Sorry, that should say, "...the OSGi R4.2 specification OR the OSGi JavaDoc..."


Thanks for your reply. Correct me if I'm wrong, but I don't think the OSGi reference will have JavaDocs for the Felix Object, which is what I was looking for.

http://www.osgi.org/javadoc/r4v42/

if you are interested in learning about OSGi or various other tutorials, etc. available on the web. If you haven't already done so, you should also read:

   
http://felix.apache.org/site/apache-felix-framework-launching-and-embedding.html

As the above page explains, Felix implements the OSGi standard Framework interface, which is why you'll want to read the OSGi JavaDoc. I guess we could generate the OSGi JavaDoc and make it available on our site somewhere, but I'm pretty sure someone else has put it online already.

This was the first thing I read, but it didn't seem to deal with the Felix/Non-Felix (or OSGi/non-OSGi) case, so I started looking at the presentations which were more helpful. I'll look this over again.

thanks,

Hey all,

I have a large and complex Java app (call it the main app) that would like to use features from another large and complex Java app (call it the library app). The main app is a standard app written without knowledge of OSGi and the library app is OSGi-based. I have read some of the slideshows and tutorials and so on that you have online, and my impression is that there are some facilities for this. For example, http://felix.apache.org/site/presentations.data/felix-apachecon-20071114.pdf gives this bit of code:

// Define configuration properties
Map configMap = new StringMap(false);
configMap.put(..., ...);
...
// Create application activators
List list = new ArrayList();
list.add(new Activator());
try {
   // Create a framework instance
   Felix felix = new Felix(configMap, list);
   // Start framework instance
   felix.start();
   ...
   // Stop framework instance
   felix.stop();
} catch (Exception ex) { ... }

Ordinarily, my next step would be to look at the Javadocs for the Felix object to figure out what this all means. But I can't find the Javadocs for this project. I've looked through the site, I've googled, I've searched the mailing list a bit (hard to search, eg, by date), and I've downloaded the framework and run maven to the best of my knowledge (I'm not exactly a maven maven). Still no love. Am I missing something obvious? Can someone point me in the right direction?

More generally, other than possible code rework in my library app, what would be involved in larger task of using features that exist in an OSGi app in a non-OSGi app?

Thanks for your help,

   bjorn
