    <p>When the servers starts up, I see all the correct log4j configuration in the console. However, I don't see any log messages from spring framework.</p> <p>Also, I added some code that outputs defined loggers, and I see that my spring logger is defined. Why don't I see any log messages from spring?</p> <pre><code>Enumeration loggers = Logger.getDefaultHierarchy().getCurrentLoggers(); while( loggers.hasMoreElements()){ Logger logger = (Logger) loggers.nextElement(); System.out.println(logger.getName()+","+logger.getLevel()); } SystemOut O org.springframework,DEBUG </code></pre> <p>My web.xml is (log4j/spring section):</p> <pre><code>&lt;context-param&gt; &lt;param-name&gt;log4jConfigLocation&lt;/param-name&gt; &lt;param-value&gt;/WEB-INF/resource/log4j.xml&lt;/param-value&gt; &lt;/context-param&gt; &lt;listener&gt; &lt;listener-class&gt;org.springframework.web.util.Log4jConfigListener&lt;/listener-class&gt; &lt;/listener&gt; </code></pre> <p>My log4j.xml is:</p> <pre><code>&lt;?xml version="1.0" encoding="UTF-8" ?&gt; &lt;!DOCTYPE log4j:configuration SYSTEM "log4j.dtd"&gt; &lt;log4j:configuration debug="true" xmlns:log4j="http://jakarta.apache.org/log4j/"&gt; &lt;appender name="ConsoleAppender" class="org.apache.log4j.ConsoleAppender"&gt; &lt;layout class="org.apache.log4j.PatternLayout"&gt; &lt;param name="conversionPattern" value="%5p %d %C{1} - %m%n" /&gt; &lt;/layout&gt; &lt;/appender&gt; &lt;!-- Loggers to filter out various class paths --&gt; &lt;logger name="org.springframework" additivity="false"&gt; &lt;level value="debug"/&gt; &lt;appender-ref ref="ConsoleAppender" /&gt; &lt;/logger&gt; &lt;/log4j:configuration&gt; </code></pre> <p>Here's what I see in the console:</p> <pre><code>SystemOut O log4j: System property is :null SystemOut O log4j: Standard DocumentBuilderFactory search succeded.

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.

If you are curious you may find further information in the browser console, which is accessible through the devtools (F12).
