programmatically add new bundles? [message #480691]

Hello,

in my usecase I have server types where each one is composed of it's own
collection of jars and I would like to be able to start multiple
instances of the same server type simultaneously within Eclipse.
But:
a) I don't want the jars of one server type be visible to other server
types and
b) I cannot guarantee that multiple instances of the same server type
can work together within the same class loader as there might be some
class state involved in one server instance that would influence the
other server instance.

The first thought was to create a bundle per server type. But then I
would need to programmatically add new bundles to start new servers.
E.g. by copying the server type bundle, adding an id to the SymbolicName
attribute, and starting it.
Isn't there a more elegant way of reaching the same goal? An instance of
an OSGi Service doesn't have an own classloader, it lives within a
bundle that is already there right?
Any hints are much appreciated!

Best,

Sandro

I don't know an elegant way Smile

but I was experimenting with a similar approach.

Creating bundles so that different versions of a library could be dynamically loaded into a running instance.

https://bugs.eclipse.org/bugs/show_bug.cgi?id=263723

There is some sample code attached to that bug. I think I was exposing it as a service, but that's not necessary. I think the BundleContext can be used to install the new bundle and the PackageAdmin service can be used to refresh the packages it exports.
