Configuration for sync/async bridge in Jms adapter

Can someone give me a hint what I might be doing wrong?
The scenario is: synchronous proxy to jms.
Integration repository:
Created synchronous outbound interface and synchronous inbound interface, message mapping, interface mapping.
Integration directory:
Created jms receiver communication channel and jms sender communication channel and configured them according "How to correlate jms messages".
Created receiver determination, interface determination and receiver agreement.
No sender agreement necessary for proxy sender.
So far so good, but...
Both the receiver and sender jms adapter have its own queue (the receiving system will get the request in one queue and put the response in another).
How does the waiting jms receiver adapter know where to expect the answer?
When I test this scenario the (outbound) message get the status "Log version" (abap moni) and "To be delivered" (java moni).
PS:
The testing is performed by using the tool rfhutil. With this tool you can read and write directly from/to the MQ queues where the jms adapters are pointing to.
After receipt of the request in the queue of the reveicer jms communication channel, I manually put a message in the queue of the sender jms communication channel with the XI message ID filled in the correlation ID.

More information, In the jms adapter the following error appears:
XI inbound processing failed for message at time 2007-06-11|11:12:48.908+0100. JMS and XI identifiers for the message are ID:414d512052545849444556312020202045f55b6c20d73102 and 4e5bff20-1804-11dc-c2b4-00096b6ed15c respectively. The JMS adapter will rollback the database and JMS session transactions. If the session is transacted, the message is not lost and will be retried later. The exception stack trace is java.lang.Exception: Minimum address data not configured. Field InterfaceNamespace is empty.

Dynamic configuration in Sync/Async bridge in JMS

Hi
Scenario:
Portal sending request to JMS MQ and getting Response using sync/Async Bridge.
I have to written a UDF which will capture the value for cust_uid from request mapping and store it in dynamic configuration
And when the response comes from JMS MQu2026.this value gets populated in response mapping.
I have tested the UDF in a dummy Soap2rfc scenario and its working fine.
But when used in Sync/Async Bridge, the dynamic configuration fails.
For Sync/Async Bridge, there are 2 channels 1) Sender JMS 2) receiver JMS.
The synchronous request is converted to an asynchronous request in the module processor and sent.
The asynchronous system sends a response to a sender adapter. In the module processor of the sender adapter, this response is forwarded to the module processor of the original receiver adapter, where it is sent as a synchronous response of the waiting synchronous request.
Please suggest
Regards
Abhijit

Hi Abhijit,
Okay, so your data extraction/insertion is working fine for a simple synchronous request responser call.
I suppose this is working fine because your receiver adapter copies some part of the request message (at least the dc header) to the response message. (But I don't think this always works for all the adapter types). It is not working for the sync-async bridge because there are two unrelated messages in this case.
In order to copy the dc header from the first message to the second message, I think you can use the DynamicConfiguraitionBean module to store the dc header value in the module data and use this module again to recover it and set it to the second message. The whole process is somewhat complicated, but I will sketch the approach below.
First, let's call the first use of DCB the store step and the second the recover step. These store and recover steps must take place in the same module sequence so that they can use the module data to pass data from the first message to the second message. Furthermore, the store step must occur after the cust_id value is extracted into the dc header. So, your configuration must be placed in the receiver adapter side. Assuming the request message with the filled dc header coming into the module sequence, the first DCB module can be placed before the ROB module to store the dc header value in the module data. And the second DCB module can be placed after the WRB module to recover the dc header value from the module data and set it the dc header of the response message.
I hope this will work.

