<p>Unfortunately there are still some pretty big open questions. So I am not totally sure how this was supposed to tie in with Hibernate's service registry building; not sure what Martin had planned there exactly if he had an clear cut plan for those specifics. Anyway, here I will quote the discussions he and I had about the proof-of-concept...</p>
<p>From Martin:</p>
<blockquote>
<p>I have created a first version of a classloader which should be registered<br/>
for all the "interested" bundles. So there would be x classloaders: One<br/>
for each interested bundle (a OsgiBundleClassLoaderServiceImpl) and one<br/>
"super" classloader (OsgiClassLoaderServiceImpl) which encapsulate the<br/>
Bundle-Classloaders and is responsible for the dynamic part (react on<br/>
bundles and services when they come and go).<br/>
The "super classloader" can then registered with hibernate to help with<br/>
classloading.</p>
<p>...</p>
<p>Next step is to create the BundleActivator which initiates the<br/>
scanning,etc. and is responsible for registering/unregistering<br/>
services/bundles with hibernate. I will start with: I am interested in<br/>
services which implement org.hibernate.service.Service to show my intended<br/>
direction.</p></blockquote>
<p>To which I replied:</p>
<blockquote>
<p>Couple of observations:</p>
<p>1) This notion of bundles "going away" (HibernateBundleActivator.serviceChanged -> OsgiClassLoaderService.unregisterBundle) is really going to end up having bad consequences in reality if that thing going away is used by Hibernate. Think we might want to be a little more proactive in warning about that.<br/>
2) Its not really just org.hibernate.service.Service that we want HibernateBundleActivator watching for. Not sure if that was just a quick swab. It is much more than that. We can talk about those specifics as we move forward.<br/>
3) Not understanding why there is both OsgiClassLoaderServiceImpl and OsgiBundleClassLoaderServiceImpl.<br/>
4) How are you expecting that which ever ClassLoaderService impl above is "real" gets registered to the Hibernate BootstrapServiceRegistry?</p>
<p>Other than these I think I see what you are doing here. The big questions I guess are (a) how the ClassLoaderService impl gets hooked in to BootstrapServiceRegistry and (b) what we actually look for in the bundles.</p></blockquote>
<p>This is basically where we last heard from Martin. He did respond that he agreed about the problems of bundles going away; essentially we will just have to be as proactive as we can be to warn users when this happens. But the 2 big questions at the end of my response were never addressed. So not exactly sure where to go with that.</p></div>
