Where can I find Spring 4 OSGi bundles

Question

Where can I find OSGi bundles for Spring 4? I checked http://ebr.springsource.com/ but can only find Spring 3.2.x and the artifacts in Maven Central are not bundles.

Clarification

I'm not looking for Spring DM or similar. I'm looking for the "Spring Framework" JARs (spring-core, spring-beans, spring-context, …) as OSGi bundles. I'm not trying to create an application context in an OSGi environment. I just need the (exception) classes in an OSGi environment.

Answer 1

Spring will NOT support any further releases as OSGi bundles. The official support has been stopped with spring 3.2.4 (although you could find 3.2.5 artifacts here, contradicting the statement made in the Eclipse Forum)

Glyn Normington from Spring source acknowledged that in several places, see here:

• on Twitter
• Eclipse Forum

However, there is hope. On the Karaf - dev list, one can read that they intend to support spring libraries in the ServiceMix project. Details in the entire thread see here.

Answer 2

I found ServiceMix had provided OSGi-fy Spring bundles up to ver. 4.1.4, http://repo2.maven.org/maven2/org/apache/servicemix/bundles/org.apache.servicemix.bundles.spring-aop/

I tried it in my osgi Bundle project, to set dependeny like that :

 <dependency>
        <groupId>org.apache.servicemix.bundles</groupId>
        <artifactId>org.apache.servicemix.bundles.spring-core</artifactId>
        <version>4.1.1.RELEASE_3</version>
 </dependency>

Run in Felix a found sprint bundles are activated :

START LEVEL 1
 ID|State      |Level|Name
...
5|Resolved   |    1|Apache ServiceMix :: Bundles :: spring-expression (4.1.1.RELEASE_3)
6|Active     |    1|Apache Felix Gogo Command (0.14.0)
7|Active     |    1|Apache Felix Gogo Runtime (0.12.1)
8|Active     |    1|Apache Felix Gogo Shell (0.10.0)
...
10|Active     |    1|Apache ServiceMix :: Bundles :: spring-context (4.1.1.RELEASE_3)
11|Active     |    1|Apache ServiceMix :: Bundles :: spring-core (4.1.1.RELEASE_3)
.... 

But in it's latest release 5.4.0, ServiceMix only include spring 3.2.11.

Is there any risk when use spring 4.1.1 in my OSGi environment?
