JMS with apache camel in ServiceMix generates an error

I've got a problem with JMS access in spring, I try to configure JMS consumer and get an error:

Class org.springframework.core.task.SimpleAsyncTaskExecutor does not implement the requested int开发者_运维百科erface java.util.concurrent.Executor

Does any one know how to solve this, or what this really means? I'm using Camel 2.4 and am deploying my service to ServiceMix 3.3.

I am assuming you are using Spring 2.x.

It seems that Spring 2.x SimpleAsyncTaskExecutor does not implement the Java core Executor interface. To resolve this, you have 2 options I can think of right off the bat:

1. Upgrade to Spring 3.x. That version of SimpleAsyncTaskExecutor does implement the Executor interface.
2. Use a different Executor implementation. Java core has the built in ThreadPoolExecutor, or you can use the ExecutorService to construct a variety of different configurations of the same.

Hope that helps.

You could maybe recompile camel-jms using spring 2.5 which oddly may help. Check camel building source docu as there is a maven profile to use spring 2.5.
