I have a simple OSGi bundle written and here is the source file. When I install it in a equinox OSGi container it does not get resolved it automatically. Can someone explain what I'm doing wrong here??.
package org.sample.api;
/**
* Created on 3/11/14.
*/
public interface Hello {
void sayHello();
}
This is the pom.xml file of the bundle.

Please post the generated MANIFEST.MF from the jar. I cant see anything wrong with the pom.
If the bundle is not resolved, in what state is it then? Installed? One possible reason could be that some of the transitive dependencies of the bundle are not available on the container.
P.S: You may want to use the latest version 2.4.0 for the maven-bundle-plugin.

I hope you are refreshing and starting the bundle after you install it.
refresh 7
start 7
where 7 is your bundle id.
Looks like you don't have a Activator with your bundle, at least your given sample doesn't contain one and your output for the generated Manifest doesn't contain a Bundle-Activator part. At this point I'd say your bundle is just in resolved state since it can't be active.
INSTALLED state is not an error condition. It just means that the bundle has been installed, which is true.
If you do see an actual error message, please provide the details.

I am developing an Eclipse plugin. That is using UI and file resources. Which required org.eclipse.core.resources;bundle-version="3.8.101" and filed if this dependency is not available on target eclipse.
Eclipse version: Juno (for Android development).
I want to install this jar if not available on target Eclipse. So my plugin run without any issue for target Eclipse.

Cannot complete the install because one or more required items could not be found.

I try to build a java project with eclipse.
During the complilation I have error java.lang.RuntimeException: No application id has been found. So I read that I need to add required plugins. I went to Run Configuration -> Plug-ins tab, push button Add Required Plug-ins and then validate plug-ins. I have my own plugin in the project. So I get com.blablabla is missing. How can I add my plugin to plugins list?

I have a bundle A that depends on bundle B. When code in bundle A runs and accesses a class from bundle B then the state of bundle B is resolved (4) instead of active (32) and the activator of bundle B didn't run as well. I assume there's something wrong the manifest of bundle B but I can't quite spot it.
This is the manifest of bundle B, generated with bnd.

Sigh. I bet you run on Equinox. In their eternal wisdom the Eclipse guys decided not to start bundles, being afraid it would overload the system. Trying to get a bundle started is REALLY overly complex in Eclipse. However, in your case there is a simple solution: OSGi Activation Policy. This will start your bundle when the first class is loaded. Just add to B
Bundle-ActivationPolicy: lazy
i just migrated from Equinox to Apache Felix. Now there is the javax.sql.datasource class missing:
java.lang.NoClassDefFoundError: javax/sql/DataSource
My bundle is importing javax.sql in the manifest file and i tried to add the following line to the felix config:
org.osgi.framework.system.packages.extra=javax.sql
Is there any way to teach felix to export the bundle or is there a bundle that does it? It worked fine in Equinox even without the import statement in the manifest.
EDIT:
The manifest file:
Manifest-Version: 1.0
Bundle-ManifestVersion: 2
Bundle-Name: Database
Bundle-SymbolicName: ...database
Bundle-Version: 1.0.0

Thanks,

Felix does already export this package.
More likely is that there may be something wrong with your Import-Package statement. You did state that your bundle imports the package, but please post a copy of your MANIFEST.MF to be sure.
I have made a small API Bundle and a service bundle that should use the API.
In my maven pom.xml file, i added a dependecy for my api bundle in the correct version like this:
<dependency>
<groupId>at.foobar.osgi.api</groupId>
<artifactId>foobarapi</artifactId>
<version>1.0</version>
</dependency>
i'm using the maven-bundle plugin to create the bundles, and because of that i used mvn clean install to create by jar file.
The Manifest looks like this (the service):
Manifest-Version: 1.0
Private-Package: at.foobar.osgi.producer
Built-By: foobar
Tool: Bnd-0.0.238
Bundle-Name: foobarproducer
Created-By: Apache Maven Bundle Plugin
Bundle-Version: 1.0
Build-Jdk: 1.6.0_26
Bnd-LastModified: 1332185439257
Bundle-ManifestVersion: 2
Bundle-Activator: at.foobar.osgi.producer.Activator
Import-Package: at.foobar.osgi.api,org.osgi.framework;version="1.4"
Bundle-SymbolicName: at.foobar.osgi.producer.foobarproducer
which seems to be OK for me. The import is in there, so everything should be fine.
now i started up equinox and installed the API and the producer bundle.
Then i startet the API, which worked out fine. But when i want to start the Producer Service i get this error:
org.osgi.framework.BundleException: The bundle "at.foobar.osgi.producer.foobarproducer_1.0.0 [4]" could not be resolved. Reason: Missing Constraint: Import-Package: at.foobar.osgi.api; version="0.0.0"
It seems that the framework cannot find the api, but its installed and started?
Make sure that you are exporting the API packages, so that your service bundle can bind to them.
In your maven-bundle-plugin for the API bundle you should have something like:
<configuration>
<instructions>
<Import-Package>
*
</Import-Package>
<Export-Package>
at.foobar.osgi.api.*
</Export-Package>
</instructions>
</configuration>
