    <p>I am trying to set the java util logging config file at runtime to avoid having to set it as a VM parameter. But this just doesn't work. Whenever I am trying to reread the configuration, logging is disabled at all.</p> <p>See the following code snippet:</p> <pre class="lang-java prettyprint-override"><code>package test; import java.io.FileInputStream; import java.util.logging.Level; import java.util.logging.LogManager; import java.util.logging.Logger; public class A { private static final Logger LOGGER= Logger.getLogger(A.class.getName()); public static void main(String[] args) throws Exception { System.out.println("--- start"); LOGGER.log(Level.SEVERE, "SEVERE 1"); LOGGER.log(Level.FINEST, "FINEST 1"); LogManager.getLogManager().readConfiguration(); LOGGER.log(Level.SEVERE, "SEVERE 2"); LOGGER.log(Level.FINEST, "FINEST 2"); LogManager.getLogManager().readConfiguration(new FileInputStream("/tmp/logging.properties")); LOGGER.log(Level.SEVERE, "SEVERE 3"); LOGGER.log(Level.FINEST, "FINEST 3"); System.out.println("--- end"); } } </code></pre> <p>This is the output if I run the class without any VM argument: </p> <pre><code>--- start 09.11.2012 09:59:25 test.A main SCHWERWIEGEND: SEVERE 1 09.11.2012 09:59:25 test.A main SCHWERWIEGEND: SEVERE 2 --- end </code></pre> <p>As you can see, only the SEVERE levels are logged, as this is the default of the JREs logging.properties. Calling <code>LogManager#readConfiguration()</code> doesn't change anything. But when trying to read the configuration from my logging.properties, absolutely nothing is logged. There is no difference in calling <code>LogManager#readConfiguration(InputStream)</code> or setting the <code>java.util.logging.config.file</code> property and calling <code>LogManager#readConfiguration()</code>.</p> <p>Now see the next output, when I run the same code with the VM property <code>-Djava.util.logging.config.file=/tmp/logging.properties</code> : </p> <pre><code>--- start 2012-11-09 10:03:44.0838 SEVERE [test.A#main()] - SEVERE 1 2012-11-09 10:03:44.0843 FINEST [test.A#main()] - FINEST 1 --- end </code></pre> <p>As you can see, both the SEVERE and the FINEST levels are logged and they are logged in a different format. Both is specified in my custom <code>logging.properties</code>. But logging stops here after calling <code>LogManager#readConfiguration()</code>! This is different from the example above and I don't understand it. Also, just as in the example above, calling <code>LogManager#readConfiguration(InputStream)</code> doesn't work.</p> <p>So what is the problem? According to the <a href="http://docs.oracle.com/javase/6/docs/api/java/util/logging/LogManager.html" rel="noreferrer">javadoc</a> setting the java.util.logging.config.file property at runtime should work. Also both readConfiguration() methods should work as I expect. So what is the problem?</p>

    2. CONo, it doesn't help. Maybe I misunderstand your suggestion, but that question and its answer talk about configuring the logger fully programmatically. I want to use the logging.properties file, but read it at runtime (since I don't want to set a VM parameter at the commandline). Also, what is confusing me, is that the `readConfiguration()` methods don't seem to do what they are meant to do.

    3. COI tested it, it works for me. `readConfiguration()` reads configuration and after this, the new logger config is used. JDK 1.6.0_27.

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.
