    <p>I'm using java util logging for logging in a small Java EE application. To add an additional FileHandler (for example for errors/warnings), I created a LoggerFactory that creates the actual logger and that statically add a filehandler to the "main" logger.</p> <pre><code>package de.il.myapp.logging; public class LoggerFactory { private static final java.util.logging.Logger MAIN_LOGGER = java.util.logging.Logger.getLogger("de.il.myapp"); static { try { final java.util.logging.FileHandler fh = new java.util.logging.FileHandler("error.log", 1024*1024, 5, true); fh.setLevel(Level.WARNING); final java.util.logging.Formatter formatterTxt = new java.util.logging.SimpleFormatter(); fh.setFormatter(formatterTxt); MAIN_LOGGER.addHandler(fh); } catch (final IOException e) { //... } } } public static final Logger getLogger(final Class&lt;?&gt; clazz){ return java.util.logging.Logger.getLogger(clazz); } } </code></pre> <p>Everything works fine, except, when I stop the application, the lck file are still there. On a start, a new lck is created. So after some restarts the directory looks like this.</p> <pre><code> error.log.0 error.log.0.1 error.log.0.1.lck error.log.0.2 error.log.0.2.lck error.log.0.3 error.log.0.3.lck error.log.0.lck </code></pre> <p>The question is: How can I avoid this? Do I have to close the filehandler at the end? But where? Since this is a Java EE application I don't you an exit point, do I? And why do I get ..log.0.X for the logfiles, not just ..log.0? </p> <p>Thanks, Ingo</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.
