[Axis2] redirection with Axis2 ?
Hi,
I have a web service deployed in Axis2.1.2/Tomcat5.5 at
'http://localhost:8080/axis2/services/myService'
I have set the endpoint to
'http://localhost:8080/axis2/services/myService' in my client and
everything's working fine.
Now, I need to implement a redirection mechanism. For this, I first
downloaded and installed a free URL rewrite module
(http://tuckey.org/urlrewrite/), similar to mod_rewrite of Apache.
In this module, I configured a redirection rule with something like this:
from=http://localhost:8080/axis2/services/myNewService
to=http://localhost:8080/axis2/services/myService
I also changed the endpoint used by my client to
'http://localhost:8080/axis2/services/myNewService'.
Note that the web service is still deployed at
'http://localhost:8080/axis2/services/myService'.
I started the updated client and I received the following error when the
client calls an operation of the web service:

In the traces of the URL rewrite module, the change of URL seems to be
performed correctly.
I repeated the same test with TCPmon. The incoming request looks like this:
----------------------------------------------------------------------
POST /axis2/services/myNewService HTTP/1.1
Content-Type: text/xml; charset=UTF-8
SOAPAction: "myOperation"
User-Agent: Axis2
Host: localhost:9090
Transfer-Encoding: chunked
2ae
<?xml version='1.0' encoding='UTF-8'?>
<soapenv:Envelope xmlns:wsa="http://www.w3.org/2005/08/addressing"
xmlns:soapenv="http://schemas.xmlsoap.org/soap/envelope/">
<soapenv:Header>
<wsa:To>http://localhost:9090/axis2/services/myNewService</wsa:To>
<wsa:MessageID>urn:uuid:6774F9EFDB67A1F15A1181830925356</wsa:MessageID>
<wsa:Action>myOperation</wsa:Action>
</soapenv:Header>
<soapenv:Body>
...
</soapenv:Body>
</soapenv:Envelope>0
----------------------------------------------------------------------
... and the response looks like this
----------------------------------------------------------------------
HTTP/1.1 302 Moved Temporarily
Server: Apache-Coyote/1.1
Location: http://localhost:9090/axis2/services/myService
Content-Length: 0
Date: Thu, 14 Jun 2007 14:22:05 GMT
----------------------------------------------------------------------
I searched the mailing list archives for this kind of error but I didn't
find any solution for it.
Can someone shed some light on how redirection works in Axis2 ? Did I
foget to configure something in Axis2 ? Is my scenario doable with
Axis2.1.2 in the first place ?
Thanks in advance.

Please log a JIRA. It seems our client HTTP code is not following redirects.
If the service is still on the same machine and you want to have it
rerouted (say to a new version) then there might be other ways of
doing that - for example you could use Synapse or you could write a
really simple module for Axis2 that adjusts the To: address before you
start dispatching.
