JBoss Fuse 6.2 is based on supported version of Karaf 2.4. It's not a direct community version - it's Fuse' version of Karaf 2.4.
It's actually a fundamental component of Fuse and can't be replaced.
But there are many quickstarts/examples that show usage of JPA, for example here: GitHub - FuseByExample/camel-persistence-part2 at jboss-fuse-6.2.
"It's actually a fundamental component of Fuse and can't be replaced." Thanks for your response
Example link provided by you seems to helpful for my concern. I will try it out and let you know if any help requires / get stuck anywhere.
Sure - just ask here.
