[news.eclipse.technology.equinox] Re: Use of Service Binder with Equinox

[Neil Bartlett <njbartlett@xxxxxxxxx>]

Ban,

I think you have probably forgotten to import the package 
org.osgi.framework.

ServiceBinder should work under Equinox but IMHO should be considered 
obsolete. It has been superceded by the Declarative Service 
specification found in OSGi Release 4. Also OSCAR has been known as 
Apache Felix for some time now... it looks like you might be working 
with some old documentation.

Regards,
Neil
