Re: [equinox-dev] Adding to the framework exported libraries?

[BJ Hargrave <hargrave@xxxxxxxxxx>]

Set the system property org.osgi.framework.system.packages to 
"com.acme.foo;version=1.0.0" before launching Equinox. Then Equinox will 
export that package from the system bundle and other bundles can wire to 
it. The system bundles is the framework and the framework's classloader 
will be used to provide that package.

[equinox-dev] Adding to the framework exported libraries?






Hi, i'm using EclipseStarter to start and integrate the Equinox OSGi 
Platform in a launching application. I want my launching application to be 
able to expose some services and/or libraries to bundles that run within 
the embedded OSGi environment. However i'm having a hard time figuring out 
how to define this. This may not be conventional, but it would be very 
useful for my application. 

As an example, my launcher loads some configuration data and uses that to 
determine how to launch Equinox, however i want to also expose the 
configuraiton data to my bundles, as a service. As well, the classes that 
i use in the launcher that load the configuration are reusable and i want 
to expose them as an exported library for my bundles to import and use to 
load other configuration data. 

In short, what i would want to do is simply reference the OSGi 
object/context and call something like osgi.export( "com.acme.foo", 
"1.0.0" ). I know that the classes are available because they are in my 
launcher and i have started eclipse with my classloader as the parent, so 
it is just a matter of making the OSGi bundle loader/validation step 
recognize that there are more packages exported then just those that come 
with Equinox itself. 

Does this make any sense? I can try to describe this another way if it 
would help.

Is there any way to do this? I've looked a bit at the framework 
extensions, but they don't seem to provide what i'm looking for, because i 
need to pass to the OSGi platform some information, and let it pick up the 
classes from the parent classloader, rather then giving it a ready bundle 
to use. 

Thanks for your help.