Sync/Async bridge via JMS with FAULT messages

Hello all, 
I set up a sync/async bridge scenario with using of JMS communication channel (SAP - JMSReceiverCC - JMSServer and application - JMSSenderCC - SAP). The normal communication works fine. 
But what we can not solve is the Fault Message handling. If there is a application error behind the JMS, a fault message is generated instead of proper application response and sent back to XI. Without any additional setup of JMS Sender CC the processing of the message ends with "MAPPING - EXCEPTION_DURING_EXECUTE", because normal "response mapping" is executed instead of "fault message mapping". This is correct behavior without any discussion. 
[SAPhelp|http://help.sap.com/saphelp_nw70/helpdata/en/45/202845de34072ce10000000a155369/frameset.htm] says that there are 2 module parameters to be set : fault, faultNamespace. The description is rather vague, so let's see, what the "NotifyResponseBean" does, when parameters fault/faultNamespace are filled: 
<pre>if(fault != null && faultNamespace != null)
if(faultNamespace.equals("http://sap.com/xi/XI/System"))
 ((XIMessage)message1).setMessageClass(MessageClass.SYSTEM_ERROR);
 ((XIMessage)message1).setError(fault, "no additional information");
} else
 ((XIMessage)message1).setMessageClass(MessageClass.APPLICATION_ERROR);
 ErrorInfo errorinfo = message1.createErrorInfo();
 errorinfo.setAttribute("ApplicationFaultInterface", fault);
 errorinfo.setAttribute("ApplicationFaultInterfaceNamespace", faultNamespace);
 errorinfo.setAttribute("ErrorCode", fault);
 errorinfo.setAttribute("AdditionalErrorText", "no additional information");
 message1.setErrorInfo(errorinfo);
} else
((XIMessage)message1).setMessageClass(MessageClass.APPLICATION_RESPONSE);
}</pre> 
The code is pretty straight forward so one could assume, that it's the name and namespace of inbound synchronnous message interface what is supposed to be filled in the values of each parameter. And from that kind of information SAP XI can evolve how to handle the response, actually the fault. 
Unfortunatelly the real situation is different - every time the fault message is generated and sent back to XI, the response is correctly corelated with the request message, "WaitResponseBean" and "NotifyResponseBean" are finished correctly and the processing crashes in messaging class on following exception: 
java.lang.NullPointerException at java.util.Hashtable.put(Hashtable.java:592) at
com.sap.aii.messaging.mo.MessageContext.setAttribute(MessageContext.java:140) at

com.sap.aii.af.ra.ms.impl.core.transport.http.MessagingServlet.doPost(MessagingServlet.java:337) at ...
 
Is there anyone, who can put more light on JMS sync/async bridge fault handling ???
 
Thank you ... 
Regards
Tomas

Hello again,
I proceed in investigation little more, but the main problem has not been solved. I found that the problem is not even in WaitResponseBean (placed in JMCReceiverCC). This bean is woken up properly on base of proper CorrelationID. See the log:
2009-10-15 11:00:33 Success WRB: entering WaitResponseBean
2009-10-15 11:00:33 Success WRB: retrieving the message for f1ea1fc0-b96d-11de-9b68-00144f4acd86 ...
2009-10-15 11:00:46 Success WRB: retrieved the message: ApplicationError
2009-10-15 11:00:46 Success WRB: leaving WaitResponseBean
I think, that the problem is somewhere within main messaging functionality. I suppose that on base of exception message:
com.sap.aii.messaging.mo.MessageContext.setAttribute(MessageContext.java:140) at
which is generated.
Any ideas or comments ?
Thank you in advance.

Is it possible to create soap to file sync/async bridge

Hi All,
I am balakrishna, I have one requirement, at sender side we have ep system and at receiver side having http system. from ep side we are using soap req/res as sync communication. At reciver side we have to use the reciver file adapter as a dummy because receiver file adapter doesn't pick the file from the http links. so, again we have to use the sender file adapter to pick the files (text/excel) from the http links directly using wget os command. how can i implement this scenario using bpm.

Hi,
You will find a sample BPM for sync/async bridge under
SAP BASIS --> http://sap.com/xi/XI/System/Patterns --> Integration Process --> BpmPatternSyncAsyncBridge.
Your requirement would be similar to this.

Getting Time-Out Error in Sync-Async Bridge

Hi All,
My IP has a Sync-Async Bridge. I have a fork, two senders, two switchs and a transformation step inside the bridge.
If XI takes much time to process the IP, the send step that closes sync-async bridge is not waiting for the message after a particular period and throws time out error to the sender.
Is it possible to increase the waiting time for sync-async bridge?
This IP works correctly 8 out of 10 times. Sometimes the message is sitting permenantly in the queue(smq2) and gives me system failure error.
Can u tell me why this problem happening?
Thanks & Regards,
Senthil.

Dear Michal/Senthil,
Can you pl clear a confusion that i have had for ages...
suppose there is a sync/async bridge ( i understand that it is used for sync business system too async BS communcation )
where we have 4 steps
sync receive - > async send -> async receive -> sync send..
i do understand that async send and async receive are combined through correlation
but i do not understand how do they work..
i mean when async send say send a file to a target system...does async receive reads a file from the same folder based on the corelation or wat...
basically can you pls explain me how do the steps 2 and 3 above work

Need help with scenario BPM Http-RFC Sync/async bridge

hi all!
i've got the following scenario: HTTP-BPM(XI)-RFC synchronous both of them. for that, i'm using S/A bridge in the BPM, but i'm getting the error 'Timeout condition of pipeline reached'. i think the problem is that the process gets lost in the sync/async communication, because in the trace level shows CL_XMS_PLSRV_CALL_BPE-ENTER_PLSRV" and after that every message are 'wait time starting'.
don't know the reason of the error. Maybe I missed something to configure?
the BPM is like this:
Receiver(Open Sync/Async bridge) -> Transformation (mapping from http request to RFC request) -> SyncSend (RFC request and response) -> Transformation (mapping from rfc response to http response) -> Send (Close S/A Bridge)
the IR is configured like this:

