Error description

  • WebSphere Application Server v7.0.0.11 XMLStreamWriter is
    outputting the wrong value. The serializer is omitting a
    required namespace prefix as follows:
    
    <test xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance"
    nil="true"></test>
    
    This causes the document to be invalid. The expected valid
    document should look like the following:
    
    <test xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance"
    xsi:nil="true"></test>

    * USERS AFFECTED:  All IBM WebSphere Application Server V7.0   *

    * PROBLEM DESCRIPTION: XMLStreamWriter is omitting required    *
    *                      namespace prefixes.                     *
    ****************************************************************
    * RECOMMENDATION:  Install a fix pack that contains this APAR. *
    ****************************************************************
    When requested to serialize XML attributes the IBM
    XMLStreamWriter will omit required namespace prefixes if the
    application did not explicitly provide them.
    
    For example, the XMLStreamWriter would incorrectly write:
    
    <test xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance" nil
    ></test>
    
    instead of:
    
    <test xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance"
    xsi:nil="true"></test>
    
    Without the "xsi" prefix the "nil" attribute is not bound to
    the correct namespace.
    

Problem conclusion

  • When no prefix has been explicitly specified for an attribute,
    an XMLStreamWriter implementation is required to use its
    namespace context to determine a prefix to write. The IBM
    XMLStreamWriter was not performing this lookup and would
    always write the attribute without a prefix. This issue was
    fixed by adding a prefix lookup call to the namespace context
    within the XMLStreamWriter method which writes the attribute.
    
    The fix for this APAR is currently targeted for inclusion in
    fix pack 7.0.0.15.  Please refer to the Recommended Updates
