Re: Followup on getting felix scr commands to show up in karaf
I'd like us to re-address this issue with getting scr commands being useful in Karaf. I've tested them on the trunk, and after installing the latest version of SCR on Karaf-trunk, there isn't access to any of the scr commands. I'll be researching this over the weekend, but any pointers you can give me would be helpful. Previously in this thread there was the idea of some sort of bridge being developed that would allow Karaf console usage of the scr commands. Could someone shed more light on what this actually means? Are we talking about creating a new set of scr shell commands and then installing them as part of a felix-scr feature?
