XML to JAVA with @XmlType instead of @XmlRootElement

import javax.xml.bind.JAXBContext;
import javax.xml.bind.Unmarshaller;

...

private AssessResponse loadOpaResponseFromXmlFile(String file) throws Exception {
    JAXBContext jaxbContext = JAXBContext.newInstance(AssessResponse.class);
    InputStream is = getClass().getResourceAsStream(file);
    Unmarshaller unmarshaller = jaxbContext.createUnmarshaller();
    return unmarshaller.unmarshal(new StreamSource(is), AssessResponse.class).getValue();
}

@XmlAccessorType(XmlAccessType.FIELD)
@XmlType(name = "AssessResponse", propOrder = {
    "versionInfo",
    "events",
    "globalInstance"})
public class AssessResponse
    implements Serializable

Method to preetyPrint Document in java

public static void write(org.dom4j.Document document) {
        try {
            // Pretty print the document to System.out
            org.dom4j.io.OutputFormat format = org.dom4j.io.OutputFormat.createPrettyPrint();
            org.dom4j.io.XMLWriter writer = new org.dom4j.io.XMLWriter(new FileWriter("C:\\output.xml"), format);
            writer.write(document);
            writer.close();
        } catch (IOException e) {
            // TODO Auto-generated catch block
            e.printStackTrace();
        }
    }

Nice framework for testing (equals) xml: XmlUnit

XSL Warning in Eclipse

To make folling error

No grammar constraints (DTD or XML schema) detected for the document.

go away, add folling:

<?xml version="1.0" encoding="UTF-8"?>

<!DOCTYPE xsl:stylesheet [<!ENTITY bullet "•"> <!ENTITY nbsp " ">]>

Change • to & #x2022;
and space to & #xa0; with no space between & and #

Parese XML without DTD validation

Use the Saxparser...
