Handling end dialog message in async trigger scenario

I have ServiceA which send message to Service B. Service A lives in a sql trigger and doesn't wait for a response from Service B. Service B pulls the message off the queue and closes the dialogue. This generates an End Dialog message that
was intended for Service A but Service A has long since moved on. Is it ok for service B to subsequently process the End Dialog message in this scenario?
Service A context = Sql Trigger
Service B context = .NET windows service manually calling TSQL Receive

For 10-20 times a day, it seems an overkill to reuse conversations.
Guess I could have an activation sp look for EndDialog messages and close them and skip all other message types (the rest would be de-queued / processed by the windows service).
Nope. You should only see the EndDialog messages. Keep in mind that this is the queue for the
initiator. The Windows service should not touch this queue. It should read the target queue.
You should really only see EndDialog messages on in that procedure, but there could be error messages as well. It can be a good idea to log these somewhere, to make troubleshooting easier.

How to handle duplicate messages in J2SE File scenario

Hi,
Is there any way to handle processing of duplicate messages in J2SE File adapter scenario?
Here is the scenario ,
Steps :
1. Engine picks up a message and checks the size of it.
2. Before reaching the checking interval , the adapter(file) was terminated unfortunately.
3. J2SE engine was restarted.
4. Previous file was again picked up and sent as the first time with one msgID.
5. After sometime, same file was picked up with a new msgID
6. System gets only ONE configrmation that file has been successfully transfered.
So we find two messages containing the same file.
I have checked in J2SE doc, there is a parameter called "db.exactlyOnceErrorInPendingState" which is related to DB.
Is there any similar parameter to handle the duplicate messages in FIle Adapter scenarios of J2SE Engine.
Please help me in this regard as it seems to be a new thing in J2SE AE.
Regards,
Soorya.

Handling SOAP Fault messages in BPM

Hi,
My scenario is Sync-Async Bridge involving File to SOAP transformation. I have used BPM as 1 file has many records and each record is required to call the web service synchronously.
In the BPM I have
Receive ---> Transform (1:n multimapping ) -
> Block (Par for Each)
In Block I have Send Sync step to call Web service . I have an exception branch for the send step for catching Fault message that is sent back from webservice for Application Fault.
Problem:
Though the Fault message is sent from web service ,in the BPM the block goes in error saying : "No exception defined for fault message ". The Exception brach is not executed.
Please suggest if anyone has come across such a scenario and solution to this.

hi satesh
using "exception handler" in BPM we can handle the error messages

Error Handling and Error Messages

I already posted this in the java programming forum, but I dont think the people responded understand patterns, or what I was asking. Here is my original post, for reference I am not asking how to catch and exception, or how to display an error, I am asking about the pattern implementation.
I am currently in the process of creating my Exception model for my program, and I have a question about error messages. I was reading the book "Effective Java Programming" which deals with patterns and it states that an exception should state the error and report information on all relavent states. For instance If you have a class the modeled some sort of memory array, and an access was requested to a block of memory outside the array you should throw an ArrayIndexOutOfBoundsException("Index:" + index + ", start:" + 0 + ",end:" + Array.length) or if you made your own MemoryAddressOutOfBoundsException(same as above) which when printed should read
ArrayIndexOutOfBoundsException: Index:-1, start:0, end:0
stack trace
The pertinate information is the index, start index, and end index.
The book CLEARLY states as an industry design pattern that exceptions weather checked or unchecked should not contain user error messages. For instance with the above example one might be tempted to use this as the exception message: "The memory addres index is not a valid memory address." This is clearly a user error message.
So heres my situation. In a gui environment (command line console not visible) how do you generated a user error message, letting the user know that an internal exception has occured.
In my previous implementation of my project, I used the exception message the user error message and just reported the message on a dialog. I have heard of people using error catalogs, which centrallizes all the error messages into a single class or file.
I was wondering if and Error catalog was a good approach, how I might go about implementing one, and if not how do you the community handle user error messages.

class MyAppErrors {
   public static final int FILE_NOT_FOUND = 0;
   public static final int DIR_NOT_FOUND = 1;
   public stat final String[] errMsgs = {
      "The file was not found.",
      "The directory was not found.",
   public String getErrMsg( int n ) { return errMsgs[n]; }
[\code]
And a nicer version would allow the calling code to pass in a substring so you could say "The file 'somename.ext' was not found."

