Re: [equinox-dev] Is there a way to capture BundleExceptions?

I also tried creating a FrameworkLog and returning it using an AdaptorHook as well, but no log entries are passed to it by the framework. I think this one is really just mean to be used by my own adaptor hook and will not receive log entries from other parts of the framework.

Thank you for your reply!

I have tried it, but I don't get FrameworkEvents for bundles not resolved due to missing constraints. To unsure I was registering the listener as soon as possible I created an AdaptorHook and registered the listener on the system bundle context within the startFramework method. I got one BundleException due to missing classpath entry for one of the bundles:
org.osgi.framework.BundleException: The bundle class path entry "runtime_registry_compatibility.jar" could not be found for the bundle "reference:file:/D:/eclipse/plugins/org.eclipse.equinox.registry_3.5.0.v20100503.jar"

...but for all non-resolved bundles there were not events raised.

I saw for example in Equinox's log entries like:

!MESSAGE Bundle reference:file:/D:/Scitec/automation/old tests/Target Platform/Third Party Plugins/plugins/org.hibernate_3.3.0.jar was not resolved.
!SUBENTRY 2 org.hibernate 2 0 2010-08-16 11:36:28.475
!MESSAGE Missing required bundle antlr_2.7.6.

Which I caused on purpose by removing bundle antlr_2.7.6 to test this error listening mechanisms. For this and other problems there were no framework events generated.

Any other ideas? I'll keep trying and will let you know if I find the answer, but at this point I'm running out of ideas where to look at.

Thank you!

 I was able to capture one BundleException

Hi Eduardo,

have you looked into OSGi's own asynchronous FrameworkEventListener? If
you solely need to capture the BundleException, you should get it by
invoking FrameworkEvent.getThrowable() on ERROR events (yet, I haven't
tried it myself :) ).
