How to export JasperReport to HTML?

Question

I have created one .jasper file for my project. I am getting an output in JasperViewer window, but instead of that I want to see it in HTML output form. How can I d

Answer 1

The following code will generate a HTML report:

private DataSource jasperDataSource;
private String jasperReportDir;

public void generateHtmlReport(String reportPath, String reportCode, String outputLocation,
                               Map params) throws Exception
{

    Connection connection=null;
    try
    {
        connection = jasperDataSource.getConnection();

        JasperReport  jasperReport = (JasperReport) JRLoader.loadObject(jasperReportDir + "/" + reportPath + "/" + reportCode + ".jasper");

        params.put(JRParameter.REPORT_FILE_RESOLVER, new SimpleFileResolver(new File(jasperReportDir + "/" + reportPath)));

        JasperPrint jasperPrint = JasperFillManager.fillReport(jasperReport, params, connection);

        JasperExportManager.exportReportToHtmlFile(jasperPrint,outputLocation +reportCode+".html");

    }
    finally
    {
        if (connection!=null)
        {
            connection.close();
        }
    }
}

Exports the generated report object into HTML format, placing the result into the second file parameter.

The images are placed as distinct files inside a directory having the same name as the HTML destination file, plus the "_files" suffix.
