This customization isn't possible. If properly constrained, xs:anyType might be mapped to java.lang.Object anyway, but as it is now, you are getting org.w3c.dom.Element, which means that you'll get the XML document tree without any unmarshalling.

Hi Wolfgang,
I am just trying to understand how to handle a variable of type java.lang.Object in a JAXB class. Is it possible to read any content into such a generic variable even if the JAXBContext does not know about the corresponding XML element? For example, suppose a schema is associated with the namespace "foo". It is mapped to a set of JAXB classes. One of these classes contains an attribute of type java.lang.Object. An XML instance document contains an element associated with the namespace "bar" as corresponding property element. Would this element be returned as java.lang.Object by the getter of that class even if the JAXBContext does not know about the namespace "bar"? Or would this require to explicitly bind the xsd:anyType property to DOM using a JAXB binding declaration? Cheers, Claus Von: Wolfgang Laun [mailto:wolfgang.laun@...] Gesendet: Freitag, 6.

Hi Wolfgang, Sort of, yes. There are variations, depending on the information provided by the XML document. I'm assuming an element which would have the schema type xs:anyType. If there is no information, you'll get the document element (subtree) as a org.w3c.dom.Element. If the element provides information about its type, e.g. <elemAnyType xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance" xmlns:xs="http://www.w3.org/2001/XMLSchema" xsi:type="xs:int">10</elemAnyType> and JAXB knows how to handle this schema type, it will be unmarshalled into an object of the corresponding Java type. For example, suppose a schema is associated with the namespace "foo". It is A schema "wildcard" (e,g,, <xs:any/>) would result in a Java field Object any, annotated with @XmlanyElement, and the actual type would again be org.w3c.dom.Element. The namespace is arbitrary. This object can be analyzed using the DOM API, but it might also be passed to some (other) unmarshaller, to be created from a suitable context. -W Cheers, |

Hi,
I am attaching both the xsd and the xjb file is there any resolution for these coz if i don't customize the xsd then it generates Class Primary key with getters of or and setters of org.w3c.dom.Element . bindings.xjb |

The given XML schema is so designed as to permit you to have arbitrary elements and attributes as children of the primaryKey element. It is up to the application using this OSS framework to provide these elements and attributes in a form that can be marshalled, and to provide a way to unmarshal the application specific XML data.
If you unmarshal an XML data file conforming to this XML schema, the getter getPrimaryKey gives you a ManagedEntityKey.PrimaryKey key object. For simplicity's sake, let's say that this is supposed to contain a single subelement, to be retrieved from the Element[] returned by key.getAny(). In some given application context, one would know what to expect, i.e., what is represented by this XML document tree. And there should be - perhaps from another XML schema or written by hand - a set of Java classes representing this XML tree. Then it's possible to create another JAXBContext, obtain an Unmarshaller from it, and call u.unmarshal( elem ). - Inspecting the Element object's properties such as getLocalName() and getNamespaceURI() would permit you to distinguish between different types acting as key elements. For marshalling, the reverse process is used. -W On Sun, Nov 8, 2009 at 5:45 PM, indra_4011 <indra4011@...> wrote:

Sorry it did not worked with following xml attached , and the follwing code snippet JAXBContext jc = JAXBContext.newInstance("org.ossj.xml.ordermanagement.v1_0"); Unmarshaller u = jc.createUnmarshaller(); File f = new File("Resource.xml") CreateAndStartRequestByValueResponse element = (CreateAndStartRequestByValueResponse) u.unmarshal(f); System.out.println("ApplicationDN is : "+element.getRequestKey().getApplicationDN()); System.out.println("Type is : "+element.getRequestKey().getType()); JAXBContext jc1 = JAXBContext.newInstance("org.ossj.xml.common.v1_5"); Unmarshaller u1 = jc1.createUnmarshaller(); u1.unmarshal((Element)element.getRequestKey().getPrimaryKey().getAny(0)); Resource.xml |

If the key is a simple (String) type, then why does the XML Schema
