Try to use osgi compendium services

[hsyn]

Hi everybody,

i try to set up a project using "maven" defining the project. "bundlor" to create the osgi manifest, "Spring extender" to instantiate and get references of services. Virgo as the osgi runtime org.osgi.compendium as the api imported and equinox bundles as implementations of the compendium services !

in mavens pom i defined the api´s i need and defined the scope as provided, because i think they are available in the runtime. (i also provided them into the runtime to be sure they are available)

pom.xml

		<dependency>
			<groupId>org.osgi</groupId>
			<artifactId>org.osgi.core</artifactId>
			<version>4.2.0</version>
			<scope>provided</scope>
		</dependency>
		<dependency>
			<groupId>org.osgi</groupId>
			<artifactId>org.osgi.compendium</artifactId>
			<version>4.2.0</version>
			<scope>provided</scope>
		</dependency>

the manifest file created by the bundlor (only the import) i think this looks right.

manifest.mf

Import-Package: org.osgi.framework,org.osgi.service.cm,org.osgi.servic
e.event,org.osgi.service.log,org.springframework.beans.factory.annotatio
n,org.springframework.core.style,org.springframework.util

the spring extender tries to get an instance of the LogService by interface

bundle-context-osgi.xml

	<reference
		id="logService"
		interface="org.osgi.service.log.LogService" />

to be sure not missing anything i served these jar into the pickup folder of vigor

pickup folder

org.eclipse.equinox.cm_1.0.200.v20100520.jar
org.eclipse.equinox.event_1.2.0.v20100503.jar
org.eclipse.equinox.log_1.2.100.v20100503.jar
org.eclipse.equinox.util_1.0.200.v20100503.jar
org.eclipse.osgi.util_3.2.100.v20100503.jar
org.osgi.compendium-4.2.0.jar
org.osgi.core-4.2.0.jar

and i face to this output and have no clue how to solve this issue.

meanwhile i try to get an instance of the eventAdmin Service of the osgi.compendium an i packed a small project where this exception occurs.
the project has just the aim to get a reference to the eventAdmin Service with spring tools.
maybe you could give it a try ? please.
in the project there is only one OSGi class which sould autowired with an instance of the eventAdmin Service.
the eventAdmin service is defined in the bundle-context-osgi.xml.
the imports are all generated with spring-bundlor and an template definition.
hope anyone can find a solution for my problem.

i use a default virgo.webserver installation without any modifications and start all out of SpringToolsSuite (eclipse)

i would appreciate any help

thanks
