----------------------------------------

Going to work initially on getting the deployement/undeployement of features working through
JMX MBeans and then will hook up the features plugin using a goal to the mbeans.

===========

>From looking into the MBean setup for features.

There is a few things I would like to change in order to get the install working for a full
features descriptor.

Currently - you can really only install/uninstall a feature.

Installing a repository - will only add a repository and add the list of features in that
repository to an available list but you would have to install all features individually.
Some people may want this. but it doesn't actually install everything in a repository.

Plus this is also not recursive so if you install a repository and it has repositories of
its own - these will not be added.

So my proposal is to change the intention of "InstallRepository" to actually going ahead and
install everything in that repository and making it recursive.

Add an operation "AddRepository" which will be recursive but will only add the Repositories
and the features to the list of available features and our Repositories tag will change to
Available Repositories and have a new entry of "Installed Repositories"

Then add two new operations in Repository to install/uninstall a Repository (this will include
installing/uninstalling all features in that repository and again it should be recursive if
there are any sub repositories).

Currently the connection of a feature to a repository is not there so that would be part of
this solution.

Does this seem reasonable to change ?

Edell.

===================

I have got a bit further with getting the install/uninstall to work.

I have changed one of the api's addRepository though.

So now For the FeaturesService - you can install/uninstall a Feature, addRepository, installRepository.

Then depending on whether you have added or installed the repository it means different things.

Added - means that you can add the Repository and a list of the available features will be
added to the Available feature list so you can sort of pick and choose what you want to install
or then go ahead and install the entire repository which will install all dependant repositories
and features.

and abviously installed means to install the entire repository and all its dependants.

So basically adding just gives the user the option to see whats in it before they install
it and if they are sure they can ignore adding and just install directly.

I have one issue left to resolve on the recursion - it seems to have a problem with a feature
depending on a feature.

I end up with a

org.osgi.framework.BundleException (no securityManager: RMI Classloader disabled.
