Thanks a lot Tommy for the detailed suggestion. It helps in a lot for me to
understand few things. As I am new to OSGi world so little bit confuse now..
Let us talk about this example now by which if I am able to solve the
problem then I would be able to solve my other problems too.. Below is my
code in which I am able to start the OSGi framework and then I am trying to
install GoldenlseyeStorageService bundle. And as soon as I try to install
the bundle, I always get the exception as I told you in my previous email .
*Unresolved constraint in bundle GoldenlseyeStorageService [1]: Unable to
resolve 1.0: missing requirement [1.0] osgi.wiring.package;
(&(osgi.wiring.package=com.host.kernel.logger)(version>=1.19.0)(!(version>=2.0.0)))
*
*
*
Below is the code:-
*
*
public class TestOSGi {
public static void main(String[] args) {
try {
FileUtils.deleteDirectory(new File("felix-cache"));
FrameworkFactory frameworkFactory =
ServiceLoader.load(FrameworkFactory.class).iterator().next();
Framework framework = frameworkFactory.newFramework(new
HashMap<String, String>());
framework.start();
final BundleContext bundleContext = framework.getBundleContext();
final List<Bundle> installedBundles = new LinkedList<Bundle>();
BundleActivator b = new org.ops4j.pax.url.mvn.internal.Activator();
b.start(bundleContext);
String localFilename =
"file:C:\\Storage\\GoldenlseyeStorageService-1.0.0.jar";
installedBundles.add(bundleContext.installBundle(localFilename));
for (Bundle bundle : installedBundles) {
bundle.start(); // this line throws me an exception
}
} catch (IOException e) {
e.printStackTrace();
} catch (BundleException e) {
e.printStackTrace();
} catch (Exception e) {
e.printStackTrace();
}
}
}
Now as you mention that the error mean is - the package the bundle wants to
import is not being exported by *any other bundle (which bundle are we
talking about here?)*, and thus cannot be imported. So here what I am
supposed to do? What should I do here to fix the problem?
Bcoz, I am installing only one bundle here which is bringing other
dependencies and I am not sure what I should do here to fix this problem.
As I am supposed to use lot of our company specific dependencies in my
pom.xml file..
The bundle (*GoldenlseyeStorageService *) that I am trying to install
depends on this maven dependency in its pom.xml file
<dependency>
<groupId>com.host.soa</groupId>
<artifactId>soaMerged</artifactId>
<scope>compile</scope>
<exclusions>
<exclusion>
<artifactId>axis2</artifactId>
<groupId>org.apache</groupId>
</exclusion>
</exclusions>
</dependency>
And the above maven dependency is bringing in kernelMerged dependency in
which this package is there- *com.host.kernel.logger. *
*
*
And I am supposed to use this package in my code..
Now I believe the suggestions you gave me is-
1) I should install kernelMerged jar as a Bundle before installing *
GoldenlseyeStorageService* , to solve this problem? Right?
Below is my full pom.xml file for *GoldenlseyeStorageService *bundle which
is what I am trying to install..

If you can guide me step by step then it will be great for me to fix this
problem.. Thanks for your time and help.
