Konrad Windszus commented on JCRVLT-195:
----------------------------------------
I am using the HTTP package manager ReST API. The package contains both the
hook in one sub package (as OSGi bundle below one install folder) as well as
the subpackage leveraging the hook. The only problem I see is that just
ordering the packages is not enough here, as even after installing the sub
package with the hook it takes some time until the bundle is finally picked up
by the OSGi installer and correctly started. Only afterwards the hook is really
ready for consumption by others.

> URL: https://issues.apache.org/jira/browse/JCRVLT-195
> Project: Jackrabbit FileVault
> Issue Type: Improvement
> Components: Packaging
> Reporter: Konrad Windszus

>
> FileVault Packages support both internal and external hooks. Internal hooks
> are JARs which are part of the package itself. External hooks are provided
> through some classloader (usually through the Bundle Classloader in an OSGi
> context, https://issues.apache.org/jira/browse/JCRVLT-116). Installing a
> package depending on an external hook class which is not found, leads to an
> error.
> Therefore it would be beneficial to explicitly add a dependency from the
> package referencing an external hook towards the OSGi bundle providing the
> hook. Only that way it can be assured, that the installation of this package
> is deferred until that bundle providing the hook is finally active. Currently
> only package dependencies are supported though, which are not enough, as
> there is a delay until the embedded bundle in a package is deployed as well.
