I'm using ITextRenderer() method to convert an xhtml code to pdf in java.
This is my code:
ITextRenderer renderer = new ITextRenderer();
renderer.setDocumentFromString(XHTML.toString());
renderer.layout();
final ByteArrayOutputStream baos = new ByteArrayOutputStream();
try {
renderer.createPDF(baos);
} catch (DocumentException e) {
baos.close();
setErrorMessage(response, 500, "Internal Server Error", "Could not create the PDF version of the patient summary.");
return;
}
//convert PDF to base64
String base64PDF = Base64.encodeBytes(baos.toByteArray());
baos.close();
My XMTML.toString() contains the following:
<html xmlns="http://www.w3.org/1999/xhtml">
<head>
<meta http-equiv="Content-Type" content="text/html; charset=utf-8"></meta>
<style>
*{
font-family: Arial;
}
table {
width:100%;
}
table, th, td {
border: 1px solid black;
border-collapse: collapse;
}
th, td {
padding: 5px;
text-align: left;
}
table th {
background-color: #77f;
color: white;
}
</style>
</head>
<body><h1>Patient Summary</h1><hr></hr><table><thead><tr><th colspan="2">Demographics</th></tr></thead><tbody><tr><td>Full Name</td><td>George Georgiou</td></tr><tr><td>Date of

ID="allergy.1.onset">2017-07-04</td></tr></tbody></table>
Unfortunately, the created pdf file is empty. When I use the XHMTL code to an online converted to convert it to a pdf files, it's converted successfully.
Can you help me? Thank you in advance!
I found the solution.
My xhtml file should contain <!DOCTYPE html PUBLIC "-//W3C//DTD XHTML 1.0 Strict//EN" "DTD/xhtml1-strict.dtd"> and also a <title> section.
My complete xhtml file is the following:
<!DOCTYPE html
PUBLIC "-//W3C//DTD XHTML 1.0 Strict//EN"
"DTD/xhtml1-strict.dtd">
<html xmlns="http://www.w3.org/1999/xhtml">
<head>
<title>Patient Summary PDF</title>
<meta http-equiv="Content-Type" content="text/html; charset=utf-8" />
<style>
{
font-family: Arial;
}
table {
width:100%;
}
table, th, td {
border: 1px solid black;
border-collapse: collapse;
}
th, td {
padding: 5px;
text-align: left;
}
table th {
background-color: #77f;
color: white;
}
</style>
</head>
<body><h1>Patient Summary</h1><table><thead><tr><th colspan="2">Demographics</th></tr></thead><tbody><tr><td>Full Name</td><td>George Georgiou</td></tr><tr><td>Date of Birth</td><td>1990-01-01</td></tr><tr><td>Gender</td><td>Male</td></tr><tr><td>Address</td><td>31 Agiou Marona, 1010, Lefkosia, CY</td></tr></tbody></table><h3>Allergies</h3><table><thead><tr><th>Reaction Type</th><th>Clinical Manifestation</th><th>Agent</th><th>Onset Date</th></tr></thead><tbody><tr ID="allergy.1"><td ID="allergy.1.type">Panadol</td><td ID="allergy.1.manifestation">Dyspnoea</td><td ID="allergy.1.agent">Penicillamine and similar agents</td><td ID="allergy.1.onset">2017-07-04</td></tr></tbody></table></body></html>
I had to add three extra jar files: (a) core-renderer.jar, (b) core-renderer-minimal.jar and (c) xml-apis-xerces-2.9.1.jar.
It's important to mention all these work only with iText-2.0.8.jar file.
Also I had to import import com.lowagie.text.DocumentException; and import org.xhtmlrenderer.pdf.ITextRenderer;
