Why is XOM library missing in Fuse 6.2?

Solution Verified - Updated -


  • Trying to install a bundle, involving Apache Camel framework and using the camel:xmljson directive inside the XML configuration, I encountered the following error:

  • Searching inside all application server’s folders of JBoss Fuse 6.2 I could not find a library containing such a class as nu.xom.Element. It should be there because bundle camel-xmljson is provided directly as a Service Bus’s feature.

  • The project I’ve installed has been simply ported from JBoss Fuse v. 6.0 to v 6.2. In previous version the installation works fine, and the project worked fine. I took a look inside JBoss Fuse 6.0.0 system lib:


    But I couldn't find it in 6.2.0.

  • The feature camel-xmljson is, by default, uninstalled. So it does need to be installed (I did via Karaf Cosole). Do I need to install some other feature in order to make this one correctly working? Or is this a bug of the Service Bus?
