Depending on the registry you use you can create the beans in java and add

Yes, that's what I figured. Its the exact mechanism for doing so that
I'm trying to figure out.
I have some example code on how to do this using a spring registry. However
since you say you are not using spring you will have to figure out how to
add the beans programmatically to the registry implementation you are
using.
I'm not currently using spring, but I could do so if there was a good
reason too.
Performance is a key issue. I'm finding that creating a new Spring
ApplicationContext including Camel from XML is fairly slow (about 1.3s),
whilst creating a new Camel context directly in Java (no Spring) is
quite a bit faster (about 0.3s) whilst adding a new route to a running
context is superfast (about 0.01s), hence the preferred option.

I need to provide the route definition plus any beans it uses at
runtime, after the context has started.

Hi
If you are using spring xml then the beans need to go in the spring
xml file as <bean>.
You may be able to add those beans later using some spring java api.

Sorry, not clear on this. Where does the <bean> element go?
The XML generated from the route looks like this:
<?xml version="1.0" encoding="UTF-8" standalone="yes"?>
<routes xmlns="http://camel.apache.org/schema/spring";>
<route>
<from uri="timer://foo?fixedRate=true&period=200"/>
<log message="Hello World!"/>
<process ref="mybean"/>
</route>
</routes>
The <bean> element would normally be part of the spring XML, but
outside the
routes definition looking something like this:
<?xml version="1.0" encoding="UTF-8"?>
<beans ...>
<bean id="mybean" class="org.foo.MyBean"/>
<camelContext xmlns="http://camel.apache.org/schema/spring";>
<route>
....
</route>
</camelContext>
</beans>
Can the beans be defined in this way at runtime or is some other
mechanism
needed to instantiate the beans and add them to the registry
independently
of adding the route (as XML)?

Yes, but how to specify the bean that is referenced? Can that be

in the XML using a bean element as if it was being using on startup,
or
does
it need to be added to the registry "manually"?

Hi,
I'm wanting some guidance on how to generate a route definition
using
the
API in a way that allows it to be converted to XML and then
executed.
I've
got the basics sorted, but struggling on how to handle processors
and
beans.
For instance, if I generate a route like this:
// generate the route
RoutesDefinition routes1 = new RoutesDefinition()
RouteDefinition route = routes1.route()
route.from("timer://foo?fixedRate=true&period=200")
route.log("Hello World!")
route.process(new SimpleProcessor())
// set route to context
CamelContext camelContext = new DefaultCamelContext()
camelContext.start()
camelContext.addRouteDefinitions(routes1.getRoutes())
Then the route works fine (e.g. my SimpleProcessor gets called as
expected).
But if I generate the XML definition of the route it looks like
this:
<?xml version="1.0" encoding="UTF-8" standalone="yes"?>
<routes xmlns="http://camel.apache.org/schema/spring";>
<route>
<from uri="timer://foo?fixedRate=true&period=200"/>
<log message="Hello World!"/>
<process/>
</route>
</routes>
e.g. the processor definition has been lost.
I suspect I need to register the processor bean with the registry
and
use
the processRef() method on the route, or something along those
lines.
Does anyone have any examples of how to handle this?
Yes for representing this as xml, you would need to use a ref for the
processor
Thanks
