encoding for Array of Datahandler objects

[robert rowntree <ro...@mindspring.com>]

one of the IBM WSTK samples ( attachments ) using RPC has an existing SOAP
"parts" list of :

 1.string
 2.string []
 3.dataHandler for a java class
 4.dataHandler for a jpg file
 5.dataHandler for an Html file

The practical effect of the sample is to transfer files in above parts 3, 4,
and 5 from the client to the server over HTTP/SOAP.

I want to change this so that an Array of DataHandlers for MIME type text is
passed over the wire.

 So my new Parts would be:

1.string
2.string []
3.dataHandler []  for MIME type "text" this is where all my attached files
goes.

  and my new WSDL for the interface would look something like

 <message name="RPCRequest">
  <part name="listTitle" type="xsd:string" />
  <part name="fileList" type="types:ArrayOfString" />
  <part name="fileArray" type="types:ArrayOfDataHandler" />  // would have
many files here
 </message>

- <complexType name="ArrayOfDataHandler">
- <complexContent>
- <restriction base="soapenc:Array">
  <attribute ref="soapenc:arrayType" wsdl:arrayType="xsd:DataHandler[]" />
  </restriction>
  </complexContent>
  </complexType>

 * * * endof myPropsed WSDL

Can you help me alter the following from the original sample so that an
Array of DataHandlers is encoded correctly as the 3rd part of the RPC:

A.  WSDL for the interface  ( see below from original )
B.  WSDD for the serializer  ( for files to be serialized using a
DataHandler )
C.  Java file for the Server-side service


*** Original Code from the IBM sample ***

A. * * WSDL for the interface * *

- <xsd:schema xmlns="http://www.w3.org/2001/XMLSchema"
targetNamespace="http://www.attachment.com/types">
- <complexType name="ArrayOfString">
- <complexContent>
- <restriction base="soapenc:Array">
  <attribute ref="soapenc:arrayType" wsdl:arrayType="xsd:string[]" />
  </restriction>
  </complexContent>
  </complexType>
- <complexType name="ArrayOfBinary">
- <complexContent>
- <restriction base="soapenc:Array">
  <attribute ref="soapenc:arrayType" wsdl:arrayType="xsd:byte[]" />
  </restriction>
  </complexContent>
  </complexType>

- <complexType name="contentType">
- <simpleContent>
- <extension base="xsd:string">
  <attribute name="part" type="xsd:string" />
  <attribute name="type" type="xsd:string" />
  </extension>
  </simpleContent>
  </complexType>
- <element name="attachments">
- <complexType>
- <sequence>
  <element name="content" type="types:contentType" />
  </sequence>
  </complexType>
  </element>
</xsd:schema>

 <message name="RPCRequest">
  <part name="listTitle" type="xsd:string" />
  <part name="fileList" type="types:ArrayOfString" />
  <part name="classFile" type="types:ArrayOfBinary" />   this should change,
but how
  <part name="imageFile" type="types:ArrayOfBinary" />   this should change
  <part name="htmlFile" type="xsd:string" />
 </message>

B. ***  WSDD for the serializer

<typeMapping
deserializer="org.apache.axis.encoding.ser.JAFDataHandlerDeserializerFactory
"
  encodingStyle="http://schemas.xmlsoap.org/soap/encoding/"
  languageSpecificType="java:javax.activation.DataHandler"
qname="ns1:DataHandler"

serializer="org.apache.axis.encoding.ser.JAFDataHandlerSerializerFactory"/>

C. *** Java file for the Server-side service

public class AttachmentService
{

 public String THETargetMethod( String listTitle, String[] fileList,
    DataHandler classFile, DataHandler imageFile, DataHandler htmlFile)

    DataHandler[] dhs= {classFile, imageFile, htmlFile};
    String ret=listAttachments( listTitle,  fileList, dhs  );
...


    for(int i=0; i< parts.length; ++i)
    {
        DataHandler datahandler= null;
        Part part= null;
        if( parts[i] instanceof Part){
          part= (Part) parts[i];
          datahandler= AttachmentUtils.getActiviationDataHandler(part);

...

 String listAttachments( String listTitle,
	String[] fileList,
     Object[] parts
    )

...

    for(int i=0; i< parts.length; ++i)
    {
        DataHandler datahandler= null;
        Part part= null;
        if( parts[i] instanceof Part){
          part= (Part) parts[i];
          datahandler= AttachmentUtils.getActiviationDataHandler(part);
        }
