Subject [jira] [Commented] (CXF-6904) Unable to read swagger annotations if the file is in another osgi bundle
Date Wed, 18 May 2016 11:02:12 GMT


Akitoshi Yoshida commented on CXF-6904:

I am looking into it.
It seems there is some limitation (or strange behavior) in in.reflections to look up a package
under osgi.
when it is looking up demo.jaxrs.swagger.server using its ClasspathHelper.forPackage with
impl's bundle, it doesn't look up into api's bundle.
when it is looking up  demo.jaxrs.swagger.server.Sample.class using its ClasspathHelper.forResource
with impl's bundle, it does look up into api's bundle.
i think i have some temporary workaround.
will update it today.

>   mvn install (on the example)
>   bin/karaf (I used the current karaf 4.0.5)
>   on karaf@root()>
>   feature:repo-add cxf 3.1.6

> It may happen that one component is complaining about a missing guava class even if you
provided it before. All you have todo is copy guava-18.jar into your deploy folder. I think
this is a karaf bug. I have to create a ticket for. After you place the guava file into your
deploy folder and type list, all bundles should be active.  
>   Now open your web browser and type: 
>   http://localhost:8181/cxf/swaggerSample/swagger.json
>   And all you see is the swagger header.
>   I guess the problem is the ClasspathHelper.class from org.reflections it looks like
that this one is not able to access the osgi component. 
>   The behavior is similar to this error description:
