Attachments

[Matthias Brunner <mb...@blumenstrasse.vol.at>]

Hello,

this is a repost since I did not get any replies from the user list.
I looked at the attachments sample but realised that I cannot pass a 
DataHandler object between the functions because the client will 
eventually be written using MSSOAP and not axis. Then I read part of 
the SAAJ specification.
Now I am quite confused. If I understood the spec correctly, the 
following code should be possible (and sufficient) for using 
attachments. Should this work and the Exception I get is due to axis 
not correctly implementing the spec? Or is it me who is wrong?

Server:
public class MyService {
public String call()
{
	SOAPMessage msg =
		MessageContext.getCurrentContext().getResponseMessage();	
	msg.addAttachmentPart(msg.createAttachmentPart("string1",
						 "text/plain"));

	return "string2";
}
}

Client:

...
call.setOperationName("call");
Object[] args = new Object[] {};
String ret = (String) call.invoke(args);
...


I see in tcpmon that there IS attachment content (which seems to be 
correct) but nevertheless there is a SAXParseException thrown on 
client side. Did I make any mistakes?

Software: Axis 1.0, Tomcat 4.1.12, JDK 1.4.1, Linux

Re: Created attachments unreadable

When doing the same with DIME as the return type I get the following 
message. (Again, serializiation works, only deserialization does 
not.)
