-LTTng-UST provides a _logging_ back-end for Java applications using
-either
-<a href="http://docs.oracle.com/javase/7/docs/api/java/util/logging/Logger.html" class="ext"><code>java.util.logging</code></a>
-(JUL), or
-<a href="http://logging.apache.org/log4j/1.2/" class="ext">Apache log4j 1.2</a>.
-This back-end is called the _LTTng-UST Java agent_, and is responsible
-for communications with an LTTng session daemon.
-
-<div class="tip">
-<p>
-    <span class="t">Note:</span>The latest stable version of LTTng
-    does not support Log4j 2.
-</p>
-</div>
-
-From the user's point of view, once the LTTng-UST Java agent has been
-initialized, JUL and log4j loggers may be created and used as usual.
-The agent adds its own handler to the _root logger_, so that all
-loggers may generate LTTng events with no effort.
-
-Common JUL/log4j features are supported using the `lttng` tool
-(see [Controlling tracing](#doc-controlling-tracing)):
-
-  * listing all logger names
-  * enabling/disabling events per logger name
-  * JUL/log4j log levels
-
-Here's an example using **`java.util.logging`**:
-
-~~~ java
-import java.util.logging.Logger;
-import org.lttng.ust.agent.LTTngAgent;
-
-public class Test
-{
-    private static final int answer = 42;
-
-    public static void main(String[] argv) throws Exception
-    {
-        // create a logger
-        Logger logger = Logger.getLogger("jello");
-
-        // call this as soon as possible (before logging)
-        LTTngAgent lttngAgent = LTTngAgent.getLTTngAgent();
-
-        // log at will!
-        logger.info("some info");
-        logger.warning("some warning");
-        Thread.sleep(500);
-        logger.finer("finer information; the answer is " + answer);
-        Thread.sleep(123);
-        logger.severe("error!");
-
-        // not mandatory, but cleaner
-        lttngAgent.dispose();
-    }
-}
-~~~
-
-Here's the same example, this time using **log4j**:
-
-~~~ java
-import org.apache.log4j.Logger;
-import org.apache.log4j.BasicConfigurator;
-import org.lttng.ust.agent.LTTngAgent;
-
-public class Test
-{
-    private static final int answer = 42;
-
-    public static void main(String[] argv) throws Exception
-    {
-        // create and configure a logger
-        Logger logger = Logger.getLogger(Test.class);
-        BasicConfigurator.configure();
-
-        // call this as soon as possible (before logging)
-        LTTngAgent lttngAgent = LTTngAgent.getLTTngAgent();
-
-        // log at will!
-        logger.info("some info");
-        logger.warn("some warning");
-        Thread.sleep(500);
-        logger.debug("debug information; the answer is " + answer);
-        Thread.sleep(123);
-        logger.error("error!");
-        logger.fatal("fatal error!");
-
-        // not mandatory, but cleaner
-        lttngAgent.dispose();
-    }
-}

-
-The LTTng-UST Java agent classes are packaged in a JAR file named
-`liblttng-ust-agent.jar`. It is typically located in
-`/usr/lib/lttng/java`. To compile the snippets above
-(saved as `Test.java`), do:
-
-<pre class="term">
-javac -cp /usr/lib/lttng/java/liblttng-ust-agent.jar:$LOG4JCP Test.java
-</pre>
-
-where `$LOG4JCP` is the log4j 1.2 JAR file path, if you're using log4j.
-
-You can run the resulting compiled class like this:
-
-<pre class="term">
-java -cp /usr/lib/lttng/java/liblttng-ust-agent.jar:$LOG4JCP:. Test
-</pre>

-<p>
-    <span class="t">Note:</span><a href="http://openjdk.java.net/" class="ext">OpenJDK</a> 7
-    is used for development and continuous integration, thus this
-    version is directly supported. However, the LTTng-UST Java agent has
-    also been tested with OpenJDK 6.
