Subject Re: Axis 1.4 CommonsHTTPSender question
Date Thu, 20 Sep 2007 16:22:03 GMT
Thanks for the feedback Jeff! That helps. I do have a follow up question for you or anyone
else in the group. Is the way I am setting the client to programattically utilize CommonsHTTPSender
for the transport correct? I believe it is, or at least it has an effect, since without it,
the connection works fine. I have tried setting the chunked property to false with the following
code and it does not appear to be working:

        Hashtable httpHeaders = new Hashtable();        
        httpHeaders.put(HTTPConstants.HEADER_TRANSFER_ENCODING_CHUNKED, false);
        _call.setProperty(HTTPConstants.REQUEST_HEADERS, httpHeaders);

Also, if it is using CommonsHTTPSender, I should not have to set a property to get it to use
HTTP 1.1, correct? However, in the tcpmon output, for some reason the second connection (which
I still don't know where the second and third attempted connections are coming from) clearly
uses 1.0, while the other two use 1.1. Is this an automatic retry under 1.0 if the 1.1 connection
fails for some reason? I have tried adding in the following line with no discernible effect.

httpHeaders.put(MessageContext.HTTP_TRANSPORT_VERSION, HTTPConstants.HEADER_PROTOCOL_11);

I am including the output below from tcpmon for what is a SINGLE call to invoke on my _call
object. You can see it results in 3 connections, and for some reason, it doesn't seem to be
taking the headers. At the very bottom, I include the output from the successful Request (not
using CommonsHTTPSender) for reference.

Thanks again in advance!

Mario-

The contents of each Request and Response are the same except for the fact that in the POST
HTTP 1.0 version, the chunked string information you talked about is not present in the response.
So I am only posting each one once.

Request:

Mario,
I can answer the "4c5" "0" before and after question, but not the three
firings.
Go here to see why the numbers come out: http://wso2.org/library/952
We get transfer encoding = chunked turned on by default in HTTP 1.1, and
I think you would prefer it turned off.

Subject: Axis 1.4 CommonsHTTPSender question

Hello all!

I have a client where before setting the client to use
CommonsHTTPSender, it worked fine. The client would post using HTTP 1.0,
and it would do so once only and everything was fine.

Now, since it is a programmatically defined client, I activate the
CommonsHTTPSender by adding the following lines to the client:

CommonsHTTPSender reqHandler = new CommonsHTTPSender();
CommonsHTTPSender respHandler = new CommonsHTTPSender();
_call.setClientHandlers(reqHandler, respHandler);

The following line is added to the server-config.wsdd:

 <transport name="http"
pivot="java:org.apache.axis.transport.http.CommonsHTTPSender" />


The behavior I am seeing in tcpmon when NOT using CommonsHTTPSender is:

POST /axis/services/USERSERVICE HTTP/1.0
Content-Type: text/xml; charset=utf-8
Accept: application/soap+xml, application/dime, multipart/related,
text/*
User-Agent: Axis/1.4
Host: 127.0.0.1:8888
Cache-Control: no-cache
Pragma: no-cache
SOAPAction: ""
Content-Length: 1088

<![CDATA[SOMEUSERDATA]]>

The behavior I am seeing in tcpmon when I use CommonsHTTPSender is
listed below, however it is also notable that it fires three times
instead of once, all on its own. The first and third time are HTTP 1.1,
and the middle one is HTTP 1.0. I'm not sure why this behavior exists as
well. 

Additionally, there are these strings before and after the soap content,
the string before is 4c5 and the string after is 0. I don't know where
these come from either, and if these are the reasons for the 3 seperate
calls.

Anyway, the tcpmon is:

POST /axis/services/USERSERVICE HTTP/1.1
Content-Type: text/xml; charset=utf-8
SOAPAction: ""
User-Agent: Axis/1.4
Host: 127.0.0.1:8888
Transfer-Encoding: chunked

4c5

Any help or guidance would be greatly appreciated!!

Thanks in advance,
