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 communication in JMS adapter without BPM

Hi,
as of SP19 XI's JMS adapter offers this new feature for Sync/Async communication through JMS Adapter modules instead of using a BPE.
Now I would be interested to know if anybody has already successfully used this feature especially using WebSphere MQ as a JMS Provider (preferredly in the mode JMS Compliant: WebSphere MQ (non-JMS)).
I experienced some issues with the XI Message ID being used as the JMS Correlation ID which is then mapped to the MQ Correlation ID being truncated after 24 characters. So I don't exactly know whether this is due to wrong setup or some general issues with this messaging system.
Please let me know if you have any experiences at all with this new feature (please do not just post links to the following blogs, which I have thoroughly studied as well as the How-to Guide concerning this topic)

Hi Peter,
we working on the same Problem. Using IBM Websphere MQ as JMS Provider for the new feature: sync/async bridge without BPE.
we switched on a high level trace for the adapter framework and saw a problem in the receiving Object of the JMS correlation id. The notify bean receives the JMS correlationid in hex format. so the beans have two different correlations, which could not find together.
did you have any solution to get this new feature works with IBM Websphere ?
thanks

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.adapter.xi.ms.XIMessage.updateHeaders(XIMessage.java:4244) 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.

Tomas

SOAP to JMS using Sync/Async bridge - configuration confirmation needed

Hi group,
Since I'm experincing error in a scenario using sync/async bridge in jms adapter I really would like a confirmation on my configuration.
For a simple SOAP to JMS scenario is it then correct that all I need is;
1) 2 synchronous message interfaces, 1 inbound and 1 outbound
2) 1 Receiver determination
3) 1 Interface determination
4) 1 Receiver agreement (JMS adapter with module configuration)
5) 2 Sender agreements (in my case 1 soap and 1 JMS adapter - the later with module configuration).
6) The sender and receiver JMS adapters point to different MQ queues (request and response queues)
7) The sender agreement for the JMS adapter uses my synchronous, inbound message interface (isn't this really just a "dummy" to actually fetch data from response queue - meaning that the actual utilized business system/service, MI and namespace are unimportant, since the module will make the adapter notify the listening module in the receiver JMS adapter?)
Best Regards,
Daniel

Hi, thanks for your reply.
I'm familiar with the links provided. I believe everything is configured as it should be, but since I get error I would like to have my configuration confirmed. Neither the weblog (or SAP guide) are detailed enough to convince me 100% that my configuration is correct. Surely the problem could be on the MQ side, but before going into that, I want to be sure that its not on XI-side.
So I really would like confirmation on the steps/question that I wrote:-)
Best Regards,
Daniel

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

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.

Sync/Async Bridge without Asynchronous Send / Receive Steps

Hello together,
we have a synchronous HTTP <--> RFC Scenario using a sync/async Bridge in BPM with the following characteristics:
1. HTTP Payload is received (opens Sync/Async bridge)
2. lookup is done in an LDAP System (we use an UDF here)
3. Customzied JCo is called which takes the XML String as input parameter (done by Java Mapping)
4. Return Value of JCo then is delivered back to HTTP Client (closes Sync/Async Bridge)
--> No RFC Adapter is used here as the provided JCo does all the parsing
When testing the sync/async bridge is started but we receive an timeout after 30 sec.
Could it be that the sync/async required exactly a pair of async send and receive steps (which we do not have in our scenario and which we do not need)?
This would be a problem, as we have to use BPM in this synchronous scenario. Do you have any idea?
Thank you very much for your help.

Thank you for your reply, but I think you misunderstood me. Please let me try to clarify once more:
1. Synchronous HTTP Sender Interface (Request/Response) opens Sync/Async Bridge
2. LDAP Lookup is done by UDF using the Request Message in Transformation Step
3. Switch is done based on result of Lookup
4. Branch 1 in switch calls customized JCo with Java Mapping in Transformation Step (Request Message as input, Response message as output)
5. Response message (delivered from JCo Call) should close the Async/Sync Bridge and be send back to HTTP Sender
--> We have no async send / receive steps in this scenario.
The customized Jco has been provided by an external partner as there is lots of parsing logic implemented. So we want to connect to the backend SAP system using this JCo and not via a send step.
My key qestion is therefore: Is it absolutely necessary to use exactly a pair of async send / receive steps in a sync/async bridge?
In this case we have to look for another design concept without BPM which would make the solution very difficult I think....

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

Sync/Async and Async/Sync Bridge in JMS Adapter

Hi,
I have scenarios using both the Sync/Async and the Async/Sync Bridge in the JMS Adapter. In general this works fine. There is just one thing that caught my attention.
In the Sync/Async Bridge, the correlation in JMS is done
JMS Message ID of Reqeust --> JMS Correlation ID of Response
In the Async/Sync Bridge, it is done
JMS Correlation ID of Request --> JMS Correlation ID of Response
which seems strange as I would have expected to work the same for both ways...
I'm following exactly the setup described in the 'How-to correlate JMS' guide.
Has anybody experienced the same thing or am I missing something important here?
thanks for your help
regards,
Peter

Hi,
If I get it right the MQ queue gives a response message back to XI. The message looks okay on MQ queue, but in XI it's empty.
So I guess the problem must be within the channel that picks it from MQ queue. Did you configure any modules in it that might screw up the content? Is the the message empty as soon as it arrives in XI adapter engine? Pls. check in RWB Monitoring or End-to-End monitoring.
Do you have other channels that pick up messages from that or another MQ queue which do not show such an error? Are they configured exactly the same way?
Regards,
Kai

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)?
Thanks

RFC -File Sync Async bridge RFC Adapter Exception

Hi
I am using sync async bridge to send a response back to rfc.
Although there is no error in sxmb_moni as well as the auditlog shows that the response was sent successfully to rfc.. still the RFC adapter gives the following error with no response sent to RFC..
Error in processing caused by: com.sap.aii.af.rfc.RfcAdapterException: failed to identify XML document:java.lang.Exception: javax.xml.parsers.FactoryConfigurationError: Provider com.sap.engine.lib.jaxp.SAXParserFactoryImpl not found
please help

Solved the problem..
The problem could be due to the following..
1. the response structure was just a single character..while i was sending a whole string..
2. I restarted the server...probably the problem
javax.xml.parsers.FactoryConfigurationError: Provider com.sap.engine.lib.jaxp.SAXParserFactoryImpl not found
system property must have set mismatch for the SAXFactoryImpl.... by deploying modules before in which i was using SAX parser.. may be the i set the system property earlier to other provider dont remember...
Hope this information will be useful to someone in future using Sync/Async bridge
