Returning array of complex types
Hi,
I'm using Axis 1.2 Beta as server, and .Net WebService Studio as
client for my tests.
Almost everything is working fine, except for a strange behavior that
happens depending of the result (response) of the web service, in
methods that return arrays of complex types.
Below, it's shown two request for the same web service that returns an
array of complex types.
Hear is the example of a successfull request (i am using tcpmon to
monitore the requests and responses):
Request:
POST /axis1.2/services/ServidorMatricula HTTP/1.1
Content-Type: text/xml; charset=utf-8

I don't know what that "39b" befor <:?xml tag and that 0 at the end of response.
Now, a request and response that produce an erro at the client:
Request:

HI Eric,
Thanks for the answer!!
I really don't know how come a hidden character be in that response.
Do you have any suggestions?
I forgot to say that I am using ?wsdl for automatic generation of wsdl file.
Is there any other tool like .Net WebService Studio so I can repeat
the tests in other client?
Thanks again!!
Fabio

Re: Returning array of complex types
Posted by Eric Rajkovic <er...@oracle.com>.
Fabio,
The "39b"-"0" and "4ac"-"0" are the chunking size, related to chunked transfer.
They are the chunk-size - last-chunk, as defined in the Hypertext Transfer Protocol -- HTTP/1.1
specification.
see http://www.faqs.org/rfcs/rfc2616.html, section 3.6.1 Chunked Transfer Coding
From the parser error on the second request/response it looks like if you
have some hiden character on the first line of the second response, before
the XML declaration (<?xml version="1.0" encoding="utf-8"?>).
The only character valid there are for the Byte Order Mark (BOM)
see http://www.w3.org/TR/REC-xml/#sec-prolog-dtd
hope this helps,
eric
