The logback demo can be packaged as a <em>war</em> file and + deployed to an application server. We strongly recommand the use of + <a href="http://maven.apache.org/">Maven 2</a> to do this + task, since all it will take to compile, package and run a server with the demo is + a single command. +</p> + +<p> + Using Maven, let's run the demo for the first time.

The <code>RollingFileAppender</code> sends logging events + to a file called <em>logFile.log</em> and will rollover + the active file every minute. The old file will be renamed and compressed using the <em>zip</em> + format. The <code>ConsoleAppender</code> will output the logging requests to the console, + and shorten the logger names to gain some space in the console window, without making the + names unreadable. +</p> + +<p> + Let's now visit the <em>ViewStatii</em> page, via the navigation menu on the left hand + of the screen. This page contains the content of the <code>Status</code> objects that were + created until now. <code>Status</code> objects are a part of logback's powerful internal + reporting framework. They allow you to see what is going on in logback, and check + that a configuration file has been parsed correctly, or that a rollover has occured as + expected. +</p> + +<p>image statii page</p> + +<p> +Visiting the <em>View logs</em> page does not impress much at the moment. Let us uncomment +the two parts of the config file that are below the <em>Part I: Cyclic buffer</em> comment. +Now reload the web-app by exiting the previous command with <em>CTRL-C</em> and issuing it +again: <em>mvn jetty:run</em>. +</p> + +<p> +Now, the <em>View logs</em> page looks prettier. Thanks to the <code>CyclicBufferAppender</code>, +this page can fetch the last events and present them through a servlet. +</p> + + + + + + + + + + + + + + + + + + + + + + + + </body> +</document> \ No newline at end of file Modified: logback/trunk/logback-site/src/site/xdocTemplates/manual/joran.xml ============================================================================== --- logback/trunk/logback-site/src/site/xdocTemplates/manual/joran.xml (original) +++ logback/trunk/logback-site/src/site/xdocTemplates/manual/joran.xml Fri Dec 22 20:39:40 2006 @@ -513,7 +513,7 @@ <ul> <p>Logback tries to find a file called <em>logback.xml</em> within the classpath.</p> <p>If no such file is found, it checks for another file called <em>logback-test.xml</em>.</p> - <p>In case no files are found, logback configures itself automatically thanks to the + <p>In case none of these files are found, logback configures itself automatically thanks to the <a href="../xref/ch/qos/logback/classic/BasicConfigurator.html"><code>BasicConfigurator</code> </a> class.</p> </ul> @@ -1215,6 +1215,64 @@ and only in that file. </p> +<h4>Variable substitution</h4> + +<p> +All option <em>values</em> admit variable substitution.
