copied!<p>Unfortunately, when the slave broker starts so does the CamelContext along with the routes. However you can accomplish this by doing the following:</p> <p>On the camelContext deployed with slave broker add the following autoStartup attribute to prevent the routes from starting:</p> <pre><code><camelContext id="camel" xmlns="http://camel.apache.org/schema/spring" autoStartup="false"> ... </camelContext> </code></pre> <p>Next you need to create a class that implements the ActiveMQ Service Interface. A sample of this would be as follows:</p> <pre><code>package com.fusesource.example; import org.apache.activemq.Service; import org.apache.camel.spring.SpringCamelContext; import org.slf4j.Logger; import org.slf4j.LoggerFactory; /** * Example used to start and stop the camel context using the ActiveMQ Service interface * */ public class CamelContextService implements Service { private final Logger LOG = LoggerFactory.getLogger(CamelContextService.class); SpringCamelContext camel; @Override public void start() throws Exception { try { camel.start(); } catch (Exception e) { LOG.error("Unable to start camel context: " + camel); e.printStackTrace(); } } @Override public void stop() throws Exception { try { camel.stop(); } catch (Exception e) { LOG.error("Unable to stop camel context: " + camel); e.printStackTrace(); } } public SpringCamelContext getCamel() { return camel; } public void setCamel(SpringCamelContext camel) { this.camel = camel; } } </code></pre> <p>Then in broker's configuration file, activemq.xml, add the following to register the service:</p> <pre><code><services> <bean xmlns="http://www.springframework.org/schema/beans" class="com.fusesource.example.CamelContextService"> <property name="camel" ref="camel"/> </bean> </services> </code></pre> <p>Now, once the slave broker takes over as the master, the start method will be invoked on the service class and the routes will be started.</p> <p>I have also posted a blog about this here: <a href="http://jason-sherman.blogspot.com/2012/04/activemq-how-to-startstop-camel-routes.html" rel="nofollow">http://jason-sherman.blogspot.com/2012/04/activemq-how-to-startstop-camel-routes.html</a></p>
