Re: How to keep route running on camel with JavaDSL?
Hey guys, I want to thank for all the help and suggestions. However I got an answer from someone else at stackoverflow that suggested I should use this: http://camel.apache.org/running-camel-standalone-and-have-it-keep-running.html After that I decided to check the Camel in Action book and I just finished reading chapter 13.4.1 where they also talk about using this Java class. I am a little confused with the differences between the start() and run() methods, so I checked documentation here: http://camel.apache.org/maven/current/camel-core/apidocs/org/apache/camel/main/Main.html But I could not find anything that would explain it to me. Anyway, I am now using it and I must say it sure is a lot easier than I expected ! -- View this message in context: http://camel.465427.n5.nabble.com/How-to-keep-route-running-on-camel-with-JavaDSL-tp5742677p5742727.html Sent from the Camel - Users mailing list archive at Nabble.com.
Re: How to keep route running on camel with JavaDSL?
start() is the method from Camel Service interface, so you can think it just start the services of camel. But run() need to do some addition work after calling the start() method, such as block the main thread to avoid exiting the process and do some clean up work after camel is shutdown. -- Willem Jiang Red Hat, Inc.

report, they change it and send it back to the loadbalancer, which then
print the body of the report.

.end();
}
}
);
context.start();
}

However, once I execute the loadbalancer it finishes immediately. I tried
fixing this problem by adding an infinite loop after the context.start()
call, however this is a terrible solution because the program will simply
get stuck on the loop and will stop generating reports and sending them.
How do I fix this? How do I keep my loadbalancer running while being able to
generate requests and print the reports that it receives?

Re: How to keep route running on camel with JavaDSL?
When you start the camel route in the main, you need to add a sleep to block
the main thread from exit.
BTW, you can use other tools that camel provides to running the camel route as
Claus just showed you.
