Hi,
I'm going to ask a silly question but I've just seen someone well known in the OSGi industry say on StackOverflow that the Eclipse Gemini project stopped for some reason.
I saw this after designing a big applications with Eclipse Gemini Blueprint.
During my first research, I started with Spring DM and I then understood the project moved to the Eclipse Fundation.
Is Eclipse Gemini Blueprint still active?
Also, some people push toward using Declarative Services? What's the difference between Bluepring and Declarative Services?
Thanks,
Mickael

I can't paste the link in this reply (I get the following message "You can only use links to eclipse.org sites while you have fewer than 5 messages."...).
The title of the post on StackOverflow is "How to mix Spring and blueprint in OSGi container?".
I may misunderstand what it is said there so I quote the relevant part:
Quote:Actually Spring DM was renamed Gemini Blueprint, and is still the RI (Reference Implementation) for the Blueprint specification. However Gemini is essentially abandonware now since VMware stopped working on it and left the OSGi Alliance.

Hi,
I'm also wondering about the state of the Gemini project. We created a product based on Gemini Blueprint and Gemini JPA. Additionally most of the clients for our products are either based on Eclipse RCP or RAP. With some concern we are observing the following problems/trends in the Gemini/Eclipse and more general the OSGi world:
- The Gemini projects are looking for new project leaders in the community while former leaders with close ties to the OSGi foundation are stepping back.
- P2 is the quasi standard to distribute bundles in the Eclipse world but it is hard to find the resources you are looking for. There is no central repository as with Maven. Some bundles are available on Maven, some on a P2 repo somewhere and some others can be downloaded from Eclipse websites (remembering me to my early days...). No one seems to care about the overall structure and reputation of Eclipse and Gemini projects.
- The Spring bundle repository, a good source for bundles, is already frozen and will be shut down.
- Projects like Spring don't publish their libraries as OSGi bundles any more.
- JBoss removed their OSGi container from its commercial version
I'm wondering what the future of Gemini and OSGi will be.
Regards Sebp

Hello Mickael,
I will take a stab at answering here.

Yes. Very much so. We are lurking in the shadows and trying to balance work/family with commitment to open source software but we are still here I am currently working towards moving Blueprint to OSGi R4.3 support and 2.0 M3 release.
All of the Gemini projects are very mature and stable. Many of those projects implement OSGi specifications that have not changed in few iterations. There aren't many bugs or many new features that can be added to drastically push them forward. That makes forums fairly quiet and releases are not coming out with speed of other projects.

See here -> http://wiki.osgi.org/wiki/Blueprint#Differences_with_Declarative_Services
Main difference is that Blueprint is based on Spring Framework and was created to simplify transition of developers familiar with Spring to OSGi. DS is a bit older and a bit lighter in weight but does not come with tools provided by Spring.
Kind Regards,
Dmitry
