Dynamic Route Creation.

[Syed <ss...@qatarairways.com.qa>]

Hi 

I am trying to create the routes dynamically in
*addRoutesToCamelContext(CamelContext context)*  method, instead of
configuring the routes in the configure() method.  Reason is, I have to
fetch the routes from the database instead of static configuration.

the below similar example of Java DSL, I created using RouteDefinition and
added the route definition into the camel context.

Java DSL
-----------

from("jms:queue:eix.sorter.queue")
             .process(new com.qr.eix.processor.SorterProcessor())
             .process(new com.qr.eix.processor.SorterProcessor1()).choice()
	.when()
                .simple("${body.msgType} == 'FFR'")
	 .to("jms:queue:eix.ffr.queue")
                 .when()
	 .simple("${body.msgType} == 'FFM'")
	 .to("jms:queue:eix.ffm.queue")
                .otherwise()
	 .to("jms:queue:eix.parser.queue");

Similar Dynamic Routes
----------------------------

RouteDefinition rDefintion = new RouteDefinition();
rDefintion.from(from);
rDefintion.process(new com.qr.eix.processor.SorterProcessor());
rDefintion.process(new com.qr.eix.processor.SorterProcessor1());
rDefintion.choice().when().simple(buildFFRString);
rDefintion. to(ffrto)
rDefintion.choice().when().simple(buildFFMString);
rDefintion.to(ffmto)
rDefintion.choice().otherwise();
rDefintion.to(generalTo)

With the above CBR is not working and i am not getting the print statements
inserted inthe processor class..let me know where i am wrong...

Thanks 
Jawahar

Have you consider using RecipentList [1] or DynamicRouter [2] for this
purpose? It's definitely easier to use and far more maintainable than
creating new routes.

Good to hear that. Better stick to the EIP (Dynamic Router, Recipient
List, etc) than to low-level Camel API.

All you need to do is use ModelCamelContext interface instead of CamelContext.

ModelCamelContext context = new DefaultCamelContext();
context.addRouteDefinition(...);

Route definition API has been moved to more specialized interface, as
not every CamelContext implementation need to support route
manipulation (although DefaultCamelContext does so).

Laters.

Thanks, I am able to configure as you said...

let me know whether i can use context.addRouteDefinitions(routeList). 
addRouteDefintions method shows as deprecated..

I define my routes in accordance with information read from a database.

I do not understand why spas you can not do in configue.

I read the startup route definition in the database (init routebuilder)
then I give the hand to "configure" which according to the definition read
built the road.

Must be attentive to your classes of objects.

you can not use the object as it 

I do not know all classes but your Ide can help you

you must also pay attention to optinals end() (on choise when pipeline etc.)


java DSL is a fluent API.
But each method returns a different object and different class. 
for exemple .choice() return a ChoiceDefinition


it is necessary to retrieve the returned object to chain the following
method.
