earlier deploying same application on websphere 7 , working fine. know websphere 8.5 comes wink jars removed jars ear , deployed on server. also, enabled verbose class loading on server , found class loading when server starts. though, when checked in class loader viewer console couldn't found class. adding jars shared library did not work me. great if can point me right direction solve error.

edit

following statement giving error inside handler:

searchresult result = context.getattribute(org.apache.wink.server.internal.handlers.searchresult.class); 

was 8.5 comes inbuilt apache wink 1.1. can follow these steps migrate application on 8.5:

1) remove apache wink jar application lib folder.

2) building application can use these 2 websphere jar, com.ibm.ws.prereq.jaxrs.jar , com.ibm.ws.prereq.jackson.jar. can find these jars in was_home/plugins folder.

3) build application these jars not package these jars application ear or war.

4) if application type ear make sure restful resources , class extends application class part of war.

5) redeploy application, should work fine now.
