Best Pratice of Error Handling calling multiple external components

I have used EJBs in my question, but it applies to any component/service that is exposed.
If I have EJB1 calling EJB2, what is the standard approach to handling an error received from EJB2? Does EJB1 simply pass it back or wrap its own error around it?
I use the term error to include exceptions & all information that would be used for debugging & used by the caller.
If we allow the errors from EJB2 to be returned to the caller of EJB1, then the caller of EJB1 must be aware of those errors.
If EJB1 wraps the errors from EJB1, then the caller of EJB1 only needs to know about errors returned from EJB1.
This can be extended a little and EJB1 calls multiple ejbs. Some of EJBs may be external EJBs or have the possibility of returning an error from a 3rd party tool.
What should be returned if EJB3 can return the same error as say EJB4? If (for some reason) the caller needs to know exactly when the problem occurred it would imply that additional information needs to be attached to the original error.
What would be a 'best practice' approach to returning the errors to the original caller?

Caller?
EJBs are in a layer. For application programming layers will seldom return errors (plural) to other layers.
Within a layer handling depends on the context.

What is Considered Best Practice for Error Handling in Components?

What would be the best approach to handling errors in custom (possibly composite) components?
I see three different possibilities:
Having the error handling funciton within the component. The problem is that this is not adaptable to the consumers error handling setup (i.e. logging to database, redirecting to a pretty error screen, etc.).
Passing in an error function as a parameter. The problem here is how to have the externally defined error function interact with external elements that are not defined within the component, i.e. passing the error or fault object to a logging class, or something similar, of which the component knows nothing about.
Referencing the external error handling methods directly from within the component. (Of course that's shabby programming, just listing as a technical option.)
How do you solve this?
My goal is to have a versatile custom component that can utilize any given consumer's error handler.
Thanks,
Mike

or define a customized event and dispatch it when error occur, then you can just listen to it outside

Idoc/ALE error handling, send to external email

Hi all,
I'm developing an IDoc inbound interface for purchase order create using PORDCR1. For the error handling functionality, I need to send an external email describing all of the validation error happened in user-exit EXIT_SAPFKCIM_002. Please kindly tell me how to cater the functionality. I won't use workflow because the error handling can't describe all the error, it just displaying the first error encountered. I also don't want to create any custom object since message type PORDCR1 is available. I think creating a custom FM is a possible way, but if there is another way, please tell me how.
Thanks,
Teddy

Hi Teddy,
A custom FM is the easiest and simple way.There may be other ways.

R49 Communication error, CPIC return code 020, SAP return code 223
Can any one help me find wat might be the cause of this issue.We are using SAP R/3 and OS is AIX 5.3
Thanks,Rajesh

Dear Rajesh,
This depends on what your program does. Based on the error message, it looks like the program ends abnormally, as the gateway writes an error while attempting to read/write data from the connection to the program. With what you have given, the error does not seem to lie with the SAP side. You will have to check your program, e.g. using a debugger.

Error when calling an external web service (blank soap action)

I did a lot of searching on this message and did not find an answer. Most of the issues i found related to XI/PI, which we are not using.
There is a web service created outside of SAP for which i generated (from the WSDL) a proxy class in my DEV system, client 050, a few years ago. This was subsequently moved to QA and production, and all is working fine.
Now, i want the same web service to work in client 100. I created the logical port, and the RFC destination, but when i try to call the web service, i get the following error
Server did not recognize the value of HTTP Header SOAPAction
Since only the basis group around here can access the logical port definition,and rfc destination, i have no idea where this information should be set up. I should not have to reimport the WSDL, since the proxy was imported from DEV to QA and it is working in QA client 050. There is something i need to set up, specific to client 100, and i am missing it. I looked in SOAMANAGER, and i didnt see anything even set up there for client 050, so i did set up anything for client 100.
Any help would be appreciated.

I tried adding the web reference in a console app and works fine. In the plugins this can't be done, because the plugins are deploy in database.
I tried another basic test using ChannelFactory. Only want to retrieve some entity through the external web services:
IPluginExecutionContext context = localContext.PluginExecutionContext;
IOrganizationService service = localContext.OrganizationService;
ITracingService tracer = localContext.TracingService;
try
BasicHttpBinding binding = new BasicHttpBinding();
binding.Name = "BasicHttpBinding_IAxxisWcfServices";
binding.Security.Mode = BasicHttpSecurityMode.None;
binding.Security.Transport.ProxyCredentialType = HttpProxyCredentialType.None;
binding.Security.Transport.ClientCredentialType = HttpClientCredentialType.None;
EndpointAddress endpoint = new EndpointAddress(@"http://*****.svc");
ChannelFactory<IAxxisWcfServices> factory = new ChannelFactory<IAxxisWcfServices>(binding, endpoint);
IAxxisWcfServices channel = factory.CreateChannel();
var entity = channel.FindByEntities(new CRM.Application.Context.Dtos.Asegurado( { CrmGuid = "7C3E96C6-C3BC-E411-80DF-0A736AE14667" }, null, new CRM.Framework.Session() { User = "***", Password = "***" });
catch (Exception ex)
throw new InvalidPluginExecutionException(ex.Message);
That test threw the following exception on the GenericParameterAttributes of channelType of factory object:

