Hi all,
I am trying to use the same example.
I am encoutering the same problem. I have also caught the http request
inside tcpmon.
You can find it hereafter :
POST /axis2/services/RMSampleService HTTP/1.1
User-Agent: Axis2
SOAPAction: http://schemas.xmlsoap.org/ws/2005/02/rm/CreateSequence
Host: localhost:13000
Transfer-Encoding: chunked
Content-Type: text/xml; charset=UTF-8
320
<?xml version='1.0' encoding='UTF-8'?>
<soapenv:Envelope

<soapenv:Header>

<wsa:ReplyTo>
<wsa:Address>http://129.183.18.65:6060/axis2/services/__ANONYMOUS_SERVICE__/__OPERATION_OUT_IN__</wsa:Address>
</wsa:ReplyTo>

<wsrm:CreateSequence xmlns:wsrm="http://schemas.xmlsoap.org/ws/2005/02/rm";>
<wsrm:AcksTo>

</wsrm:AcksTo>
</wsrm:CreateSequence>
</soapenv:Body>
</soapenv:Envelope>0
I have entered the wsa adress into my web browser
(http://129.183.18.65:6060/axis2/services/__ANONYMOUS_SERVICE__/__OPERATION_OUT_IN__)
and I get the following SOAP message :
-

Does anybody knows why I am getting a NPE into CallbackReceiver ?
I tried to debug axis2 into eclipse but I never reached the breakpoint I
put on the line 32...
Can you help me please ?
Thanks a lot for your answers.
Regards,
Charles

Hello
Tools use: Axis2 1.0, Sandesha2 1.0 and apache-tomcat-5.5.15
I'm trying to use the User guide example with the client
"UserguideClient.java" in sandesha2 1.0-bin.zip. I use the
RMSampleService.aar given in the Sandesha2-1.0-bin.zip. When I launch
the client, it could never get a connection to the server. In the
Console, I have no response. But when I have a look in TCPMon, I can
see the request "CreateSequence" was sent, because the client didn't
reveive the "ResponseCreateSequence". I tried to change the timeout
but it doesn't solve the problem, I think the connection to the server
is not available but the ERP is OK.
A moment later, the time out error appeared for all request
CreateSequence:
