I have been looking across the site searching for a examples on how to implement Unmarshalling using the annotation @XMLSchema on the package-info.java file.
My understanding is that the theory suppose to be really simple. However, after look at the following links I still don't figure our why the annotation is not working.
- Links that I used for reference:
- http://blog.bdoughan.com/2010/08/jaxb-namespaces.html
- JAXB XmlSchema.xmlns (in package-info.java) ignored by marshaller
- @xmlschema jaxb package-info.java compilation error -http://blog.bdoughan.com/2012/07/jaxb-and-root-elements.html
Here is the code:
package-info.java:
@XmlSchema(
namespace="http://test.org/url1",
elementFormDefault = XmlNsForm.QUALIFIED,
attributeFormDefault = javax.xml.bind.annotation.XmlNsForm.UNQUALIFIED,
xmlns={
@XmlNs(prefix="ns6", namespaceURI="http://test.org/url6"),
@XmlNs(prefix="ns5", namespaceURI="http://test.org/url5"),
@XmlNs(prefix="ns7", namespaceURI="http://test.org/url7"),
@XmlNs(prefix="ns1", namespaceURI="http://test.org/url1"),
@XmlNs(prefix="ns3", namespaceURI="http://test.org/url3"),
@XmlNs(prefix="ns2", namespaceURI="http://test.org/url2"),
@XmlNs( prefix="ns4", namespaceURI="http://test.org/url4"),
}
)
package simpleJAXB;
import javax.xml.bind.annotation.*;
The XML used as input:
<?xml version="1.0" encoding="UTF-8"?>
<ns6:RequestShort
xmlns:ns2="http://test.org/url2"
xmlns:ns1="http://test.org/url1"
xmlns:ns4="http://test.org/url4"
xmlns:ns3="http://test.org/url3"
xmlns:ns5="http://test.org/url5"
xmlns:ns6="http://test.org/url6"
xmlns:ns7="http://test.org/url7">
<ns3:IndividualRequestShort>
<ns2:Person>Name1</ns2:Person>
<ns2:Title>TEST</ns2:Title>
</ns3:IndividualRequestShort>
<ns3:IndividualRequestShort>
<ns2:Person>Name2</ns2:Person>
<ns2:Title>TEST2</ns2:Title>
</ns3:IndividualRequestShort>
</ns6:RequestShort>
Here are the classes as well:
RequestShort:
package simpleJAXB;
import java.util.ArrayList;
import javax.xml.bind.annotation.XmlElement;
import javax.xml.bind.annotation.XmlRootElement;
@XmlRootElement ( name = "RequestShort")
public class RequestShort {
ArrayList<IndividualRequestShort> individualRequestListShort;
public RequestShort(){}
@XmlElement(name = "IndividualRequestShort", type=IndividualRequestShort.class)
public ArrayList<IndividualRequestShort> getIndividualRequestListShort() {
return individualRequestListShort;
}
public void setIndividualRequestListShort(
ArrayList<IndividualRequestShort> individualRequestList) {
this.individualRequestListShort = individualRequestList;
}
}
IndividualRequestShort:
package simpleJAXB;
import javax.xml.bind.annotation.XmlElement;
import javax.xml.bind.annotation.XmlRootElement;
@XmlRootElement (name= "IndividualRequestShort")
public class IndividualRequestShort {
String title;
String person;
public IndividualRequestShort(){}
@XmlElement(name = "Title")
public String getTitle() {
return title;
}
public void setTitle(String title) {
this.title = title;
}
@XmlElement(name = "Person")
public String getPerson() {
return person;
}
public void setPerson(String person) {
this.person = person;
}
Finally, the main void method is :
try{
File file = new File("XML_test.xml");
JAXBContext jaxbContext = JAXBContext.newInstance(RequestShort.class);
Unmarshaller jaxbUnmarshaller = jaxbContext.createUnmarshaller();
RequestShort requestShort = (RequestShort) jaxbUnmarshaller.unmarshal(file);
ArrayList<IndividualRequestShort> contentRequests = new ArrayList<IndividualRequestShort>();
contentRequests = requestShort.getIndividualRequestListShort();
if(contentRequests != null){
Iterator<IndividualRequestShort> requestsIterator = contentRequests.iterator();
IndividualRequestShort temp = null;
while (requestsIterator.hasNext()) {
temp = (IndividualRequestShort)requestsIterator.next();
System.out.println("Data: " + temp.getTitle() + temp.getPerson());
}
} catch (Exception e) {
System.out.println(e.toString() + " " + e.getStackTrace().toString());
}
return null;
}
I have been able to actually parse the xml on the xmlelment and xmlrootelement with the namespace option. However, when I am trying to put the xmlschema annotation, as I show above, I receive the following error:

Do I am missing something here? Can you give me a hint ?
Thank you in advance!
PS: Sorry I am asking something so simple, but I am learning this JAXB framework.
