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

Async/Sync Communication using JMS adapter without BPM

Hello ,
Pls suggest how Async/Sync Communication using JMS adapter without BPM .
In my scenario I have JMS Sender and then RFC/JDBC as Sync and then again JMS receiver
Pls explain the concept of
JMSMessageID and JMSCorrelationID and how to use it by an example.
Regards

Hi,
If you have selected JMSMessageID, JMSCorrelationID, or JMSProperty and entered a JMS message ID in these fields, you should see the Remove 'ID:' Marker from JMSMessageIDindicator. Set the indicator.
This is necessary because the JMS specification stipulates that each JMS message ID starts with 'ID'. However, this conflicts with ISO-11578.
- JMSMessageID (Uniqueness Is JMS-Provider-Dependent)
(String) The unique message ID. Note that this is not a required field and can be null. Since the JMS provider might not use your provided message ID, the Connector sets a special property called $jms.messageid after sending a message. This is to insure that the message ID always is available to the user. To retrieve this value use conn.getProperty("$jms.messageid") in your After Add hook.
- JMSCorrelationID (Uniqueness Is JMS-Sender-Dependent)
(String) This header is set by the application for use by other applications.
Hope this will help you.

Sync/Async communication with JMS Receiver

Hi all,
I am working on one Sync/Async model without BPM. Sender is RFC which is expecting some response, but we know receiver jms doesnt support response message directly. For this i used modules provided by SAP.
While developing interface i used below objects.
One Outbound Synchronous interface--> for Sender RFC channel
Inbound Synchronous Interface----->for Receiver JMS Channel
outbound asynchronous interface--->for Sender JMS channel
one request mapping and one response mapping
Operational mapping between outbound Synchronous to inbound synchronous.
ID Objects:
2 sender agreements: one with sender jms channel
one with sender rfc channel
1 receiver agreement: with jms receiver channel
1 receiver determination
1 interface determination
In receiver jms and sender jms channels i used modules as specified in the document http://help.sap.com/saphelp_nw04/helpdata/EN/45/20d2b4c20a0732e10000000a155369/content.htm
But my interface is not working end to end successfully.
Please confirm below points
1)do i need to have other external application put response message to response queue or will the MQ automatically generates the response message and put into response queue
2)In receiver jms channel is it ok if i will put response queue(Q2) name in the field JMS ReplyTo Queue Name or do i need to put in the form queue://<ReplyToQMgr>/<ReplyToQ>
3). what is the format of data type for asynchronous outbound interface which i used for sender agreement of jms sender channel.
4). Do i need to do any other special settings at MQ settings in MQ server.
Note: i am using PI7.1 and i selected the option JMS-compliant for target client in jms channels.
Thanks,
Madhu

1)do i need to have other external application put response message to response queue or will the MQ automatically generates the response message and put into response queue
The following information is available in SAP note-
Message correlation implies correlating a response message with a request message. With respect to the JMS adapter, this means that you sent have sent a message through a JMS receiver channel to some JMS queue (say queueA) , some external application processes this message and puts the response onto another JMS queue(say queueB) which is then picked up by a JMS sender channel. You need to relate this response message with the original request message.
In the simple case, for all JMS compliant providers this can be done in a straightforward manner:
a) In the JMS receiver channel configuration, set the JMSCorrelationID to the XIMessageID. (or some other XI header which is applicable)
b) Ensure that your external application does not change the value of the JMSCorrelation
c) In the JMS sender channel configuration, set the XIConversationID to the JMSCorrelationID
d) The XIConversationID header of the response XI message now contains the XIMessageID of the request XI message.
For some providers such as Websphere MQ in legacy/native mode this is not so straightforward.
Do i need to do any other special settings at MQ settings in MQ server.
If your using Websphere MQ, refer que#4 in sap note :1086303

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.

Send attachment via Receiver FILE/JMS adapter without using any Mapping.

Hi,
R/3 program creates one (encoded) text file, which I want to send via Proxy to JMS adapter without any mapping or FCC.
Note: I don't want to use File adapter to pick the file from R3 dir and then send it to JMS.
Reference: I have gone through below mentioned blog which produces the attachment in the XI payload but I am not able to write the same attachment to my XI dir using Receiver File adapter (File adapter is just for testing actual adapter will be used as Receiver JMS adapter).

