Unfamiliar syntax

[Garry <gm...@hotmail.com>]

Hi,

A basic question: while working through various examples, I've come across
constructs like this:

 from("timer:myTimerEvent?fixedRate=true")
           .setBody(constant("Helloworld!"))
           .to("log:org.apache.servicemix.samples.camel.ExampleCamelRoute");

What is the syntax "timer:myTimerEvent?fixedRate=true" and where is it
defined?

Thanks, Garry

Garry,

You are looking at an Apache Camel route, specified in the fluent API.  
This particular example uses Camel's Timer component 
(http://activemq.apache.org/camel/timer.html) for sending messages to 
the Log component (http://activemq.apache.org/camel/log.html).  This 
kind of route can be deployed using the servicemix-camel JBI component.

You can however also use ServiceMix and Camel together.  For instance, 
you can use to implement EIP (look at 
http://servicemix.apache.org/replacing-tutorial-eip-su-with-tutorial-camel-su.html 
for an example).

Regards,

Gert
