Camel Processor not setting headers

Question

I am not able to inject/modify headers in a processor using the below spring DSL config. Could you please help in figuring out what I am doing wrong?

    <routeContext xmlns="http://camel.apache.org/schema/spring"
    id="routes1">

    <route id="sdPoll" de:name="Polling"
        de:systemName="Polling" streamCache="true">
        <from uri="timer://sdPoll?fixedRate=true&amp;period=60000" />
        <process ref="refProcessor" />
        <to uri="http://dummyhost" />
        <to uri="log:DEBUG?showBody=true&amp;showHeaders=true" />
    </route>
</routeContext>
<bean id="refProcessor"
    class="com.abc.de.RefProcessor" />

Processor class

public class RefProcessor implements Processor {

private final Logger log = Logger.getLogger(RefProcessor.class);

@SuppressWarnings("unchecked")
@Override
public void process(Exchange exchange) throws Exception {

    exchange.getIn().setHeader("Authorization", "TODO");
    exchange.getIn().setHeader("CamelHttpMethod", "POST");
    exchange.getIn().setHeader("CamelHttpUri", "http://localhost:8280/api/check");
    exchange.getIn().setHeader("Content-Type", "application/json");
    exchange.getIn().setHeader("Accept", "application/json");
    exchange.getIn().setBody("TODO");

    //exchange.getOut().setHeaders(exchange.getIn().getHeaders());
    //exchange.getOut().setHeader("Authorization", "TODO");
    //exchange.getOut().setBody("TODO");
 }
}

Java DSL seem to work though! So what is wrong with my Spring DSL config

static RouteBuilder createRouteBuilder3() {
    return new RouteBuilder() {
        public void configure() {
            from("timer://timer1?period=60000").process(new Processor() {
                public void process(Exchange exchange) throws UnsupportedEncodingException {
                    exchange.getIn().setHeader("CamelHttpMethod", "POST");
                    exchange.getIn().setHeader("Content-Type", "application/json");
                    exchange.getIn().setHeader("Accept", "application/json");
                    exchange.getIn().setHeader("CamelHttpUri",
                            "http://localhost:8280/api/check");
                    exchange.getIn().setHeader("Authorization", "TODO");

                    exchange.getIn().setBody("TODO");
                }
            }).to("http://dummyhost").to("log:DEBUG?showBody=true&showHeaders=true");
        }
    };
}

Your Processor looks ok.

Just a wild guess, but do you use routeContext in your XML configuration intentionally? If not, can you try to switch to camelContext?

See http://people.apache.org/~dkulp/camel/configuring-camel.html for the difference between routeContext and camelContext
