+
+
+<section name="Introduction">
+
+  <p>A <strong>Listener</strong> element defines a component that performs
+  actions when specific events occur, usually Tomcat starting or Tomcat
+  stopping.</p>
+
+  <p>Listeners may be nested inside a <a href="server.html">Server</a>, 
+  <a href="engine.html">Engine</a>, <a href="host.html">Host</a> or
+  <a href="context.html">Context</a>. Some Listeners are only intended to be
+  nested inside specific elements. These constraints are noted in the
+  documentation below.</p>
+
+</section>
+
+<section name="Attributes">
+
+  <subsection name="Common Attributes">
+
+    <p>All implementations of <strong>Listener</strong>
+    support the following attributes:</p>
+
+    <attributes>
+
+      <attribute name="className" required="true">
+        <p>Java class name of the implementation to use. This class must
+        implement the <code>org.apache.catalina.LifecycleListener</code>
+        interface.</p>
+      </attribute>
+
+    </attributes>
+
+  </subsection>
+
+  <subsection name="Standard Implementation">
+
+    <p>Unlike most Catalina components, there are several standard
+    <strong>Listener</strong> implementations available.  As a result,
+    the <code>className</code> attribute MUST be used to select the
+    implementation you wish to use.</p>
+
+    <h3>APR Lifecycle Listener (org.apache.catalina.core.AprLifecycleListener)</h3>
+
+    <p>The <strong>APR Lifecycle Listener</strong> checks for the presence of
+    the APR/native library and loads the library if it is present. For more
+    information see the <a href="../apr.html">APR/native guide</a>.</p>
+
+    <p>This listener must only be nested within <a href="server.html">Server</a>
+    elements.</p>
+
+    <p>The following additional attributes are support by the <strong>APR
+    Lifecycle Listener</strong>:</p>
+
+    <attributes>
+
+      <attribute name="SSLEngine" required="false">
+        <p>Name of the SSLEngine to use. off: Do not use SSL, on: Use SSL but no
+        specific ENGINE. The default value is <b>on</b>. This initializes the
+        native SSL engine, which must be enabled in the APR/native connector by
+        the use of the <code>SSLEnabled</code> attribute.</p>
+        <p>See the <a href="http://www.openssl.org">Official OpenSSL website</a>
+        for more details on supported SSL hardware engines and manufacturers.
+        </p>
+      </attribute>
+
+    </attributes>
+
+    <h3>Jasper Listener (org.apache.catalina.core.JasperListener)</h3>
+
+    <p>The <strong>Jasper Listener</strong> initialises the Jasper 2 JSP engine
+    before any web applications that may use it are loaded. For more
+    information on the Jasper 2 JSP engine see the
+    <a href="../jasper-howto.html">Jasper How To</a>.</p>
+
+    <p>This listener must only be nested within <a href="server.html">Server</a>
+    elements.</p>
+
+    <p>No additional attributes are support by the <strong>Jasper Listener
+    </strong>.</p>
+
+    <h3>Server Lifecycle Listener
+    (org.apache.catalina.mbeans.ServerLifecycleListener)</h3>
+
+    <p>The <strong>Server Lifecycle Listener</strong> initialises the
+    MBeanServer for the MBeans that may be used to manager Tomcat via JMX.
+    Without this listener, none of the Tomcat MBeans will be available.</p>
+
+    <p>This listener must only be nested within <a href="server.html">Server</a>
+    elements.</p>
+
+    <p>No additional attributes are support by the <strong>Server Lifecycle
+    Listener</strong>.</p>
+
+    <h3>Global Resources Lifecycle Listener
+    (org.apache.catalina.mbeans.GlobalResourcesLifecycleListener)</h3>
+
+    <p>The <strong>Global Resources Lifecycle Listener</strong> initialises the
+    Global JNDI resources defined in server.xml as part of the <a
+    href="globalresources.html">Global Resources</a> element. Without this
+    listener, none of the Global Resources will be available.</p>
+
+    <p>This listener must only be nested within <a href="server.html">Server</a>
+    elements.</p>
+
+    <p>No additional attributes are support by the <strong>Global Resources
+    Lifecycle Listener</strong>.</p>
+
+  </subsection>
+
+</section>
+
+<section name="Nested Components">
+
+  <p>No element may be nested inside a <strong>Listener</strong>.</p>
