> The camel component just contains the core camel-jars, but some usecases require the use of addon components (for example camel-cxf) which are not present in the core camel-jar. If you have multiple SU's with a dependency on an addon component then you will hit classloading conflicts (ClassCastException typically ). You currently need to:
> 1) Add the camel extension components to a jbi shared library
> 2) Edit the camel components jbi.xml and add your shared library to the components bootstrap classpath as shown in this example:
> http://open.iona.com/issues/secure/attachment/11763/jbi.xml
> Having to edit the jbi.xml is not ideal so this enhancement is to add a placeholder shared library to the camel-core component. The shared library can be empty but will need to exist in the hot deploy directory.
> This would eliminate the need to hack the jbi.xml, you would just need to overwrite the shared library ..
