command line report generation

[darthwader100]

Are there any command-line frontends available to JasperReports?

 

I have designed a report using iReport. Now I want to do something simple in my Perl cgi script like calling a command-line program with the report definition as a parameter and get a pdf in return that I can present to the web user.

 

I am new to JasperReports and any help is appreciated.

Are you familiar with the java language at all? Its a fairly straightforward bit of code if you are.

 

 

The only tricky part is getting the right data source depending on the requirements of your report. Here is a sample program I would use, where the only thing that is left to change is the datasource:

 

Code:

import net.sf.jasperreports.engine.JREmptyDataSource;
import net.sf.jasperreports.engine.JRException;
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;

public class JavaReportRunner {
	
	//args[0] - full path to .jrxml file
	//args[1] - full path to output pdf file
	public static void main(String[] args) {
		 JasperReport jasperReport;
		 JasperPrint jasperPrint;
		    try
		    {
			    	
		      jasperReport = JasperCompileManager.compileReport(args[0]);
		      
		      Map customParameters = new HashMap(); 

				  jasperPrint = JasperFillManager.fillReport(
						  		jasperReport, customParameters, new JREmptyDataSource());
				  
		      JasperExportManager.exportReportToPdfFile(
		          jasperPrint, args[1]);
		      
		    }
		    catch (JRException e)
		    {
			  e.printStackTrace();
		    }	
		
	}
}

 

you would then compile this code to a java .class file and call this file using the appropriate java commands.

Came across this post when I had a similar need and wrote a simple java command line utility like the above to generate PDF or HTML to disk and optionally email. It can be downloaded at http://www.gtportalbase.com/opensource

 

At time of writing, only tested on two computers, so anyone who uses it please email me if you get any problems.
