How to send binaries as base64?

[Marc Schmidt <ma...@1und1.com>]

Hi All.

To keep it short.

I want to send an array of binaries from a java app to a soap server
using
axis.

Here the part of the wsdl:
  
<complexType name="ArrayOf_xsd_base64Binary">
	<complexContent>
     		<restriction base="soapenc:Array">
      		<attribute ref="soapenc:arrayType"
wsdl:arrayType="xsd:base64Binary[]"/>
     		</restriction>
    	</complexContent>
</complexType>
<complexType name="PictureContainer">
	<sequence>
     		<element name="allPages" nillable="true"
type="impl:ArrayOf_xsd_base64Binary"/>
    	</sequence>
</complexType>

Through the axis.wsdl compiler it mapps perfectly to byte[][].

But the xml-output eventually evolving looks like this:

  <multiRef id="id1" soapenc:root="0"
soapenv:encodingStyle="http://schemas.xmlsoap.org/soap/encoding/"
xsi:type="ns3:STGPictureContainerVO" xmlns:ns3="http://bla" 
xmlns:soapenc="http://schemas.xmlsoap.org/soap/encoding/">
   <allPages xsi:type="soapenc:Array" soapenc:arrayType="xsd:byte[][1]">
    <item soapenc:arrayType="xsd:byte[15072]">
     <item>0</item>
     <item>0</item>
     <item>-125</item>
     <item>48</item>
	...

I do not expect each and every single byte to be tagged. I would rather
like to see
something like a stream:
          <allPages xsi:type="soapenc:Array"
soapenc:arrayType="xsd:base64Binary[1]">          
            <item xsi:type="xsd:base64Binary">
	
lGODdhwAb7CJAAAP///wAAACwAAAAAwAb7CAAC/4SPqcvtD6OctNqLs968
		</item>
          </allPages>

How do I get there? I cannot attach the binaries using MIME. They
unfortunately need
to be encoded base64 and contained in the soap envelope.

Help of any type is appreciated.

Cheers

Marc,

I had a similar problem, but some details are different. In my case, I had
to send a single binary, not an array of them. Also, I was retrieving the
binary from the server, not sending them to the server.

When I exposed the operation within a doc/lit service, I saw exactly what
you see - each byte gets its own tag, bloating the returned results.

When I exposed the operation within an rpc/enc service, I saw exactly what
you want - data gets base64-encoded within the SOAP response.

On looking through the WSDLs for both cases, I saw that in the doc/lit case,
the return value was essentially "sequence of bytes", but for the rpc/enc
case, it was "base64binary". Perhaps that accounts for the differences.

Hope that helps.
