I have deployed the RESTful application using Apache Wink packaged in EAR on WebSphere 8.5.5.2 ND. When the application starts it gives me the "Initialization successful" message:

Earlier I was deploying the same application on WebSphere 7 and it was working fine. I know that WebSphere 8.5 comes with Wink Jars so I removed those jars from EAR and then deployed it on the server. Also, I enabled verbose class loading on my server and found that class is loading when the server starts. Though, when I checked in Class Loader Viewer from console I couldn't found the class. Adding the jars to Shared Library also did not work for me. It would be great help if someone can point me to right direction to solve this error.
Edit
Following statement is giving error inside the handler:
SearchResult result = context.getAttribute(org.apache.wink.server.internal.handlers.SearchResult.class);
WAS 8.5 comes with inbuilt Apache Wink 1.1. You can follow these steps to migrate your application on WAS 8.5:
1) Remove all the apache wink jar from your application lib folder.
2) For building your application you can use these two websphere jar, com.ibm.ws.prereq.jaxrs.jar and com.ibm.ws.prereq.jackson.jar. you can find these jars in WAS_HOME/plugins folder.
3) Build your application with these jars but do not package these jars into your application EAR or WAR.
4) If your application type is EAR then Make sure all the restful resources and the class which extends Application class are part of war.
5) Redeploy your application, it should work fine now.
