Sharing the jar files across all the application

[Mahammad Nasir <ma...@huawei.com>]

Hi,
 
I have 5-6 non osgi jar files (Not budle). And i have many application
bundles which uses this jar file. I want to know what is the best way to
share these jar files acros all the applications.
 
I can think of,
 
1) collect all the jar files and make this one bundle and load this in osgi
and other applications can now access it. (But, for some reason i dont want
to do this)
2) add the jars to class path of all the bundle. Problem with this is if a
jar files is changed. i have to modify all the application and manifest.
 
 
Is there any other better way of doing this? does osgi allow 2 dofferent
version of non-osgi jar files to load by two diffrent application?
 
 
Thanks Nasir

What do you want to share for those jars? If it's just resource files,
you may put at a shared location for all bundles to access. You should
use bundle if mainly for class sharing, that what OSGi about.

You can also have your own class loader and expose as service for your
OSGi environment to access the jar file as a workaround.

Can you tell me what could be the problems if i dont make it as a bundle?

Currently i am using the second method which is working fine, i am not able to anticipate the problem now. 

I can think of 3 method,

Make the jars available to classloader of osgi launcher. (I am launching felix programatically/embedding felix). Then make the boot delegation true.

Can any one tell me which is the better way of doing this and why? is there any other ways?

You should make bundles out of these JAR files. Otherwise, you are just
fighting OSGi.
