How to find out when a plan is successfully started? [message #1747313]

Hi,

Is there any way to programmatically tell when a plan is started? I am wondering if there is any event generated by Virgo when this happens. We need something like this as we need to perform few initialization actions that require all the bundles in the plan are loaded.

If there is no such event, is there any other mechanism that can be used to find out when a plan is started?

We are using Virgo 3.6.2. Any help is greatly appreciated.

Thanks,
Raghu

Bundles in a plan are started in the same order as they are listed.

You can therefore add an extra bundle at the end of the plan and do whatever you want in its activator.

Virgo also fires an event. If I remember correctly Glyn explained some time ago in a post that you can get a virgo service from the osgi registry and register a listener to be notified. I can't find the post now as I am on my mobile....

Following the advice from a previous thread (referred to above), I have implemented the call back (by extending "org.eclipse.virgo.kernel.install.artifact.InstallArtifactLifecycleListenerSupport") and exported it as OSGi service. This did the trick and I can now tap into the life cycle of Plans as well as other artifacts.

However, while compiling my code, I found that Maven central doesn't have the necessary Virgo dependencies for the classes "InstallArtifactLifecycleListenerSupport" and "DeploymentException". They are part of the JARs "org.eclipse.virgo.kernel.deployer_3.6.2.RELEASE.jar" and "org.eclipse.virgo.nano.deployer.api_3.6.2.RELEASE.jar". I had to add them to my Maven repo explicitly in order to make the build succeed.

It would be very helpful if these and perhaps other Virgo artifacts are uploaded to Maven central.

Thanks,
Raghu
