    <p>I should have been a bit more clear. But after several hours last night, I found the answer. First, you'll need a main object like this (or similar):</p> <pre><code>object Sandbox { def main(args: Array[String]) { val server = new Server(3000) val context = new WebAppContext() context.setServer(server) context.setContextPath("/") context.setWar("webapp") server.setHandler(context) try { server.start() server.join() } catch { case e: Exception =&gt; e.printStackTrace() System.exit(-1) } } } </code></pre> <p>Then you'll need a servlet:</p> <pre><code>class Test extends ScalatraServlet with ScalateSupport { get("/") { &lt;html&gt; &lt;body&gt; Hello World &lt;/body&gt; &lt;/html&gt; } } </code></pre> <p>You'll also need a ScalatraBootstrap class in your default package (must be named <code>ScalatraBootstrap.scala</code>:</p> <pre><code>class ScalatraBootstrap extends LifeCycle { override def init(context: ServletContext) { context.mount(new Test, "/test/*") } } </code></pre> <p>Almost done. You will need a single XML file. Create a <code>webapp/WEB-INF</code> folder and put this <code>web.xml</code> file in there.</p> <pre><code>&lt;?xml version="1.0" encoding="UTF-8"?&gt; &lt;web-app xmlns="http://java.sun.com/xml/ns/javaee" xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance" xsi:schemaLocation="http://java.sun.com/xml/ns/javaee http://java.sun.com/xml/ns/javaee/web-app_3_0.xsd" version="3.0"&gt; &lt;listener&gt; &lt;listener-class&gt;org.scalatra.servlet.ScalatraListener&lt;/listener-class&gt; &lt;/listener&gt; &lt;servlet-mapping&gt; &lt;servlet-name&gt;default&lt;/servlet-name&gt; &lt;url-pattern&gt;/img/*&lt;/url-pattern&gt; &lt;url-pattern&gt;/css/*&lt;/url-pattern&gt; &lt;url-pattern&gt;/js/*&lt;/url-pattern&gt; &lt;url-pattern&gt;/assets/*&lt;/url-pattern&gt; &lt;/servlet-mapping&gt; &lt;/web-app&gt; </code></pre> <p>Finally, you'll need the JAR files. There's a pretty long list, but there's a fairly simple way to get them. I hate Maven, but I love the dependency management. So create a test folder somewhere and download the <code>pom.xml</code> file in <a href="https://github.com/Srirangan/scalatra-maven-prototype" rel="nofollow">this</a> repo. Then go to the folder where the <code>pom.xml</code> is and run <code>mvn dependency:copy-dependencies</code>. Grab the JARs from the <code>dependencies</code> folder and you're good to go. No Maven, no SBT, no magic. Run and debug in your IDE like you always do. :)</p>

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.
