Using the latest version of servicemix: Apache ServiceMix 3.2.1 in a Linux environment.
I'm following the tutorial #3 ( http://servicemix.apache.org/3-beginner-using-apache-camel-inside-servicemix.html Beginner - Using Apache Camel inside ServiceMix ) step by step and was able to successfully deploy the SA without any issues. tutorial-camel-sa]# mvn jbi:projectDeploy -DforceUpdate=true This is great and works! ServiceMixLog: ---------------- INFO - ComponentMBeanImpl - Starting component: servicemix-jms INFO - ComponentMBeanImpl - Starting component: servicemix-camel INFO - tutorial - Exchange[Message: Hello World!] INFO - tutorial - Exchange[Message: Hello World!] INFO - tutorial - Exchange[Message: Hello World!] . . . My problem occurs when I redploy this SA. I would like to think that in a production environment, we can redoply SAs without stopping service mix. Hence the '-DforceUpdate=true' variable. An exception is thrown stating that 'A kernel is already registered with the name servicemix-camel/tutorial-camel-su'. Can someone please inform me of what I'm doing wrong or how to resolve this issue? Any advice would be much appreciated. Below is a trace of the service mix log after redeploying the SA again. tutorial-camel-sa]# mvn jbi:projectDeploy -DforceUpdate=true ServiceMixLog on a Redeploy: --------------------------- INFO -