Businnes service VW -> created businnes service for HTTP adapter with interface mi_cxml_request_sync_out as sender. Comunication channel u2018HTTP Senderu2019
Receiver Determination
two receiver determinations. One for BPM and the other one for RFC(R/3):

hi all,
i've removed the transformations from the BPM, and i've created:
in IR:

                               receiver interface: mi_rfc_request_sync_abs
not sure these are the steps i had to do for mapping xml to rfc. but the result is the same error as before, the timeout.
i couldn't test with RTW because i'm getting an error 401 unauthorized.
i'd do it without BPM but the issue is that i wanted to add another step that would be to send the response from rfc to mail too once i got this BPM running. i mean, the response from RFC would be sent to http response and mail both.
the only way i can imagine to do it is with BPM but i'm really fed up with it.
thank u very much folks

Use of sync async bridge for webservices

Hi ,
We have a scenario where we need to send a data from ERP system to PI via webservice. PI communicates with a third party system via webservice.
The data can be posted to this third party system using webservices. The third party system then reads some data asynchronosly and sends the data to PI . We need this data to be sent to the synchronous webservice from ERP system.
Can we use the sync async bridge for this scenario. Some details on how we can do this will be very helpful..
Thanks
Bharathwaj

Hi Abhishek,
Thanks for the immediate reply.
The scenario is
ERP <---WS/SOAP--->PI -----WS /SOAP of 3rd party---> 3rd Party system (X).
PI <------- WS of PI
X posts the data to a backend. THe system X then picks some processed information. This system is not capable of sending the response synchronosly. It can post this data to PI once the data is available. Now PI needs to take this data and post it to the WS request from ERP.
Hope I have provided some clarity on the scenarion..
Thanks again.
Bharathwaj

Need help with Sync/Async BPM Scenario

I have an R/3 RFC -> XI -> HTTP (to vendor A) scenario that is working fine. It is a totally synchronous call event. The Integration Directory pieces sit in a scenario named HotkeyOutbound.
Now I need to create a process for RFC -> XI -> HTTP (to vendor Panduit). The R/3 RFC is the same sender, but vendor Panduit only supports an asynchronous HTTP connection. I followed the Sriram Vasudevan weblog on Sync/Async Bridge and created my BPM. I am stuck on trying to determine what to set up in the Integration Directory.
First off, should I be able to use the same HotkeyOutbound scenario as with vendor A so all hotkey stuff can stay together? Or do I have to create a new scenario with a copy of the R/3 business system for the sender? I moved forward with a new scenario (PanduitHotkeyOutbound).
I also need to know how many config Agreements and Determinations to use. The image at http://webpages.charter.net/kpwendel/keith1.html shows what I have so far. Which are not needed? What is missing?
And I tried setting up an HTTP communication channel for outbound async to vendor Panduit and another for inbound async from vendor Panduit. XI won't let me set up a sender HTTP channel. Why not?
Thank you in advance.

I have yet to figure this out, and probably need to go back to my Integration Repository setup since my problems may start there. This screenshot shows my Repository objects.
http://webpages.charter.net/kpwendel/intProcess.jpg
HELP! These are the steps I took, with questions embedded.
(1) Created data type and message type for xml document (note that same format is used for request and reply).
(2) Created PANRequestAbstractInterfaceSync (abstract and sync) for first part of Integration Process. Should the input message be the RFC or XML message type?
(3) Created PANRequestAbstractInterfaceAsync (abstract and async) for 2nd part of Integration Process.
(4) Created PANResponseToBPM_MessageInterface (outbound async) for interface back into XI from partner. Is this needed?
(5) Created PANHotkeySync_to_Async_IntProc Integration Process to handle sync to async bridge.
- Wondering why PANRequestAbstractInterfaceAsync is the only message interface available when I make container object (PANMessage)?
(6) Created two Message Mappings to handle RFC data to XML mappings (outbound RFC-> XML and inbound XML -> RFC).
(7) Created Interface Mapping that includes both the Request and Response message mapping programs from step six. Source is the RFC and Target is PANRequestAbstractInterfaceSync.
- Do I need another interface mapping with Source being PANRequestAbstractInterfaceAsync and Target being the RFC?
Link to these steps and app diagram:
http://webpages.charter.net/kpwendel/PAN_Hotkey_Diagram.jpg
Thank you very much for your time.

