Re: Re: Re: Re: Re: Re: Re: Re: Re: OSGi in Web Application

Hi,

Great ur answers made my confusion clear...

This is what I did just tell me if i am correct.

Will use only one bundle and one Web app for my explanation.

1. Bundle1 was registered as a Service.
2. In the Web App i made a ServiceLocator class and using ServiceTracker
found out the Service.
    also made a function to return the found service

3. In the Servlet I called that method which was discovered...

It all worked thanks....

One thing I have doubt is the BundleContext i need to send to my
ServiLocator ... which bundlecontext shud that be?
