    <p>Modifying generated java classes, I don't agree. Not allowing all possible xsd format, I don't agree.</p> <p>Thanx to all your explanations an links, this is the code I've have written so as to take care of both cases, using Annotation Introspection. It works for output as well as input, and is <em>(in my taste)</em> more generic:</p> <pre><code>public class JaxbWrapper { private static boolean isXmlRootElement(Class classT){ Annotation[] annotations = classT.getAnnotations(); for(Annotation annotation : annotations){ if(annotation instanceof XmlRootElement){ return true; } } return false; } public static Object unmarshall(Class classObjectFactory, Class classObject, XMLStreamReader xmlStreamReader){ Package pack = classObjectFactory.getPackage(); String strPackageName = pack.getName(); Object returnObject = null; try { JAXBContext jc = JAXBContext.newInstance(strPackageName, classObjectFactory.getClassLoader()); Unmarshaller unmarshaller = jc.createUnmarshaller(); returnObject = unmarshaller.unmarshal( xmlStreamReader ); boolean bIsRootedElement = isXmlRootElement(classObject); if(!bIsRootedElement) { JAXBElement jaxbElement = (JAXBElement) returnObject; returnObject = jaxbElement.getValue(); } } catch (JAXBException e) { /*...*/ } return returnObject; } private static void writeToXml(Class classObjectFactory, Object obj, XMLStreamWriter xmlStreamWriter){ Package pack = classObjectFactory.getPackage(); String strPackageName = pack.getName(); try { JAXBContext jc = JAXBContext.newInstance(strPackageName, classObjectFactory.getClassLoader()); Marshaller marshaller = jc.createMarshaller(); marshaller.marshal(obj, xmlStreamWriter); } catch(JAXBException e) { /*...*/ } } public static String marshall(Class classObjectFactory, Class classObject, Object obj){ Object objectToMarshall = obj; boolean bIsRootedElement = isXmlRootElement(classObject); if(!bIsRootedElement) { Package pack = classObjectFactory.getPackage(); String strPackageName = pack.getName(); String strClassName = classObject.getName(); QName qName = new QName(strPackageName, strClassName); JAXBElement jaxbElement = new JAXBElement(qName, classObject, null, obj); objectToMarshall = jaxbElement; } StringWriter sw = new StringWriter(); XMLOutputFactory xmlOutputFactory = XMLOutputFactory.newInstance(); XMLStreamWriter xmlStreamWriter = null; try { xmlStreamWriter = xmlOutputFactory.createXMLStreamWriter(sw); writeToXml(classObjectFactory, objectToMarshall, xmlStreamWriter); xmlStreamWriter.flush(); xmlStreamWriter.close(); } catch (XMLStreamException e) { /*...*/ } return sw.toString(); } } </code></pre>

A row detail

Detail views are divided into sections. All the information in the data section comes from columns in the selected row. The other sections display data from other, related rows.

Related data can be related in a to-one or a to-many fashion. Captions of data related in a to-many fashion link to a list view showing a filtered view of the table.

Try moving around until you find a non-empty to-many entry and click on the label to get to one. You can move back to the root by clicking on the database name in the header.