Regards,
Sarvesh

> note sure why you want to complicate things here
Actually the idea was to explore the possibilities of "Proxy with attachment". And I also wanted to confirm with experts like you before going to other options. Anyway it seems it's only possible with mail adapter.
Reason for exploring above possibility: Since ABAP team has to create one text file and encode it, so we thought to call the outbound proxy in the ABAP program to send the same file as an attachment and then simply send it to JMS. Which is quite obvious thinking when you don't want to manage a share directory between R3 & XI or don't want to manage FTP user and pwd.
> i think the simplest thing is to go for a simple file to jms configuration unless you have any specific reasons for not doing so.
This we already kept in our mind as a last option in case if above thing is not possible then we can easily do it by this way.
Thanks a lot for suggestion.

Sarvesh

Sync-Async communication

Hi!
Is it possible to have a sync-async communication like this:
receive - open s/a bridge
send (async idoc with acknowledgement in return)
send - close s/a bridge?
or do I have to use a receive step after the send step in the middle?
I am trying to get a confirmation of Idoc posted to application and send this back to calling application, but I get a timeout error after the send (async idoc with acknowledgement) step...
Thanks!
regards Marianne

Hi
Thanks for you answer. I trust you here, but I have seen someone using this approach here on sdn.
Is it not possible to have the send step wait for acknowledgement and if ack is received then send a message back to the synchronous process. And also have a timeout exception that sends back a fault if acknowledgement is not received?
I know that some have been able to return to sync process wether the Idoc was posted correct or not...
regards Marianne

The message sequence of JMS adapter and BPM

This is my scenario: AP1 -> MQ -> JMS Adapter -> XI BPM -> SAP
But if AP1 sends 10 messages to MQ server, how to make sure the received message sequence of SAP is the same as AP1 ?
Because JMS adapter doesn't have synchronous ability, or I can set best effort to make sure the sequence.

Monitoring inbound processing and Sync/ Async communication on PI7.11

Hi All,
I am new to PI. We have following two requirements to be done on PI 7.11
1)     Monitoring inbound processing (Txn Code SWF_INB_MON)
2)     Monitoring Sync/ Async communication (Txn Code SXMS_SAMON)
Kindly let me know how should I proceed or what document should I follow or any scenario is to be configured.

Hi,
    1. Start inbound processing monitoring with transaction SWF_INB_MON or SWF_INB_ADM.
           Note that you require administrator authorization for transaction SWF_INB_ADM
    2. You can monitor the throughput of the inbound processing either on the basis of individual process system or system-wide. In this way you can display the throughput figures in any discrete time range, right down to seconds. A similar display for message packages allows you to monitor inbound processing with the same detail."
     3. You can display runtime information about individual messages, for example, the total runtime of a message in inbound processing or just the runtime of a specific section of the inbound processing. For monitoring individual messages click on "Display Message Packages".
regards,
ganesh.

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.
Regards
Tomas

JMS adapter and BPM

Hi.,
I would like to know if it is possible to use SAP XI3.0 BPM and JMS Adapter for synchronous messaging? Scenario is like this: webapplication-->MQ Series --> xi ---> database. And in reponse message we got to have MessageID, Correlation ID and Reply to Queue name and Queue name Manager. If we could do this, can anyone share some informatino on this topic. From my knowledge i would say yes, but i would like to know exact approach(BPM steps, Configuration steps).Thanks for your time.

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.

Synchronous communication of JDBC adapter with BPM

Hello XI-Experts,
Could you please give me example where BPM is having a Synchronous communication with JDBC adapter??
plz do help.
Thanks & Regards,
Vanita

Vanita,
Let's consider the below scenario.
A File contains the SQL query, you need to fetch the data from DB system using that SQL query and write it to a file. You can configure like below
File Adapter to pick the file and send it to BPM
Mapping Transformation to create the SQL request
Call DB using JDBC adapter Synchronously
Mapping Transformation to Convert the Response from DB and write it to a file.
Does it seems to be a valid scenario you are looking for? Any questions let us know.

Async-Sync Bridge without BPM for SOAP WS and JDBC

I heard you can now have async-sync communication outside of BPM by utilizing adapter modules?
My scenarios are:
proxy (async) -> SOAP WS (sync)
proxy (async) -> JDBC (sync)
I will like to capture the synchronous responses in XI and perform some basic error handling.
I read h[File - RFC - File without a BPM - Possible from SP 19.|File - RFC - File without a BPM - Possible from SP 19.] and the release notes for 2004s SP19 and there is no reference to JDBC or SOAP.
