What is the use case for running multiple frameworks in the same VM? -----Original Message----- From: [EMAIL PROTECTED] [mailto:[EMAIL PROTECTED] On Behalf Of Thomas Watson Sent: September 5, 2006 3:59 PM To: OSGi Developer Mail List Subject: Re: [osgi-dev] Inserting Properties at runtime This will lead to issues when you run in an environment where there is more than one OSGi framework running in the VM at the same time. In this environment some framework implementations will have instance specific properties for BundleContext properties. I know Equinox does this when running multiple frameworks in the same VM and I think Felix does the same thing. In this case you may not see the system property changes in the BundleContext properties because they only represent the properties for the specific instance of the framework while the System properties represent global properties for the whole VM environment. If you can live with the property being global to the whole VM then you should get the property using the System.getProperty instead of BundleContext.getProperty. Another option would be to request OSGi add a BundleContext.setProperty method. This way we can set the instance specific framework properties in the case where multiple Frameworks are running in the same VM.

I didn't realize that even after startup you can do a System.setProperty() and the Context will pick it up. I'm not sure if this is 100% pure, but it works in my environment (equinox) so that's all I need.

What I'm trying to do is insert one property during my bundle's startup so that other bundles can see it.
