Re: [osgi-dev] DS & Concurrency

[Matt Sicker]

Very nice article! I feel that it helped me understand how to properly
understand the dynamics of DS components. I typically refer to the javadocs
when working with OSGi APIs, and they're usually rather terse about things,
so then I end up falling back to tutorial articles which generally don't go
into this level of detail.

Great article Peter.

It's a good summary of "Java Concurrency in Practice" and the examples for 
different DS scenarios are extremely helpfull.

Thanks a lot for sharing

I think having another place to go is imho not helpful. Best is for people to 
link to the OSGi enRoute site so that things are easy findable on Google.

Anyway, it is out of my hands …

Re: [osgi-dev] DS & Concurrency

[Christian Schneider]

Hi Peter,

this is a very helpful article. I learned quite a few new things reading it.
As a pure app note it might be hard to find though.

Generally there are many documentations for DS scattered around enroute.
I wonder if we could combine them to something like a DS reference 
documentation.
How about providing a separate site ds.osgi.org that is all about 
declarative services.
I am really missing such a place. Currently I often search for some 
detail of DS and then have some difficulties finding

it in enroute or some things are even only outside enroute.

Then enroute could concentrate on being the place for examples, concepts 
and best practices.

Hi Peter

I saw it on twitter it is very welcomed article. An initial scan is very 
promising. I will read in full and possibly add some things about locks and 
latches.

I did much of it with bluetooth protocol and they are hopefully correct  :)

Cheers
