Hello;
= = = = = = = = = = =
It would be useful to have a mention and link from;
.../doc30/caching-and-fresh-data.html
to here;
.../doc30/configuring-caching-behavior.html
= = = = = = = = = = =
On the page;
.../doc30/configuring-caching-behavior.html
I am not sure what mark-up system it uses so I have left this in LaTeX for now;
Ari - hope you can transcribe this OK. This appears to work fine, but feel
free to edit it if I have made any mistakes;
\subsection{Configuration of JMS Change Notification in a Jetty 7 Deployment
with ActiveMQ}
It is assumed that the Jetty deployment has been configured to "look in" {\tt
lib/ext}. Also assumed is that the Jetty deployment is configured to support
JNDI. Both of these configurations can be achieved by editing the following
line in the {\tt start.ini} to look something like this;
\framebox{OPTIONS=Server,jmx,resources,websocket,ext,plus}
In this example, the messaging middleware server
\href{http://activemq.apache.org}{ActiveMQ} is employed. The use of ActiveMQ
assumes that the necessary client ActiveMQ driver jar files from the ActiveMQ
distribution have been installed into the {\tt lib/ext} directory in the Jetty
deployment.
In this example, the ficticious Cayenne ``Data Domain Name'' is called ``foo''.
In the Cayenne modeller, the ``Remote Change Notifications'' is checked and
the ``Connection Factory Name'' is set to;
\framebox{jms/footopicconnectionfactory}
The following would appear in the {\tt jetty.xml} file;
\vspace{.2in}
\hrule
\begin{verbatim}<New class="org.eclipse.jetty.plus.jndi.Resource">
<Arg></Arg>
<Arg>jms/footopicconnectionfactory</Arg>
<Arg>
<New class="org.apache.activemq.ActiveMQConnectionFactory">
<Arg>tcp://msg01.foo.co.nz:61616</Arg>
</New>
</Arg>
</New>
<New class="org.eclipse.jetty.plus.jndi.Resource">
<Arg>org_apache_cayenne_access_DataRowStore_foo</Arg>
<Arg>
<New class="org.apache.activemq.command.ActiveMQTopic">
<Arg>foochangenotificationtopic</Arg>
</New>
</Arg>
</New>
\end{verbatim}
\hrule
That following would appear in the servlet's {\tt web.xml} file;
{\small
\vspace{.2in}
\hrule
\begin{verbatim}
<resource-ref>
<res-ref-name>jms/footopicconnectionfactory</res-ref-name>
<res-type>javax.jms.TopicConnectionFactory</res-type>
<res-auth>Container</res-auth>
</resource-ref>
<resource-env-ref>
<resource-env-ref-name>org_apache_cayenne_access_DataRowStore_foo</resource-env-ref-name>
<resource-env-ref-type>javax.jms.Topic</resource-env-ref-type>
</resource-env-ref>
\end{verbatim}
\hrule
}
This configuration should enable change notification to function.
