R: HashMap of HashMaps

[Claudia Mavilio <cl...@seceti.it>]

Hello Everybody,

I have the same Lyndon's problem, because I deploy a java webservice
that incapsulate response data into a Hashmap (whose name is "dati",
please see below) using a wsdd file.
The kind of response data into the Hashmap is of type "Costruttore" and
doesn't appear in wsdl file, so the generation of stub and
deserialization classes fails.
Follow a snippet of mi wsdl file and a copy of the wsdd file.
Thanks in advance for any help!!!

Claudia

Subject:    HashMap of HashMaps

Hello,

I have a custom object I am trying to pass across the wire using AXIS
wrapped style \
document-literal service.

The complex object contains a HashMap of HashMaps (that is, the values
of the \
HashMap, are HashMaps themselves).  For reference, I have called this
complex object \
"ExternalDataWrapper".

I have used the Java2WSDL tool to generate the WSDL for this class by
supplying the \
Interface.  Of course, the Interface does not specify that the HashMap's
values will \
contain HashMaps, so it seems that the WSDL generated declares that the
"type" of the \
value components of my HashMap will contain an "xsd:string".  A portion
of the WSDL \
follows:

<schema targetNamespace="http://xml.apache.org/xml-soap"  \
xmlns="http://www.w3.org/2001/XMLSchema"> <complexType name="mapItem">
  <sequence>
    <element name="key" nillable="true" type="xsd:string" /> 
    <element name="value" nillable="true" type="xsd:string" /> 
  </sequence>
</complexType>
<complexType name="Map">
    <sequence>
      <element maxOccurs="unbounded" minOccurs="0" name="item" \
type="apachesoap:mapItem" />   </sequence>
  </complexType>
</schema>
<schema targetNamespace="http://beans.xdb.geocortex.net" \
xmlns="http://www.w3.org/2001/XMLSchema">  <complexType
name="ExternalDataWrapper">
    <sequence>
      <element name="data" nillable="true" type="apachesoap:Map" /> 
    </sequence>
  </complexType>
.
.
.

I then used the WSDL2Java tool to generate the client stubs, server
skeletons and \
bindings, and the .wsdd files.  When I make a request to my webservice
(which should \
return my complex object), I construct the HashMap of HashMaps in the
Web Service \
implementation class.  The response is serialized correctly as follows:
\
<soapenv:Envelope .....>  <soapenv:Body>
    <getDataResponse xmlns="my.namespace">
      <getDataReturn xmlns="">
        <data>
          <item
xmlns:soapenc="http://schemas.xmlsoap.org/soap/encoding/" \
xmlns:nsl="http://xml.apache.org/xml-soap">  <key>123</key>
            <value>
              <item>
                 <key>OWNER</key>
                 <value>Miller</value>
              </item>
              <item>
                 <key>AGE</key>
                 <value>42</value>
              </item>
              .
              .
            </value>
          </item>
          <item>
            <key>456</key>
            <value>
               <item>
                .
                .
                .
         </data>
       </getDataReturn>
     </getDataResponse>
  </soapenv:Body>
</soapenv:Envelope>    


The problem is, that the client side does not seem to be able to
deserialize my \
ojbect correctly.  Perhaps it is expecting a string as the values of the
HashMap as \
opposed to HashMaps.

It is giving me this error:
org.xml.sax.SAXException: SimpleDeserializer encountered a child
element, which is \
NOT expected, in something it was trying to deserialize.

My question is: Why can this object be seeminly serialized correctly if
it can not be \
deserialized?   Is deserializing multidimentional HashMaps a limitation
of the Axis \
deserializers?

Any suggestions would be appreciated.

Thanks for your time.
