parse - Problemas con JAXB, Marshal,-incapaz de ordenar tipo "java.lang.String"

string xml to object java

Question

tengo un problema, genere las clases usando un esquema xsd con xjc. cuando ejecuto la operación Marshal recibo el siguiente error:

[com.sun.istack.internal.SAXException2: unable to marshal type "java.lang.String" as an element because it is missing an @XmlRootElement annotation] at com.sun.xml.internal.bind.v2.runtime.MarshallerImpl.write(Unknown Source) at com.sun.xml.internal.bind.v2.runtime.MarshallerImpl.marshal(Unknown Source) at javax.xml.bind.helpers.AbstractMarshallerImpl.marshal(Unknown Source) at prova.StampGenericXML.staticStampGenericXML(StampGenericXML.java:42) at prova.TestLauncher.main(TestLauncher.java:199) Caused by: com.sun.istack.internal.SAXException2: unable to marshal type "java.lang.String" as an element because it is missing an @XmlRootElement annotation at com.sun.xml.internal.bind.v2.runtime.XMLSerializer.reportError(Unknown Source) at com.sun.xml.internal.bind.v2.runtime.LeafBeanInfoImpl.serializeRoot(Unknown Source) at com.sun.xml.internal.bind.v2.runtime.property.SingleReferenceNodeProperty.serializeBody(Unknown Source) at com.sun.xml.internal.bind.v2.runtime.ClassBeanInfoImpl.serializeBody(Unknown Source) at com.sun.xml.internal.bind.v2.runtime.XMLSerializer.childAsXsiType(Unknown Source) at com.sun.xml.internal.bind.v2.runtime.property.SingleElementNodeProperty.serializeBody(Unknown Source) at com.sun.xml.internal.bind.v2.runtime.ClassBeanInfoImpl.serializeBody(Unknown Source) at com.sun.xml.internal.bind.v2.runtime.XMLSerializer.childAsXsiType(Unknown Source) at com.sun.xml.internal.bind.v2.runtime.property.SingleElementNodeProperty.serializeBody(Unknown Source) at com.sun.xml.internal.bind.v2.runtime.ClassBeanInfoImpl.serializeBody(Unknown Source) at com.sun.xml.internal.bind.v2.runtime.XMLSerializer.childAsXsiType(Unknown Source) at com.sun.xml.internal.bind.v2.runtime.property.ArrayElementNodeProperty.serializeItem(Unknown Source) at com.sun.xml.internal.bind.v2.runtime.property.ArrayElementProperty.serializeListBody(Unknown Source) at com.sun.xml.internal.bind.v2.runtime.property.ArrayERProperty.serializeBody(Unknown Source) at com.sun.xml.internal.bind.v2.runtime.ClassBeanInfoImpl.serializeBody(Unknown Source) at com.sun.xml.internal.bind.v2.runtime.XMLSerializer.childAsXsiType(Unknown Source) at com.sun.xml.internal.bind.v2.runtime.property.SingleElementNodeProperty.serializeBody(Unknown Source) at com.sun.xml.internal.bind.v2.runtime.ClassBeanInfoImpl.serializeBody(Unknown Source) at com.sun.xml.internal.bind.v2.runtime.XMLSerializer.childAsXsiType(Unknown Source) at com.sun.xml.internal.bind.v2.runtime.property.ArrayElementNodeProperty.serializeItem(Unknown Source) at com.sun.xml.internal.bind.v2.runtime.property.ArrayElementProperty.serializeListBody(Unknown Source) at com.sun.xml.internal.bind.v2.runtime.property.ArrayERProperty.serializeBody(Unknown Source) at com.sun.xml.internal.bind.v2.runtime.ClassBeanInfoImpl.serializeBody(Unknown Source) at com.sun.xml.internal.bind.v2.runtime.XMLSerializer.childAsXsiType(Unknown Source) at com.sun.xml.internal.bind.v2.runtime.property.SingleElementNodeProperty.serializeBody(Unknown Source) at com.sun.xml.internal.bind.v2.runtime.ClassBeanInfoImpl.serializeBody(Unknown Source) at com.sun.xml.internal.bind.v2.runtime.XMLSerializer.childAsXsiType(Unknown Source) at com.sun.xml.internal.bind.v2.runtime.property.SingleElementNodeProperty.serializeBody(Unknown Source) at com.sun.xml.internal.bind.v2.runtime.ClassBeanInfoImpl.serializeBody(Unknown Source) at com.sun.xml.internal.bind.v2.runtime.XMLSerializer.childAsSoleContent(Unknown Source) at com.sun.xml.internal.bind.v2.runtime.ClassBeanInfoImpl.serializeRoot(Unknown Source) at com.sun.xml.internal.bind.v2.runtime.XMLSerializer.childAsRoot(Unknown Source)

la porción del código xsd es:

<xsd:complexType name="formattedText">
<xsd:annotation>
<xsd:documentation>Formatted text according to parts of XHTML 1.1 </xsd:documentation>
</xsd:annotation>
<xsd:sequence>
<xsd:any namespace="http://www.w3.org/1999/xhtml" processContents="lax"/>
</xsd:sequence>
</xsd:complexType>

la clase FormattedText es:

import javax.xml.bind.annotation.XmlAccessType;
import javax.xml.bind.annotation.XmlAccessorType;
import javax.xml.bind.annotation.XmlAnyElement;
import javax.xml.bind.annotation.XmlType;
import org.w3c.dom.Element;

/ ** * Texto formateado según partes de XHTML 1.1 * *

Clase Java para el tipo complejo de texto formateado. * *

El siguiente fragmento de esquema especifica el contenido esperado contenido dentro de esta clase. * *

* <complexType name="formattedText"> * <complexContent> * <restriction base="{http://www.w3.org/2001/XMLSchema}anyType"> * <sequence> * <any processContents=''lax'' namespace=''http://www.w3.org/1999/xhtml''/> * </sequence> * </restriction> * </complexContent> * </complexType> * * * *

@XmlAccessorType(XmlAccessType.FIELD)
@XmlType(name = "formattedText", propOrder = {
"any"
})
public class FormattedText {
@XmlAnyElement(lax = true)
protected Object any;
/**
* Gets the value of the any property.
*
* @return
* possible object is
* {@link Element }
* {@link Object }
*
*/
public Object getAny() {
return any;
}
/**
* Sets the value of the any property.
*
* @param value
* allowed object is
* {@link Element }
* {@link Object }
*
*/
public void setAny(Object value) {
this.any = value;
}
}

esta es la clase para la operación mariscal

public class StampGenericXML {
static public void staticStampGenericXML(Object objectJAXB, String context) throws ParserConfigurationException, SAXException, TransformerException{
try {
JAXBContext jaxbLocalContext = JAXBContext.newInstance ("org.plcopen.xml.tc6_0201");
Marshaller marshaller = jaxbLocalContext.createMarshaller();
marshaller.setProperty(marshaller.JAXB_FORMATTED_OUTPUT, true);
marshaller.marshal(objectJAXB, System.out);
} catch (JAXBException e1) {
e1.printStackTrace();
}
}

}

Cuando creo un objeto FormattedText:

FormattedText text = new FormattedText();
text.setAny("table");

y ejecutar el proyecto tengo este error. ¿Por qué? por favor, ayúdame. Gracias

Tratar:

text.setAny(new JAXBElement<String>(
new QName("table"), String.class, "tableContent");
