Hello Raman,

I think there’s= nothing out of the box for Tuscany SDOs. I did experiment with Pojo/SDO-co= nversion a while back based on the Eclipse example you cite.

I use a common base c= lass Pojo for all the pojos and customize my jaxb bindings with a <xjc:s= uperclass> annotation in bindings.xjb. This base class

contains toXML() and = fromXML() methods implemented in the usual JAXB way.

A PojoSDOBridge for T= uscany then can be implemented like this:

/**

* Conver= t an SDO to a bean via the shared XML representation.

* <p&= gt;

* Implem= entation note: Does not depend on EclipseLink JAXBContextHelper, only on st= andard JAXB.

* @param= sdo

* @retur= n the bean of the corresponding type

* @throw= s JAXBException

* @throw= s ClassNotFoundException

public static = Pojo toPojo( DataObject sdo ) throws JAXBException, ClassNotFoundException<= /span>

{

SD= OHelper helper =3D SDOHelperFactory.getHelper();

St= ring xml =3D helper.toXML( sdo, null );

Cl= ass<? extends Pojo> clazz =3D Pojo.load( sdo.getType().getURI(), sdo.= getType().getName() );

Po= jo bean =3D Pojo.fromXML( xml, clazz );

re= turn bean;

}

/**

* Conver= t a bean to an SDO via the shared XML representation.

* <p&= gt;

* Implem= entation note: Does not depend on EclipseLink JAXBContextHelper, only on Tu= scany's SDO implementation.

* @param= bean

* @retur= n the SDO of the corresponding type

* @throw= s JAXBException

* @throw= s ClassNotFoundException

public static = DataObject toSDO( Pojo bean ) throws JAXBException, ClassNotFoundException<= /span>

{

St= ring xml =3D bean.toXML();

//= The generated XML contains an xsi:type element, so the XML can be unmarsha= lled to an SDO of that type

XM= LHelper xmlHelper =3D HelperProvider.getDefaultContext().getXMLHelper();

XM= LDocument xmlDoc =3D xmlHelper.load( xml );

Da= taObject sdo =3D xmlDoc.getRootObject();

re= turn sdo;

}

For loading the pojo = class, one must find the FQCN corresponding to the given type and namespace= . That can be a challenge.

XJC does it, but I ha= ven’t had time to figure out how exactly. I came up with a simplifica= tion that works in most cases. I’d be

grateful for a better= suggestion:

/**

* Constr= ucts the fully qualified class name corresponding to the given type's names= pace and name.

* <p&= gt;

* Intend= ed as an analogue to what xjc does.

* @param= namespace must be a valid HTTP-URL. Used to contruct the package name.

* @param= typeName the simple name of a type belonging to the namespace. Corresponds= to the simple class name.

* @retur= n the fully qualified class name

// TODO find a= utility library that does EXACTLY the same as XJC, even for arbitrary URL'= s.

private static= final String fullyQualifiedClassName( String namespace, String typeName )<= /span>

{

UR= L url;

tr= y {

&nb= sp; url =3D new URL( namespace );

}<= /span>

ca= tch( MalformedURLException e ) {

&nb= sp; throw new IllegalStateException( "Namespace must be a valid = URL", e );

}<= /span>

if= ( !url.getProtocol().equals( "http" ) ) {

&nb= sp; throw new IllegalArgumentException( "Namespace must be an HT= TP-URL, not " + url );

}<= /span>

St= ring packagePrefix =3D join( reverse( url.getHost().split( "\\." = ) ), '.' );

St= ring packageSuffix =3D url.getPath().replaceAll( "/", ".&quo= t; );

St= ring className =3D packagePrefix + packageSuffix + "." &#= 43; typeName;

re= turn className;

}

Hope that gets you st= arted. Perhaps something like this would be worth including in a Tuscany ut= ility class?

Best Regards,<= /p>

Subject: JAXBHelperContext, the POJO/SDO bridge for Tuscany SDO

Hi,

Is there = POJO/SDO bridge for Tuscany SDO API like one discussed at http://wi= ki.eclipse.org/EclipseLink/Examples/SDO/JAXB.

We use SDO as data model for services, but some peop= le have problem with dealing dynamic DataObjects. So, I am looking for conv= ersion from static DataObject to dynamic DataObject or POJO to SDO.

Regards
