Has anyone tried to get WireMock running in an OSGi-Environment?

[tomakehurst]

This is the first time I've heard of anyone trying to run it inside an OSGi container.

Are you using the standalone JAR (via the standalone classifier in the dependency) or the standard one?

[JanLoebel]

I've tried both, but couldn't find a difference between the exceptions.

[tomakehurst]

My best suggestion would be to try and match the commons-logging version you're deploying with your container with the version used by Apache HTTP Client 4, which I believe is version 1.1.1.

[bmuskalla]

Jan, Tom, I'm currently running Wiremock in an OSGi environment but included as a lib on the bundles classpath and not as a bundle on its own. The error you're getting might be related to the isolated classloaders. How do you deploy wiremock within pax exam right now?

Tom, I'd like to actually consume Wiremock as an OSGi bundle. Happy to provide a pull request to generate the necessary bits (MANIFEST.MF) as part of the gradle build.

[tomakehurst]

I'd be happy to receive a pull request for this. I barely used OSGi, so it be good to get a patch from someone with some experience with it.

[JanLoebel]

I tried different ways to bundle and deploy it to OSGi via PaxExam.

Verison 1:

public Option[] config() {
    return options( systemProperty( "pax.exam.osgi.unresolved.fail" ).value( "true" ),
         systemProperty( "org.ops4j.pax.logging.DefaultServiceLog.level" ).value( "DEBUG" ),
         junitBundles(),
         wrappedBundle( maven( "com.github.tomakehurst", "wiremock" ).version( "1.30" ))
         // All other dependencies from wiremock... 
    );
}

Version 2:
In Version 2 i used the bundle-plugin from maven to inline all dependencies and export the needed packages. But it also failed with the same error.

I would also appreciate a pull-request!

[ChristophSchaal]

Hi, I have the same issue that @JanLoebel describes.

@bmuskalla: Can you post your solution (the MANIFEST.MF) in this issue or provide the pull request?
