Java Reporting With Jasper Reports - Part 2

Welcome back to Java Reporting series. For those who didn't read the introductory article; have a look here before we get started. Today we're going to have a quick tour in JasperReport architecture, development lifecycle, report definition files, and finally we're going to set up our environment and start work in a sample application.

Architecture

As shown in the above figure JasperReports architecture is based on declarative XML files which by convention have an extension of jrxml that contains the report layout. A lot of third-party design tools were produced to generate your jrxml file in a smooth way (like iReport or JasperAssistant) Design file is supposed to be filled by report's result which is fetched from database, XML files, Java collection, Comma-separated values or Models. Jasper can communicate with those data-sources and more, it can merge any number of data-sources together and manipulates the results of any combinations. This communication goes through JDBC, JNDI, XQuery, EJBQL, Hibernate or existing Oracle PL/SQL. You also can define your own data-source class and pass it to jasper engine directly. After defining your report design layout in jrxml format and determining your data source(s) jasper engine does the rest of work. It compiles your design file and fills it with results fetched from data-source and generates your report to the chosen exporting format (PDF, Excel, HTML, XML, RTF, TXT …, etc.)

Report Definition file structure (jrxml):

Jasper design file –jrxml- contains the following elements:

<jasperReport>: the root element.
<title>: its contents are printed only once at the beginning of the report
<pageHeader> - its contents are printed at the beginning of every page in the report.
<detail> - contains the body of the report, repeated by n number of results
<pageFooter> - its contents are printed at the bottom of every page in the report.
<band> - defines a report section, all of the above elements contain a band element as its only child element.

Only the root element is mandatory, the rest of elements are optional.

Environment

To set up working environment we need to download JasperReport jar file from the following URL: http://sourceforge.net/project/showfiles.php?group_id=36382&package_id=28579
And add the following jars to your project classpath:

jasperreports-2.0.4.jar
commons-digester-1.7.jar
commons-collections-2.1.jar (commons-collections.jar)
commons-logging-1.0.2.jar
commons-beanutils.jar
iText-2.0.7.jar (used infor PDF exporting)

Sample application

At this section we'll introduce a sample application that generates PDF, HTML and Excel files contain the results of our report which is built over Oracle database contains the following table:

ITEM

ITEM_ID ---- NUMBER(5) --- NOT NULL
CATEOGRY_ID ---- NUMBER(5) --- NOT NULL
ITEM_NAME ---- VARCHAR2(50) --- NOT NULL
ITEM_DESCIPTION ---- VARCHAR2(200)

ITEM_AMOUNT ---- NUMBER(5) ---- NOT NULL

Result: Report should retrieve the items with amount less than or equal 100 item.

We're going to divide the work into two steps:

Generate the report design (jrxml file).
Implement application that assigns data source, compiles jrxml file and exports result in the chosen format.

Designing The Report

First we create new text file and rename it to sample_report.jrxml, this file should contain the following XML tags.

<!DOCTYPE jasperReport PUBLIC
"//JasperReports//DTD Report Design//EN"
"http://jasperreports.sourceforge.net/dtds/jasperreport.dtd">

<jasperReport name="sample_report" >
<queryString>
<![CDATA[select item_name,item_amount from item
where item_amount <=100]]>
</queryString>
<field name="ITEM_NAME" class="java.lang.String"/>
<field name="ITEM_AMOUNT" class="java.math.BigDecimal"/>
<columnHeader>
<band height="28" isSplitAllowed="true">
<staticText>
<reportElement x="40" y="11" width="193" height="15" key="staticText-1"/>
<text>
<![CDATA[Item Name]]>
</text>
</staticText>
<staticText>
<reportElement x="330" y="11" width="193" height="15" key="staticText-2"/>
<text>
<![CDATA[Item Amount]]>
</text>
</staticText>
</band>
</columnHeader>

<detail>
<band height="27" isSplitAllowed="true">
<textField>
<reportElement x="47" y="6" width="173"
height="18" key="textField"/>
<textFieldExpression class="java.lang.String">
<![CDATA[$F{ITEM_NAME}]]>
</textFieldExpression>
</textField>
<textField >
<reportElement x="330" y="6" width="100"
height="18" key="textField"/>
<textFieldExpression class="java.math.BigDecimal">
<![CDATA[$F{ITEM_AMOUNT}]]>
</textFieldExpression>
</textField>
</band>
</detail>
</jasperReport>

The above XML file consists of the following main sections that defining report behavior and layout:

<queryString>: contains the SQL statement which retrieves the report result.
<field name>: defines the resulted fields from the query, and give them name to reuse them into the report body [they are case-sensitive].
<staticText>: contains the header titles "Item Name" in <![CDATA[Item Name]]> tag format.
<textFieldExpression>: defines the appearance of result field.
$F{ITEM_NAME}: is a variable contains the value of Query result predefined field in the tag <field name>.

