Hello, we are currently trying to upgrade a couple of old Apache Servicemix installations which came pre-bundled with Karaf, ActiveMQ, Camel and Blueprint support. As it seems that Servicemix is no longer maintained, I would like to set up a similar instance with Karaf and the appropriate bundles.
Setup: Karaf 4.3.7 running on openjdk version "17.0.1" 2021-10-19 On a freshly unpacked Karaf instance, I execute the following commands: feature:repo-add activemq 5.16.4 feature:repo-add camel 3.16.0 feature:repo-refresh feature:install activemq-broker feature:install camel-jms feature:install camel-blueprint Running a simple blueprint route (route attached below) that reads from a queue and writes to another queue fails with: 2022-05-05T09:41:46,026 | ERROR | Blueprint Event Dispatcher: 1 | BlueprintCamelContext | 213 - org.apache.camel.karaf.camel-blueprint - 3.16.0 | Error occurred during starting CamelContext: camel-1 org.apache.camel.FailedToCreateRouteException: Failed to create route test: Route(test)[From[activemq://in] -> [Log[PROCESSED MESSAGE],... because of Failed to resolve endpoint: activemq://in due to: java.lang.IllegalArgumentException: wrong number of arguments I found some issues on the web related to that exception but all points refer to packages that I do not use (activemq-camel). I have attached the full stack trace below for completeness. I am pretty sure that this just happens because of lack of knowledge, but I did not find a path out of that problem. So hopefully one of you can point me to the right direction.
