how to get CamelContext using Spring

[shekher awasthi <sh...@gmail.com>]

Hi All,

i am trying to use camel in my spring based  web-application here is the
entries from my web.xml

 <?xml version="1.0" encoding="UTF-8"?>
    <web-app version="2.4">
    <servlet>
        <servlet-name>dispatcher</servlet-name>
        <servlet-class>
            org.springframework.web.servlet.DispatcherServlet
        </servlet-class>
        <load-on-startup>2</load-on-startup>
    </servlet>
<listener>

<listener-class>org.springframework.web.context.ContextLoaderListener</listener-class>
  </listener>

    <servlet-mapping>
        <servlet-name>dispatcher</servlet-name>
        <url-pattern>*.*</url-pattern>
    </servlet-mapping>
</web-app>
my applicationContext.xml file is something like this

<?xml version="1.0" encoding="UTF-8"?>
<beans xmlns="http://www.springframework.org/schema/beans"
       xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance"
       xmlns:context="http://www.springframework.org/schema/context"
       xsi:schemaLocation="
       http://www.springframework.org/schema/beans
       http://www.springframework.org/schema/beans/spring-beans-2.5.xsd
       http://www.springframework.org/schema/context
       http://www.springframework.org/schema/context/spring-context-2.5.xsd
       http://camel.apache.org/schema/spring
       http://camel.apache.org/schema/spring/camel-spring.xsd">
  <camelContext xmlns="http://camel.apache.org/schema/spring">
    <route>
      <from uri="seda:foo"/>
      <to uri="mock:results"/>
    </route>
  </camelContext>
</beans>

when i am starting my application it is showing that camel context has been
started and it has detected one route,now i want to execute a process where
camel should read this route and than start
process and complete the route as per configuration.But i am not sure how
can i get regrence of the camel context since if i create a new instance of
camelContext inside my java class
that means i am creating a new context and not the one i initiated using
spring,can any one suggest me a way to do it so that i can get refrence of
the existing camelContext being created by the Spring
so that i can take advantage of it.
Thanks in advance

Hi,
     Please give a "id" to the CamelContext. you can grab it using the
Spring's getBean method.
For example if you give the following camle context code inside your springs
application context xml then
you can get the "FIRST-CAMLE-CONTEXT" using the getBean() method

<camelContext id="FIRST-CAMEL-CONTEXT"
xmlns="http://camel.apache.org/schema/spring">
	<route>
		<from uri="direct:startReading" />
		<bean ref="myBean" method="readAndPint" />
	</route>
</camelContext>

<bean id="myBean" class="com.anver.test.ReadBean" />


public static void main(String[] args) throws Exception { 
   ApplicationContext context = new
ClassPathXmlApplicationContext("META-INF/spring/camel-context.xml");
   CamelContext camelContext = (CamelContext)
context.getBean("FIRST-CAMEL-CONTEXT");	        
   System.out.println(camelContext.getEndpoints());
}

Hi

Sounds like you want to implement CamelContextAware [1]