Once we finished the report design file, save it in C:\ directory.

Implementing The Report Service:

- Create a new java project.
- Import the jars listed in environment section to your project libraries.
- Create new class and import the following packages

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

import net.sf.jasperreports.engine.JRException;
import net.sf.jasperreports.engine.JRExporterParameter;
import net.sf.jasperreports.engine.JasperCompileManager;
import net.sf.jasperreports.engine.JasperExportManager;
import net.sf.jasperreports.engine.JasperFillManager;
import net.sf.jasperreports.engine.JasperPrint;
import net.sf.jasperreports.engine.JasperReport;
import net.sf.jasperreports.engine.export.JRXlsExporter;

- Define the data source, in my case it's an oracle connection and established by JDBC as following:

public static Connection establishConnection()
{
Connection connection = null;
try
{
Class.forName("oracle.jdbc.driver.OracleDriver");
String oracleURL = "jdbc:oracle:thin:@localhost:1521:mySID";
connection = DriverManager.getConnection(oracleURL,"username","password");
connection.setAutoCommit(false);
}
catch(SQLException exception)
{
exception.printStackTrace();
}
return connection;

}

Finally, the core code for compiling, filling and exporting the results in the following sequence:

- Define jasper objects that will hold report template, compiled files, and result files.

/* JasperReport is the object
that holds our compiled jrxml file */
JasperReport jasperReport;


/* JasperPrint is the object contains
report after result filling process */
JasperPrint jasperPrint;

- Create a connection to my data-source; initialize the report parameter into empty HashMap then compile our jrxml file into JasperReport object and finally fill the JasperPrint object by data from data-source connection.

// connection is the data source we used to fetch the data from
Connection connection = establishConnection(); 
// jasperParameter is a Hashmap contains the parameters
// passed from application to the jrxml layout
HashMap jasperParameter = new HashMap();

// jrxml compiling process
jasperReport = JasperCompileManager.compileReport
("C://sample_report.jrxml");

// filling report with data from data source

jasperPrint = JasperFillManager.fillReport(jasperReport,jasperParameter, connection);

- Last segment of code is responsible for exporting the result files into different formats

// exporting process
// 1- export to PDF
JasperExportManager.exportReportToPdfFile(jasperPrint, "C://sample_report.pdf");

// 2- export to HTML
JasperExportManager.exportReportToHtmlFile(jasperPrint, "C://sample_report.html" ); 

// 3- export to Excel sheet
JRXlsExporter exporter = new JRXlsExporter();
exporter.setParameter(JRExporterParameter.JASPER_PRINT, jasperPrint);
exporter.setParameter(JRExporterParameter.OUTPUT_FILE_NAME, "C://simple_report.xls" );

exporter.exportReport();

You have just managed to generate your first jasper report in 3 different file formats at C:\\ directory (shown in the image below):

- sample_report.html
- sample_report.pdf
- sample_report.xls

Here we reach the end of today's article, next article we will cover the following points:
1- Using design tool (iReport) to generate robust and smooth jrxml file.
2- Create run-time search criteria and pass them to report.

hello,

t the begining i was too happy by finding this tutorial, but after trying it , it doesn't work, there are 51 errors that talk about "symbols not found" , do you know the cause of these problems(i will send you the stack trace if you want), in fact i used commons-logging-1.1.jar instead of commons-logging-1.0.2.jar and itext-1.3.1.jar instead of iText-2.0.7.jar

i need your help,

thank you

@ chflb

I guess you didn't read the rest of articles, there were two more articles that cover working with designing tools to facilitate report design and remove the overhead of XML work.

you can find those articles at the following URL's:

http://java.dzone.com/articles/java-reporting-%E2%80%93-part-3

http://java.dzone.com/articles/java-reporting-%E2%80%93-part-4

try to figure them out, if you still facing problems don't hesitate to contact me directly.

