I am trying to write a simple "ping" application. I ping urls in a multicast
and if there is a connection exception I catch it in a onException which
calls a aggregation that builds an email
If myFirstURLToPing is down I can't figure out out how to pass the URL via
the Exception to the email body.
I can't find something like ${to.uri} in the Message or Exchange. This seems
that it should be easy to get from the exception but I can't find any
references to the uri variable.
<route >
<from uri="timer://foo?fixedRate=true&period=3600000"
id="pingTine"/>
<multicast>
<to http://myFirstURLToPing:1234"; />
<to http://mySecondURLToPing:1234"; />
<to http://myThirdURLToPing:1234"; />
</multicast>
</route>
<onException useOriginalMessage="true">
<exception>java.net.ConnectException</exception>
<exception>java.net.UnknownHostException</exception>
<handled>
<constant>true</constant>
</handled>
<transform>
<simple>DOWN >>> <HERE SHOLD the URI BE
DISPLAYED></simple>
</transform>
<to uri="direct:buildEmaiBody"/>
</onException>
<route>
<from uri="direct:buildEmaiBody"/>
<aggregate strategyRef="mailBodyAppender" strategyMethodName="append"
completionTimeout="20000">
<correlationExpression>
<constant>true</constant>
</correlationExpression>
<to smpt://.../>
</aggregate>
</route>
I would want my email to show
DOWN >>> http://myFirstURLToPing:1234
DOWN >>> http://myThirdURLToPing:1234
I have figured out a way by creating a route for each URL to ping, naming
the route the same as the URL to ping and then use ${routeId} but that seems
very clumpsy
