Parsing XML to HTML using XSL in java throwing parsing issue

I have a requirement to convert XML to HTML document. Am trying to convert XML to HTML with the help of XSLT. In my XSLT i have few charaters like é & € while parsing into HTML document its giving below error.

The entity "eacute" was referenced, but not declareded for é.

The entity "euro" was referenced, but not declareded. for €

Please find my XSLT file

<?xml version="1.0"?>
<xsl:stylesheet version="1.0" xmlns:xsl="http://www.w3.org/1999/XSL/Transform">
<xsl:template match="/receipt">
    <html>
        <head>
        </head>
        <body>
            <table style="width: 100%;">
                <tr>
                    <td style="text-align: center; width: 25%;">
                    </td>
                    <td style="font-size: 12px; vertical-align: top; width: 25%;">

                        46-68 Kléber<br/>
                        Tél: +1 <br/>
                        Fax: +1
                    </td>
                    <td style="font-size: 12px; vertical-align: top; width: 25%;">
                        725 € <br />

                    </td>
                    <td style="text-align: center; width: 25%;">Date <xsl:value-of select="date" /></td>
                </tr>
            </table>
        </body>
    </html>
</xsl:template>
</xsl:stylesheet>

Am writting Java code for XML to HTML parsing. Please find my code below.

public static StringWriter getOrderAcknowledgementPDF(JSONObject obj) throws IOException, DocumentException
{

     StringBuilder xml = new StringBuilder();
     String header="<?xml version=\"1.0\" encoding=\"UTF-8\"?>";

            StringBuilder sb = new StringBuilder();
            sb.append(header);
            JSONObject json = new JSONObject(obj.toString());
            xml.append(header);
            xml.append("\n");
            xml.append("<delivery_receipt>");
            xml.append(XML.toString(json));
            xml.append("</delivery_receipt>");


        System.out.println("XML--->"+xml);

        Transformer transformer;
        try {
            transformer = TransformerFactory.newInstance().newTransformer(new StreamSource(new File("D:/Phase2/UAT_Phase/Order_Acknowledgement/template.xsl")));
        } catch (TransformerConfigurationException | TransformerFactoryConfigurationError e1) {
            throw ExceptionUtils.handle((Exception) e1);
        }
        StringWriter sw = new StringWriter();
        try {
            transformer.transform(new StreamSource(new ByteArrayInputStream(xml.toString().getBytes("UTF-8"))), new StreamResult(sw));
        } catch (TransformerException e) {
            throw ExceptionUtils.handle(e);
        }
        return sw;
}


protected void doGet(HttpServletRequest req, HttpServletResponse resp) throws ServletException, IOException {

try {
        String orderid=req.getParameter("item");    
        String reportname = "OrderAcknowledgement"; 
        resp.setHeader("Content-Disposition", "attachment; filename=" + reportname + ".pdf");

        StringWriter result = service.getOrderAcknowledgementPDF(orderid);
        File file = File.createTempFile("Order_Acknowledgement-", ".pdf");
        ITextRenderer renderer = new ITextRenderer();
        try {
            renderer.getFontResolver().addFont("C:/WINDOWS/FONTS/ARIAL.TTF", true);
        } catch (DocumentException e) {
            throw ExceptionUtils.handle(e);
        }
        String fileNameWithPath = "D:/" + "PDF-FromHtmlString.pdf";
        String str=result.toString().replace("<META http-equiv=\"Content-Type\" content=\"text/html; charset=UTF-8\">", "<META http-equiv=\"Content-Type\" content=\"text/html; charset=UTF-8\" />");
         str=str.replace("<br>", "<br />");
        System.out.println("after replacing....-->"+str);
        XMLResource res = XMLResource.load(new StringReader("<html><head><style>@page { size : 45cm 30cm; }</style></head><body>"+str + "</body></html>"));
        resp.setContentType("application/pdf");
        org.w3c.dom.Document doc2 = res.getDocument();
        renderer.setDocument(doc2, "file:/C:/");
        renderer.layout();
        if(fileNameWithPath != null)
        {
              resp.setHeader("Content-Disposition", String.format("attachment; filename=\"%s\"", fileNameWithPath));
        }

        OutputStream browserStream = resp.getOutputStream();
        renderer.createPDF(browserStream);
    }
}

Am getting error in the below line :

 XMLResource res = XMLResource.load(new StringReader("<html><head><style>@page { size : 45cm 30cm; }</style></head><body>"+str + "</body></html>"));

Try to change the XSLT to create XHTML with e.g.

<?xml version="1.0"?>
<xsl:stylesheet version="1.0" xmlns:xsl="http://www.w3.org/1999/XSL/Transform" xmlns="http://www.w3.org/1999/xhtml">
<xsl:output method="xml" indent="yes" omit-xml-declaration="yes"/>
<xsl:template match="/receipt">
    <html>
        <head>
        </head>
        <body>
            <table style="width: 100%;">
                <tr>
                    <td style="text-align: center; width: 25%;">
                    </td>
                    <td style="font-size: 12px; vertical-align: top; width: 25%;">

                        46-68 Kléber<br/>
                        Tél: +1 <br/>
                        Fax: +1
                    </td>
                    <td style="font-size: 12px; vertical-align: top; width: 25%;">
                        725 € <br />

                    </td>
                    <td style="text-align: center; width: 25%;">Date <xsl:value-of select="date" /></td>
                </tr>
            </table>
        </body>
    </html>
</xsl:template>
</xsl:stylesheet>

then instead of using a StringWriter and a StreamResult use a

DOMResult result = new DOMResult();

use that as the transformation result e.g.

transformer.transform(new StreamSource(new ByteArrayInputStream(xml.toString().getBytes("UTF-8"))), result);

and then you can feed Document resultDoc = result.getNode() to your

renderer.setDocument(resultDoc, ...);

That should avoid the problem with entity references, I don't know how the renderer you use works with XHTML so there might be better ways to use that API, but based on the approach you have shown so far my suggestion at least might solve the error you get.
