I have written following Code to intercept the incoming request.

@Provider
public class RequestInterceptor implements  ReaderInterceptor {
    @Override
    public Object aroundReadFrom(ReaderInterceptorContext context) throws IOException, WebApplicationException {
        Message message = PhaseInterceptorChain.getCurrentMessage();
        OperationResourceInfo cri = message.getExchange().get(OperationResourceInfo.class);
        return null;
    }
}

I am using Apache CXF 3.1.10 and Liberty Profile 16.

In my server.xml, following features are enabled : 

<featureManager>
    <feature>webProfile-7.0</feature>
    <feature>localConnector-1.0</feature>
</featureManager>

Following is my pom.xml file:

    </dependencies>

When I am running the application I am getting below error:

[INFO    ] Setting the server's publish address to be /rest/
[INFO    ] SRVE0242I: [TestApp] [/TestApp] [javax.ws.rs.core.Application]: Initialization successful.
[ERROR   ] SRVE0777E: Exception thrown by application class 'framework.rest.interceptors.RequestInterceptor.aroundReadFrom:32'
java.lang.NoClassDefFoundError: org/apache/cxf/phase/PhaseInterceptorChain
    at framework.rest.interceptors.RequestInterceptor.aroundReadFrom(RequestInterceptor.java:32)
    at org.apache.cxf.jaxrs.utils.JAXRSUtils.readFromMessageBodyReader(JAXRSUtils.java:1356)
    at [internal classes]

If I am running my application without the interceptor code then its running just fine.

  • This is caused by a classloading conflict between Liberty's CXF impl and one that you have bundled in your app. Since the `webProfile-7.0` feature includes the `jaxrs-2.0` feature (and its API), can you simply not package the CXF implementation in your app? – Andy Guibert Mar 23 '17 at 22:16
  • It still giving me the errors: Do you know the Liberty's CXF impl Version number? – Prerak Tiwari Mar 23 '17 at 22:34
  • it depends on your exact liberty version, but you can check in `${wlp.install.dir}/lib/com.ibm.ws.org.apache.cxf-rt-core.X.X.jar` to see what version liberty uses – Andy Guibert Mar 23 '17 at 22:36
  • For my liberty..its com.ibm.ws.org.apache.cxf-rt-core.2.6.2_1.0.14 – Prerak Tiwari Mar 23 '17 at 22:39
  • I removed the jar CXF jar from war file but still I am getting the same error...Is there anything else I can do about it? – Prerak Tiwari Mar 23 '17 at 22:43

Did you have just cxf-rt-frountend-jaxrs-x.x.x.jar packaged in your application? PhaseInterceptorChain.class is in cxf-core-x.x.x.jar. Perhaps try including all cxf jars in the lib directory of your .war.
