my piece of code is

  @POST
  @Path("/getJSONCompareData")
  @Produces(MediaType.APPLICATION_JSON)
  public Object getJSONCompareData(@FormParam("testRunNum") String TRun,@FormParam("rptName") String reportName) {

   if(debugLevel>2)
      Log.debugLog(className, "getJSONStatsData", "", "", "Methad called");
      Object obj=null;
      try {
      int testRunNum = Integer.parseInt(TRun);
      String rptName = reportName;
      JSONParser parser=new JSONParser();
      String statsReportNameDir = Config.getWorkPath() + "/webapps/logs/TR" + testRunNum + "/reports/pareReports/" + rptName + "/pare.report";
                    obj=parser.parse(new FileReader(statsReportNameDir));
    }catch(Exception e){
      e.printStackTrace();
      Log.stackTraceLog(className, "getJSONStatsData", "", "", "Exception - ", e);
     }
          return obj;
   }

file size i am reading is approx 10MB

i want to press data as it is taking 1 min over network

How i press my Obj and handle in ajax call

my piece of code is

You can press JSON response using GZIP configuration on server.
Modern browsers supports gzip pressed content also Servers like Apache, Tomcat, JBoss etc supports gzip pression too.

Hence if gzip is enabled in server, it press's data then sends to client.
you can refer article http://viralpatel/blogs/enable-gzip-pression-in-tomcat/

GZIP pression will increase performance not only for js,jsp files but also for http requests as data will be pressed

For press data in Rest Service you have add(create) an annotation I have create an annotation name ** @Compress ** and implemented code for that on my server

import .cavisson.gui.server.webdashboard.services.interceptors.Compress;

here is my class for pression

package .cavisson.gui.server.webdashboard.services.interceptors;

import java.lang.annotation.Retention;
import java.lang.annotation.RetentionPolicy;
import javax.ws.rs.NameBinding;

    /**
     * @Compress annotation is the name binding annotation.
     */
    @NameBinding
    @Retention(RetentionPolicy.RUNTIME)
    public @interface Compress {}

now i have bind this interface with my class GZIPWriterInterceptor withuse at rum time

package .cavisson.gui.server.webdashboard.services.interceptors;

import java.io.IOException;
import java.io.OutputStream;
import java.util.zip.GZIPOutputStream;
import javax.ws.rs.WebApplicationException;
import javax.ws.rs.core.MultivaluedMap;
import javax.ws.rs.ext.Provider;
import javax.ws.rs.ext.WriterInterceptor;
import javax.ws.rs.ext.WriterInterceptorContext;

/**
 * This class is used for pressing data sending from server.
 */
@Provider
@Compress
public class GZIPWriterInterceptor implements WriterInterceptor
{
  @Override
  public void aroundWriteTo(WriterInterceptorContext context) throws IOException, WebApplicationException
  {
    try
    {
      MultivaluedMap<String,Object> headers = context.getHeaders();
      headers.add("Content-Encoding", "gzip");

      final OutputStream outputStream = context.getOutputStream();
      context.setOutputStream(new GZIPOutputStream(outputStream));
      context.proceed();
    }
    catch(IOException | WebApplicationException  e)
    {
      e.printStackTrace();
    }
    catch(Exception e)
    {
      e.printStackTrace();
    }
  }
}

              

my piece of code is

  @POST
  @Path("/getJSONCompareData")
  @Produces(MediaType.APPLICATION_JSON)
  public Object getJSONCompareData(@FormParam("testRunNum") String TRun,@FormParam("rptName") String reportName) {

      String rptName = reportName;

      String statsReportNameDir = Config.getWorkPath() + "/webapps/logs/TR" + testRunNum + "/reports/pareReports/" + rptName + "/pare.report";
                    obj=parser.parse(new FileReader(statsReportNameDir));
    }catch(Exception e){
