So,
you have a bunch of questions, and I have only a suggestion, or two.
I'm not convinced the way you programmatically setup the sender is
correct. Perhaps your way is right (or almost right) but I would have
approached it like this:
...
EngineConfiguration defaultConfig = (new
DefaultEngineConfigurationFactory()).getClientEngineConfig();
SimpleProvider config = new SimpleProvider(defaultConfig);
SimpleChain c = new SimpleChain(new CommonsHTTPSender());
config.deployTransport("http", c);
...
Service service = new Service(config);
Call call = (Call)service.createCall();
...
then set the bewielding array of parameters on the Call object. (This is
why most people don't do dynamic clients, these parameters are too hard
to get right). Now, I did not test the above code, so I have no real
idea if it is correct.
Yes, CommonHTTPSender seems to use 1.1 by default. Which makes me think
the two handlers you setup are in fact using CommonsHTTPSender (because
they sent their requests using 1.1) and the middle request was sent by
the default HTTPSender, which I suspect still uses HTTP 1.0.
-jeff
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" />

Ugh...once again, had some of the code eaten. Putting it back in
under the first Request: block.

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,
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!!
