osgi blueprint catch event update

Question

i want to execute script when my bundle is update, uninstall, or new.

I use actualy destroy-method and init-method but i don't now if my bundle has just "stop" or "remove".

 <bean id="plugin" class="com.toto.OrderPlugin" destroy-method="remove" init-method="install">

for Sample, why i want to catch event When my bundle is update :

1. i want to know old version and new version and execute script in condition if my bundle is uninstall :
2. i want to drop datable if my bundle is new
3. i want to create datable

What is the right way to do this type of process? Can you give me an example?

Thank

Well in that case I'd go for a std. Activator. Skip using the blueprint xml and use a Bundle-Activator instead, this way you have full control about your bundle start behaviour.
