Camel integration with existing web application - apache-camel

Question

I have a web application providing rest full service and another standalone (jar) application doing soap request response (using camel)
Can someone give me pointers to me for how to integrate the two applications
Specifically around how to kick camel routes when war file is deployed in tomcat, and how to re-run the routes when a specific HTTP request arrives.
I am using camel DSL (xml) and spring.
UPDATE 1:
I have followed this
Checked that web.xml has following lines:
<context-param>
<param-name>contextClass</param-name>
<param-value>org.springframework.web.context.support.AnnotationConfigWebApplicationContext</param-value>
</context-param>
<context-param>
<param-name>contextConfigLocation</param-name>
<param-value>com.mycompany.server.Binder</param-value>
</context-param>
<context-param>
<param-name>log4jConfigLocation</param-name>
<param-value>/WEB-INF/classes/log4j.properties</param-value>
</context-param>
<listener>
<listener-class>org.springframework.web.context.ContextLoaderListener</listener-class>
</listener>
Created a /WEB-INF/applicationContext.xml file and put all my routes and beans in it (btw I have beans.xml file as well in src/main/resources which is getting read by spring).
<?xml version="1.0" encoding="UTF-8"?>
<beans

<bean id="serviceGetAccountResponseProcessor" class="com.mycompany.service.serviceGetAccountResponseProcessor"/>
</beans>
Up the logging level of log4j.logger.org.apache.camel=DEBUG
However do not see any camel log lines of routes starting.
Update 2:
I was not doing mvn clean generate-sources.
Once I started doing mvn clean and rebuilding the war file, camel kicked in.

Seems your spring context does not really fire. Make sure it is!
There should be some Spring info log events telling you about this.
Try adding this:
<context-param>
<param-name>contextConfigLocation</param-name>
<param-value>/WEB-INF/applicationContext.xml</param-value>
</context-param>
