getting OSGI Bundle from Eclipse IConfigurationElement

Question

Hi there,

I am looking for extensions that implement a specific extension point, and am using the following acceptable method to do this:

IExtensionRegistry extensionRegistry = Platform.getExtensionRegistry(); if (extensionRegistry == null) { return TEMPLATES; }

IConfigurationElement[] config = extensionRegistry.getConfigurationElementsFor("com.ibm.im.launchpoint.templates.template");

I then would like to get the version of the defining bundle. I would use the following API, but the API for PluginVersionIdentifier is deprecated:

for (IConfigurationElement e : config) { BlueprintTemplate template = new BlueprintTemplate();

IExtension declaringExtension = e.getDeclaringExtension(); PluginVersionIdentifier versionIdentifier = declaringExtension.getDeclaringPluginDescriptor().getVersionIdentifier();

I could not find an alternative in the new API - i.e. from a IConfigurationElement, how do I get the version id descriptor of the bundle. Obviously, from the Bundle I can get the version using the Bundle.getHeaders(), getting the Bundle-Version value - but how do I get the Bundle in the first place??? Platform.getBundle(bundleId) is not enough since I might have multiple versions of same bundle installed, and I need to know who I am. At the moment I have a chicken & egg situation, and the only solution I have is the above deprecated API.

I suggest browsing a bit the Javadoc deprecation descriptions, the replacement is documented. I found the following code, but did not test it.

String contributor = e.getDeclaringExtension().getContributor().getName();
Bundle bundle = Platform.getBundle(contributor);
Version versionInfo = bundle.getVersion();

Out of curiosity: why do you need to get the version of the extending plug-in? As far as I know, the goal of the extension point mechanism is to detach specific information about the extender, and only the information described in the extension (plugin.xml) or the referenced code is needed.
