Doh. I completely missed the log command when I was looking at the console commands. That would have come in handy a few days ago. :-/

I have verified that exceptions are logged for BundleActivator start() and Declarative Services activate()/deactivate(), and when parsing malformed activator.xml files. However, BundleActivator stop() does not log and instead the exceptions are sent to stdout. I assume this is a bug I should log?

In answer to your question #2, Declarative Services logs to the LogService in all of those cases. I'm pretty sure that BundleActivator start() and stop() go to LogService as well. Try running with -console and using the "log" console command.

Subject	[equinox-dev] Logging, exceptions, and the UserAdmin service

Hi, I have a few issues that I'm having difficulty finding information on. I would appreciate any assistance or pointers to documentation. 1. Do messages logged with org.eclipse.equinox.log get persisted to disk anywhere, or do you have to have a listener to get them? If a listener is required, what's the best practices way of making sure your listener is running before log messages are generated? 2. Do errors get logged somewhere when a BundleActivator start() or stop() method throws an exception? Also, I'm not seeing any errors when the activate() and deactivate() methods for declarative services throw, or when an activator.xml file is malformed. Instead everything just fails silently. 3. I'm trying to use org.eclipse.equinox.useradmin which requires me to load org.eclipse.equinox.preferences and org.eclipse.equinox.registry. Although all show as active in the console, I can't get a reference to the UserAdmin service which I'm guessing is due to the log messages (see below) generated on start up. What am I missing here?
