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)



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

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.
