How to call processor thru configuration file ?

My application needs to work as middleware where it has got orders(in form of
xml) from various customers which contains the
supplier id where custmers can send the xml to one of these components

1)JMS queue
2)File system
3)HTTP
4)Web service request(rest/soap)

Once it get the order, it needs to send order request to different suppliers
in the form of xml.Somehow i spotted
http://java.dzone.com/articles/open-source-integration-apache and looks like
its provides the perfect solution.
My question is :-

At the link in Figure 3, How can I introduce my OrderService in between
output of marshalling(which is POJO here) and order queue
output of marshalling -----------> OrderService(instead of order
queue)-------------->orderQueue

Probably i

<route id="NormalizeMessageData">
<from uri="jms:incomingOrders" />
<convertBodyTo type="java.lang.String" />
<choice>
<when>
<simple>${body} contains '?xml'</simple>
<unmarshal>
<jaxb contextPath="org.fusesource.camel" />
</unmarshal>
<to uri="jms:orders" />
</when>
<otherwise>
<unmarshal>
<bindy packages="org.fusesource.camel" type="Csv" />
</unmarshal>
<to uri="jms:orders" />
</otherwise>
</choice>
</route>

How will i route the output to process() method my processor
class(MyOrderProcessor) in above configuration?

Once call goes to process() method MyOrderProcessor, i want to put output of
process() method on JMS Queue?
