It's not only a single HTML file, but at least it requires a 1x1 transparent gif used for decorating.

Running standalone Glassfish v3 client as Eclipse plugin
It's not a good idea to export reports to HTML files because of portability and printing issues.

Share interface classes using the same classloader on J2EE/Weblogic 10, without using the system classpath
You can however show HTML reports inside your webserver (which is very commone) using that sample code.

The following code will generate a HTML report:.
private DataSource jasperDataSource; private String jasperReportDir;  public void generateHtmlReport(String reportPath, String reportCode, String outputLocation,                                Map<String, Object> 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.
