Is there a tools to convert java dsl to xml ?
hi team,
Is there a tools to convert java dsl to xml ?
Is every java dsl code have a equal xml counterpart?
When I am reading the camel document's , there are many snippets code that
writen by java dsl .
As a new user , sometimes I have to use xml instead of java dsl .
In fact , I want to know how could I convert the below code to xml
from("direct:start")
.setHeader("decisionSlip").method(OrderProcessorBean.class,
"calculateRoute")
.routingSlip("decisionSlip");
thanks.

I was playing with just this a few weeks ago. Here's an example of what
I got working.
The one gotcha I encountered was that you can't use beans inline in the
Java DSL. Instead you need to put the bean in the registry and reference
it from there. Other than that it seems to work "as expected".

// generate route 2 and convert to XML
RoutesDefinition routes = new RoutesDefinition()
RouteDefinition route = routes.route()
route.from("timer://foo?fixedRate=true&period=200")
route.log("Hello from Java!")
route.processRef("simpleProcessor2") // the reference to the bean in the
registry
String xml2 = ModelHelper.dumpModelAsXml(null, routes)
println xml2
// create and start context
long t0 = System.currentTimeMillis();
SimpleRegistry registry = new SimpleRegistry()
CamelContext camelContext = new DefaultCamelContext(registry)
camelContext.start()
long t1 = System.currentTimeMillis();
System.out.println("Camel Context creation took " + (t1 - t0));
// add beans to the registry

Hi
At runtime you can output any Camel route as xml, there is api on
camel context or jmx api to do so.
This is what tooling such as the camel commands / hawtio etc uses to
visualize the running routes.

I'm the opposite. I avoid XML, and use Java DSL exclusively. I really like
the way it reads, and easy to test using camel test

I also am a new user and tend to like XML. Maybe that will change as I get
used to Camel.
I don't know of any automated way, but you can get edit access to camel and
make the changes yourself:

I should also say that there is a runtime tool that allows you to see the XML
of running routes - HawtIO (http://hawt.io).

Hi,

No, although you can see an XML representation of a route defined in any DSL
(Java, XML, Groovy, Scala etc.) by calling a method called dumpRouteAsXml()
when looking at it though JMX.

Yes it does. A good reference (shameless self-promotion) is the Apache Camel
Developer's Cookbook - it contains examples of every DSL element in both the
Java and XML DSLs.

<from uri="direct:start">
<setHeader name="decisionSlip">
<method ref="myOrderProcessorBean" method="calculateRoute"/>
</setHeader>
<routingSlip>
<header>decisionSlip</header>
</routingSlip>
Hope that helps.
