Apache camel file component not moving files - apache-camel

Question

I'm using apache camel 2.12.1 to create a route and then move some files in my local directory, the exmple runs fine but the files are never moved, this is the code for the class.
public class MoveFilesTest {
private static final Log LOG = LogFactory.getLog(MoveFilesTest.class);
public static void main(String args[]) throws Exception {
LOG.debug("create CamelContext");
CamelContext context = new DefaultCamelContext();
// add our route to the CamelContext
context.addRoutes(new RouteBuilder() {
File file = null;
public void configure() {
from("file:data/inbox?delay=100&noop=true")
.process( new Processor() {
public void process(Exchange msg) throws Exception {
File file = msg.getIn().getBody(File.class);
LOG.debug("Processing file: " + file.getName());
}
})
.to("file:data/outbox").end();
}
});
LOG.debug("start the route and let it do its work");
context.start();
context.stop();
}
}
as a note, this code just to work, now i'm working on mac os x 10.7, this is the debug log. i added the noop=false and the delete=true, but the result is the same. thank you

Answer 1

Yes, you start Camel and stop it immediately. So, when you put a file to a folder. It wont process cuz camel is already stopped.
Camel contains Main implementation to keep Camel running in standalone application.
There is link: http://camel.apache.org/running-camel-standalone-and-have-it-keep-running.html

Answer 2

CamelContext.start does not block, so basically you are starting the context and then immediately stopping it. You need to wait or block on something until the context should stop. You can reference this thread for some ways of doing this.

Answer 3

I had a similar problem but that was to do with streamCaching() not getting set properly and so the code below was failing
context.getStreamCachingStrategy().setSpoolDirectory(spoolDirectory);
from(uri.toString()).streamCaching().to(destination);
I set the Streaming directly on CamelContext and that solved the problem
CamelContext context = getContext();
context.setStreamCaching(true);
context.getStreamCachingStrategy().setSpoolDirectory(localSpoolDirectory);
context.getStreamCachingStrategy().setSpoolThreshold(Long.parseLong(spoolThreshold.trim()));
context.getStreamCachingStrategy().setBufferSize(Integer.parseInt(bufferSize.trim()));
