Interoperability problem wit Attachments ?

[Dorner Thomas <Th...@t-systems.com>]

Hi all, hi Dhanush,
 
Thank you Dhanush for you reply.
 
After a few days of testing to send a attachment with DIME from AXIS-Service
to gsoap-client,
we are really down. SO I hope someone can give us a hint.
 
First of all, we send from the Service:
 
Message rspmsg = AxisEngine.getCurrentMessageContext().getResponseMessage();
rspmsg.setMessageType(org.apache.axis.Message.MIME_APPLICATION_DIME);
 
DataHandler dh = new DataHandler(new FileDataSource(fileName));
AttachmentPart ap = new AttachmentPart(dh);
 
MessageContext context=MessageContext.getCurrentContext();
Message responseMessage = context.getResponseMessage();
responseMessage.getAttachmentsImpl().addAttachmentPart(ap);
 
The difference is, that gsoap only know the pratice of sending the
attachments by a Data-typ!?
If you look at a gsoap SOAP-Trace, when sending a attachment, there is a
href:cid:... as attribute in the response-Element
of the SOAP-Body, referencing the attachment.
 
This is the same prytice as sending a Datahandler in AXIS.
 
Can someone please tell me if it is possible to send a attachment from AXIS
to gsoap?????????
--> A YES or NO would be enough
 
Can someone pls tell me whats the right way of making this working?????????
Short hints would be wonderfull - please!!! :)
 
It is very interesting for us, if someone before make this working????
 
Thanks for help
 
Tomi

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.

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
