    <p>I'm trying to use the Scala Eclipse plug-in (version 1.1.0, which appears to be the most current) with version 3.7 of Eclipse on Mac OS X 10.6.8. I've copied the "Hello, World" program from a <a href="http://www.vogella.de/articles/Scala/article.html" rel="nofollow noreferrer">tutorial website</a>. I was able to build the program successfully using the command-line <code>scalac</code> compiler. However, when I attempt to run the project as a Scala application from within Eclipse, I get an error like so:</p> <pre><code>Exception in thread "main" java.lang.NoClassDefFoundError: de/vogella/scala/first/Hello </code></pre> <p>with a bunch more stuff following. Looking in the relevant directory structure in my Eclipse workspace directory shows that the associated <code>bin</code> directory is completely empty. However, there are no errors (and indeed no messages of any sort) when I select "Build Project" from the menu. </p> <p>As far as I can tell, my Eclipse installation is otherwise functional. I can, for instance, successfully build and run Java projects.</p> <p>Any tips on where to start with troubleshooting would be greatly appreciated. Trying the suggested solutions in the most <a href="https://stackoverflow.com/questions/2535320/noclassdeffounderror-using-scala-plugin-for-eclipse">relevant-seeming existing question</a> didn't work.</p> <p><strong>EDIT</strong> to add: There isn't anything in the Error Log window except this:</p> <pre><code>System property http.nonProxyHosts has been set to local|*.local|169.254/16|*.169.254/16 by an external source. This value will be overwritten using the values from the preferences </code></pre> <p>which doesn't strike me as terribly relevant. The full text, as copied from the tutorial, of the <code>Hello.scala</code> file, is</p> <pre><code>package de.vogella.scala.first object Hello { def main (args: Array[String]) { println("Hello, world!") } } </code></pre> <p>and the package the file is a part of is called <code>de.vogella.scala.first</code>.</p>

    1. CO[Scala-Eclipse](http://www.scala-ide.org/) has been under active development. If you can upgrade, I'd recommend trying the *much* improved Scala IDE 2.0.0-beta9, or maybe even one of the nightly builds.

    2. CODo you have anything in the Error Log? Maybe the presentation compiler is crashing for some reason.

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.