Sync async bridge configuration

Hi,
I am doing one sync to sync scenario using sync/async bridge in BPM,I am posting one message from HTTP client.
I am receiving the synchronous message inside bpm and opened sync aysnc bridge.
Then I need to do some transformations,
after transformation step I am closing sync/async bridge and sending the message back to sender system.
I have created repository objects,
while configuring directory objects,
I have run wizard once between sender and BPM and do i need to run wizard again?
please explain me about configuration (ID objects)?

BPM Design using sync-async bridge

Hi Arpit,
Below mentioned is an overview of the process flow which we are trying to implement.
1. A synchronous interface takes in the request
2. After the mapping, a file is created
3. Another file adapter reads this file and sends a message back to the sync interface. This step is to make sure that the file is created
I'm using a sync-async bridge for this process, since file creation and reading processes are asynchronous and the request/response is synchronous.
Can somebody help me by telling how to design the BPM. How many send and receive steps are required etc?
Thanks,
Sandeep

Hi
>>I have to map the incoming xml from HTTP to another format before creating the file.
Ya then u can use the transform Step in between the
sync Recv ---> Transform ---> Send to File System
>>Once a file is read, that interface has to send an acknowledgement message telling the status.
Wht type of acknowledgement msg telling the status.
I think u can add another element in ur created file payload like Status: Created (ConstanT)
Then u can map the payload of the readed file with tis payload having Ststus init.Fo this u need a Transformation Step.
BTW i was searching some previous blogs and i got this and it is bit related to ur scenario.Go thru this

BPM - Receive Sync/ASync Bridge Problem

Hi,
I am creating a scenario for an inbound Synch request to be serviced by a BPM process.
Here is the problem that I am facing while trying to configure the Receive Step
- I created a Message Interface defined as Abstract Synchronous.
- I created a process model and put in a Receive Step: Mode - Opens S/A Bridge, Synchronous Interface - defined as above.
- I define a container with Abstract type. But when I try to locate the above defined Abstract Synch message interface, I cannot find it.
- As a workaround, I create another Abstract Message Interface defined as Abstract ASynch.
- I create a container with this Abstract ASynch message type.
- I use this container in the Receive Step.
But activating the Business Process gives the error:
Message to be received and Synchronous Interface do not have identical types.
Can someone give me the correct procedure to configure the Sync / ASync Bridge ? thanks,
-Manish

Double Sync-Async Bridge

Hi guys,
One simple question:
Is it possible to have two S/A Bridge in a single BPM? It should be quite simple.....
Thanks in advance

Hi,
You are right in real time this will be not possible to even use the two S/A in one process.
But you could design the process in such a way that
lets assume you have one sender A and two receiver B & C
A--Synchronous
B---Async
C---Async
Now the scenario is like
A-request -
> B as well as for -
> C.
here B is async so you need to built A to B as S/A bridge but as I had said simultaneously it need to send the data to C which is also async then you need to use Fork to create two branches one for B and one for C.
Here you need to create Dummy response for A as B or C will not send any response.
This scenario is very rare to be practical..but there is chance that you could design it in BPM.
I am pretty sure about the scenario will not work successfully as there will be 3 ports opened at a time and multiple resources will be consumed.
1. Define a Receive Step to Open the Sync/Async Bridge
2. Define fork with 2 branch one for A and one for B
-One Branch-
Define an Asynchronous Send Step for B
Define a Receive Step for B
-2nd Branch--
Define an Asynchronous Send Step for C
Define a Receive Step for C
4. Define a Send Step to Close the Sync/Async Bridge
Here if you see you have two Sync/Async bridges one for A to B and another for A to C.
I never have implemented it just giving you the hint.
Thanks

REG : SYNC/ASYNC bridge

Hi all,
I have a scenario where my sender is a syncronus and receiver is asyncronus. I have used sync/async bridge in BPM to acheive this.But when i send the input data from runtime workbench with QOS as BEST EFFORT i got the following error " Error While sending the message". When checked in moni, the data has sucessfully sent to the receiver and in the BPM flow is failing at the last step (ie SEND step which sents syncronus respose and which ends the bridge)
The steps i used in BPM are
RECEIVE(start of sync/async bridge)--> SEND(which sends data to receiver)--
>SEND(which ends the sync/asynbridge) The response that i send is same which i receive(input data) , so i didnot use any step for response .
I ran the wizard for 2 times :
1) from my source to BPM in which is syncronus.
2)from BPM to receiver which is asyncronus.
Can anyone please provide me solution for the above problem.

Hi Srinivas,
In BPM second step,
Send step it would configure the properties as a " Synchronous". then only response back to the sender.

sateesh
