When deploying a Camel route to FuseESB, as FuseESB tries to start up the jar file, it gives the following exception in the log:

Found initial references null for OSGi service (&(language=js)
(objectClass=org.apache.camel.spi.LanguageResolver))

This causes the bundle to enter a grace period for a few minutes, after which it times out and its status moves to failed. Note that I'm not using javascript in the application, but I assume it is loaded as part of loading Camel core.

Details of my setup:

  • Code in question is written using an OSGi blueprint xml file to define the beans.
  • Code is packaged as a jar, as opposed to an OSGi bundle.
  • Code is deployed by being dropped into the deploy directory so it is deployed by the FAB deployer.

I believe I have the relevant Camel features installed.

Output from features:list:

[installed  ] [2.10.0.fuse-71-047] camel-script-javascript camel-2.10.0.fuse-71-047
[installed  ] [2.10.0.fuse-71-047] camel-script            camel-2.10.0.fuse-71-047

I have worked around this by:

  • reverting to a spring xml file to define the beans
  • packaging the code as a bundle, not a jar

I still don't understand why the Blueprint version didn't work, but the question is now less urgent than it was.

With FAB you should declare the dependencies to your Camel components in your pom.xml file, and use scope=provided.