Best Practises for Error Handling

Hello
I have a PHP front end application and for now an Oracle database in the backend. User defined errors are returned back to PHP front end using RAISE_APPLICATION_ERROR(-20000,'error msg'), the PHP displays the message to the user. We have a problem where we are now going to provide a French version on the application and are stuck at what we are to do with the error messages.
What is the common practise for this?

Don't reinvent the wheel. Oracle provides built-in error globalization.

Error while calling an external javascript file

Hi,
I have added a javascript file into the public_html folder, i have named it main.js.
I have a html file in which i am referring to the javascript externally , this too is in my public_html folder. But the HTML page does not seem to be able to invoke the javascript.It does not even enter the method.
My code is as follows
html file
<head>
<title>untitled1</title>
<script language="Javascript" src=\"\main.js\" type=\"text/javascript\"></SCRIPT>
</head>
<body>
<form name="test" method="POST" action="test">
<input type="button" value="submit" name="submit" onclick="analyze_page()">
</form>
</body>
</head>
main.js
<script language="Javascript">
function analyze_page(){
alert("testing if it works");
</script>
(2)
Secondly, I also have a servlet in a package com.oracle.prod, what is the path I should give in the servlet <SCRIPT> tag so that the javascript is accessible while the page gets rendered

Hi Kart,
Try to do:
<script language="Javascript" src="<c:out value="${pageContext.request.contextPath}"/>main.js" type="text/javascript"></SCRIPT>
In that way you can access the context path of your application.
So, another thing that I noted is \" it's unecessary if you are editing directly a jsp/html file.

Best error handling for visa calls?

We are using some handlers we've devloped for power supply handling (over GPIB). The power supplies are SCPI and use SCPI/GPIB commands. The handlers use the NI visa api's Read() and Write() functions to send the commands. They work fine, for the most part, and we've been using them for a number of years.
However, we're hearing reports that there may have been a few times that commands were not executed on the power supply and our handler did not report back any error.
So, I'm trying to update these handlers to add a little error checking to make them more robust and hopefully we'll catch this error if it happens again.
For error handling, I've come up with 3 solutions and tried all 3. I find some benefits and drawbacks with each and hoped I could get your opinions about error handling as I'm not overly familiar with some of the methods.
Method 1:
Set the Event Status Enable register to catch all events (or all that I care about).
Read status byte (STB?) after each command and check the event bit and then event status bit if event bit set.
Drawback1: I have one power supply that does not implement this correctly and a second type that appears to not be working correctly either.
Drawback2: Errors are generic. I'll know if I got, for example, a DDE (Device Dependant Error), but I won't know more detail than that.
Method 2:
After each command sent, read the error queue with the System:Error? query.
Drawback: It seems I get a lot of messages back in this method that aren't real errors. It's very "noisy" and I have no way to distinguish real errors from "noise" messages like "query interrupted" and such.
Method 3:
Check the return code of the Visa Read() and Write() commands. At first I didn't think this was very robust, but after seeing the list of errors here, I'm beginning to think that these might be more robust and detailed than Method 1. However, I'm not sure.
So is method 3 as robust as it looks, or is there a combination/comprimise I can make, or another method I did not mention which is best to trap errors from Visa Reads/Writes to these GPIB power supplies? Keep in mind that the handlers work for a number of different power supplies and its likely that some things may be implemented differently between supplies....so its best to stick with somethind standard that will work on all power supplies.

Hi KingTermite,
I hope you will got answer of the question and may be implemeted something .It was really a nice discussion .I am also facing the same issue where I am communicating with different instrument using GPIB communication and RS 232 too.
Can you share and discuss about the implementation of your initiative.

Transaction Handling via Multiple Stored Procedure Calls

Hello,
we have the requirement that we call severall stored procedures in a sequence. The problem now is to have one explicit transaction which is only commited in case all calls have been succesful. In case there is an error during one of the calls all already executed stored procedures should be rolled back.
One idea would be to define transactional behavior in BPM within a block but I have some doubts whether this works as I have found the following warning in the SAP XI help section:
"The transaction control mechanism for integration processes is not a central transaction manager for an entire system landscape. The transaction control mechanism cannot roll back any processing steps outside the Integration Server"
Do you have any advice on this issue?
Thanks a lot!

The best solution would be to call the root SP from XI adaptor and handle the transaction commit logic in side this root SP. That way even BPM will not be in picture.
BPM can not handle transaction roll back on external systems.

