Re: [equinox-dev] Re: equinox-dev Digest, Vol 26, Issue 26


One clarification, Equinox is the reference implementation for *parts* of the OSGi spec.  The framework and various services.

[equinox-dev] Re: equinox-dev Digest, Vol 26, Issue 26






Cameron,

  Another plus for Equinox is that it's considered to be the  
reference (R4) implementation of the OSGi specification.  Looking  
back through this mail-list or the newsgroup will give you a good  
idea of the large magnitude of people banging on it.  Since Richard  
mentioned Felix, I feel less guilty about a small plug for  
Concierge.  It's a R3 implementation that is considerably smaller and  
simpler, and now includes some PDE-like tooling to boot:  http://
concierge.sourceforge.net/.

Best of luck
-ken
