jaxb xjc download (6)
Puede encontrar muchas preguntas como esta en este sitio, pero ninguna ha resuelto mi problema.
Este es mi XML:
<?xml version=''1.0'' encoding=''UTF-8'' standalone=''yes''?>
<lookupInstances xmlns=''http://www.pqr.com/awd/rest/v1'' name=''LKIMGR''>
<lookupParameters>
<lookupParameter name=''businessArea''>PQAA</lookupParameter>
<lookupParameter name=''MEMBERNUMBER''>ANTHONY1900</lookupParameter>
</lookupParameters>
</lookupInstances>
He creado la clase Jaxb usando el compilador XJC y el archivo creado es como:

Código Unmarshal:

try {

Unmarshaller u = jc.createUnmarshaller();
StringBuffer xmlStr = new StringBuffer( xmlReq );
StringReader strReader = new StringReader( xmlStr.toString() );
StreamSource strSource = new StreamSource(strReader);
Object o = u.unmarshal( strSource );
instances = (LookupInstances)o;
} catch (JAXBException e) {
e.printStackTrace();
}
return instances;
}
Tengo este error
javax.xml.bind.UnmarshalException: unexpected element (uri:"http://www.pqr.com/awd/rest/v1", local:"lookupInstances"). Expected elements are <{}lookupInstances>
Por favor ayuda.
A continuación hay información que debería ayudar:
XML
A continuación se muestra una parte de su XML. Una cosa a tener en cuenta es el atributo xmlns . Este es un atributo especial y se refiere a la calificación de espacio de nombres dentro del documento XML.
<lookupInstances xmlns=''http://www.pqr.com/awd/rest/v1'' name=''LKIMGR''>
<lookupParameters/>
</lookupInstances>
A continuación se muestra otra versión del XML con la misma calificación de espacio de nombres:
<abc:lookupInstances xmlns:abc=''http://www.pqr.com/awd/rest/v1'' name=''LKIMGR''>
<abc:lookupParameters/>
</abc:lookupInstances>
Cuando elimina el atributo xmlns la calificación de espacio de nombres se elimina. El documento a continuación no es equivalente a los dos anteriores.
<lookupInstances name=''LKIMGR''>
<lookupParameters/>
</lookupInstances>
Tu error
javax.xml.bind.UnmarshalException: unexpected element (uri:"http://www.pqr.com/awd/rest/v1", local:"lookupInstances"). Expected elements are <{}lookupInstances>
Este error indica que no ha asignado correctamente la calificación de espacio de nombres.
Mapeo de la calificación del espacio de nombres en JAXB
La calificación del espacio de nombres en JAXB se realiza utilizando la anotación @XmlSchema nivel de paquete. Las anotaciones a nivel de paquete van en package-info.java . A continuación se muestra la fuente completa de esta clase. Si ya tiene un archivo fuente package-info.java , asegúrese de que esté siendo compilado y empaquetado con el resto de sus clases.
@XmlSchema(
namespace = "http://www.pqr.com/awd/rest/v1",
elementFormDefault = XmlNsForm.QUALIFIED)
package your_package;
import javax.xml.bind.annotation.XmlNsForm;
import javax.xml.bind.annotation.XmlSchema;
Esquema XML
Si está generando su modelo a partir de un esquema XML, asegúrese de que la calificación del espacio de nombres esté correctamente definida allí. Se verá como
<?xml version="1.0" encoding="UTF-8"?>
<xs:schema
xmlns:xs="http://www.w3.org/2001/XMLSchema"
targetNamespace="http://www.pqr.com/awd/rest/v1"
xmlns="http://www.pqr.com/awd/rest/v1"
elementFormDefault="qualified">
</xs:schema>
Cambio
@XmlRootElement(name = "lookupInstances")
a
@XmlRootElement( namespace = "http://www.pqr.com/awd/rest/v1", name = "lookupInstances")
En primer lugar tienes que comprobar el archivo XML de entrada. Asegúrese de que el XML de entrada debe tener el mismo elemento raíz que su archivo XSD (que ha utilizado para crear las clases de JAXb). Por favor, intente con XML, funcionará bien :)
<?xml version=''1.0'' encoding=''UTF-8'' standalone=''yes''?>
<lookupInstances name=''LKIMGR''>
<lookupParameters>
<lookupParameter name=''businessArea''>PQAA</lookupParameter>
<lookupParameter name=''MEMBERNUMBER''>ANTHONY1900</lookupParameter>
</lookupParameters>
</lookupInstances>
He cambiado la clase jaxb cambiando el xsd y está funcionando ahora.

Parece que la clase creada por JAXB no contiene la información del espacio de nombres:
@XmlType(name = "", propOrder = {
"lookupParameters"
})
Sospecho que causa este error, simplemente porque no espera ningún espacio de nombres:
javax.xml.bind.UnmarshalException: elemento inesperado (uri: " pqr.com/awd/rest/v1 ", local: "lookupInstances"). Los elementos esperados son <{}Instancias de búsqueda>
No estoy seguro de por qué la clase generada carece de esta información, pero comenzaría agregándola manualmente para verificar que este es el problema:
@XmlType(name = "", namespace= "http://www.pqr.com/awd/rest/v1", propOrder = {
"lookupParameters"
})
@XmlSchema(namespace = "http://www.pqr.com/awd/rest/v1",
elementFormDefault = XmlNsForm.QUALIFIED) package your_package;
import javax.xml.bind.annotation.XmlNsForm;
import javax.xml.bind.annotation.XmlSchema;
Esta parte es muy importante para las clases generadas por JAXB, especialmente el elementFormDefault = XmlNsForm.QUALIFIED no agregará automáticamente elementFormDefault = XmlNsForm.QUALIFIED .
Gracias Blaise, tu respuesta me ayudó.
