Thanks, it is getting clearer to me.
Would you recommend using enRoute for a server application translating rest
requests to CMIS?
Now with these information, it feels like enRoute was built for desktop
standalone apps not for server applications?
Best,

Hi Philip,
For Karaf, you probably have to install the dependency bundles first.
Using enRoute, it creates an "uber" jar embedding all jar files required
for execution. You don't need a container: it's a regular standalone jar
application that you run with java -jar.
Karaf uses a modular approach where your bundles are very light, and you
install dependency bundles in Karaf (that other bundles can use). That's
why we have Karaf Features to install all in a row.
So, if you are interested by Karaf, I can help you to create a Karaf
feature for your application or at least provide the commands you should
do to install the dependency bundles.
Regards
JB

This is working fine. All dependencies are in place and I can start it.
