hi robert,
i've never used jibx2wsdl before, but what this tool does in terms of
jibx will be "normal" marshalling and unmarshalling, i guess.
when i look at your binding a see that the mapping for
ExchangePermissionBO is abstract, which means it can NEVER be the root
element in your xml. furthermore, as it is abstract, it doesn't hold
any information what the resulting tag will be named.
from my point of view, the <mapping> entry must look like this:
<mapping name="ENTER_THE_TAG_NAME_HERE" abstract="true" type-
name="tns:exchangePermissionBO"
class="com.wazollc.alphatheory.hibernate.bo.ExchangePermissionBO">
....
then the code to create XML from this object would be:
IBindingFactory bfact = BindingDirectory.getFactory("binding",
ExchangePermissionBO.class);
IMarshallingContext mctx = bfact.createMarshallingContext();
mctx.marshalDocument(bo, "UTF-8", null, new
FileOutputStream("filename.xml"));
br,
günther
