Thanks Claus, However, I can't get it to work properly. The VetoCamelContextStartException I throw has rethrowException=false, since I don't want a stacktrace printed. But that seems to cause Camel to get stuck during "shutdown". It prints the message about the veto, but then nothing happens, and the process doesn't terminate.
When debugging this in Eclipse it seems to get stuck in the method waitUntilCompleted() in org.apache.camel.main.MainSupport. When using rethrowException=true all works fine, but as I said, I don't want to use this because I don't want the stacktrace, only the message. Is this a known bug? /Jimi ________________________________________ From: Claus Ibsen <[email protected]> Sent: Sunday, April 17, 2016 11:30 AM To: [email protected] Subject: Re: Trigger sanity check on startup, camel style? You can implement an LifecycleStrategy, and then impl the callbacks for onContextStart and there you can do your check and fail with the VetoCamelContextStartException that gets logged as a WARN and stop Camel from starting.