Handling Multiple Error Messages through EXIT_SAPMM06E_012 for ME28

Dear Team,
After Executing ME28, system will give List of PO's that are to be Released . User will select Multiple PO's and
Press Release button in Application toolbar. once it is relased, User will press save Icon for all released PO's.
Once Save icon is presed, I need to do Validation for Multiple PO's in the user Exit EXIT_SAPMM06E_012 and capture my
ErrorMessages for all Released PO's for which Validation fails.
Here in the given user Exit, one PO will be processed at a time as PO is defined as Import Parameter but it will handle all PO's
and give the output in status bar saying 'Relased Saved' for all PO's which succesfully gonethrough.
once we execute ME28, system is showing list output with PO's to be Released(As system is handling with Write statments). In this case, we dont have scenario of PBO and PAI Modules( where user can correct error if any validation fails) like we have for ME22,etc.
I have Written simpel Error Message in the User Exit.
once i tried to trigger my user exit by Releasing and Saving with One PO, Error Message is displayed ( as information Message
appears) and if i Press Exit button in Error Message, it is coming out of Transaction.
Is there any Possibilty to Handle Multiple Error Messages ( in my case for Valdiation Failed Po's) in ME28 ,after Releasing and Saving , and also user should not come out of Transaction once Error Messages are Displayed.
Thanks and Regards
Suresh

Hi Suresh,
there is a tekpo table to handle all po items. you can put it in loop and do validations.
if any errors through, there may be a ex_messages table of type bapiret2.
or
try like this: MESSAGE E368(00) WITH TEXT-001 TEXT-002.
thanks

Missing response message in Idoc - WS scenario

Hello
I 'm missing a response message in the follwing scenario:
Idoc-> XI -> Web service (SOAP)
A Matmas idoc is sent from R/3 to XI. In XI the Idoc is
mapped to a SOAP message and sent to a web service.
The Message Interface for the SOAP call is synchronous
and has a PushMaterialSoapOut and a PushMaterialSoapIn
messsage, which is defined in the WSDL from the
web service and imported into XI Repository.
Everything is working fine but I do not get the response
message. The web service has sent the response message. I
have traced the firewall logs and i have seen the
response.
What is wrong? Is it basically possible to have a
scenario like this?
The message must have arrived somewhere, since the web
server does not throw an exception. But where is it?
Thank you in advance
Thomas

Hello Stefan
>Scenarios with IDOCs are always async. Therefore you
>cannot have a response.
Ok, so I have to use BPM.
>How do you want to process the response? What should
>happen in the sender system?
I was thinking about an ALEAUD idoc which is sent back
to R/3. Therefor I have created an synchronous message
interface with the MATMAS idoc as outgoing message and an
ALEAUD as incoming message. Accordingly I have a message
mapping for the response message.
An other reaction to the response message could be to set
the message to status failed. But this is the next issue.
>In some scenarios you might use a BAPI instead of an
>IDOC for synchronous message processing, but this
>depends of many circumstance depending ofyour business
>requirement.
The process in SAP R/3 is fixed. To move to BAPI is not
an option.

Sync/Async BPM scenario : Problem at Integration Process..!!

Hi All,
I am doing Sync/Async BPM scenario.
start ->Receive(Request)> Transformation(Responsemap)>Send(SendtoR/3)->Send(Send Response) ---> stop.
When Iam trying to Activate, Integration process giving errors as
Source parameter AA_Payment_Req | http://XXXXXXXXX.com/SAP_PI/DirectSales/Payment not set Target parameter AA_Payment_Response | http://XXXXXXX.com/SAP_PI/DirectSales/Payment not set
Warning: Container element Response is defined but is neither initialized nor used.
But I am using them in the BPM. The same kind of scenario is working for another interface which is already running in production. When I tried to check that interface it is showing only Warning message as Container element Response is defined but is neither initialized nor used.
I tried deleting and creating again and still it is showing the same error.
Can anyone please suggest what might be the problem.

