RepositoryAdmin Filters and Capabilities
Hi,
I would like to use a custom capability defined in my repository.xml and a
filter to match only the bundles matching these capabilities.
I joined the extract of my repository.xml corresponding to the bundle
description, the entry is generated with the maven-bundle-plugin and a
custom obr.xml to add my custom property.
And here is the code portion I use to get the resource corresponding to my
bundle.
final String filter = "(sensortype=thermometer)";
Resolver resolver = repositoryAdmin.resolver();
Resource[] resources = repositoryAdmin.discoverResources(filter);
Unfortunately this doesn't work, and I'm not if it comes from the way I use
my custom capability and the filter or if there is another problem
elsewhere.
Could anyone tell me if the way of doing this is right, or point me to doc
explaining how to do it ?
Thanks in advance.

Thank you for this answer.
I will try to work around this for now, and hope the finalized API suits my
needs at the end :)

This part of the API wasn't thought out very well originally. The
RepositoryAdmin.discoverResources(String filter) method only filters
according to the attributes of the Resource itself, not against the
attributes of its Capabilities.
I believe the
org.apache.felix.bundlerepository.RepositoryAdmin.discoverResources(Requirement[])
method does what you want, i.e., it queries against the resource's
capabilities.
There is ongoing work on the OBR spec inside the OSGi Alliance, so
hopefully we'll actually have a finalized API before the end of time.
