Steps to replace a direct call by a JMS proxy?

Hi,

I currently have a Java application that sends directly messages to a queue
using a Spring JmsTemplate:

I would like to take advantage of the facilities of Camel Throttling but I
do not see how to define my route. Could someone help me and tell me what I
have to do?

Regards,
Al. F

You just send to "direct:endpoint". This will trigger the route 
Christian Posta described and the throttling should work.

You can of course not directly define the throttling in the 
producerTemplate as you only can define an endpoint uri. For this case 
we have the direct endpoint that can then nicely bridge to an existing 
route without any further indirection.

Thank you.

As a first step, I would like to get it working using a template. When done,
Maybe I'll separate the logic in a separate bean.

But... How to make throttling with using a producertemplate? Is is possible?

Thanks,
Al. F

There is one additional thing you need. You have to call your route in 
some way.

There are two methods:
1. camelContext.createProducerTemplate().sendBody or similar
2. pojo messaging: http://camel.apache.org/pojo-messaging-example.html

Depending on your application it may make sense to use pojo messaging to 
separate your business code from the camel framework.

May want to take a look at some of the intro material:
http://camel.apache.org/getting-started.html

Essentially, you'll need to define a route builder that a builds a route
like:

from("direct:endpoint").throttle().to("jms:queueName")
