Hello. I'm learning to use OSGi and am using Felix as the container. I have a trivial Maven project that implements a simple service. There are two implementations: One using the old style BundleActivator interface and the other using modern declarative service annotations.
API module: https://github.com/io7m/osgitest-20160801/blob/master/service0-api/src/main/java/com/io7m/service0/api/SpeakerType.java https://github.com/io7m/osgitest-20160801/blob/master/service0-api/pom.xml Old-style BundleActivator-based service: https://github.com/io7m/osgitest-20160801/blob/master/service0-provider-imperative/src/main/java/com/io7m/service0/provider_imperative/Speaker.java https://github.com/io7m/osgitest-20160801/blob/master/service0-provider-imperative/pom.xml New declarative style service: https://github.com/io7m/osgitest-20160801/blob/master/service0-provider-declarative/src/main/java/com/io7m/service0/provider_declarative/Speaker.java https://github.com/io7m/osgitest-20160801/blob/master/service0-provider-declarative/pom.xml The manifest created by compiling the "imperative" module looks correct (the text wrapping is actually present in the manifest): --8<-- Manifest-Version: 1.0 Bnd-LastModified: 1470064469312 Build-Jdk: 1.8.0_92 Built-By: someone Bundle-Activator: com.io7m.service0.provider_imperative.Speaker Bundle-License: http://io7m.com/license/isc.txt Bundle-ManifestVersion: 2 Bundle-Name: service0-provider-imperative Bundle-SymbolicName: com.io7m.experimental.service0-provider-imperative Bundle-Version: 0.1.0 Created-By: Apache Maven Bundle Plugin Export-Package: com.io7m.service0.provider_imperative;uses:="com.io7m.se rvice0.api,org.osgi.framework";version="0.1.0",com.io7m.service0.api;ve rsion="0.1.0" Import-Package: com.io7m.service0.api;version="[0.1,0.2)",org.osgi.frame work;version="[1.8,2)" Require-Capability: osgi.ee;filter:="(&(osgi.ee=JavaSE)(version=1.8))" Tool: Bnd-3.2.0.201605172007 -->8-- When the bundle is installed and started in Felix, I get the expected messages on stdout: g! install service0-provider-imperative/target/service0-provider-imperative-0.1.0.jar Bundle ID: 5 g! start 5 DEBUG: WIRE: [com.io7m.experimental.service0-provider-imperative [5](R5.0)] osgi.wiring.package;(&(osgi.wiring.package=org.osgi.framework)(version>=1.8.0)(!(version>=2.0.0))) -> [org.apache.felix.framework [0](R 0)] DEBUG: WIRE: [com.io7m.experimental.service0-provider-imperative [5](R 5.0)] osgi.ee; (&(osgi.ee=JavaSE)(version=1.8)) -> [org.apache.felix.framework [0](R 0)] Speaker: constructor Speaker: start org.apache.felix.framework.BundleContextImpl@3870e6b0 The manifest created by compiling the "declarative" module looks correct: --8<-- Manifest-Version: 1.0 Bnd-LastModified: 1470064469068 Build-Jdk: 1.8.0_92 Built-By: someone Bundle-License: http://io7m.com/license/isc.txt Bundle-ManifestVersion: 2 Bundle-Name: service0-provider-declarative Bundle-SymbolicName: com.io7m.experimental.service0-provider-declarative Bundle-Version: 0.1.0 Created-By: Apache Maven Bundle Plugin Export-Package: com.io7m.service0.provider_declarative;uses:="com.io7m.s ervice0.api";version="0.1.0",com.io7m.service0.api;version="0.1.0" Import-Package: com.io7m.service0.api;version="[0.1,0.2)" Provide-Capability: osgi.service;objectClass:List<String>="com.io7m.serv ice0.api.SpeakerType" Require-Capability: osgi.ee;filter:="(&(osgi.ee=JavaSE)(version=1.8))" Service-Component: OSGI-INF/com.io7m.service0.provider_declarative.Speak er.xml Tool: Bnd-3.2.0.201605172007 -->8-- The OSGI-INF/com.io7m.service0.provider_declarative.Speaker.xml descriptor inserted into the jar by the Maven plugin looks correct to me: --8<-- <?xml version="1.0" encoding="UTF-8"?> <scr:component xmlns:scr="http://www.osgi.org/xmlns/scr/v1.1.0"; name="com.io7m.service0.provider_declarative.Speaker" activate="onActivate"> <implementation class="com.io7m.service0.provider_declarative.Speaker"/> <service> <provide interface="com.io7m.service0.api.SpeakerType"/> </service> </scr:component> -->8-- However, when installing and starting the bundle, I get nothing: g! install service0-provider-declarative/target/service0-provider-declarative-0.1.0.jar Bundle ID: 5 g! start 5 DEBUG: WIRE: [com.io7m.experimental.service0-provider-declarative [5](R 5.0)] osgi.ee; (&(osgi.ee=JavaSE)(version=1.8)) -> [org.apache.felix.framework [0](R 0)] g! lb START LEVEL 1 ID|State |Level|Name 0|Active | 0|System Bundle (5.4.0)|5.4.0 1|Active | 1|Apache Felix Bundle Repository (2.0.6)|2.0.6 2|Active | 1|Apache Felix Gogo Command (0.16.0)|0.16.0 3|Active | 1|Apache Felix Gogo Runtime (0.16.2)|0.16.2 4|Active | 1|Apache Felix Gogo Shell (0.10.0)|0.10.0 5|Active | 1|service0-provider-declarative (0.1.0)|0.1.0 Am I missing something here?
