Hi all,
I must use CXF (client) within a RCP (eclipse) application. Here's my config:
- I have defined a plugin project that contains a library with the code that
makes the CXF call (actually uses WebClient). This bundle A imports
org.apache.cxf.bundle-minimal (Require-bundle) and specifies the library in the
Classpath header of the MANIFEST.
- My OSGi runtime contains servicemix's jsr311 bundle, and this bundle is the
only provider of javax.ws.rs.*
- I'm using Gemini blueprint to expose the service defined in the library of
bundle A
- Bundle B (ui bundle) imports service defined in bundle A, also using Gemini
blueprint facilities.
- When invoking the service from B, it tries to create a WebClient to issue a
http request, and I get the following error:

Based on what I know from FactoryFinder, it tries to load a file named
META-INF/services/javax.ws.rs.ext.RuntimeDelegate, that contains the
implementation class name of the RuntimeDelegate to use. If either the file or
the class defined in the file cannot be loaded, it tries to load the default
RuntimeDelegate implementation, which is com.sun.ws.rs.ext.RuntimeDelegateImpl.
Thus getting this exception.
org.apache.cxf.bundle-minimal contains a file named
META-INF/services/javax.ws.rs.ext.RuntimeDelegate, and this file contains a
class name that exists in cxf bundle, thus I rather suspect some classloading
issues related to bundles since CXF and servicemix jsr311 are in separate
bundles.
Did anybody already face such an issue ?
Thanks in advance,
