Newbie: OSGi questions [message #86322]

Hi all,

I am new to OSGi so bare with me J

I have a couple of Questions:

1.. What are the prerequisites for running OSGi bundles?
Does it require the JVM to bootstrap the bundles directly? Or is it
possible to load the OSGi within an existing JVM (in my own main()
function)?
2.. I am developing a web application and running it on a Tomcat 5.5
server
I found the following link:
http://www.eclipse.org/equinox/server/http_in_container.php and couldn't
figure out whether its possible or not to load OSGi bundles under an already
existing web application?
Thanks in advance,

Asaf

The requirement for running OSGi bundles is just an OSGi framework like
Equinox. You can launch Equinox from your own program and no special
bootstrapping is required.

Definitely. That's what the servletbridge does. e.g. launches an instance of
Equinox and uses it to host various servlet and other bundles.

Is there any sample anywhere showing how to launch Equinox OSGi framework in
an embedded mode?
I would like to manage it from a servlet server (TOMCAT 5.5) yet without
using the Bridge.

The best place to start would be to take at the servletbridge's
FrameworkLauncher (e.g.
org.eclipse.equinox.servletbridge.FrameworkLauncher)and in particular how it
interacts with EclipseStarter
