Hi Thomas,
You can use any of the form u want. But I
dont know how your gsoap client will handle it. It is better if you use the
first way (Using Attachment Parts), where the attachment doesnt have a reference
in the SOAP Body. Here the one good thing u never need to modify ur
WSDL.
When u use the Datahandler way( In line
form), the experts say that there can be a problem when u send huge files as
attachemnts. Also u need to have the return parameters described in the WSDL. Of
course u can set the filename in the Datahandler itself.
But I dont think setting the filename is
a problem in the AttachmentParts way . You can set this in the SOAP Header of
the SOAPMessage using some handlers.
Please refer the following mail archives

Subject: SOAP with Attachments ?
Hello all,
I like to send an attachment
from my Service to the client.
So there are several possible ways to
go:
The first ist to place a attachment in the
responseMessage:
String fileName =
"C:\\WebService\\webapps\\PDMWebConnector\\arrow.gif";
//explicitly set
format to DIME, default is MIME
Message rspmsg =
AxisEngine.getCurrentMessageContext().getResponseMessage();
rspmsg.getAttachmentsImpl().setSendType(org.apache.axis.attachments.Attachme
nts.SEND_TYPE_DIME);
DataHandler
dh = new DataHandler(new FileDataSource(fileName));
if (dh == null )
System.err.println("dhSource is null");
AttachmentPart ap = new
AttachmentPart(dh);
rspmsg.addAttachmentPart(ap);
The other
way is to send back the datahandler itself
public Datahandler
download(java.lang.String request) throws
java.rmi.RemoteException
{
...
The difference is in the SOAP-Message. If I send a
Datahandler back,
I got a SOAP-Message with a href in my SOAP-Body,
referencing the
Attachment behind my SOAP-Message.
In the other
way, when I send back the added AttchmentPart, I got no
reference in
my
SOAP-Body.
Whats the right way to go???
Is there a solution
to place Filename or addional information when I send
a
Datahandler?
Please help me!
I wanna send Data from a
Java-Service to a gsoap Client!!!
Thanks
Tomi
