Jersey Resource .class loading

I have the Jersey resource classes bundled within a larger WAR as JAR file which is now residing underneath WEB-INF/lib folder on Websphere Application Server. I have the correct web.xml entry(WEB-INF/web.xml) but still on the server, the scan appears to be not able to lookup the Resource classes which are bundled as a JAR. I was looking at a few threads, and the suggestion was to not bundle Resources as a JAR but instead load the classes seperately underneath /WEB-INF/classes.

<servlet-name>Jersey REST Service</servlet-name>
<servlet-class>com.sun.jersey.spi.container.servlet.ServletContainer</servlet-class>
 <init-param>
        <param-name>com.sun.jersey.config.property.packages</param-name>
         <param-value>blah.blah.blah</param-value>
 </init-param>
 </servlet>

com.sun.jersey.api.container.ContainerException: The ResourceConfig instance does not contain any root resource classes..at com.sun.jersey.server.impl.application.WebApplicationImpl.processRootResources(WebApplicationImpl.java:1064)
