我正在尝试使用xml读取文件,然后使用HTTP4将其发布到URL.但是继续得到以下异常.

我正在使用Apache Camel版本2.11.0,在Linux上使用JDK 1.7

这是代码:

   public static void main(String args[]) throws Exception {
        // create CamelContext
        CamelContext context = new DefaultCamelContext();

        // add our route to the CamelContext
        context.addRoutes(new RouteBuilder() {
            public void configure() {
                from("file:/home/projects/camelinaction-source/chapter1/file-copy/data/templates")
                .convertBodyTo(String.class)
                .setHeader(Exchange.HTTP_METHOD, constant(HttpMethods.POST))
                .to("http4://testserver:8080/rest/test")
                .setHeader(Exchange.FILE_NAME, constant("response.xml"))
                .to("file:/home/projects/hyperlocal");
            }
        });

        // start the route and let it do its work
        context.start();
        Thread.sleep(10000);

        // stop the CamelContext
        context.stop();
    }

这是例外.
