Iam not sure what else you are looking for. Note that this is a dated post and now you must have easier ways of doing the same - using Spring OSGi or alike solutions. Regu Vikash,

Using reference from serverside.com and javaworld.com I have created a hello world kind of plugin. I have exported it as deployable plugin and fragments.....Now I want to use this plugin for a test application....please send me some URL for reference as I tried searching but could not get one or some help on it. Thanks and Regards, Vikash Anand. Hi,

You are definitely doing the community a favour by writing the tutorial. I shall take a look and get back to you in due course. Regu Hi Oleg,

Recently, I've written a "Getting Started" tutorial which I plan to expend (with community suggestions). http://springosgi.googlepages.com/ But in its current state it already addresses some of the concerns you currently have: - Ability to load all the required OSGi bundles *before* I could load my bundle - Look up a published service from the bundle I deployed and invoke it from my standalone code Although in its current state it mainly concentrates on how to develop and work with Spring-DM using Eclipse, the same principles could be applied on standalone environment. Section 1.4 give a few pointers on the order of the bundle startup The last section is about developing Spring-MVC application which will access the "sample service" deployed earlier as and outside service. And although these are both Spring-DM bundles, the communication between them is pure OSGi. Let me know if you have any comments Cheers Hi Regu

I could see its immediate application in a project where we need incremental download of binaries to address bandwidth issues. Other than that I am unable to get myself to justify the effort that goes into breaking up an application into many dynamic components - I'll not even mention packaging, which is not an easy task today. I guess that explains why I haven't formed opinions on OSGi and its relevance to the different audience you mention above. I however agree that it must make sense to each of the above in order to make an impact. For now, it is definitely an area to watch closely from a technical person's(developer, lead) perspective and of course to try using it to address some of one's own immediate needs - thats the way I view any new technology.

It would be great if you can explain the technical/business benefits of OSGI to different stake holders. 1. Developers (In terms of code) 2. Project Managers (In terms of productivity maintainence) 3. Business Executives (In terms of $) finally 4. What will happen to our lives if we don't understand/use OSGi. what we will miss? in am manner you explained ESB myth. I see OSGI literature out there explains how OSgi helps to solve deployment (effecient class loading, versioning), this definately doesn't match the current hype. I also guess this is not another EJB stuff (Forcing people to un-necessarily thining about distrubution, transaction etc... with hell lot of interface, OSGi API looks similar btw :)) as Rod Johnosn (Spring author) predicted OSGi to be hot in 2008 & investing huge time along app server vendors (IBM & BEA) Anyway it's really nice to read your informative blogs.
