Re: date functions/URL params for http endpoint

[Bharat Goyal <bh...@adchemy.com>]

When we defined the processor as mentioned  above:
public class MyProcessor implements Processor {
    ProducerTemplate producer;
......
    public void process(Exchange exchange)
    {
URI uri = ... (dynamic params used)
........
        producer.send(uri, exchange);
    }


in spring xml:
        <route id="http-my-route" >
          <from uri="direct:start"/>
          <to uri="myHttpProcessor"/>
          <to uri="log:newxml"/>
        </route>

When running this, we don't see anything in the log - expected xml from the specified uri="http://..... The process method doesnt seem to get called.

You can add an ID to your route and start it and stop it using the ID.

Your route would be

from(endpoint)
  .routeID(idString)
  .process(whatever);

You can then use camelcontext.stopRoute(idString) to stop the route
and camelcontext.startRoute(idString) to re-start it.
