Re: Problem when exporting system packages from Android to bundles
This could have something to do with the way you instantiate your framework, _or_ with the way your bundle is packaged. Could you post (a) your framework instantiation code, and (b) the manifest of your bundle?

Re: Problem when exporting system packages from Android to bundles
Right. I'm not entirely sure what's up, but some things come to mind, - in stead of building the manifest by hand, you should consider using something like BND (perhaps with BNDTools, if you're an Eclipse user) to handle that for you. If you don't need to use DynamicImport, stick with 'regular' imports: that way, the framework can inform you better about what's wrong. - your bundle should have a Bundle-ManifestVersion: 2 to state that it is an R4 bundle (again, BND will do that for you). - your Import-Package statement seems to have a comma after org.osgi.framework . I'm not sure whether that is a copy-paste error, or whether it is actually relevant. (insert-bnd-notice/) - what tools do you use for building your project?

Re: Problem when exporting system packages from Android to bundles
I was considering the use of BNDTools indeed, and will look into that for sure now. I didn't know about the Bundle-ManifestVersion, will look into that too! The comma is indeed a copy-paste error, as you can see in the bottom import statement, I closed the last one without a comma. But, sharp to notice! As far as tools go, I'm just using Eclipse Indigo and the latest Android SDK, dexing and packaging jars with the tools (dx and aapt) from the SDK. When opening the bundle jarfile, the API isn't in there, I don't know what happens after installing and starting the bundle on Felix though...I can actually install a bundle and print something to the console or use Log.d to show a message in Logcat, so the bundle (without using Android libraries) does seem to be packaged in the right way I guess?

Re: OBR and automatic bundle update
On 4/1/12 12:32, Matias SM wrote: Hi everybody, I'm using OBR to help me resolve bundle deployment. Everything works great and as expected but I'm facing a situation I don't know how to solve. --- Here is my test scenario: I have the following bundles in an OBR repository: * SymbolicName: A | Bundle-Version: 1.0.0.1 | exports: (package: p.a version: 1) * SymbolicName: A | Bundle-Version: 1.0.0.2| exports: (package: p.a version: 1) * SymbolicName: DA | Bundle-Version: 1| depends: (package: p.a version: [1 , 2) ) * SymbolicName: DexA | Bundle-Version: 1| depends: (package: p.a version: [1 , 2) ) and (bundle: A version: [1.0.0.2, 1.0.0.2] ) Then my test runs as follows: g! deploy -s DA == this also deploys A version 1.0.0.2 (I guess because it is the newer bundle that exports pa version 1) g! deploy -s A@1.0.0.1 == this __updates__ the previously deployed A (version 1.0.0.2) First issue, if I run: g!deploy -s A@1.0.0.2 == then OBR executes successfully but A@1.0.0.2 is not installed (since there is an updated version of it already resolved). I know this is the expected behavior, but I would like to be able to deploy A@1.0.0.2 It seems like OBR should probably be performing a refresh after it does an update, so there isn't an older version hanging around. Second (and worse) issue, if I now run: g!refresh == so A@1.0.0.2 is completely uninstalled from the framework And then: g!deploy -s DexA == this deployment __fails__ because A@1.0.0.2 can't be reinstalled in the framework!! Not sure why that would be. Are you seeing some sort of error? --- In the OBR project web page [1] can be read: OBR's deployment algorithm appears simple at first glance, but it is actually somewhat complex due to the nature of deploying independently developed bundles. For example, in an ideal world, if an update for a bundle is made available, then updates for all of the bundles satisfying its dependencies are also made available. Unfortunately, this may not be the case, thus the deployment algorithm might have to install new bundles during an update to satisfy either new dependencies or updated dependencies that can no longer be satisfied by existing local bundles. In response to this type of scenario, ___the OBR deployment algorithm tries to favor updating existing bundles, if possible, as opposed to installing new bundles to satisfy dependencies. I don't fully understand this explanation but I get that the described behavior is as intended. Not sure which part you don't understand. My questions are: 1- Is there a way to force the installation of different bundle versions (instead of the update of older ones) when deploying through OBR? No, I don't think so. 2- What kind of issues may this behavior (installation of different versions) rise? (this is not considering the problem of having a lot of bundles installed) Lots of providers is generally a bad thing since it creates many partitions in the overall class spaces of the bundles, meaning that collaboration among them becomes limited to little islands of bundles that happen to be using the same same providers. Note that while I'm using the shell to run my tests, my intention is to use the OBR API in my code. So the solution may be available only in the API. Sorry the mail got so long but I wanted to state my problem as clear as possible. Thank you for taking the time to read and to answer! Still not clear to me what the actual issue is or the solution, but at a minimum OBR should probably refresh after update. - richard Kind regards [1] http://felix.apache.org/site/apache-felix-osgi-bundle-repository.html#ApacheFelixOSGiBundleRepository-OBRServiceAPI - To unsubscribe, e-mail: users-unsubscr...@felix.apache.org For additional commands, e-mail: users-h...@felix.apache.org - To unsubscribe, e-mail: users-unsubscr...@felix.apache.org For additional commands, e-mail: users-h...@felix.apache.org

