    Pete,

    Please take a look at Masanori Itoh's note below
    about Java RPC problems with SM/1.0 use of the
    'xsd:union' construct. Please copy all with your
    reply.

    Thanks,
    - Ira

    Hi Mr. McDonald,

    Thank you for your support to my problem.

    After sending e-mail to Mr. Hall, I inquired that problem
    to my colleague at work, and found the reason.

    The Apache AXIS tool, WSDL2Java excutes binding from XML
    Schema to Java in accordance with JAX-RPC (Java API for
    XML-Based RPC). But the support of the schema component
    'xsd:union' is optional in JAX-RPC.
    So I guess WSDL2Java can not treat the schema component
    'xsd:union'.

    One of the solution for that problem is not to use
    the schema component 'xsd:union'.
    In the Semantic Model '1.0' schema, the schema component
    'xsd:union' is mostly used as the union of the part of
    enumerated definitions and the part of the extension of them.
    And the parts of the extension are loosely defined
    with constraining facet (e.g. 'xsd:pattern').
    So in order to solve that problem, the part of extension
    have to be defined strictly.
    But a problem remains. It is that the schema files have to
    be modified.

    I found that problem when I checked whether some WSDL
    converting tools could treat new PSI WSDL files.
    I found another problem as a matter of truth.
    Both old and new WSDL files can be treated with gSOAP tool
    (C or C++ code generator).
    The reason is gSOAP tool has poor quality.

    Some problems of generation tools were found, so I am
    anxious about the implementation of PSI prototype
    even if new WSDL files will be released.

    [I didn't copy to the SM mailing list. If needed,
    please copy this to it.]

    Thanks,

    Hi Pete,

    Please reply to Masanori Itoh about his problems with
    'xsd:union' in the final (1.0) versions of SM schema.

    [I copied the SM mailing list to make sure that others
    are aware of this problem.]

    Cheers,
    - Ira

    Subject: [Q] A problem of WSDL2Java

    Hi Mr. Hall,

    I have a problem of PSI inplementation.

    I used WSDL2Java (Axis tool) with my new WSDLs included the
    Semantic Model '1.0' schema files, but bad codes were generated.
    I think that is why 'xsd:union' are used in the Semantic Model
    '1.0' schema files.
    (In the Semantic Model '0.93' which old WSDL files use,
    'xsd:union' are not used. Java codes can be got with
    SM 0.93 .)

    I found you had a same experience.
       http://nagoya.apache.org/jira/browse/AXIS-568

    So could you tell me your solution of that problem if you have ?

    I wonder Java codes can not be automatically generated
    with WSDL2Java if the Semantic Model '1.0' is used and
    that problem remains.

    Thank you,
