<title>Control Bus</title>
<para>As described in (<ulink
url="http://www.eaipatterns.com/ControlBus.html">EIP</ulink>), the idea
behind the Control Bus is that the same messaging system can be used for
monitoring and managing the components within the framework as is used for
"application-level" messaging. In Spring Integration we build upon the
adapters described above so that it's possible to send Messages as a means
of invoking exposed operations. Internally, the Control Bus uses a Spring
MBeanExporter instance to expose the various endpoints and channels. To
create an instance of the Control Bus, define a bean and provide a
reference to an MBeanServer and a domain name. <programlisting
language="xml"> &lt;jmx:control-bus mbean-exporter="mbeanExporter" operation-channel="operationChannel"/&gt;
&lt;jmx:mbean-exporter id="mbeanExporter" mbean-server="mbeanServer"/&gt;
</programlisting></para>
<para>The Control Bus has an "operationChannel" that can be accessed for
invoking operations on the MBeans that it has exported. This will also be
covered by namespace support soon to make it easier to configure
references to that channel for other producers. We will likely add some
other channels for notifications and attribute polling as well.</para>
<para>The Control Bus functionality is a work in progress. At this time,
one can perform some basic monitoring of Message Channels and/or invoke
Lifecycle operations (start/stop) on Message Endpoints. Now that the
foundation is available, however, we will be able to extend the attributes
and operations that are being exposed.</para>
