I get the same failure as miseo. Apparently, m2.safehous.org is offline. I have been unable to reach it when trying this that last two days.

Uh-oh. Thanks for pointing that out. I don’t know what changed. Perhaps my Maven project’s library dependencies versions were not specified strict enough, and now it’s picking up a different version of some upstream dependency than what I had originally tested it with.

At the time I did this project, those jars did not contain the metadata that turns a jar into an OSGI bundle (later versions of the same jars might now contain the OSGI metadata in the manifest file).

Hello,

Thank you for your great tutorial, I am a newbie in OSGI and it helps a lot to understand how to structure a project with OSGI.

However, I am not sure to understand why you are re-packaging hibernate-classes, jta and hqldb. Does the normal way to do is to install jar directly in osgi shell? I have the feeling that you need to do that because hibernate jar are not correctly build to run directly in osgi, am I right?

Do you know if there is another way to do it?

Thanks in advance

Miguel,

I think it should be possible to use this example as a starting point. I’m afraid getting this dynamic behavior to work is ridiculously complex (not simple!), so if you build on top of this example I would make only very minor changes between running a full test suite and checking in the changes.

The version of Hibernate I used is a little dated now, and there may be other persistence frameworks that are better suited for OSGi type development.

Hello loedolff,
Your work here is very interesting. I’m working on a project being developed over Eclipse PDE and we would like to get Hibernate (with this dynamic behavior) as an OSGi service. Is there a simple way to achieve this from your code?
Thanks!

Amit,

I think you are right. The big problem was (as I remember it from almost 2 years ago), to share the same DynamicConfiguration among bundles (all DynamicSessionFactory instances refer to the same instance of DynamicConfiguration). Looking at it again now it seems that the code could just as well have referenced a single DynamicSessionFactory instance. At the moment I cannot see why that wouldn’t work.
