I'm working with Apache Camel to create route between dynamic endpoints. I
was working with a Main which works but now I need to deploy the application
on an Apache Tomcat server. The problem his that my camel-context doesn't
found my route builder. Here is my applicationContext :
/<bean id="myRoute" class="com.ittb.boa.jis.extractor.MyRouteBuilder">
<constructor-arg name="src" ref="logsFileConnector" />
<constructor-arg name="dest" ref="elasticSearchConnector" />
</bean>
<camelContext id="myCamel"
xmlns="http://camel.apache.org/schema/spring";>
<routeBuilder ref="myRoute" />
</camelContext>/
And I'm getting the following error :
/[ localhost-startStop-1] ContextLoader
ERROR Context initialization failed
org.apache.camel.RuntimeCamelException: org.apache.camel.CamelException:
Cannot find any routes with this RouteBuilder reference:

I've tried to debug it with an EndPoint on configure() in MyRouteBuilder and
the error appears before the breakpoint..
Here is the method configure() which is quite heavy :
/public class MyRouteBuilder extends RouteBuilder {
private ConnectorEndPoint src;
private ConnectorEndPoint dest;
int i = 0;
private String CRON_EXPRESSION_QUARTZ =
CRONGenerator.generateCRONExpression("0/1", "9-17", "?", "*", "MON-FRI");
private MyProcessor processor = new MyProcessor();
RestConsumerFactory consumerFactory = new RestConsumerFactory() {
public Consumer createConsumer(CamelContext camelContext,
Processor
processor, String verb, String basePath, String uriTemplate, String
consumes, String produces, Map<String, Object> parameters) throws Exception
{
return null;
}
};
public MyRouteBuilder(ConnectorEndPoint src, ConnectorEndPoint dest) {
this.src = src;
this.dest = dest;
}
public void configure() {
if (src instanceof ConnectorSQL){
from("quartz2://foo?cron="+ CRON_EXPRESSION_QUARTZ)
.to(src.getRouteFrom())
.bean(processor, "conversionNumericAndDate")
.bean(processor, "standardisation")
.to(dest.getRouteTo());
} else if (src instanceof ConnectorMongoDB){
from("quartz2://foo?cron="+ CRON_EXPRESSION_QUARTZ)
.to(src.getRouteFrom())
.bean(processor, "convertDBObjectToString")
//.bean(processor, "conversionNumericAndDate")
.to(dest.getRouteTo());
} else if (src instanceof ConnectorREST){
from("quartz2://foo?cron="+
CRON_EXPRESSION_QUARTZ).to(src.getRouteFrom())
//.bean(processor, "conversionNumericAndDate")
//.bean(processor, "standardisation")
.to(dest.getRouteTo());
} else if (src instanceof ConnectorXMLFile){
XmlJsonDataFormat xmlJsonFormat = new
XmlJsonDataFormat();
xmlJsonFormat.setEncoding("UTF-8");
xmlJsonFormat.setForceTopLevelObject(true);
xmlJsonFormat.setTrimSpaces(true);
xmlJsonFormat.setSkipNamespaces(true);
xmlJsonFormat.setRemoveNamespacePrefixes(true);
from("file:xml?scheduler=quartz2&scheduler.cron="+
CRON_EXPRESSION_QUARTZ)
.marshal(xmlJsonFormat)
.to(dest.getRouteTo());
} else if (src instanceof ConnectorLogsFile){
ArrayListAggregationStrategy aggregationStrategy = new
ArrayListAggregationStrategy();
from(src.getRouteFrom())
.bean(processor, "lineFilter(${body}, " +
src.getFieldToFilter() +", " +
src.getFirstValue() +", " + src.getSecondValue() + ")")
.split(body().tokenize("\n"))
.filter().method(MyFilter.class, "isValidError")
.bean(processor, "processLogsApplicationSource")
.filter().method(MyFilter.class, "dateFilter(${body}, "
+
src.getFieldToFilter() +", " + src.getFirstValue() +", " +
src.getSecondValue() + ")")
.aggregate(body(),
aggregationStrategy).completionInterval(1000)
.to(dest.getRouteTo());
} else {
System.err.println("Erreur : Type de endpoint en entrée
inconnu");
System.exit(1);
}
}

So, it's like the camel context doesn't launch configure() method so the
RouteBuilder is not created and not found by the context.. My web.xml is :
/ <context-param>
<param-name>contextConfigLocation</param-name>
<param-value>classpath:applicationContext.xml</param-value>
</context-param>
<listener>
<listener-class>org.apache.camel.component.servletlistener.SimpleCamelServletContextListener</listener-class>
</listener>
<listener>
<listener-class>org.springframework.web.context.ContextLoaderListener</listener-class>
</listener>/
I've already create a StackoverFlow question at : here
<http://stackoverflow.com/questions/31161111/apache-camel-routebuilder-in-spring-doesnt-launch-configure>
Thanks for your help !
