import net.sf.jasperreports.engine.design.JasperDesign;
import net.sf.jasperreports.engine.util.JRLoader;
import net.sf.jasperreports.engine.xml.JRXmlWriter;

class JasperToJrxmlConverter
{
   public static String sourcePath,outputPath;

   public static JasperDesign jd  = new JasperDesign();

   public static void main(String [] args) {
	   Long executionStartTime=new Long(0);
	   Long executionStopTime=new Long(0);
      // File Paths
      sourcePath = "D:\JasperTest\Template3.jasper";
      outputPath = "D:\JasperTest\Template3.jrxml";
      try
      {
    	  executionStartTime=System.currentTimeMillis();
    	 //JasperDesign jd=(JasperDesign)JRXmlLoader.load(sourcePath);
         //JRXmlWriter.writeReport(jd, outputPath);
    	 JasperReport jd = (JasperReport) JRLoader.loadObject(sourcePath);
    	 JRXmlWriter.writeReport(jd, outputPath, "UTF-8"«»);
    	 executionStopTime=System.currentTimeMillis();
    	 System.out.println("Successfully Decompiled Jsaper File Into JRXML File : n"«»);
    	 System.out.println("Total Time Taken Is : "+(executionStopTime-executionStartTime)+" msn"«»);
    	 System.out.println(" JRXML File Name And Location Are :n"«»);
    	 System.out.println(outputPath+"n"«»);
      }
      catch(JRException e)
      {
         e.printStackTrace();
