Description

I was following this documentation http://camel.apache.org/karaf.html in order to make Camel work in Karaf.

Many tutorials point to this configuration:

@Override
public void start(final BundleContext bundleContext) throws Exception {
  camelContext = new OsgiDefaultCamelContext(bundleContext);
  registrationCamelContext = bundleContext.registerService(CamelContext.class, camelContext, null);
  camelContext.start();
}

Unfortunately, when I install Camel in karaf:

karaf@root> feature:repo-add camel 2.23.1

only camel-core can be installed, while camel-core-osgi is missing.

Unfortunately camel-core contains only 

DefaultCamelContext

which causes classpath problems in Karaf. For example I import camel-http4, but I get:

Caused by: org.apache.camel.ResolveEndpointFailedException: Failed to resolve endpoint: http4://my.site due to: No component found with scheme: http4

or I import camel-jackson, but I get:

Caused by: java.lang.IllegalArgumentException: Data format 'json-jackson' could not be created. Ensure that the data format is valid and the associated Camel component is present on the classpath

The solution is to use:

OsgiDefaultCamelContext

which is located in camel-core-osgi, which is unavailable in Camel Karaf repo.
