Hi all!
I'm using axis for sending and receiving SOAP message based requests
with attachments (multipart mixed). When sending a message through the
TCPMonitor I can see that the length is set to some value e.g.
"Content-Length: 2821", on the receiving side (the server is also
implemented using axis) the following is reported (the error occurs when
trying to read the attachments):
<soapenv:Fault>
<faultcode>soapenv:Server.userException</faultcode>
<faultstring>javax.xml.soap.SOAPException: Simulator failed to
process message: ; nested exception is:
java.io.IOException: End of stream encountered before final
boundary marker.</faultstring>
<detail/>
</soapenv:Fault>
Now, if I simply resend the message from the TCPMonitor (without any
modifications) I can see that the length is recalculated, e.g. to:
"Content-Length: 3323" and this is the only change to the message being
sent. The server accepts this and is able to read the attachments.
I suspect that there may be something wrong in the code that adds my
attachments, the code that adds the attachments looks like:
org.apache.axis.attachments.AttachmentPart ap =
new org.apache.axis.attachments.AttachmentPart();
MimeMultipart mimeMultipart = new MimeMultipart("mixed"); MimeBodyPart
mimeOuterBodyPart = new MimeBodyPart();
mimeOuterBodyPart.setContent(mimeMultipart);
ap.setDataHandler(mimeOuterBodyPart.getDataHandler());
//Add MimeBodyParts to the mixed MimeMultipart
for (int i = 0; i < content.length; i++) {
MimeBodyPart mimeBodyPart = encodeContentInMimeBodyPart(content[i]);
mimeMultipart.addBodyPart(mimeBodyPart);
}
soapCall.addAttachmentPart(ap);
Vector returnElements = (Vector) soapCall.invoke(input);
Where encodeContentInMimeBodyPart:
private static MimeBodyPart encodeContentInMimeBodyPart(MM7SOAPContent
content)throws java.io.IOException, javax.mail.MessagingException {
MimeBodyPart mimeBodyPart = null;
mimeBodyPart = new MimeBodyPart();
//Use the ByteArrayDataSource helper class
DataSource dataSource = new
ByteArrayDataSource((byte[])content.getContentData(),
(String)content.getContentType());
DataHandler dh = new javax.activation.DataHandler(dataSource);
mimeBodyPart.setDataHandler(dh);
//Set correct content ID
mimeBodyPart.setHeader("Content-ID", content.getContentID());
mimeBodyPart.setHeader("Content-Location", content.getContentID());
return mimeBodyPart;
}
The message I'm trying to send has the following structure:
SOAP HEADER
SOAP Body
Attachments wrapped in a multipart/mixed part (where attachments shall
be encoded as base64 for "binary files" such as jpegs and gifs)
When the client is implemented with Apache SOAP and the server is
implemented with Axis all is OK... When the client is implemented with
Axis and the server is implemented with Apache SOAP all is OK... When
the both are implemented with axis it is NOT ok... I guess that Apache
soap calculates the correct length and that it does not use the
Content-Length indicator in the header for incoming messages.
When sent the message looks something like:
POST /myService HTTP/1.0
Content-Type: multipart/related; type="text/xml";

Any suggestions? What needs to be done in order to get a correct length
calculation?
