create report with java

[dushantha Rathnayake]

Hi,

I am new to this report part. I downloaded ireport 3.7. And now I can design a report using ireport. Now I want to generate reports using a java application. I search through the internet and get some source cods. but that cods are with errors. Please help me to do this. I am using jdk 1.6.0_18 only and what is " import net.sf.jasperreports.engine.*; " ?

thank you.

import net.sf.jasperreports.engine.*;
import net.sf.jasperreports.engine.export.*;
import java.util.*;
			
public class JasperTest {

    public static void main(String[] args) {
        String fileName = "report1.jasper";
        String outFileName = "report1.pdf";
        HashMap hm = new HashMap();
        try {
            // Fill the report using an empty data source
            JasperPrint print = JasperFillManager.fillReport(fileName, hm, new JREmptyDataSource());
            
            // Create a PDF exporter
            JRExporter exporter = new JRPdfExporter();
            
            // Configure the exporter (set output file name and print object)
            exporter.setParameter(JRExporterParameter.OUTPUT_FILE_NAME, outFileName);
            exporter.setParameter(JRExporterParameter.JASPER_PRINT, print);
            
            // Export the PDF file
            exporter.exportReport();
            
        } catch (JRException e) {
            e.printStackTrace();
            System.exit(1);
        } catch (Exception e) {
            e.printStackTrace();
            System.exit(1);
        }
    }
}

the error is :

Hi.

The error tells you that the Jasper Reports libraries are missing from your classpath.
I move this thread to our Other Open Source Projects forum, because you jave an issue with iReports, not with JDBC.

You might need to include following jar files in your classpath.
jasperreports-3.0.0.jar or whichever version you wish to include,
commons-beanutils-1.8.0jar or whichever verion you wish to include ,
commons-collections-3.2.jar or whichever verion you wish to include
commons-digester-1.8.jar or whichever verion you wish to include
commons-logging-1.1.1.jar. or whichever verion you wish to include

Just google about it if you want different version. Also if you are using any building tools like ant or maven, you would need to include dependencies in your pom.xml. Following is for the maven. This is just for an example. You might need to amend as per your requirements.

<dependency>
<groupId>jasperreports</groupId>
<artifactId>jasperreports</artifactId>
<version>3.5.3</version>
</dependency>

Best regards.
