Hi Alex, I seem you are sending the message to the direct endpoint before the xml-route is loaded.
Couple of things you may try: 1) Start CamelContext before loading routes 2) Load the camel xml-route with the Camel context (multiple routes can be loaded in the CamelContext, so you just add it to other routes). 3) I personally, when using the Karaf, just drop the files in the deploy folder as explained here: http://liquid-reality.de/Karaf-Tutorial/05/ Raymond On Mon, Sep 26, 2022 at 3:51 PM Domke, Alexander <a.do...@cenit.com.invalid> wrote: > Hello all, > > I am trying to load an external route from a blueprint XML file and it is > not working.
