    <p>Loggers only log the message, i.e. they create the log records (or logging requests). They do not publish the messages to the destinations, which is taken care of by the Handlers. Setting the level of a logger, only causes it to <em>create</em> log records matching that level or higher.</p> <p>You might be using a <a href="http://docs.oracle.com/javase/6/docs/api/java/util/logging/ConsoleHandler.html" rel="noreferrer"><code>ConsoleHandler</code></a> (I couldn't infer where your output is System.err or a file, but I would assume that it is the former), which defaults to publishing log records of the level <code>Level.INFO</code>. You will have to configure this handler, to publish log records of level <code>Level.FINER</code> and higher, for the desired outcome.</p> <p>I would recommend reading the <a href="http://docs.oracle.com/javase/6/docs/technotes/guides/logging/overview.html" rel="noreferrer">Java Logging Overview</a> guide, in order to understand the underlying design. The guide covers the difference between the concept of a Logger and a Handler.</p> <p><strong>Editing the handler level</strong></p> <p><strong><em>1. Using the Configuration file</em></strong></p> <p>The java.util.logging properties file (by default, this is the <code>logging.properties</code> file in <code>JRE_HOME/lib</code>) can be modified to change the default level of the ConsoleHandler:</p> <pre><code>java.util.logging.ConsoleHandler.level = FINER </code></pre> <p><strong><em>2. Creating handlers at runtime</em></strong></p> <p>This is not recommended, for it would result in overriding the global configuration. Using this throughout your code base will result in a possibly unmanageable logger configuration.</p> <pre><code>Handler consoleHandler = new ConsoleHandler(); consoleHandler.setLevel(Level.FINER); Logger.getAnonymousLogger().addHandler(consoleHandler); </code></pre>

    1. COThanks. That did the trick. I realize now why I was initially so confused. I had previously worked with logging levels, but my implementation at that time simply dropped every logged message into a list that was displayed with no regard to the `Handler`.

    2. COYou're welcome. And yeah, the design does get to you, if one has been writing loggers that simply dumped strings into a file, console etc.

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.
