Subject: SOAP4r sequences and authentication

Hi,

I've been asked to generate a SOAP client for a J2EE project. I've been
given a wsdl file and running wsdl2ruby on it generates a working client.

The problem I'm having is in retrieving multiple items from the server.
The wsdl file contains the following:

   <complexType name="Channel">
    <xsd:sequence>
       <xsd:element name="code" type="xsd:string" nillable="false"/>
       <xsd:element name="name" type="xsd:string" nillable="false"/>
       <xsd:element name="category" type="xsd:string" nillable="false"/>
    </xsd:sequence>
   </complexType>
   <complexType name="ChannelList">
     <sequence>
        <element maxOccurs="unbounded" minOccurs="0" name="Channel"
type="epg:Channel"/>
      </sequence>
   </complexType>


and wsdl2ruby generates these classes:

class Channel
  @@schema_type = "Channel"
  @@schema_ns = "http://test.com.au"

  def code
    @code
  end

  def code=(value)
    @code = value
  end

  def name
    @name
  end

  def name=(value)
    @name = value
  end

  def category
    @category
  end

  def category=(value)
    @category = value
  end

  def initialize(code = nil,
      name = nil,
      category = nil)
    @code = code
    @name = name
    @category = category
  end
end


class ChannelList
  @@schema_type = "ChannelList"
  @@schema_ns = "http://test.com.au"

  def Channel
    @channel
  end

  def Channel=(value)
    @channel = value
  end

  def initialize(channel = nil)
    @channel = channel
  end
end

When I run the generated client.rb file and call listAllChannels, which is
supposed to return a ChannelList containg a number of channels, only one
channel is returned. I assume that this is due to the ChannelList class
only holding one Channel.

Is there a way of generating a client that returns an array of channels
using wsdl2ruby.rb from the wsdl file shown above?

I've had a brief look at some of the SOAP spec and it looks like using
SOAP-ENC:Array for the ChannelList may have been a better description of
the data but I'm not in a position to change that.

On a related issue how would I go about passing authentication data
username and password with a SOAP request?

TIA,

Martin