hello hossam, thank you for your reply,

in fact,i have the jrxml file created, 'd like to say also that i use jsf+jpa

this is my code(the procedure responsable for compiling and exporting pdf) :

  public String generate() 
  {
     try{
 Connection connection = establishConnection();   
 HashMap jasperParameter = new HashMap();  
JasperReport  jasperReport = JasperCompileManager.compileReport ("E://rapport/rpt.jrxml");  
JasperPrint jasperPrint = JasperFillManager.fillReport(jasperReport,jasperParameter, connection); 
   JasperExportManager.exportReportToPdfFile(jasperPrint, "E://rapport/sample_report.pdf");  
   
     }catch(ClassNotFoundException ex)
     {ex.printStackTrace();}
     catch(JRException jr){jr.printStackTrace();}
     
return "generate";

there are in result 51 errors,(perhaps they will be stupid errors) ;

hello houssem,

i found the solution,in fact there is another jar to be imported, the jar is: jdt-compiler-X.jar,

thank you very much about these series,i hope next time you make a tutorial about how to use JasperServer, because i need now to put the generated pdfs in server to be consulted by the administrator,

any way, I thank you so much,

the code i use to generate the report is:

HashMap map = new HashMap();

Connection con = new connect().odbcConnect();

String reportFile = "E://Projects//NetBeansProjects//kusda//src//kusda//members.jrxml";

try {

Hi Hossam, Is there a way I can embed the jasper report into an iframe? I tried out the sample code suggested here: http://edwin.baculsoft.com/2010/11/creating-web-based-reports-using-jasper-report/ I am using jsp+servlet in my web application to try this out. All of that is working as expected. But I would like to render the report inside an iframe. Any help in this regard is highly appreciated.

Thank you for your post Mr.Hossam Sadik,

it help me alot.. now I am able to generate my report in EXCEL format and also in CSV format.. without making any change in .jrxml code, before this I was generating PDF file

...

I have a simple code which create a pdf page in new window with .jrxml file

JasperReport jasperReport;
JasperPrint jasperPrint;
connection=MyConnection.getConnection(); /*Myconnection class here is used to establish connection that i have created. */

ServletContext sc1 = getServletContext();
Map jasperParameter = new HashMap();

ServletContext sc = getServletContext();
String rPath = sc.getRealPath("/WEB-INF/jsp/jasper/report23.jrxml");/* change path according to your project */

jasperReport = JasperCompileManager.compileReport(rPath);
jasperPrint = JasperFillManager.fillReport(jasperReport,jasperParameter, connection);

byte [] abc=JasperExportManager.exportReportToPdf(jasperPrint);

ServletOutputStream ob=response.getOutputStream();
response.setContentType("application/pdf");

ob.write(abc,0,abc.length);
ob.flush();
ob.close();

This is really helpful. JasperReports provides the necessary features to generate dynamic reports, including data retrieval using JDBC as well as support for parameters, expressions, variables, and groups. - DR Marketing Group

I am using ireport for reporting tool as plugin in netbeans 7.1.1.

I have designed the jrxml file through ireport but unable to compile it to any format when using it in a jsp page.m getting a blank page output.

Here is my jrxml file code---------------

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

<![CDATA[select * from tma_dept where dept ='Civil';]]>

</queryString>

</background>

<title>

<image>

</image>

</staticText>

</band>

</title>

</pageHeader>

<line>

</graphicElement>

</line>

</columnHeader>

</textField>

</detail>

</columnFooter>

</textElement>

</pageFooter>

</summary>

</jasperReport>

Here is my jsp code------------------

<%@page import="net.sf.jasperreports.view.JasperViewer"%>

<%@ page language="java" contentType="text/html; charset=ISO-8859-1"

pageEncoding="ISO-8859-1"%>

<html>

<%@page import= "net.sf.jasperreports.engine.JRException"%>

String input = "./report/dept_report.jrxml";

String output = "./report/dept_report.html";

Connection con = null;

JasperReport jasperReport;

JasperPrint jasperPrint;

try

{

Class.forName("com.mysql.jdbc.Driver");

con = DriverManager.getConnection("jdbc:mysql://localhost:3306/tma","root","root");

out.println("inside con");

HashMap jasperParameter = new HashMap();

out.println("inside hash map");

jasperReport = JasperCompileManager.compileReport(input);

out.println("inside jasperReport"+jasperReport);

jasperPrint = JasperFillManager.fillReport(jasperReport,jasperParameter, con);

JasperExportManager.exportReportToHtmlFile(jasperPrint,output);

//JasperViewer.viewReport(jasperPrint);

//JRXlsExporter exporter = new JRXlsExporter();

//exporter.exportReport();

catch (Exception ex) {

finally {

con.close();

</body>

</html>

KINDLY SUGGEST ME WHERE AM I WRONG?
