POOSGi modules/bundles granularity

Body
copied!<p>When I first started looking at OSGi I was under the impression that you could just build a JAR and as-long as it had a manifest file, you could deploy it in a OSGi container. I imagined building my modules in a classic way (maven), and maybe use some plugin or something of the sort to write the manifest, I could then have my module that would basically be a standalone application communicating with other modules through OSGi.</p> <p>Further reading about OSGi, I'm beginning to see more examples of it being used at a more low-level and basically replacing dependency injection and providing cross-cutting concern services like logging. And seems that using things like hibernate or others, is a problem... (or maybe I'm just missing something).</p> <p>At least for me, I don't really see the point of having a such fine-gained level of modularity and integration to OSGi, I would much rather have a separate modules, each one of them having its own set of technologies and frameworks, and possibly a web resources and persistence layer. Is this achievable with OSGi? If yes, can you point me in the right direction, examples etc.?</p> <p><strong>edit</strong>, added some more details of how I'm trying to use OSGi:</p> <p>I'm just envisioning the possibility of having a more than one-class module, that might have a more higher-level responsibility.</p> <p>Like say agenda module. In this case I want to have things like, persistence of the events, add events, list events with filters, etc... This agenda might have several internal classes, and might even need a persistence layer. So I would like to use something like Guice to DI those classes, and some JPA to persist my data. </p> <p>I can understand that some X-cutting concerns like server or logging can have a bundle, but the data model is specific to the agenda bundle. So I think my question was at the end What is and what is not possible to do inside a bundle? And what should and shouldn't be done inside as a general practice?</p> <p>Thanks! Mauricio</p>
