Jasper Reports export to EXCEL, CSV and PDF Using JRXML Java and My SQL

This Post will explain , How to export different formats using Jasper and Jrxml using java

Step 1: Download Download Jasper Studio
or I Report Designer

Step 2 : Design your page by providing connection details and query details and what columns needs to be display in PDF/excel/CSV

Step 3: Your design Page details can be mentioned in Summary Band.


Step 4: Once design completes , then it is time to write java class to export into different formats

Step 5: Excel report Generation

package arrayListTest;

import java.sql.Connection;
import java.sql.DriverManager;
import java.util.HashMap;

import net.sf.jasperreports.engine.JasperCompileManager;
import net.sf.jasperreports.engine.JasperFillManager;
import net.sf.jasperreports.engine.JasperPrint;
import net.sf.jasperreports.engine.JasperReport;
import net.sf.jasperreports.engine.export.JRCsvExporter;
import net.sf.jasperreports.engine.export.JRPdfExporter;
import net.sf.jasperreports.engine.export.JRXlsExporter;
import net.sf.jasperreports.export.SimpleCsvExporterConfiguration;
import net.sf.jasperreports.export.SimpleExporterInput;
import net.sf.jasperreports.export.SimpleOutputStreamExporterOutput;
import net.sf.jasperreports.export.SimplePdfExporterConfiguration;
import net.sf.jasperreports.export.SimpleWriterExporterOutput;
import net.sf.jasperreports.export.SimpleXlsReportConfiguration;

public class GenerateMultipleReportsFromJasper {
  public static void main(String[] args) {

  //Jrxml file source
  String sourceFileName = "C:\\Users\\Siva\\JaspersoftWorkspace\\csvpdf\\csv_export.jrxml";
  //destination file location
  String outXlsName = "C:\\Users\\Siva\\JaspersoftWorkspace\\csvpdf\\test.xls";
  //If we want to pass any parameters to jasper report, then we can use this map
  HashMap xlsParams = new HashMap();
  Connection con = null;
  try {
    // here employee is database name, root is username and password
    con = DriverManager.getConnection("jdbc:mysql://localhost:3306/employee", "root", "root");
    JasperReport report = JasperCompileManager.compileReport(sourceFileName );
    JasperPrint xlsPrint = JasperFillManager.fillReport(report, xlsParams, con);
    JRXlsExporter xlsExporter = new JRXlsExporter();
    xlsExporter.setExporterInput(new SimpleExporterInput(xlsPrint));
    xlsExporter.setExporterOutput(new SimpleOutputStreamExporterOutput(outXlsName));
    SimpleXlsReportConfiguration xlsReportConfiguration = new SimpleXlsReportConfiguration();
  } catch (Exception e) {
 if(con != null){
    catch(Exception ex){


Step 6: CSV Generation

HashMap csvParamsMap = new HashMap();
String outcsvName = "C:\\Users\\Siva\\JaspersoftWorkspace\\csvpdf\\test.csv";
JasperReport report1 = JasperCompileManager.compileReport(sourceFileName );
JasperPrint jasperPrint = JasperFillManager.fillReport(report1, csvParamsMap, con);
JRCsvExporter exporter = new JRCsvExporter();
exporter.setExporterInput(new SimpleExporterInput(jasperPrint));
exporter.setExporterOutput(new SimpleWriterExporterOutput(new File(outcsvName)));
SimpleCsvExporterConfiguration configuration = new SimpleCsvExporterConfiguration();

Step 7: PDF Generation

HashMap pdfParamsMap = new HashMap();
String outPdfName = "C:\\Users\\Siva\\JaspersoftWorkspace\\csvpdf\\test.pdf";
JasperReport report2 = JasperCompileManager.compileReport(sourceFileName );
JasperPrint jasperPrint2 = JasperFillManager.fillReport(report2, pdfParamsMap, con);
JRPdfExporter pdfExporter = new JRPdfExporter();
pdfExporter.setExporterInput(new SimpleExporterInput(jasperPrint2));
pdfExporter.setExporterOutput(new SimpleOutputStreamExporterOutput(outPdfName));
SimplePdfExporterConfiguration pdfConfiguration = new SimplePdfExporterConfiguration();

Step 8: Required jar file to execute this program

1. Itext 2.1.7.jar
2. commons-beanutils-1.9.2.jar
3. commons-logging-1.2.jar
4. commons-collections-3.2.1.jar
5. commons-lang-2.6.jar
6. commons-digester-1.6.jar
7. jasperreports-6.2.0.jar
8. mysql-connector-java-5.1.40.jar
9. poi-ooxml-3.16.jar
10. poi-3.12.jar

Step 9: Once We downloaded all jars then add into java build path.

Step 10: This is how we can export different format using jasper jrxml and Java.

Getting started with Kubernetes and Install Kubernetes on Windows , Tools for Kubernetes Cluster

1. What is Kubernetes?
It is an open source system for automating deployment, scaling and managing containerized applications

How to install Kubernetes?

1. Install Kube control(kubectl) on Windows
2. kubectl (kubernet command control tool) , used to run the commands in kubernetes clusters.
3. Before install, we have to make sure each client version has to work with minor difference with master
For example, a v1.2 client should work with v1.1, v1.2, and v1.3 master

4. Download from the given link Download Kubernetes
5. Add the binary in to your PATH.(System - Environment Variables)
6.Check the version using kubectl version

We can create sample cluster online using following link

Online interactive kubernetes cluster

Popular tools for kubernetes clusters
1. (Mini Kube)
2. Google Kubernetes Engine (GKE)
3. Amazon Elastic Kubernetes Service (EKS):
4. Azure Kubernetes Service (AKS)
