Re: HTML Status Code 302 And Exception When Contacting IIS Service
Hi Rick-
1st make sure you are enabling HTTP 1.1 protocol and chunkedEncoding
transfer-encoding as in this example from /conf/axis2.xml
<transportSender name="http"
class="org.apache.axis2.transport.http.CommonsHTTPTransportSender">
<parameter name="PROTOCOL">HTTP/1.1</parameter>
<parameter name="Transfer-Encoding">chunked</parameter>
<!-- If following is set to 'true', optional action part of the
Content-Type will not be added to the SOAP 1.2 messages -->
<!-- <parameter name="OmitSOAP12Action">true</parameter> -->
</transportSender>

Re: HTML Status Code 302 And Exception When Contacting IIS Service
Posted by mg...@hotmail.com.
Hi Rick-
take a look at explanation of HTTP 302 return code
http://www.w3.org/Protocols/rfc2616/rfc2616-sec10.html
The method used for transmitting the request makes the difference on whether
or not you are able to redirect to location field returned with the 302..in
other words POST cannot redirect..but GET and HEAD can redirect
Also since the redirect might be altered the client must continue to use the
original URI
as a quick test I would try to determine if you have any proxies, firewalls
or NAT servers changing the url, port or webapp between you and the
webservice
The admin of the webservice is obligated to provide you with the following
information
a)The web service site (address or CNAME) must exist and be reachable
b)The web service admin must provide a wsdl from the published service
c)Use the provided wsdl to establish your own client stubs to transmit
request to the waiting Service
If any of these items fails recode it in a working webservice environment
such as Axis and use that...
Anyone else?

Re: HTML Status Code 302 And Exception When Contacting IIS Service
Posted by Rick Strong <rs...@panix.com>.
I don't think there are any spaces in any of the names involved. (I put
a few underscores in the changed names below.) I can see exactly where
the exception is ocurring - it's in HTTPSender.readFromSocket(), where
it detects the 302 status, closes the socket, clears the status code,
and sends it off to invoke() where it tries to construct a new URL based
on the 'location' field. Unfortunately, I seem to be getting an
incomplete spec for a URL in 'location' - it's missing the protocol and
the hostname.
(Emphasis here on the fact that I can talk with my own services just fine.)
Would there be anything else I have to do if they are trying to send me
back a url rather than plain text or xml?

Re: HTML Status Code 302 And Exception When Contacting IIS Service
Posted by Martin Gainty <mg...@hotmail.com>.
Hi Rick-
most DNS servers wont do lookups on DNS CNAMEs for ServerName With Spaces
but rather CNAMEs without spaces such as
private static String URL =
"http://127.0.0.1:8080/axis2/services/AddressBookService";
Call.java throws MalformedURLException when the EPR (URL) is malformed

Re: HTML Status Code 302 And Exception When Contacting IIS Service
Posted by Rick Strong <rs...@panix.com>.
Hi Martin,
Thanks. I added the following to my own code while configuring the call:
call.setProperty(MessageContext.HTTP_TRANSPORT_VERSION,
HTTPConstants.HEADER_PROTOCOL_V11);
Hashtable chunkedTable = new Hashtable();
chunkedTable.put(HTTPConstants.HEADER_TRANSFER_ENCODING,
HTTPConstants.HEADER_TRANSFER_ENCODING_CHUNKED);
call.setProperty(HTTPConstants.REQUEST_HEADERS, chunkedTable);
Now I get similar results, but with one additional go-round. In
HTTPSender.readFromSocket, the first iteration gives me a 100
(continue), then when I do so, I get the 302 again, then the
MalformedURLException.
I should probably mention that this is Axis 1.4, Java 1.5 (OS X)
