Enable/Disable Bundles

[mahesh_yamsani]

Hi,

Is there any mechanism to enable and disable the bundles using java code which uses OSGi Framework API.
Do we have any option to get the current version of bundle from Manifest.Mf using OSGI Framework API

You could use org.osgi.framework.BundleContext to start/stop/etc any bundle and to retrieve the Bundle object with the bundle's metadata. If you use Spring DM you could implement BundleContextAware otherwise you have to write your own BundleActivator storing the BundleContext for later use.

Stop should stop the complete functionality of the bundle, my requirements is like this, I want disable the bundle for some context and enable for some context.
I tried in alternative way using Spring Security based on the url for bundle context, even I want to know will it be possible with OSGi frame work API.

If you need to support multiple "contexts" in a single OSGi framework, then stopping the bundle would not be sufficient. Otherwise it should be sufficient. You could even write a bundle to manage your other bundles based on context.

@Glyn, in your post you mentioned You could even write a bundle to manage your other bundles based on context. . That means can we have any functionality like disabling the Bundle (still it should be active on Server).

Scenario where I want this is, Suppose we have two modules (bundles), we want to give access to only one for some users and two modules to other users and there is only one server

[Glyn Normington]

It sounds like you should programmatically decide whether to invoke a service provided by the "disabled" (but active) bundle. Your code should keep track of this "disabled" state as this is not something OSGi or dm Server provides, especially since it seems to be a state which varies depending on the user.

@Glyn, Thank your for early replies. Then I will try tracking them from code itself

When I am calling Stop method for my bundle it is stopping the bundle service and Unbounds this bundle from its Host bundle (my bundle was a Slice), when I am starting the bundle(slice) it is showing the state as START (32), but it is not showing the message like Slice bound to path , does this STSRT and STOP has the support for Slices also......

That sounds like a bug to me. dm Server and Slices should react to the start and stop events that are produced when you call start() and stop() and should unbind and rebind the Slices accordingly, and produce the appropriate messages. Can you please open a JIRA (https://issuetracker.springsource.com/secure/CreateIssue!default.jspa) for this?
