 Hi,
I have a widget that invokes a servlet that is deployed as war file on IBM Liberty (6.0.6).

When the application was deployed initially, it was not working as expected. Upon further investigation, the following exception was observed in the logs :
[ERROR ] SRVE0777E: Exception thrown by application class 'org.apache.wink.common.internal.registry.metadata.ProviderMetadataCollector.parseAccessibleObject:122'
java.lang.NoSuchMethodError: org/apache/wink/common/internal/utils/GenericsUtils.getClassType(Ljava/lang/reflect/Type;Ljava/lang/Class;)Ljava/lang/Class; (loaded from file:/ngtfs01/IBM/RQM606_Liberty/server/liberty/wlp/lib/../dev/api/third-party/com.ibm.websphere.appserver.thirdparty.jaxrs_1.0.20.jar by org.eclipse.osgi.internal.loader.EquinoxClassLoader@eaeb8095[com.ibm.ws.jaxrs:1.0.20.cl180120180309-2209(id=124)]) called from class org.apache.wink.common.internal.registry.metadata.ProviderMetadataCollector (loaded from file:/ngtfs01/IBM/RQM606_Liberty/server/liberty/servers/clm/workarea/org.eclipse.osgi/82/data/cache/com.ibm.ws.app.manager_63/.cache/WEB-INF/lib/wink-common-1.4.jar by com.ibm.ws.classloading.internal.AppClassLoader@64e52729).

I tried to overcome this exception by including third-party libraries using classloader option in application.xml
<classloader apiTypeVisibility="spec, ibm-api, api, stable, third-party" />

Although the above exception seems to have resolved, there are traces of other exceptions as follows :

[2/25/20 15:50:17:634 EST] 00000045 com.ibm.ws.logging.internal.impl.IncidentImpl I FFDC1015I: An FFDC Incident has been created: "java.lang.RuntimeException com.ibm.ws.anno.targets.internal.AnnotationTargetsImpl_Targets 529" at ffdc_20.02.25_15.50.17.0.log

And

Ensure that the class is not abstract, has a valid constructor, has the right visibility, and is not an inner member class.

Caused by: java.lang.ClassNotFoundException: org.apache.wink.json4j.JSONException cannot be found by com.ibm.ws.jaxrs_1.0.20.cl180120180309-2209

Can you kindly help me resolve the above exceptions ?


Thanking You
Satish Rajanna

 I was referring to the Eclipse Lyo client libraries - meant for the oslc-java-client lib.


This question needs to be asked on the eclipse lyo community.  We basically respond on queries pertaining to ELM solutions.

 This appears to be some kind of issue that is not really related to this forum. The question lacks vital information what APIs and frameworks are in use. Assuming it is Eclipse Lyo, I would suggest to ask on the Lyo forums and to provide the details about the implementation needed to understand the context. The person asking the original question did not follow up, so I will close the question now.

 Hi Muralidhar,


I updated maven configuration to pull the latest version for OSLC4J and dependencies. I did not get what you meant lyo client, if you were referring to oslc-java-client, I have the latest version. With this build the exceptions are still being thrown.

Thanking You
