Re: Problems setting up Karaf with ActiveMQ and Blueprint
By the way, you have a JMS example in Karaf:
https://github.com/apache/karaf/tree/main/examples/karaf-jms-example
I can add JMS endpoint in Camel example if it would help:

AW: Exporting an instance of a 3rd party library as service
Hello Geoffrey, Arthur Thank you for your support regarding this topic. I would like to sum up my experience here. Objective Is to let client bundles (C) use a preconfigured service of another bundle (S), which is implemented by a third bundle or library (I). In my case this was blueprint bundles I: the jasypt library as OSGI library, S: my base bundle, C: several camel bundles Service was the org.jasypt.encryption.StringEncryptor interface Check Manifest files for S: Import-Package: "org.jasypt.encryption" and all implementation packages needed to Export-Service: org.jasypt.encryption.StringEncryptor C: Import-Package "org.jasypt.encryption" and Import-Service "org.jasypt.encryption.StringEncryptor" I: export all the used packages from above, should be done by implementor or look for a servicemix bundle project variant implementation all bundles: maven use maven-bundle-plugin with * blueprint S: and instantiate the beans behind the interface (PBE config,...) C: and those namespace configuraions you find in the karaf docs Testing My default blueprint test context initiates by default a bean, which is implementing the StringEncryptor interface. So all references are satisfied. AND What happened to me: Karaf and Camel come with different versions of the jasypt library, ensure that you use only one of them for your C bundles. Or in general ensure your I bundle is used by S and C at the same time. Check with the karaf commands You have only one version of bundle I (bundle:list or la) The command "capabilities" shows that your C bundles are connected to the correct S bundle. I achieved that by using the overrides.properties file: mvn:org.apache.servicemix.bundles/org.apache.servicemix.bundles.jasypt/1.9.2_1;range="[1,2)" Perhaps you can control this also by the ; parameter in the import-package.

April 2022 18:18 An: user@karaf.apache.org Betreff: RE: Exporting an instance of a 3rd party library as service Hi Karsten, My encryptor service provider 'bundle' is just a blueprint file installed in the deploy folder whose singular purpose is to export the service/interface as per the various examples online. The consumer bundle manifest does Import-Package "org.jasypt.encryption" and Import-Service "org.jasypt.encryption.StringEncryptor". It's also ok to use multiple blueprint files in a single bundle. The error message you provided shows that you don't have a service providing the org.jasypt.encryption.StringEncryptor interface. Can your 'base' bundle provide this?

In my "consumer" bundle I have the service reference and the property placeholder in different blueprint files, but this should work, at least it works for everything else. Does your base bundle export the jasypt packages or just the service in the Meta-Inf file? And does your consumer bundle import service and package?

AW: Problems setting up Karaf with ActiveMQ and Blueprint
Thanks Karsten,
I will walk through that stuff and hopefully I get things up and running with
that. As I come from the good old Servicemix days, I was wondering as I do not
have to configure any kind of
connection factory in the blueprint world (I mainly use blueprint routes,
rarely in Java). I just use the entpoint as "activemq://queuename" and things
work.
Nevertheless, I will work through the stuff you provided.
Thanks alot,
Heri

Betreff: AW: Problems setting up Karaf with ActiveMQ and Blueprint
Hello Heribert,
You need to configure the server AND the client (camel).
It is not sufficient to configure the server only.
Here:
apache-karaf-4.4.0\examples\karaf-jms-example\karaf-jms-example-command\src\main\java\org\apache\karaf\examples\jms\command\SendCommand.java
Is an example on how to use a AMQ connection factory by hand. The connection
factory is created by some karaf magic/features and cfg files:
apache-karaf-4.4.0\examples\karaf-jms-example\karaf-jms-example-features\src\main\feature\feature.xml
This creates you the conn factory, you could use/reference it in your camel
context.
camel-examples\examples\jms-file\src\main\java\org\apache\camel\example\jmstofile\CamelJmsToFileExample.java
Shows how to connect to a JMS server, first by initializing the Camel
Jms-Component, then the usage in the route.
In blueprint it could be a reference to the connection factory (which was
created by the feature.xml and cfg file) and with that an initialization of the
JMS component bean in your blueprint. Then your route is using the component
(with whatever name you choose).
Bye

Hello Karsten,
thanks for you reply. The default rollout already provides the file
${KARAF_BASE}/etc/org.apache.activemq.server-default.cfg which is also mentioned
in the documentation at
https://activemq.apache.org/osgi-integration.html.
Also, the activemq.xml file is present in the etc directory and looks okay
for me (compared to the one in Servicemix).
Both files are default and I did not touch them.
Walking through e.g.
http://liquid-reality.de/Karaf-Tutorial/05/
leads to the same issue.
Would be great if you could point me to the right direction ...
Cheers,
Heri

Hello Heribert,
You need to use the endpoint or the component parameters to define the broker
(URL, user, pwd,…).
You could configure the AMQ component as bean including the above parameters,
then all “activemq” endpoints in your context use this.
Or you define all the parameters in the endpoint URL.
The camel and karaf examples for AMQ should give a direction.
