    <p>Jboss already comes with log4j. When developing your EJB you need to:</p> <ol> <li>import the Logger class: <code>import org.apache.log4j.Logger;</code> </li> <li>If the import does not resolve, add this jar to the path: %JBOSS_HOME%\modules\org\apache\log4j\main\log4j-1.2.16.jar</li> <li>create a field with the logger: <code>private static Logger logger = Logger.getLogger(YourEJBClass.class);</code></li> <li>use the logger in any method: <code>logger.info("my log");</code></li> </ol> <p>JBoss already comes with a configuration file under <code>%JBOSS_FOLDER%/standalone/configuration/standalone.xml</code>. By default, your logger will output to server.log and console, but you can add some appender to output your app logs to another file. </p> <p>Here is an example, edit that file and add the following snippets (following the definition of the file):</p> <ul> <li>this one is to add an appender to the file myappfile.log inside the logs folder (add this right after the already defined under name="FILE"):</li> </ul> <blockquote> <pre><code>&lt;periodic-rotating-file-handler name="FILETWO"&gt; &lt;formatter&gt; &lt;pattern-formatter pattern="%d{HH:mm:ss,SSS} %-5p [%c] (%t) %s%E%n"/&gt; &lt;/formatter&gt; &lt;file relative-to="jboss.server.log.dir" path="myappfile.log"/&gt; &lt;suffix value=".yyyy-MM-dd"/&gt; &lt;append value="true"/&gt; &lt;/periodic-rotating-file-handler&gt; </code></pre> </blockquote> <ul> <li>add this snippet tells log4j to send all logs from "com.mypackage" category to the previously created appender (copy this right after other defined logger in the file, but before the root-logger):</li> </ul> <blockquote> <pre><code>&lt;logger category="com.mypackage"&gt; &lt;level name="DEBUG"/&gt; &lt;handlers&gt; &lt;handler name="CONSOLE"/&gt; &lt;handler name="FILETWO"/&gt; &lt;/handlers&gt; &lt;/logger&gt; </code></pre> </blockquote> <p>Restart the server and you should see the new myappfile.log in the folder. Make sure your app logs something, for example, adding logger.info("my servlet info log") in some servlet and call it from the browser. You'll also see this log in the console</p> <p>If you need further customization, have a look at log4j help.</p>

    1. COTy rafael for responding. I'm using jboss as 7.1.1 and in the jboss folder there is no folder "config" with "jboss-log4j.xml", if i want to use "import org.apache.log4j.*" i should add to the classpath its relative jar hence it would be in conflict with the supposed already present log4j, can you please be kind and be more clear in your explanation (which i appreaciate a lot since is the more comprehenisble since now of all of those i've seen). Thanks

    2. CONo problem. For the import, if you are using eclipse, just add the runtime environment to the classpath (project properties -> Java Build Path -> Libraries -> Add Library -> Server Runtime -> your_server). If you don't have the server configured, just add the log4j.jar to the classpath (present in the %JBOSS_PATH%/common/lib/.

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.
