OSGI Service + init-method + exception

I have a question on better way to avoid a bundle to start when starting services throw an exception.

I have a bean and a service declare as :

Code:

---

        <bean id="vaultService" class="com.sample.confiance.vault.impl.VaultServiceImpl">
                <property name="halService" ref="halService"/>
        </bean>
     
        <osgi:service id="VaultOsgiService" ref="vaultService"
            interface="com.sample.confiance.vault.VaultService"
            init-method="start"/>

---

When in OSGI a BundleActivator.start() method throw an exception, the bundle refuse to start and come back to resolved state.
If my vaultService.start method throw an exception, bundle start anyway, ans my service is in an inconsistant state. Is there a way, my bundle don't start if start method throw an exception ?

Thanks for your reply

Hi,

the Spring DM/Blueprint extender cannot prevent a bundle from starting by throwing an exception in the BundleListener's bundleChanged method. That means, you might want to look for another way to guarantee a consistent state of your services whatsoever.

Yes, you could attach OsgiBundleApplicationContextListener in you bundle activator, which gets an event about your context state.

Or you could implement BundleContextAware interface in your bean and when you got an exception, just stop your bundle.
