Camel

[cvasilak]

Hi there,

first of alI,  I am a newcomer to switchyard and camel so please bear with me

I am starting a new project here at work which will be based on messaging(JMS) together with some native C clients (STOMP). I really like the Camel project and its implementation of the EIP patterns. For sure will save me with a lot of work down the road... implementing recipient list, aggregator etc etc.

I am trying to find how to deploy camel routes inside a jboss 7. As I understand from the camel documention your routes need to be packaged in a War together with spring (which I want to avoid) if you intend to use it on an app server (define a listener that bootstraps camel but depends on spring). Because switchyard uses camel internally together with a @Route annotation and because it comes with support of jboss 7 I thought it can be used to define my routes

Byt trying an example with

    public void configure() {

        from("jms:svc_rrd")

        .log("Received message from queue/svc_rrd : ${body}");

    }

failed with exception

Endpoint URI on route jms:svc_rrd does not match expected URI : switchyard://MyCamelService?namespace=urn%3Aswitchyard%3Aapplication%3AswitchyardDemo

So I want to ask the developers if I am doing something wrong....

My other option is to use camelpe that utilizes CDI to bootstrap camel and also support route definitions through annotations.

Thanks for your time

Hey Christos,

Camel can be used in two ways in SwitchYard:

- As a routing service

- As a gateway binding provider

In your case it looks like you want to do both, i.e. create a routing service using Camel and then expose that service using a Camel JMS gateway binding.  One requirement for routing services in SwitchYard is that the "from" endpoint should always point to a logical endpoint name.  Check out this for an example:

https://github.com/jboss-switchyard/quickstarts/blob/master/camel-service/src/main/java/org/switchyard/quickstarts/camel/service/JavaDSLBuilder.java

After that, you want to add a Camel gateway binding to the application configuration (switchyard.xml).  An example of what that looks like can be found here:

https://github.com/jboss-switchyard/quickstarts/blob/master/camel-jms-binding/src/main/resources/META-INF/switchyard.xml

Not sure if you have tried the Forge tooling support for SwitchYard, but you should be able to create the route and add the binding with Forge in about 30 sec.  Let me know if you run into a problem and I'll post an example.

cheers,

keith

Hello Keith,

thanks a lot for your response. After carefully examining the examples you post it and together with Forge, I did manage to work it out! and works beautifully!

I am still learning about switchyard but I think I am in a good path and have a starting point to work

Thanks again
