I've lots of doubts in equinox and OSGI versions. It would be very helpful if anyone could help me to understand this.
1) Is OSGI version and Eclipse Equinox Versions are different? (I think Yes) 2) If I'm running some project which uses the equinox container, then how to find which version of equinox container that project is using?
MO: I tried 'ss' command in osgi console in eclipse in the running project, it shows different types of jars org.eclipse.equinox.common.3.6v, org.eclipse.equinox.jetty.1.6v etc etc. Does that mean that the version of eclipse equinox is 3.6 which is appended behind common jar? OR Is that like, Equinox comes with eclipse and it's version is totally dependent on Eclipse Version. Say Equinox 4.5 is a bundle which comes with jars like commons, jetty, registry which has their own version? Confirm?
3) What is equinox container? How can we run an application in equinox container.
OSGi is a specification, and Equinox is an implementation of this specification, like Felix or Knopflerfish.
The version of Equinox doesn't match the version of the specification. The current version of equinox if 3.10, which implements osgi r6 (afaik).
You can see which version of OSGi implementation you are using by looking at the bundle with the id "0". It's the system bundle which export the JRE and the OSGi API. In Equinox, you can use the command b 0 or headers 0 :
In Karaf, the command headers 0 output something like this :
OSGi System Bundle (0)
