Service component deployment fails into a running Equinox application

Hello Guys,

I have an Equinox OSGi application using Declarative Services with 3 plugins:
-a service interface plugin
-a service provider component
-a service consumer component (cardinality: 0..n, policy: dynamic)

Framework is launched.
id State Bundle
0 ACTIVE org.eclipse.osgi_3.8.0.v20110908-1857
3 ACTIVE osgi.example.service.consumer_1.0.0.qualifier
4 ACTIVE org.eclipse.osgi.services_3.3.0.v20110711-1243
5 ACTIVE org.eclipse.equinox.util_1.0.300.v20110502
6 ACTIVE org.eclipse.equinox.ds_1.3.100.v20110705
10 ACTIVE osgi.example.service_interface_1.0.0.qualifier
11 ACTIVE osgi.example.service.implementation_1.0.0.qualifier

In case the application is launched, the service consumer is triggered.

But in case the service provider is installed and started only after the application has launched, SCR fails to load service implementation class. See exception stack below!

What is the problem with this runtime/post-application deployment of the service component?

Please note:
With Apache Felix and SCR, there is no problem with the runtime deployment at all.

Many thanks, Csaba.

Framework is launched.

Equinox on Android

Hi, I am working on a project called Netserv, in collaboration with Columbia University
http://www.cs.columbia.edu/irt/project/netserv/
This service could be implemented in the peripheral routers in internet and it aims to ease the sharing of several data and applications to end users.
It is now supported by a linux platform and the container part is realized using Equinox bundles.
My work is the porting of Netserv on Android systems, that's why I am interested in integrating Equinox on Android; I followed a guide in http://www.slideshare.net/peterbuck/android-and-osgi-can-they-work-together (2008), that seemed to suit our purpose
and when I try to start the modified Equinox through the script in the emulator (I use Eclipse 3.7 for the Android emulator), I get:

Dalvik VM unable to locate class 'org/eclipse/core/runtime/ adaptor/EclipseStarter'
java.lang.

NoClassDefFoundError: org.eclipse.core.runtime.adaptor.EclipseStarter
    at dalvik.system.NativeStart.main(Native Method)

    at java.lang.ClassLoader.loadClass(ClassLoader.java:573)
    at java.lang.ClassLoader.loadClass(ClassLoader.java:532)
    ... 1 more

The path is right, I checked it several times.
Would it probably be because the version of Android I am using is different (new) from the one in the 2008 when they wrote the patches?
Maybe the classes.dex is not readable by my dalvik? Any suggestions could be helpful!
I thank you in advance for any advice you would give.

Optional bundle resolution on startup

Hi,

does anyone here know how to force Equinox to resolve optional dependencies in bundles when the exporting bundle is available at startup?

I keep running into a situation (OSGi launch configuration in Eclipse) where a bundle A has an optional package dependency on p that is provided by bundle B. A and B are both listed in the initial bundles of the framework configuration (B before A), so they are both installed and available.

However, for some reason A gets resolved with the package P left in <optional, unresolved> state until I manually refresh A from the OSGi console. There must be a way to fix this.

Thanks,

Tim.

Use of jsr14 and Java 7 javac


Our use of jsr14 for some Equinox projects in order to use generics AND
continue support of J2SE 1.4 and J2ME Foundation 1.2 will cause problems
for folks compiling against our jars using the Java 7 javac compiler.  I
have opened https://bugs.eclipse.org/bugs/show_bug.cgi?id=369145 to discuss
not using the jsr14 option anymore.  Please comment in that bug with your
concerns or comments.  The consequence is that the Equinox Framework in
Juno will have a J2SE-1.5 minimum execution environment.

Tom
