RE: [equinox-dev] DefaultAdaptor?


John,

From the one liner you gave to describe what you are trying to achieve, it seems that using  a framework adaptor is not right.
It seems that you should be able to do what you want with a regular bundle and the typical events.

RE: [equinox-dev] DefaultAdaptor?





I looked at what you have here and it looks very nice.  Our basic true requirement is to be able to start our OSGi IP bundle when the framework starts so that it can install our other bundles and then pass control to our bundle manager.  It seems like a fairly simply “AdaptorHook” should be able to do the trick for us here.
 
One question:
 
The “hookconfigurators.properties” that is in the base osgi jar file seems to have a lot of Eclipse specific stuff in it:
 
 org.eclipse.core.runtime.internal.adaptor.EclipseStorageHook,\
 org.eclipse.core.runtime.internal.adaptor.EclipseLogHook,\
 org.eclipse.core.runtime.internal.adaptor.EclipseErrorHandler,\
 org.eclipse.core.runtime.internal.adaptor.EclipseAdaptorHook,\
 org.eclipse.core.runtime.internal.adaptor.EclipseClassLoadingHook,\
 org.eclipse.core.runtime.internal.adaptor.EclipseLazyStarter,\
 org.eclipse.core.runtime.internal.stats.StatsManager,\
 org.eclipse.osgi.internal.verifier.SignedBundleHook
 
Do I need to “exlude” these things if I don’t want their behavior (in particular, something somewhere makes the system bundle offeI dr a lot of services that I do not particularly want)?  Will the resulting framework work properly if I do take them away?
 
Anyway, I love this hook mechanism (in theory, I haven’t tried it yet, that’ll be my job today) and can’t wait to see it properly documented and supported (Equinox 3.3?)

Re: [equinox-dev] DefaultAdaptor?

 

Hi John,


We have removed the DefaultAdaptor in M5 bug https://bugs.eclipse.org/bugs/show_bug.cgi?id=114968.  


We are hoping to get a webpage, probably in the form of a WIKI to help document the adaptor hooks.  For now I would recommend you look at the javadoc from the following packages in the org.eclipse.osgi project


org.eclipse.osgi.baseadaptor

org.eclipse.osgi.baseadaptor.bundlefile

org.eclipse.osgi.baseadaptor.hooks

org.eclipse.osgi.baseadaptor.loader


I remember a post from you a while ago that stated you were extending the DefaultAdaptor.  What is the reason you are doing this?  Can you take a look at the new hooks and see if your needs can be implemented by a hook.  If you cannot please open a bug requesting the necessary hook you need.  I hope to have a WIKI started soon, but I'm currently focused on EclipseCon and M6 so it may be a week or two before I can get one ready.


Tom

[equinox-dev] DefaultAdaptor?

 


   





So, we *were* using the “org.eclipse.osgi.framework.internal.defaultadaptor.DefaultAdaptor” class in order to boot our version of Equinox.  A while ago (we don’t refresh very often) this class could be found in the “framework org.eclipse.osgi_3.2.0.jar” file.  This appears to no longer be true.  That’s ok, we can depend on one or two more jar files.  But I can’t for the life of me figure out where it has moved to.  I hear talk of the mysterious “startup.jar” but cannot seem to find the binary distribution of said JAR from the equinox nightly build pages.  Is this class still part of the JARs that are released as part of the nightly builds?

 
Furthermore, is there documentation anywhere on the proposed new Adaptor architecture I hear so much about?  We would like to use supported interfaces from Equinox in our project!  But I’ve been looking around on the Equinox web-site and haven’t found any documentation on the adaptors.  Perhaps I am looking in the wrong places?
