body: <p>I need to support resume on Jersey REST, I'm trying to do it this way:</p>
  
  <pre><code>@Path("/helloworld")
  public class RestServer {
  
  @GET
  
  @Path("say")
  @Produces("audio/mp3")
  public Response getMessage(@HeaderParam("Range") String r ) throws IOException{
      String str="/Users/dima/Music/crazy_town_-_butterfly.mp3";
  
      System.out.println(r);
      RandomAccessFile f=new RandomAccessFile(str, "r");
  
      int off=0;
      int to=(int)f.length();
      byte[] data ;
      if(r!=null){
          String from=r.split("=")[1].split("-")[0];
          String t=r.split("=")[1].split("-")[1];
          off=Integer.parseInt(from);
          to=Integer.parseInt(t);
  
      }
      data= new byte[to-off];
      f.readFully(data, off, to-off);
  
      ResponseBuilder res=Response.ok(data)
              .header("Accept-Ranges","bytes")
              .header("Content-Range:", "bytes "+off+"-"+to+"/"+data.length)
              .header("Pragma", "no-cache");;
  
              if(r==null){
                  res=res.header("Content-Length", data.length);
              }
              f.close();
  
              Response ans=res.build();
  
              return ans;
  
  
  }
