Improve Configuration's update result reporting

Currently, Configuration’s update() method returns a boolean whether the update was successful or not. I feel there is some room for improvement here, for this method (or a relevant sibling method) to return more details about the update. Namely:

• message/reason for the update failing (if any)
• whether (or how many?) jars were actually updated, or there was nothing newer to get
• what is the current version of the business application jar (The one defined in Maven’s <version /> In the business app I can get it by getClass().getPackage().getImplementationVersion())

That way updates could be logged and various feedback could be provided based on the update wizard (i.e. a popup displaying that a new version is now running, possibly linking to a change log).

I’m considering actually returning a report object instead of boolean for the next release. What information do your think should it contain?

[mordechaim]

is that something I need to use for this purpose?

Yes, because the default handler isn’t configured to pass you that info. Unless if you want you can change the injected method call to:

@PostInject
private void getHandler(DefaultUpdateHandler handler) {
}

And then use reflection to get the context field; I’d recommend you against this approach though.

How do I call the update with both the update handler and the injectable

I assume you try to use the update overload that takes an UpdateHandler? In that case you can’t use injectable but you can still get all those info by directly reading that information from the instance itself.

Injectable can be used when the handler gets loaded by the service mechanism or by listing it in the config under <provider updateHandler=com.MyClass />

Perhaps tell me your general setup of the bootstrap so I can try to help.
