Mule upgrade 3.6 compiler error

I was working on mule 3.5.1, when I upgrade to mule 3.6 version, getting compile time error for following class:

import org.mule.module.jersey.MuleResponseWriter;
import com.sun.jersey.spi.container.ContainerResponse;


public class GLExportTransformer extends AbstractMessageTransformer {

    public List<GLExport> methodType(@Payload MuleResponseWriter content){
        List<GLExport> glExportList = (List<GLExport>) content;
        System.out.println("Java payload is -->"+glExportList.getClass());
        return glExportList ;
    } 

    @Override
    public Object transformMessage(MuleMessage message, String outputEncoding)throws TransformerException {
        ContainerResponse cr = (ContainerResponse) message.getInvocationProperty("jersey_response");
        List<GLExport> res = (List<GLExport>)cr.getResponse().getEntity();
        System.out.println("Response from QB is -->"+res);
        return res;   
    }

}

<custom-transformer name="StringToNameString" class="com.trinet.qb.utils.GLExportTransformer" doc:name="GL Export Transformer"/> 

Compile time error:

The type org.mule.module.jersey.MuleResponseWriter is not visible

The import com.sun.jersey cannot be resolved

How do I resolve this?

In my Anypoint Studio shows Mule3.6 uses all jersey related jar uses 2.11 version of jar files. Using Java 1.7 version.
