unable to deploy restful application liberty profile 8.2 - websphere

Question

I am trying to deploy the RESTful webservices on liberty profile 8.5.5.2. I have enabled the jaxrs-1.1 feature in server and I am using Java 1.7. When I start the server it gives me following error:
[ERROR ] Uncaught.init.exception.thrown.by.servlet

Following is the entry in my web.xml file:
<servlet>
<servlet-name>JAX-RS Servlet</servlet-name>
<servlet-class>org.apache.wink.server.internal.servlet.RestServlet</servlet-class>
<init-param>
<param-name>javax.ws.rs.Application</param-name>
<param-value>com.example.RestfulResourceLoader</param-value>
</init-param>
<init-param>
<param-name>propertiesLocation</param-name>
<param-value>mobilehandler.properties</param-value>
</init-param>
<load-on-startup>1</load-on-startup>
</servlet>
<servlet-mapping>
<servlet-name>JAX-RS Servlet</servlet-name>
<url-pattern>/rest/*</url-pattern>
</servlet-mapping>
What other configuration I need to do in order remove this error?

WebSphere Liberty supports JAX-RS 1.1, so you dont need to provide servlet class, just use the following fragment in web.xml:
<servlet>
<servlet-name>javax.ws.rs.core.Application</servlet-name>
</servlet>
<servlet-mapping>
<servlet-name>javax.ws.rs.core.Application</servlet-name>
<url-pattern>/rest/*</url-pattern>
</servlet-mapping>

UPDATE
The HandlersFactory is from third party libraries, try to add the following classloader (in the server.xml) to your application to make library visible.
<webApplication... >
<classloader apiTypeVisibility="spec,ibm-api,api,third-party">
</classloader>
</webApplication>
