If you don't mind manually maintaining a list of bundles that you want to include in your application (at least to start with), then you may be interested in using org.eclipse.equinox.simpleconfigurator. This small bundles reads a file called configuration/org.eclipse.equinox.simpleconfigurator/bundles.info, and install all the bundles listed into the framework and supports reference.

Hi all, In the config.ini file, all my bundle paths start with "reference:". But only the core ones are loaded like that. Looking at how my other bundles are loaded, I found that this is done by org.apache.felix.fileinstall. I've looked at the documentation of this lib and found no way to make the automatically installed bundle treated as references. I've started to look at the fileinstall code, and it's quite convoluted... so I have trouble to find where to add the "reference:". I'll continue my search tomorrow... The solution to remove my source bundles will be my last resort, I guess. Thanks everybody for your help.

I imagine you already have your own custom launcher, or at least our own "provisioning" bundle that is doing the installs for your. Reference installs are the way to go if your provisioning bundle has a managed storage area where it is downloading and storing the bundle artifacts before actually installing them AND you are happy with the framework using the content from this managed storage area at runtime. This is how the Eclipse platform (with p2) manages the installed bundles in Eclipse (i.e. the bundles are stored in the plugins/ folder) without having duplicates on disk. But if you do not have that kind of provisioning storage area then you should consider Neil's suggestion. Note that if you do not want to use the simple BundleContext.installBundle(String location) method which requires the bundle location to be a proper URL (e.g. reference:file:/path/to/bundle.jar<file:///\\path\to\bundle.jar>), but instead you want to control your location strings to be something else then you can use the installBundle(String location, InputStream content) like this: bc.instsallBundle("mylocation", new URL("reference:file:/path/to/bundle.jar<file:///\\path\to\bundle.jar>").openstream()); Tom [Inactive hide details for Neil Bartlett ---11/19/2013 06:34:30 AM---OSGi persists the state of all installed bundles in the Fra]Neil Bartlett ---11/19/2013 06:34:30 AM---OSGi persists the state of all installed bundles in the Framework storage directory; by default in E From: Neil Bartlett <[email protected]><mailto:[email protected]> To: Equinox development mailing list <[email protected]><mailto:[email protected]>, Patrick Valsecchi <[email protected]><mailto:[email protected]>, Date: 11/19/2013 06:34 AM Subject: Re: [equinox-dev] Can I avoid having all my OSDI containers copied? Sent by: [email protected]<mailto:[email protected]> ________________________________ OSGi persists the state of all installed bundles in the Framework storage directory; by default in Equinox this is 'configuration/org.osgi.eclipse'. Therefore, once the bundles are installed they are no longer needed in the external "plugins" directory. You might want to consider writing a custom OSGi launcher. On first use it could download the bundles from a URL or temporary filesystem. The BundleContext.installBundle() method can read bundles from any InputStream, so local files are not necessarily required. This will cache the bundles into the framework storage dir. Then on subsequent uses the framework will start up with all the same bundles in the same state. Alternatively you could pre-cache the bundles as part of the install process before shipping the device to users. This has the advantage that Equinox will persist the resolution state, which may improve start-up time.

The biggest directories are the plugins and configuration/org.eclipse.osgi/bundlesdirectories. The plugins directory is where all my bundles are, so I'm OK with it. But theconfiguration/org.eclipse.osgi/bundles directory seems to contain mostly copies of my bundles. For example configuration/org.eclipse.osgi/bundles/117/1/bundlefile is an exact copy ofplugins/org.opendaylight.controller.clustering.services-implementation-0.4.0.jar. That is a big waste of disk space. I've tried to find a configuration option to disable that and found nothing. Is there something? I've looked at the Equinox source code as well and didn't find anything. Can somebody point me to the location in the code where this is done? I'd like to disable that or at least replace it by a hard link.
