Question

Hello friends, since 4-5 days i am stuck in acheiving R/3 -> XI -> R/3 scenario.
Today i found this Messaging system Monitor, where i can see my requests under Sent Messages -> Synchronous
looking at the Audit Log can you please tell me whats going wrong.
Success RFC adapter received sRFC for BAPI_USER_GET_DETAIL from TTD/000. Attempting to send message synchronously
Success Application attempting to send an XI message synchronously using connection AFW.
Success Trying to put the message into the call queue.
Success Message successfully put into the queue.
Success The message was successfully retrieved from the call queue.
Success The message status set to DLNG.
<b>Error</b> Returning synchronous error notification to calling application: Received HTTP response code 404..
<b>Error</b> Transmitting the message using connection <b>http://ps3181:50000/sap/xi/engine?type=entry failed</b>, due to: Received HTTP response code 404..
<b>Error</b> The message status set to FAIL.
2006-06-26 18:05:03 Error Returning to application. Exception: Received HTTP response code 404.

these are Message Details , if you notice <b>To Service</b> is not showing any value , why is it happening as i have configured the receiver in Integration directory
since 4-5 days i am getting "call to messaging system failed. com.sap.aii.af.ra.ms.api.DeliveryException"
also the audit Log spoke something about this <b>http://ps3181:50000/sap/xi/engine?type=entry failed
, due to: Received HTTP response code 404.. </b>.
what oes this mean , when i copied this url to explore , i get message saying "Page Not Found"
Please reply if anyone of you have encountered this problem earlier

Hi Krishna ,
i made the Pipeline URL with Port 8000.
No in the error log i am getting following error
2006-06-26 19:24:29 <b>Error SAPEngine_System_Thread[impl:5]_94 1151330069023 Returning synchronous error notification to calling application: Received HTTP response code 403..</b>
2006-06-26 19:24:29 <b>Error SAPEngine_Application_Thread[impl:3]_17 1151330069023 Transmitting the message using connection http://ps3181:8000/sap/xi/engine?type=entry failed, due to: Received HTTP response code 403..</b>
when i tried accessing same URL directly in explorer it says " Service cannot be reached : URL http://ps3181:8000/sap/xi/engine call was terminated because the corresponding service is not available.
<b>Note
The termination occurred in system TD1 with error code 403 and for the reason Forbidden.
The selected virtual host was 0 .</b>
What does it show to you all when you try accessing same URL , should i get something , is there a problem in some configuration in my XI..
A little details about my configuration
in exchange Profile  :
com.sap.aii.connect.integrationserver.r3.httpport = 8000
com.sap.aii.connect.integrationserver.name = ps3181
com.sap.aii.connect.landscape.httpport = 50000
As i said earlier , while creating business system
my URL is http://ps3181:8000/sap/xi/engine?type=entry
however in XI BOx when i say sxmb_adm->Integration Engine Configuration-> Check . In system landscape it shows http://ps3181:50000/sap/xi/engine?type=entry
and most importantly SXI_CACHE not working in XI .
Can you please tell me where is the error.
Thanks