External Table which can handle appending multiple csv files dynamic

I need an external table which can handle appending multiple csv files' values.
But the problem I am having is : the number of csv files are not fixed.
I can have between 2 to 6-7 files with the suffix as current_date. Lets say it will be like my_file1_aug_08_1.csv, my_file1_aug_08_2.csv, my_file1_aug_08_3.csv etc. and so on.
I can do it by following as hardcoding if I know the number of files, but unfortunately the number is not fixed and need to something dynamically to inject with a wildcard search of file pattern.
CREATE TABLE my_et_tbl

I have configured RFC connections in the administrative tools. Still it is not working.
What should be the reason behind this?
Thanks,

Hi Guys,
i have the same issue when calling a external service ...
I'm calling a web service located on my server, and i get the same error ...
I have a error while the method "loadbycustomkeys" is trying to get data from the web service.
in the error trace i find the same error id : nullSourceOrTargetForMapping which occurs in the readMappingRule method.
have you found a solution for your issue please ? let me know !

Rpc error calling an external procedure

I'm having a problem calling an external procedure running on Linux. The setup works using NT and a DLL, but when the function has been converted to a .so library, I get get
ORA-28575: unable to open RPC connection to external procedure agent
Now this is probaly due to my listener config since when starting the listener I get an IPC error:

I'm using Oracle 8.0.5 and RedHat 6.0. The name of machine is elvis and the sid name is elvis as well. Any bright ideas are more than welcome
Ben

your listener.ora file has problem!
it should look similiar to:
LISTENER =
(DESCRIPTION_LIST =
(DESCRIPTION =
(ADDRESS_LIST =
(ADDRESS = (PROTOCOL = TCP)(HOST = elvis)(PORT = 1521))
(ADDRESS_LIST =
(ADDRESS = (PROTOCOL = IPC)(KEY = EXTPROC))
SID_LIST_LISTENER =
(SID_LIST =
(SID_DESC =
(SID_NAME = PLSExtProc)
(ORACLE_HOME = <substitute with your oracle home>)
(PROGRAM = extproc)
(SID_DESC =
(GLOBAL_DBNAME = elvis)
(ORACLE_HOME = <substitute_with_your_oralce_home>)
(SID_NAME = elvis)
please verify with net8 admin guide. you also need to set up tnsnames.ora correctly at client side.

I am able to hit external ws from soap ui and getting response but while calling from soa suite getting this error.
Any clues?
Thanks
Vibhor

WS Binding: exception durign SOAP invocation: java.util.NoSuchElementException
Looks like the error is in the data sent to or expected from the service in your composite. Check that audit logs and composite flow to make sure your soap message when using soapui matches what you are working with in soa suite.

Error while calling external webservice.

Hi
I am trying to call an external web service but getting following error.
exception on JaxRpc invoke: HTTP transport error: javax.xml.soap.SOAPException: java.security.PrivilegedActionException: javax.xml.soap.SOAPException: Bad response: 503 Service Unavailable
I am using SOA Suite 10.1.3.4 and trying to call this service from BPEL.
This service is not a secured service and we are able to call it using SoapUI tool and by simple java code also.
We are able to ping this service from SOA server too.
What might be the issue?Any settings required at soa server?
Any thoughts
Thanks
Vibhor

Hi
Finally I got the issue fixed.
Our soa server is using a proxy for outbound interactions, so just added external service Ip in exception and its working now.
Thanks
Vibhor

Error Handling in File to Multiple IDOC Scenario?

Hello Experts,
My scenario is file with Multiple records and I want to send it to SAP system.If there will be 10 Records in my file I need to create 10 IDOC in Target system.
I can use below of the two options.
1) File to Multiple Idoc (1.N Mapping)
2) Using BPM
3)Directly place the file in SAP application server and process it via ABAP Program.
However I am not clear in which option error handling will be more effective.Please suggest.
Basically I want to handle If out of 10 records 9 are correct and 1 record is not correct then I should be able to report within PI without affecting 9 correct records.Is it possible 9 records will be sent to SAP system and PI will only show error for 1 incorrect record.
Also I will be doing this scenrio for transaction data with huge size (1 Million Records).Which approach will be more effective in this case.
Thanks,
Pushkar

Hi Patel,
I want to handle If out of 10 records 9 are correct and 1 record is not correct then I should be able to report within PI without affecting 9 correct records.Is it possible 9 records will be sent to SAP system and PI will only show error for 1 incorrect record.
when working on graphical mapping, the target structure is created when there are no errors in all records of source structure.
suppose if we have validation error in 9th and 10th record, then we can not process the first eight records and inturn we can not store the two error records in XI for further.
i suggest you the third option, you can directly place the file in SAP application server and process it via ABAP Program.
this is far better because you can do more customizations as you have to deal with millions of records.

Pradeep A.
