[J2xb-development] Fwd: J2BX feature request/questions

[Yoav A. <yo...@gm...>]

Hi John,

Thanks for looking at the J2XB library and the integration with Axis2.

About your comments -
1. Injecting comments to the generated XML Schema is a good idea. I will add
it to the J2XB schema generation options. I think about adding a new
annotation that it's content will be added as an XML Schema annotations.

Maybe something like (for single annotations)
*@MoXmlAnnotation(type=documentation, value="...")

*and for multiple annotations
@MoXmlAnnotations( value = {
  *@MoXmlAnnotation(type=documentation, value="...")
  **@MoXmlAnnotation(type=appInfo, value="...")*
})


2. The generation of the Endpoints section in the WSDL is done automatically
by Axis2 - I do not modify the default behavior of Axis2. I believe that
Axis2 has the ability to expose the same service as both.


3. Good idea. I had not tried to do the client side because there are other
solutions that generate the client side from the WSDL, where there are not
good alternative to generate the WSDL from the server code. However, I can
see the logic, in some cases, to have the client use the same POJOs as the
server, using the same annotations. I will add this support soon - you are
actually invited to help if you like.



About the code you wrote -  You got the code almost right. However, because
Axis2 wraps the J2XB XML with a request - response XML element, the
client-side code will be a little more complicated. I will prepare an
example and send another email later this week.

For the code sample you sent, I think you should replace the lines (if I
understand right what you are trying to do)

* XmlAxiomFactory fac = XmlAxiomFactory.getInstance();
MoXmlBeanDescriptor beanDesc = new MoXmlBeanDescriptor(*
*xmlBindingModel.getSchema(**OpenManualReceiverControlReque**
stType.class),xmlBindingModel.**getBeanDescriptor(**
OpenManualReceiverControlReque**stType.class) );
XmlAxiomDocumentContext doc = (XmlAxiomDocumentContext)fac.**
createXmlDocument(**xmlBindingModel.getSchema(**
OpenManualReceiverControlReque**stType.class),beanDesc );
OMElement openReq = doc.getDocumentInstance();*

with

*                // get the bean descriptor
                MoXmlSchema xmlSchema =
xmlBindingModel.getSchema(request.getClass());
                MoXmlBeanDescriptor xmlDescriptor =
xmlSchema.getXmlBeanDescriptor(request.getClass());
                XmlAxiomFactory xmlAxiomFactory =
XmlAxiomFactory.getInstance();
                // write the instance to XML
                XmlAxiomDocumentContext document =
(XmlAxiomDocumentContext)xmlDescriptor.persistInstance(xmlAxiomFactory,
request);

                // do the WS call
                OMElement openReq = document.getDocumentInstance();
*

Cheers,
  Yoav
