Apache Camel Scheduler error: Failed to resolve endpoint

Question

I am trying to use "Scheduler component- http://camel.apache.org/scheduler.html but I am getting error. I need to fire scheduler every 60s and call my bean. I picked up the example from documentation and tried to implement it as is but it fails.

public class SchedulerRoute extends RouteBuilder {
@Override
public void configure() throws Exception {
    from("scheduler://foo?period=6000&delay=50").to("bean:logBean?method=sayHello");
}}

I get this error:

org.apache.camel.FailedToCreateRouteException: Failed to create route route2: Route(route2)[[From[scheduler://foo?period=6000&delay=50]] -... because of Failed to resolve endpoint: scheduler://foo?delay=50&period=6000 due to: Failed to resolve endpoint: scheduler://foo?delay=50&period=6000 due to: There are 1 parameters that couldn't be set on the endpoint. Check the uri if the parameters are spelt correctly and that they are properties of the endpoint. Unknown parameters=[{period=6000}]

I tried TIMER component and that works flawlessly but not the scheduler.

THIS CODE WORKS WITH TIMER COMPONENT

public class SchedulerRoute extends RouteBuilder {
@Override
public void configure() throws Exception {
    from("timer://foo?fixedRate=true&period=6000").to("bean:logBean?method=sayHello");
        }}

Any ideas what am I missing here?

Answer 1

That was a mistake in the scheduler documentation. There is no option named period . You should use delay to set how often to trigger. I am updating the documentation now, so the website is correct next time its generated.

http://camel.apache.org/scheduler

This is also what the exception message tells you: Unknown parameters=[{period=6000}
