Hi All, I've been banging my head against the wall now for a week, trying to get a camel route going which consumes a remote service on an EJB2 container in weblogic 10.3. I keep getting class versioning issues between my client and the server.I have the exact same versions of the server jars in karaf as bundles and I import them through my manifest. My bundle installs ok into karaf with a state of "Active" and the camel routes start up. I'm a newbie in the osgi, camel world.
I'm running camel 2.19.1 in apache karaf 4.1.1. My blueprint looks like this: <blueprint xmlns="http://www.osgi.org/xmlns/blueprint/v1.0.0"; xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance"; xmlns:cm="http://aries.apache.org/blueprint/xmlns/blueprint-cm/v1.0.0";
