Display XML in jsp file using Spring MVC

I need to display an XML file in jsp. The code should go to a particular location and read xml and then show it in a jsp.

I have done the file reading part but when I try to show that in jsp I am getting error. I tried different ways, like escaping char, setting content type, but every time I get a different error.

One of them is -

XML Parsing Error: no element found Location:

http://localhost:8080/viewXmlFile

Line Number 8, Column 12:

Is there any way I can show the XML file in jsp? I am using Spring MVC.

@RequestMapping(value = "/viewXmlFile", method = RequestMethod.GET)
public ModelAndView viewXmlFile(HttpServletRequest request, HttpServletResponse response) {
    String path = //sec15/folder/myXmlFile.xml;

    StringBuffer data = new StringBuffer();
    try(BufferedReader reader = Files.newBufferedReader(Paths.get(path), StandardCharsets.UTF_8);) {
        List<String> collect = reader.lines().collect(Collectors.toList());

        for (String line : collect) {
            data.append(line + CommonConstants.FILE_NEXT_LINE);
        }
    } catch (Exception e) {
    }

    ModelAndView model = new ModelAndView("viewXmlFile");
    model.addObject("xmlData", data.toString());
    return model;
}

This is the JSP file-

<%@page contentType="text/html" pageEncoding="UTF-8"%>
<%@ taglib uri="http://java.sun.com/jsp/jstl/core" prefix="c"%>
<html>
<body>
<pre>
    <c:out value="${xmlData}" />
</pre>
</body>
</html>

This is the XML, I am trying to show-

<?xml version="1.0" encoding="UTF-8" standalone="yes"?>
<ns14:Appearance xmlns:ns2="http://www.example.com/ObjectMetadata/9.0" xmlns:ns3="http://www.example.com/TransactionMetadata/9.0" xmlns:ns14="http://www.example.com/Appearance/2.56">
    <ns3:TransactionMetadata>
        <SourceSystem>Alpha</SourceSystem>
        <TransactionType>Appearance</TransactionType>
        <UniqueTransactionId>8d797d156487</UniqueTransactionId>
        <TransactionDateTime>2017-05-23T03:04:48.025+02:00</TransactionDateTime>
    </ns3:TransactionMetadata>
    <Appearance>
        <ns2:ObjectMetadata>
            <ActionType>Update</ActionType>
            <BusinessObjectName>Appearance</BusinessObjectName>
        </ns2:ObjectMetadata>
        <AppearanceUID>A500003410</AppearanceUID>
        <AppearanceNumber>001</AppearanceNumber>
        <AppearanceName>1495501</AppearanceName>
        <CreationDate>2017-05-23T03:04:37+02:00</CreationDate>
        <ModifiedDate>2017-05-23T03:04:38+02:00</ModifiedDate>
    </Appearance>
</ns14:Appearance>

After changing the jsp file I am able to view the XML on jsp.

This is the code I have in jsp now-

<%@page contentType="text/xml" pageEncoding="UTF-8"%>${xmlData}
