Starting a Route with a paremeter via JMX

[eric.bender]

Hello, I was wondering if I had a custom MBean I wanted to write which would have a parameter entered in via JMX, what would be the best way to start an existing route and pass it that parameter (via header or some other method).

Just for more information, if I had an MBean with an operation such as:

     @ManagedOperation
     public synchronized String doStuff(String theParam) {
              //What goes here?
        }

And this would need to spawn an existing route such as:

       <osgi:camelContext id="context1" xmlns=...>

              <route id="route1">
                   <from uri="direct:theStart">
                   ....do stuff with the String parameter, header, etc...
              </route> 
      </osgi:camelContext>

I just don't currently understand how I can feed a value form the bean to the route, as well as start the route.  I am guessing it is more obvious if I use a java routebuilder, but I am still hoping for some assistance in getting started.

Yeah XML is much harder because its not a programming language. So it depends really what you want to do with the parameters, if its possible to do.

You can also put together a route in XML from java code and load the route from an input stream as shown here:

http://camel.apache.org/loading-routes-from-xml-files.html

Or have the route as a template in an XML file and then "replace" tokens from the XML file with the parameter, in some java code. And you would need a bit of java code anyway for the JMX operation.

You can also use template langauges like Velocity / Freemarker to build the XML. They have "XML programming" as they have functions you can use in the template files.
