Axis and HTTP code = 100

[JeanLouis Marechaux]

Hi all,

I need your help here to figure out a problem I'm facing with Axis.

I have an Axis client (version 1.1). It sends a request to a provider, and the provider sends back a response. (Until now, everything is ok and quite simple).
Using TCPMon, I can se the provider sends 2 http response s. First a HTTP 100 (Continue), then a HTTP 200 OK

But my axis client raises an AxisFault while processing the response.
100)Continue
at org.apache.axis.transport.http.HTTPSender.readFromSocket(HTTPSender.java(Compiled Code))

Sounds like my Axis client is not able to deal with HTTP 100 (Continue)....

Any idea to solve this problem ???

Thanks in advance

after some reserch whithin AXIS source code, it sounds like http 100 (continue) is not really supported by axis if the request had no Expect : 100-continue header.

If this is true (I'm not quite sure), then it is an axis bug, as the http W3c spec mentions a server can return a http 100 status code even if the client had not required it...

I would like to find a workround to my problem,

Does anybody know how to configure/use the Axis client to have "Expect : 100-continue" in each header request ??

Workaround 1 :
Send SOAP request in HTTP 1.0, so that the server is not allowed to return a HTTP 100 Continue status.
This is not a good idea as WS-I discourage the use of HTTP 1.0 (1.1 is prefered)

Workaround 2 :
Send the SOAP request with a Expect : 100 -Continue header. Then Axis source code work fine and is able to deal with 100-Continue response

Nevertheless, with W/A 2, you need to enable the Axis chunk mode....
