Hello all,
I have written a SOAP client using Axis2 which receives a binary file in the
response. The binary file is attached using MOTM XOP. When I use an http
sniffer to look at the response everything looks good...the response
contains an XOP:Include reference to the attached content. The attached
content in this case is sent as binary but it's just an XML file which I can
visually inspect.
However, when I print out the respsonse with the following code:
OMElement result = servClient.sendReceive(method);
System.out.println(result);
I get this body:
<soap:Body></soap:Envelope>
<PassExcelBinaryResponse
xmlns="http://XXXXXXXX/soap/WebServices.asp";><PassExcelBinaryResult>PD94bWwgdmVyc2lvbj0iMS4wIiBzdGFuZGFsb25lPSJ5ZXMiPz4NCjxOZXdEYXRhU2V0Pg0KICA8eHM6c2NoZW1hIGlkPSJOZXdEYXRhU2V0IiB4bWxucz0iIiB4bWxuczp4cz0iaHR0cDovL3d3d........LOTS
AND LOTS MORE
The size of the attached binary file is 900K. The size of the content in
PassExcelBinaryResult is suspiciously around 30% larger...it looks like
Axis2 (Axiom?) has encoded the attached file.
For reference here is my code to write the attached binary:
OMText binaryNode = (OMText)xmlElement.getFirstOMChild();
DataHandler dh = (DataHandler)binaryNode.getDataHandler();
FileOutputStream out = new FileOutputStream("../../test/data/temp.xml");
dh.writeTo(out);
out.close();
So my question: Is Axis2 encoding the binary attachment merely for display
purposes? Or will it try to encode the binary attachment and then have to
decode it when I write the file.
As mentioned using the above code is working however it is very slow..it is
about 4x slower to read the attachment than an equivalent client written for
.NET. This is what led me to start wondering why it was so slow and seeing
that the content seemed to be encoded after I receive the response.
Thanks,
Derek
