OSGI woes

[Markus Joschko <ma...@gmail.com>]

Hi,
maybe someone with a bit more OSGI experience can help me with my current issue.
I currently play around with a custom extension to the
DefaultAccessManager and ACLProvider which works fine when I use it
without OSGI and sling just in combination with jackrabbit.
However when I use it in the sling context it already fails on startup.

I implemented the access manager as a fragment to the
org.apache.sling.jcr.jackrabbit.server bundle.

<Fragment-Host>
 org.apache.sling.jcr.jackrabbit.server
</Fragment-Host>
 <Export-Package>!*</Export-Package>
<Import-Package>!*</Import-Package>

Then I directly set references to the access manager classes in the
repository.xml, omitting the pluggable access manager.

However when I now start sling, I get the following exception:

1.2011 21:54:10.278 *ERROR* [Repository Pinger]
org.apache.sling.jcr.jackrabbit.server startRepository: Uncaught

The AccessControlObserver is needed by one of the classes used in the
new accessmanager.
I don't understand, why it is not available to the server bundle, as
it is contained in the jackrabbit core jar which is embedded into the
server bundle.
Any header I am missing in my fragment?

Thanks,
 Markus
