Hi
I am using Axis 1.1 to call a wrapped service.
I have a simple Java class
public class Test
{
�public TestResponse callMethod( String method,
String[] params )
�{
��return( null );
�}
}

The wsdl for this Java class was produced using
org.apache.axis.wsdl.Java2WSDL, the options --style
WRAPPED --use LITERAL specified.
The client stub and server impl were produced using
org.apache.axis.wsdl.WSDL2Java.
When the service is called the following SOAP request
and AXIS fault response are produced :-
�
<?xml version="1.0" encoding="UTF-8"?>
<soapenv:Envelope
xmlns:soapenv="http://schemas.xmlsoap.org/soap/envelope/"
xmlns:xsd="http://www.w3.org/2001/XMLSchema"
xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance">
�<soapenv:Body>
� <callMethod xmlns="http://wrapped.test.com">
�� <method xmlns="">test</method>
�� <params xsi:type="Array"
soapenc:arrayType="xsd:string[0]"
xmlns:soapenc="http://schemas.xmlsoap.org/soap/encoding/"
xmlns=""/>
� </callMethod>
�</soapenv:Body>
</soapenv:Envelope>
<?xml version="1.0" encoding="UTF-8"?>
<soapenv:Envelope
xmlns:soapenv="http://schemas.xmlsoap.org/soap/envelope/"
xmlns:xsd="http://www.w3.org/2001/XMLSchema"
xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance">
�<soapenv:Body>
� <soapenv:Fault>
�� <faultcode>soapenv:Server.userException</faultcode>
�� <faultstring>org.xml.sax.SAXException: No
deserializer defined for array type
{http://www.w3.org/2001/XMLSchema}string</faultstring>
�� <detail/>
� </soapenv:Fault>
�</soapenv:Body>
</soapenv:Envelope>

Firstly, I am a little confused why when --use LITERAL
is specified to Java2WSDL that the string array is
still SOAP encoded ?. I have seem some debate on this
issue recently.
�
Secondly, the problem I am seeing appears to be caused
by the attribute xsi:type="Array" on the <params>
element. The value "Array" is not indicated to be in
the http://schemas.xmlsoap.org/soap/encoding/"
namespace using the defined "soapenc" prefix.

On further investigation this may be caused by a what
appears to be a bug in the class
org.apache.axis.utils.NStack. The stack believes that
"http://schemas.xmlsoap.org/soap/encoding/" namespace
is the default namespace and hence does not require a
prefix. This only occurs at the point when this
attribute is serialized.
�
I would appreciate your thoughts/advice, Is this a bug
? am I doing something wrong ?
�
Thanks
Steve