How to know what link is clicked on a Balloon tooltip after handle the TTN_LINKCLICK message ?
MCunha

Basically you don't know what link was clicked. If you need more than one link, you may need to use a different UI element to display it, like a dialog or some sort of other popup window that you have control over.

These things will happen in the same page. I have tryed to know the any Id/Name of error message.
So please help to handle error and skip that error then continue execute raming code.
Thanks

A few problems with this question that need clarification:
You're using a GUI, but we have no way of knowing which one -- Swing? AWT? SWT? other?
You ask how to fix your program flow and logic but don't show us the current state. Most of us can't read minds so a bit of code would be nice here.
You mention "Page". What context is this in?
A great resource that has helped me and will probably help you is an article entitled [How To Ask Questions The Smart Way|http://www.catb.org/~esr/faqs/smart-questions.html] . It will tell you how to formulate your questions so that the folks here will be better able to answer them. Good luck.

BufferReader using reaLine() is not terminating when end of message.

Hi folks,
Newby Java here. I have a situation where I am writing a Server Socket Java program where I am accepting connection from a client and the client is sending messages me. I am able to connected to the client and the client successfully send messages to me, but the problem I am running into is that it's not terminating the while loop when I read to the end of the message using a reaLine(). It's like it's hung up or something...
Here is a copy of the code.....
ss = new ServerSocket(6500, 5);
System.out.println("Listenning........waiting for connection from client");
try {
response = ss.accept();
System.out.println("Accepted connection from client");
InputStream in = response.getInputStream();
System.out.println("Input Stream Opened");
BufferedReader br = new BufferedReader(new InputStreamReader(in));
System.out.println("Buffered Stream Opened");
System.out.println("Server received: " + "\n" );
BufferedWriter bw = new BufferedWriter(new FileWriter("testing001.txt"));
String input = br.readLine();
while (input != null) {
bw.write(input);
bw.newLine();
input = br.readLine();
br.close();
bw.close();
System.out.println("Done receiving message" + "\n" );
OutputStream out = response.getOutputStream();
BufferedWriter buf = new BufferedWriter(new OutputStreamWriter(out));
buf.write(result);
System.out.println("Server sent: "+result);
buf.flush();
buf.close();
response.close();
ss.close();
catch (IOException e) {
System.out.println("Failure accepting connection: " + e);
What am I doing wrong that the while loop does not terminate when it reads to end of the message using this "readLine()"?
It does not execute the next statement after the while-loop unless you disconnect the connection from the client.
Help!

readLine() will wait for more lines forever, or until the other end closes the connection. (For completeness: there are other termination situations too, mostly error conditions.)
You have a multi-line message? Send some kind of an end-of-message line and check for it in your read loop. E.g. "." on a line all by itself. Caveat: if the message itself can contain a line like that you'll need to quote that line somehow. Another approach: send the number of lines in the message first. Requires that you know the number beforehand.

How to retain the dialog messages defined in processRequest after rendering

In my page one piece of code is there as "oapagecontext.forwardImmediatelyToCurrentPage(null,true,null);"
which is used to render back to the current page,but after rendering the dialog messages which i have defined in processRequest are not coming.
My issue is how can i retain that dialog message.

Hi
You can try and use guard conditions or check the table for data, if there is no data in the table the application will return an error message.

"Always insert attachments at end of message" doesn't stay checked? How to make it stick?

I check "Always insert attachments at end of message" but it doesn't stay checked over time. Any suggestions?
Thanks.

Are you checking it while composing a new message? If so, that only sets it for that message. If you set it without a new message, it should stay set.
If it is still not staying set, it could be a problem with the Mail prefs.
