问题 I have written a camel route that polls a file folder, picks up request, checks for memory consumption on server (in a java file). If its below threshold it drops the request on a JMS queue otherwise it throws an exception and picks it again for processing. What i need to do is that when exception is thrown i need to delay processing for a configurable amount of time say 15 mins. This will give some time for server to stabilize instead of keeping it polling unnecessarily. I am using

问题 Two systems are talking to each other through integration(Using apache-camel).

问题 I have several folders on my ftp: /csv /xml /processed /.... How can I rename and move each file once it has been processed from file.csv to file.done and move it to processed folder ?

问题 How does one set the headers for a request made using the http4 component in Camel? The site I'm connecting to requires the referrer header to be set. Using HttpClient directly, one can add headers to the request, but I can't see how that's exposed in Camel. ETA: Working example based on the accepted answer: from("timer://foo?fixedRate=true&delay=0&period=300000") .setHeader("Referer", constant("https://example.com")) .to("https4://www.example.com") 回答1: You should just be able to set it as a

问题 I am writing an application using Akka, Akka-Camel and Spring for configuration. The application needs to act as a standalone JMS client against a variety of application servers, to which end it needs to set up the JMS connection factory using JNDI. I'm testing this with jBoss. I have the same problem with jBoss 5 and 6 (this seems to be a client-side Spring problem, not related to jBoss). I am configuring the Spring beans with this xml: <beans xmlns="http://www.springframework.org/schema
