OSGI in Non Spring DM Server

[MC1]

Hi ,

I am very new to OSGI. I have tried to search previous threads and have not quite got the anwser i am looking for. Please forgive any replication.

1) Is it possible to use the Spring Dynamic modules project without using Spring DM Server as a deployment platform? we only have a normal J2ee application server.

2) I am considering embedding osgi in a Spring MVC Web application deployed on a plain Tomcat. The reason for embedding is because i have URLS exposed to other services, i was thinking of hooking into OSGI from my web app. How would i go about doing this? The concept of embedding tomcat inside OSGI doesnt seem like an option to me.

Yes, it's possible, but you must use one of OSGi frameworks (Felix, Equinox, Knopplerfish) to get it work.
Only one J2EE AS can deploy bindles - Glassfish.

It's very important to understand, do you really need OSGi or you can solve your task in common way.

But if you want to use OSGi platform, you could do next things:

Version 1:
1. Build you app as OSGi application.
2. embed web server into OSGi framework.
3. deploy your bundles into OSGi enviromnent and you will get osgi web application.

Version 2:
1. Pack you app as web application.
2. Download karaf or spring dm server.
3. deploy your application as a simple web application.

Version 3 (true way):

All from version 1 + karaf or spring sm server + proper web bundle.
How to do and deploy bundles with web support you could read at "Spring DM Modules Guide".