[ANN] Java Application Architecture: Modularity Patterns with Examples Using OSGi
Apologies for the blatant advertisement, but want to let you all know that my book, Java Application Architecture: Modularity Patterns with Examples Using OSGi is now available. The book's homepage is http://modularity.kirkk.com. Ironically, the book may not be an ideal fit for those of you already highly proficient with OSGi. It's sweet spot is in helping you articulate the benefits of modularity and designing software applications with a modular architecture in the absence of a good module framework like OSGi. Once folks experience the benefits of modular architecture, their increase in a module framework will hopefully increase too. If you experience this type of adoption hurdle, or know others that do, you may find the book interesting. thanx.

Re: Blocked Thread while shutting down Felix / IPojo
I don't know if that may be your issue but in the book OSGi in action [1] they recommend that if a bundle want to stop itself, it should do so in a different thread. This is to avoid possible deadlocks if as part of the bundle finalization there is any waiting for the calls to finish. You can refer to the book's source code examples [2].

Re: Blocked Thread while shutting down Felix / IPojo
This is not related to FELIX-3393, although it appears related to the Aries Blueprint comment on FELIX-3393, which is also unrelated to FELIX-3393. It appears in both situations the component framework (Aries Blueprint and/or iPOJO) is synchronously dealing with a bundle being stopped while at the same time trying to register a service for that bundle. Since the component framework is holding and/or needs its own internal lock when dealing with the stopped bundle and registering the service, we get into a deadlock situation, since both threads also need the bundle lock too. Perhaps just open an issue against the framework to track this. - richard On 4/2/12 13:46, Gay David (Annecy) wrote: Hi, I'm currently have a problem with Felix and or IPojo.

So, the fact that you told OBR to deploy foo in some previous request has no bearing on subsequent requests other than the fact that it impacts the set of installed bundles from which it starts to perform its operation...but that is no different than if you installed a given bundle manually and didn't use OBR at all.

No, I don't think so. 2- What kind of issues may this behavior (installation of different versions) rise?

Re: OBR and automatic bundle update
Yes, you are using the same path when you try to install the first bundle the second time and this will not work since that path is used as a unique key, which is why it returns the same bundle id as printed in your session since it did not install anything the second time. As I suggest you need to have two different paths. However, this isn't an issue for OBR since it uses an arbitrary location string, so it is always unique when it does an install, which you can't easily do from the shell, like I said before.

Re: OBR and automatic bundle update
Ok, I see. Shouldn't the location string be replaced (with the updated version location) when the bundle is updated? It seems a little confusing.

Re: OBR and automatic bundle update
The location string is a deployer assigned persistent identifier, so it cannot change. Your confusion arises because frameworks use the URL as the default location string for simple installs, but the two are unrelated in reality. Matias SM matias...@yahoo.com.ar wrote: Ok, I see.
