    <p>You'll need the dependency for the derby client</p> <pre><code>&lt;dependency&gt; &lt;groupId&gt;org.apache.derby&lt;/groupId&gt; &lt;artifactId&gt;derbyclient&lt;/artifactId&gt; &lt;version&gt;10.10.1.1&lt;/version&gt; &lt;/dependency&gt; </code></pre> <p>You will also need to make sure it is available in your container. you may wish to follow a <a href="http://spring.io/guides/tutorials/web/" rel="nofollow">spring tutorial for web MVC that covers data access</a></p> <p><strong>EDIT</strong></p> <p>I wouldn't mix dependency resolution. If you're using Maven just stick with it. It's typical to mark the dependency as <code>provided</code> as your container would have the jar deployed as part of it's setup. For example, if your container is Tomcat you would place the jar in <code>$TOMCAT_HOME/lib</code></p> <p>You should also note that Spring provides Factory Beans to <a href="http://docs.spring.io/spring/docs/3.2.4.RELEASE/spring-framework-reference/htmlsingle/#orm-hibernate" rel="nofollow">create a Session Factory</a>. The Session Factory in turn uses a Data Source to get it' Connections. By wiring your beans this way, Connection management becomes transparent and you can remove that code from your application.</p> <p>In a typical n-tier application the specifics of data access implementation are encapsulated in a Repository/DAO layer which is then accessed from a Service layer. The Service layer captures business logic and co-ordinates data inputs/retrieval.</p> <p>Your Controller should only be concerned with capturing/validating input before passing off to the Service layer, and returning output in a format expected by the client (HTML, JSON, XML, etc.)</p>

    1. COLooks like adding this solved it, but I'm not sure why, because I added the derbyclient.jar to my build path earlier, and it didn't work. Ok, I have found out why: Putting the jar on the build path is not enough, (in eclipse), I had to add the jar into Project properties/Deployment assembly/Web deployment assembly.

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.
