Connecting Custom camel component to remote provider on-startup

Hi guys,

I have a custom component which I have written, I intend to connect to a
remote service provider over a protocol which I have implemented in my camel
component producer.

I connect to the remote service with the help of CustomProducer which
extends DefaultProducer.
I overruled the doStart function in the base class wherein I asked the
component to establish a connection to the remote provider.

However, I noticed that whenever I start the custom component, it never
connects to the remote entity until a message is sent to the custom
component's endpoint?

How do I make sure it connects at start up?

kr.

Here is a sample of camel applciation I wrote:

<osgi:camelContext xmlns="http://camel.apache.org/schema/spring"
trace="true">
  	<endpoint id="myCustomEndpointRef"
uri="customProtocol://${server-ip}:${server-port}/service"/>
    <route>
    	<from uri="nmr:myCustomEndpoint"/>
        <to ref="myCustomEndpointRef"/>
    </route>
  </osgi:camelContext>


This does not call start, because I purposely logged the function. (It is
called when message is sent to the exchange).

Hi

You can call start on your producer.
But Camel would normally do that for you if you use it from a Camel route.

How do you use your custom component?
