Sure, the here's a Java code snippet. Unfortunately, the .NET side is a black
box to me, so I don't have any code to share. This will take the code generated
by WSDL2Java and pull out the attachments from the "content" field which is
typed as an xsd:anyType:
public static byte[] convertToBytes(NodeDocument doc)
{
Object content = null;
byte dataOUT[] = null;
content = doc.getContent();
if(content instanceof byte[])
dataOUT = (byte[])content;
else
if(content instanceof DataHandler)
{
DataHandler dhData = (DataHandler)content;
dataOUT = getBytesFromStream(dhData);
} else
if(content instanceof AttachmentPart)
{
AttachmentPart attch = (AttachmentPart)content;
dataOUT = getBytesFromStream(attch.getActivationDataHandler());
} else
{
throw new IllegalArgumentException("Could not convert to bytes
from: " + content + " Argument type is unknown!");
}
return dataOUT;
}
private static byte[] getBytesFromStream(DataHandler data)
{
InputStream in = null;
byte out[] = null;
try
{
in = data.getInputStream();
if(in != null)
{
out = new byte[in.available()];
in.read(out);
} else
{
out = new byte[0];
}
}
catch(IOException ex)
{
System.err.println("Could not get Bytes.");
ex.printStackTrace();
}
return out;
}

Does it mean that the following method should work fine if I change DataHandler
to Object? Does it work w/o any changes in the method implementation?
public String createOrUpdateContentObjectWithAttachments(String sessionID,
String containerID, String xmlString, String customerID, String contentID,
DataHandler source, String sourceFileName,
DataHandler thumb, String thumbFileName);
input argument DataHandler is sent stream. How would the client and server know
that it has to send the stream for that specific argument. You are just sending
xsd:AnyType.
Andy, do you mind sending your code. Or atleast the snippet of the method that
takes attachment as input argument?. I would appreciate if could also send your
.NET snippet.

Right, it's passed in either directly or by reference as xsd:anyType and then
the receiver has to type the anyType to determine whether its base64encoded,
SwA, or DIME. -- Andy

Nothing in that wsdl fragment indicates that there will be any MIME or
DIME based attachments.
