Yeah, as said: don't use new, but rather use spring-dm to export BundleBClass as a service (you have to add an interface therefore) and import it into bundleAClass
this looks then something like: bundleBspring <bean id="a" class="XXX" /> <osgi:service interface="..." ref="a" /> bundleAspring <bean id="b" class="YYY" > <!-- via props or autowiring; as u like--> </> <osgi:reference interace="..." id="xyz" /> kind regards, andreas On Tue, Feb 15, 2011 at 06:08:59PM +0100, Marco Firrincieli wrote: > I figured there must be a way to get a service from bundleB and IF that > service needs something (something he owns!) then I thought it could be > perfectly able to get it from its own spring context (that is 'wiring" it to > itself). > > I don't need to actually get the autowired bean from bundleB.
