Exporting to HTML generates the following:
<html>
<head>
<title></title>
<meta content="text/html; charset=UTF-8" http-equiv="Content-Type">
<style type="text/css">
a {text-decoration: none}
</style>
</head>
<body vlink="#000000" text="#000000" link="#000000" alink="#000000">
<table width="100%" border="0" cellspacing="0" cellpadding="0">
<tbody>
<tr>
<td width="50%"> </td>
<td align="center">
<!-- The report -->
</td>
<td width="50%"> </td>
</tr>
</tbody>
</table>
</body>
</html>
The report is centered on the page, but should be left-aligned.
Using JRHtmlExporter's HTML_HEADER parameter looked promising, but the classes have been deprecated. This was the solution:
JRHtmlExporter exporter = new JRHtmlExporter();
exporter.setParameter(JRExporterParameter.JASPER_PRINT, jasperPrint);
exporter.setParameter(JRHtmlExporterParameter.HTML_HEADER,
"<html>"+
"<head>"+
" <title></title>"+
" <meta http-equiv="Content-Type" content="text/html; charset=UTF-8"/>"+
" <link rel=\"stylesheet\" type=\"text/css\" href=\"css/jasper.css\" />"+
" <style type="text/css">"+
" a {text-decoration: none}"+
" </style>"+
"</head>"+
"<body text="#000000" link="#000000" alink="#000000" vlink="#000000">"+
"<table width="100%" cellpadding="0" cellspacing="0" border="0">"+
"<tr><td width="50%"> </td><td align="center">");
exporter.exportReport();
Now I have to use the net.sf.jasperreports.export.HtmlExporter and net.sf.jasperreports.export.SimpleHtmlReportConfiguration classes, in this way:
HtmlExporter exporterHTML = new HtmlExporter();
SimpleExporterInput exporterInput = new SimpleExporterInput(report.getJasperPrint());
exporterHTML.setExporterInput(exporterInput);
HtmlExporterOutput exporterOutput = new SimpleHtmlExporterOutput(out);
exporterHTML.setExporterOutput(exporterOutput );
SimpleHtmlReportConfiguration reportExportConfiguration = new SimpleHtmlReportConfiguration();
reportExportConfiguration.setWhitePageBackground(false);
reportExportConfiguration.setRemoveEmptySpaceBetweenRows(true);
exporterHTML.setConfiguration(reportExportConfiguration);
exporterHTML.exportReport();
How would you fix this?
The HTML_HEADER parameter of JRHtmlExporterParameter was replaced with:
For example:
public byte[] exportHtml(final JasperPrint print) {
final Exporter exporter = new HtmlExporter();
final ByteArrayOutputStream out = new ByteArrayOutputStream();
exporter.setConfiguration(createHtmlConfiguration());
exporter.setExporterOutput(new SimpleHtmlExporterOutput(out));
exporter.setExporterInput(new SimpleExporterInput(print));
exporter.exportReport();
return out.toByteArray();
}
private HtmlExporterConfiguration createHtmlConfiguration()
throws IOException {
SimpleHtmlExporterConfiguration shec
= new SimpleHtmlExporterConfiguration();
shec.setHtmlHeader(getHtmlHeader());
shec.setHtmlFooter(getHtmlFooter());
return shec;
}
private String getHtmlHeader() {
StringBuffer sb = new StringBuffer();
sb.append("<html>");
sb.append("<head>");
sb.append(" <title></title>");
sb.append(" <meta http-equiv=\"Content-Type\" content=\"text/html; charset=UTF-8\"/>");
sb.append(" <style type=\"text/css\">");
sb.append(" a {text-decoration: none}");
sb.append(" </style>");
sb.append("</head>");
sb.append("<body text=\"#000000\" link=\"#000000\" alink=\"#000000\" vlink=\"#000000\">");
sb.append("<table width=\"100%\" cellpadding=\"0\" cellspacing=\"0\" border=\"0\">");
sb.append("<tr><td align=\"left\">");
return sb.toString();
}
private String getHtmlFooter() {
// Close the opening tags from getHtmlHeader()...
}
Even better would be to use external resources (such as a database, file, or web page) for the HTML content, rather than hard-coded strings.
