofollow">article</a>.</li> <li>gae-eclipse-maven-archetype, see this <a href="http://hamandeggs.wordpress.com/2010/01/26/how-to-gae-eclipse-maven/" rel="nofollow">article</a> and also note the link at the top of the article for the helios update.</li> </ol> <p>As the name suggests gae-eclipse-maven-archetype has better support for eclipse, I have been finding that the configurations for maven and eclipse have been clashing with each other, which gae-eclipse-maven-archetype goes a long way to alleviate. </p> <p>If your current project is not using the <a href="http://maven.apache.org/guides/introduction/introduction-to-the-standard-directory-layout.html" rel="nofollow">maven directory structure</a>, then you are going to have an uphill battle. Maven projects are easier to configure if you try to fit in with the defaults which are largely sensible options, rather than going against the grain and having to override all of the default configuration options.</p>

    1. COJust a note on the integration. The App Engine dependencies being currently available at Maven central repositories brings in another problem. In the SDK the datanucleus-appengine version is 1.0.8.final whereas in the repository it's plain 1.0.8. That'll sometimes end you up with the same JAR twice in the WEB-INF/lib. I haven't yet figured out a way to solve this, but once I find it out it'll become part of the archetype. Regards, the author of the gae-eclipse-maven-archetype.

A row detail

Detail views are divided into sections. All the information in the data section comes from columns in the selected row. The other sections display data from other, related rows.

Related data can be related in a to-one or a to-many fashion. Captions of data related in a to-many fashion link to a list view showing a filtered view of the table.

Try moving around until you find a non-empty to-many entry and click on the label to get to one. You can move back to the root by clicking on the database name in the header.
