RE: Passing parameters from routes to components

Re properties...

Sure, there is a long description at http://camel.apache.org/properties.html

There are a number of mechanisms for getting the properties injected, depending 
on how you package and deploy your application.  Here is one discussion:
http://stackoverflow.com/questions/19457818/how-do-i-load-a-camel-property-into-a-bean

Also, I have some code that loads properties that are used in a route I define 
in Java DSL. Like this:

public class Routes extends RouteBuilder {
// URI to send requests to.
@PropertyInject("backendUri")
private String backendUri;

private void validateNeededProperties() throws Exception {
if (backendUri == null)
throw new BadConfigurationException("backendUri is not set");
}

@Override
public void configure() throws Exception {
validateNeededProperties();
...
   from(INVOKE_BACKEND_URI).routeId(INVOKE_BACKEND_ROUTE_ID)
.to(backendUri)

You could inject property values from outside the routes.
