Tutorial #3 - Camel - Redeploying SA Causes 'kernel already
registered' exception
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.

Re: Tutorial #3 - Camel - Redeploying SA Causes 'kernel already
registered' exception
Posted by aknapp <ak...@godaddy.com>.
Unfortunatley, servicemix 3.3 is causing a lot more problems than the kernel.
I'm not even able to install the SA in the first place.
I downloaded servicemix 3.3 from:
http://people.apache.org/repo/m2-snapshot-repository/org/apache/servicemix/apache-servicemix/3.3-SNAPSHOT/?C=M;O=D
The answer your second response:
"Another deployment option is to copy the SA to the deploy dir, and, to
deploy a new version, just overwrite the file.
"
This causes the same problem in version 3.2.1: "A kernel is already
registered with the name servicemix-camel/tutorial-camel-su"
ServiceMix 3.3 displays a lot of warnings on the start of the service -
example: WARNING: Could not find the configuration file
classpath:META-INF/cxf/cxf.xml on the classpath. This is not the case in
version 3.2.1.
Below is the exception thrown when installing the SA:

Re: Tutorial #3 - Camel - Redeploying SA Causes 'kernel already
registered' exception
Posted by aknapp <ak...@godaddy.com>.
How stable is this release? I'm a little concerned with the fact that the
release that is recommended on the web site is 3.2.1 and it doesn't handle a
simple update of a SA. Is servicmix stable enough for a production
environment?
I will try version 3.3.
I'm assuming since 3.3 is not the recommended release, it's not stable?
Thank you for the input.

Re: Tutorial #3 - Camel - Redeploying SA Causes 'kernel already registered' exception
Posted by Guillaume Nodet <gn...@gmail.com>.
I've already seen this error, but it usually happen when there is a
previous deployment problem.
In this case, I'm not sure what happen exactly, but the problem should
be gone with ServiceMix 3.3 already (because of some internal changes
which got rid of xbean-kernel which is causing this issue).
Could you grab a 3.3-SNAPSHOT distribution and see what it gives when
you repeat the same steps ?
Another deployment option is to copy the SA to the deploy dir, and, to
deploy a new version, just overwrite the file.
