JasperReport is a popular reporting tool used by the Java programmer. Interestingly, what started as Teodor Danciu’s (creator of JasperReport library, 2001) need for an inexpensive reporting solution, has today bloomed into a full-fledged reporting library. This facilitated the need for a simple, inexpensive yet feature rich tool to add reporting capabilities in a Java application.

Much like other Java libraries, JasperReport is an API to facilitate reporting output in a variety of formats, be it, PDF, XML, HTML, XLS, etc. Further this library is not limited to adding reporting capabilities to web-based applications only; it can also be used to generate reports from desktop and console applications as well. In this article we shall see how to go hands on rather than delving into its architectural details.


Though it is a library like any other in Java, there are a few points to be noted while working with JasperReport.

1) Obviously, Jasper Library needs to be added to our project and some sort of layout has to be generated before we are able to start reporting from Java code.

2) Jasper’s reporting layout design is nothing but an XML file with the extension <filename>.jrxml.

3) This JRXML file is to be compiled to create <filename>.jasper. JRXML file can be compiled on the fly, dynamically from our Java code or we can use iReport or JasperStudio to visually design the JRXML file and then compile to create a Jasper file.

4) Once compiled and <filename>.jasper are created, we are done and can feed data into the report from the Java code.

Note: In this article, we shall be using NetBeans 8.0 and iReport5.5.0 plugin. This plugin was actually meant for Netbeans 7.4  but works fine for NetBeans 8.0 as well.

So What We Need

JasperReport heavily depends on other libraries such as Apache log4j, JFreeChart, Apache Commons, etc. As a result dependencies are a little sensitive regarding versions mismatch, especially when its files are downloaded and integrated from scattered locations. The good news is that JasperReport project contains everything we need. Once you download the zip file you need not worry. The details about the library and other needs, to go hands on in accordance to this article are as follows. The versions given here are the latest, at least the time of writing this article.

1.      JDK 8.0

2.      Netbeans 8.0

3.      iReport5.5.0 Netbeans 7.4 plugin

4.    JaspeReports-5.6.0-project

Installation and Configuration

  • Installing JDK and Netbeans is pretty straightforward, so I’m not going into the details.
  • Once the iReport5.5.0 plugin is downloaded, unzip it in any location. Open Netbeans, select Plugins from the Tools menu. From the Download tab select Add Plugins… and open all *.nbm files.

    Adding plugins
    Figure 1: Adding plugins

  • To create a JasperReport user defined library, select Libraries from the Tools menu. Click on the New Library… button at the bottom left corner of the window, give a Library Name → OK. Then click on Add Jar/Folder… and navigate to the location where you have unzipped JasperReport5.6.0 library and include everything from the lib and distfolders.

    Figure 2: Creating user defined library

Note: There is a huge list of jar files in the lib and dist folders of the Jasper library. Every project may not need all of the jar files, but it doesn’t hurt to create a reusable library in NetBeans with all the jars so that we can include it in our Java project without bothering about what jar to include and what not to include. This is especially helpful for beginners where identifying a particular jar may be difficult at times.

We are now ready to create a Java project with Jasper reporting.

Starting a Project

Creating a Simple Application with Jasper Reporting

1.    File –> New Project…

2.    Select Java from Categories and Java Application from Projects. Then Next.

3.    Give the name of the application and click Finish.

4.    Add JasperLibrary5.6.0 to the project by right clicking Libraries from the Project pane and Add Library and then import.

5.    Open the Files pane (Window –>  Files). Right click on the project root to create a folder named reports.

6.    Right click on the reports folder then select New → Empty report…

7.    Give the name of the report ‘report1’ and Finish.

Designing a Report

Open report1.jrxml in Designer view and use Report Inspector to design the report as in figure 4.

Report design in NetBeans
Figure 4: Report design in NetBeans

The corresponding XML details of the report1.jrxml are shown in Listing 1.

Listing 1: report1.jrxml

<?xml version="1.0" encoding="UTF-8"?>

Create a file inside the src folder. Without this, file compiler would complain such as:

log4j:WARN No appenders could be found for logger (net.sf.jasperreports.engine.xml.JRXmlDigesterFactory).
log4j:WARN Please initialize the log4j system properly.

Listing 2:

log4j.rootLogger=ERROR, stdout
log4j.appender.stdout.layout.ConversionPattern=%d %5p %c:%L - %m%n

Create Java Class

In the Java class we are creating a report from a model of table data. This is our basic data source in this project. We are also using JasperCompileManager to compile the jrxml file and produce .jasper file dynamically through Java code. This Jasper file is passed to the JasperPrint class along with table data from TableModel. JasperPrint object acts as a container of data from the data source. The report now is ready.

To view the report we then pass the initialized JasperPrint object to create a new JasperView object. JasperView extends Swing JFrame class and hence provides a GUI frame to display the report as in figure 5.

Listing 3:

//...import  statements
public class SimpleReport {    
    DefaultTableModel tableModel;
    public SimpleReport() {
        JasperPrint jasperPrint = null;
        try {
            jasperPrint = JasperFillManager.fillReport("reports/report1.jasper", new HashMap(),
                    new JRTableModelDataSource(tableModel));
            JasperViewer jasperViewer = new JasperViewer(jasperPrint);
        } catch (JRException ex) {
    private void TableModelData() {
        String[] columnNames = {"Id", "Name", "Department", "Email"};
        String[][] data = {
            {"111", "G Conger", " Orthopaedic", ""},
            {"222", "A Date", "ENT", ""},
            {"333", "R Linz", "Paedriatics", ""},
            {"444", "V Sethi", "Nephrology", ""},
            {"555", "K Rao", "Orthopaedics", ""},
            {"666", "V Santana", "Nephrology", ""},
            {"777", "J Pollock", "Nephrology", ""},
            {"888", "H David", "Nephrology", ""},
            {"999", "P Patel", "Nephrology", ""},
            {"101", "C Comer", "Nephrology", ""}
        tableModel = new DefaultTableModel(data, columnNames);
public static void main(String[] args) {
        new SimpleReport();

The above example is very simple yet effective method of getting hands on in one’s first Jasper report projects. The tags used in JRXML though looks like a simple XML yet needs further explanation; readers will get a thorough idea if JasperReport documentation is followed. In future articles we will delve a little deeper into how we can use JasperReport further to meet our reporting needs.
