I am setting this using sling. If I give a version for javax. How can I configure my bundles so as to use different versions of javax. If you want to use exactly 1. This can be downright difficult due to the OSGI bundle resolution rules.

Check out this article--I found it to be a good explanation of the various rules that apply. Specifically, check out the uses directive: Life will be much simpler if there is a way for both to use the the same version but I know that may not always be possible.

For every Import-Package package declaration, there must be a corresponding Export-Package with the same package. Bundles can also attach other attributes to the packages it imports or exports. What if we added a version attribute to our example:. This means, Bundle A has a dependency on package org. Yes, you read correctly. If there is a higher version for that same package, the higher version will be used.

So bundle A will not resolve correctly unless there is a corresponding bundle B that exports the required package:. Note that the reverse is not true… If Bundle B exported version 1. It can use this import and resolve just fine:. This is because imports declare the versions they need. An exported version does not specify anything an importing bundle must use which holds for any attributes, not just version.

Import-Package dictates exactly what version or attribute it needs, and a corresponding Export-Package with the same attribute must exist. What happens if you have a scenario where Bundle A imports a package and it specifies a version that is provided by two bundles:.

Which one bundle does Bundle A use? The answer is it depends on which bundle B or C was installed first. Bundles installed first are used to satisfy a dependency when multiple packages with the same version are found.

Things can get a little more complicated when hot deploying bundles after some have already been resolved. As we saw from above, the version declaration in Bundle A 1.

However, that brings us to another temporal rule for the bundle resolution: Bundles that have already been resolved have a higher precedence that those not resolved. The reason for this is the OSGI framework tends to favor reusability for a given bundle. The above rules for bundle resolution are still not enough and the wrong class could still be used at runtime resulting in a class-cast exception or similar.

Can you see what could be missing? What if we had this scenario. Bundle A exports a package, org. So far everything is fine as long as there is another bundle that properly exports org. These two bundles will resolve fine. Now, if we install two more bundles, Bundle C and Bundle D that look like this:.

We can see that Bundle C imports a package, org. Bundle C can try to use FooClass from org. Bundle A expects to use version 3. So the classes used are not consistent within bundles at runtime i. What we need is to tell anyone that imports org. Given the new configuration for Bundle A, the bundles would not resolve correctly from above.

Bundle C could not resolve, because it imports org. The solution to this is change the version in Bundle C for org.
