service bundle restart

[Beta User]

Hi, I'm testing s2ap and osgi for web development.
I've got two bundles, one for DAO (which exports service) and for web
(which uses the service).

But one problem is that after DAO bundle is restarted, web can not
access the service which that bundle exports with
IllegalStateException : Bundle 'DAO' has been uninstalled.

after restart web bundle either, then web bundle can access the
service again.
but this is not what I want. I want for web bundle to reconnect to the
DAO bundle's service without refreshing it.

How can I work around this problem?

Thanks in advance.

Hello,
How are you connecting the two bundles ? using Import-Package and a instantiating a concrete implementation of DAO ?

Anyway, you should do this using the OSGi Services: export your DAOs from the dAO bundle using spring DM, and import them in the web bundle (again, using Spring DM) and you should get the dynamic behaviour you seek
