osgi捆绑如何知道接口？

Question

I'm learning dealing with osgi bundles using apache felix. I'm using maven-bundle-plugin to generate the manifest file.

I created a first bundle that contains only an interface and I export it to be used by others. The second bundle contain a class that implements the interface created in the first bundle. I configured the second bundle to import the package exported by the first one.

When I compile the second bundle, I get an error telling me that he can not resolve the interface.

I'm not sure that I understood how bundles works ...

Thank you very much ...

[ Edit ] More information : I got the error when I compile using maven :

[INFO] Compilation failure
....../ServeurImpl.java:[17,36] error: cannot find symbol

ServeurImpl.java (line 17) :

public class ServeurImpl implements Serveur {

Serveur is an interface created in the first bundle.

Since your deploying the API in a separate bundle you would need something in the pom.xml file of the bundle implementing the API to say its available.

In your pom.xml put something like this:

    <dependency>
        <groupId>the.group</groupId>
        <artifactId>Serveur</artifactId>
        <version>0.0.1-SNAPSHOT</version>
        <type>bundle</type>
        <scope>provided</scope>
    </dependency>

'Provided' means the container would provide it... you said Felix.

Hope that helps.
