Hi Joel,
Thanks for the quick response.
Our current usage is below. Could you guide me in using the new class and write method. 

public class customSearchHandler extends SearchHandler {@Override

public void inform(SolrCore core)

{

   super.inform(core);
…. 

core.registerResponseWriter("xsort", new SortingResponseWriter(){
   @Override
   public void write(Writer out, SolrQueryRequest req,SolrQueryResponse response) throws IOException {
      try {
         if (handleResponseWriter) {
            CustomController.singleton.prepareThreadForWork();
         } 
         super.write(out, req,response);
      }
      finally {
         CustomController.singleton.releaseFromThread();
      }
   }
});
}

Signature of new class isExportWriter(SolrQueryRequest req, SolrQueryResponse res, String wt) {public void write(OutputStream os) throws IOException {

 The functionality should be exactly the same. The config files though need
to be changed. I would recommend adding any custom configs that you have to
the new configs following the ExportWriter changes.
