Hi Bruno, I somtime encountered the error Content not allowed in prolog. This always happened when the xml parser read a file that contained no valid xml. So it seems to me you have a file output.txt somewhere that is read and contains no valid xml.
You could try to put a bean after from that simply receives an Exchange in a method. So you can debug into this and see where the file comes from.

I have a route defined in Spring as this : <!-- ActiveMQ beans and usual stuff --> <bean id="uploadBean" class="be.ucm.career.quarterly.upload.UploadBean"/> <camel:camelContext xmlns="http://camel.apache.org/schema/spring";> <camel:package>foo.bar</camel:package> <camel:route> <camel:from uri="file:src/data?noop=true&delay=30000" /> <camel:bean ref="uploadBean"/> <camel:to uri="jms:output" /> </camel:route> </camel:camelContext> The implementation of "uploadBean" : public class UploadBean { @Handler public String upload(@XPath("configuration/loopCount/text()")String chunkSize) { System.out.println("Chunk size is : " + chunkSize); return "FOO_123"; } } When launching the project with "mvn camel:run", I get this : [...] // INFO output [...] Chunk size is : 100 [src/data?delay=30000&noop=true] BrokerService INFO Using Persistence Adapter: AMQPersistenceAdapter(activemq-data\localhost) [src/data?delay=30000&noop=true] AMQPersistenceAdapter INFO AMQStore starting using directory: activemq-data\localhost [src/data?delay=30000&noop=true] KahaStore INFO Kaha Store using data directory activemq-data\localhost\kr-store\state [src/data?delay=30000&noop=true] AMQPersistenceAdapter INFO Active data files: [1] [src/data?delay=30000&noop=true] BrokerService INFO ActiveMQ 5.2.0 JMS Message Broker (localhost) is starting [src/data?delay=30000&noop=true] BrokerService INFO For help or more information please see: http://activemq.apache.org/ [ JMX connector] ManagementContext INFO JMX consoles can connect to service:jmx:rmi:///jndi/rmi://localhost:1099/jmxrmi [src/data?delay=30000&noop=true] KahaStore INFO Kaha Store using data directory activemq-data\localhost\kr-store\data [src/data?delay=30000&noop=true] BrokerService INFO ActiveMQ JMS Message Broker (localhost, ID:100WCTI150-2821-1278413932666-0:0) started [src/data?delay=30000&noop=true] TransportConnector INFO Connector vm://localhost Started [src/data?delay=30000&noop=true] TransportConnector INFO Connector vm://localhost Stopped [src/data?delay=30000&noop=true] BrokerService INFO ActiveMQ Message Broker (localhost, ID:100WCTI150-2821-1278413932666-0:0) is shutting down [src/data?delay=30000&noop=true] BrokerService INFO ActiveMQ JMS Message Broker (localhost, ID:100WCTI150-2821-1278413932666-0:0) stopped [Fatal Error] output.txt:1:1: Content is not allowed in prolog.
