Hi Bo, Sorry for getting back so late. I missed your mail from my email pool.
I indeed used axis2 1.1 and with xbean-2.2.0.jar that is shipped with the release. This is what I did to prove that polymorphism in XML works. My schema defines three complex types - BaseAddress, USAddress, and UKAddress. The second item extends first and the third item extends second. There is an element called 'UpdateCustomerAddress' that includes, by signature, type BaseAddress unbounded. The element could be used in the WSDL messages, but I didn't want go there. Now I complied the schema using the schema compiler tool from XML beans. (It makes no difference whether you use WSDL2Java of axis2 or directly compile using scomp of XML beans). I then wrote a test class, which uses the XML beans classes generated classes, to verify the runtime object type for the address property in UpdateCustomerAddress document. Please refer to the attachment for the schema and test class. In essence, the test class creates an XML programmatically, which contains a BaseAddress, an USAddress, and UKAddress all bound to the addresses property. Then it dumps the objects into XML, re-parses it, and examines the objects using instanceof operator to ensure that the types are correctly created. The test output is also in the attachment. TIP: I am not sure if this is significant, but ensure that your schema's elementFormDefault is "qualified" I hope this helps you. Ramesh On 1/9/07, Bo Xie <[EMAIL PROTECTED]> wrote:
Hi Ramesh,
Did you by any chance use Axis2 1.1.1 instead of 1.1 for your testing?
If you indeed used 1.1 only, can you give some details on how did you test
the instanceof? BTW, I opened AXIS2-1938 for this issue before saw your last
reply.
Thanks,
-Bo

the instanceof test. I would like to see if I am not doing the right thing
using the generated object. Did you see the xsi:type in the soap message for
both directions?
