Issue in Proxy service Error Handler.

Hi,
Is it possible to reset or clear all variables used in a proxy service in error handler.

Hi,
You cannot delete all the variables at once.
Please refer to the below link.

Issue in Proxy service call

Hi,
The proxy service is getting called twice for invalid input.Its working fine for valid input.The logic i used is,checking the input file and calling an raise error action in case of validation fails.I gave retry count to 0.Is it possible to stop the whole proxy in error handler?

Hi,
Got your issue now.
There is no problem with your service configuration. Changes required at server level. Let me explain this
Instantiation is happening because of transactional & retries configuration, but when you are using reply action in error handler you are actually completing the transaction by sending reply. The error I suspect is to be effect of redelivery-limit=1.
eg in xbusResources-jms.xml in your domain config
<queue name="wlsb.internal.transport.task.queue.file">
<sub-deployment-name>wlsbJMSServer</sub-deployment-name>
<delivery-failure-params>
<redelivery-limit>1</redelivery-limit>
</delivery-failure-params>
<jndi-name>wlsb.internal.transport.task.queue.file</jndi-name>
</queue>
Follow the below steps
On Weblogic Admin Console go to
Services > Messaging > JMS Modules
See if you can find a module called "jmsResources"
In jmsResources configuration check for ... wlsb.internal.transport.task.queue.file
There go to Delivery Failure tab. The Redelivery Limit must be 1 there.
Change it to 0.

Exception caught if error is raised in Service Error Handler

Can any one help me on this? Im not able to understand the funda for the behaviour?
Proxy Service A calls proxy service B using Publish action. In proxyservice B - service error handler, Im raising an error with customised message. Proxy service B routes to another proxy service C which routes to Business service.
If my business service gives me timed out , error is handled at Proxy service C error handler , and again Proxy Service B error handler is invoked. Here my code stops where Im raising the error.
When I raise error in Service Handler where it is being caught?
Thank you in advance.
Regards,
Vyshnavi

Hi Vyshnavi,
There are four levels where you may define an Error Handler and it will catch errors related to this level only. If it could not handle any error reached to it, it will propagate the error to the higher level error handler. All errors which can not be handled at lower levels, System Error Handler, handles those.

How to take control back from service error handler in osb

I am using osb to send data to multiple services at the same time.since x query is a procedural language if any single operation fails the flow goes to service error handler which calls a BPEL webservice and logs the error in a database but the control doesnt comes back to my code I have tried everything including RESUME,REPLY operations but all in vain similarly i cannot use service callout call to my business service because its not allowing to select my BPEL wsdl operation

If your statement "the control doesnt comes back to my code" means you expect that your xquery will continue in processing than your expectations are just too high. :-)
Resume action is supposed to resume the next action in the message flow. It means the action that follows the action which caused an error.

ALSB Proxy Service error calling Business service

I have an external webservice on Weblogic 8.1 SP5, and I configured Business Service in ALSB 2.6, that is able to invoke the external webservice. But When I create Proxy Service based on the existing Business service and try to invoke the proxy service I get "no SOAP Action Header" error in WebLogic 8.1 SP5 External webservice.

Also I get

Is it a known issue ?

The back end service basically complains the SOAPAction http header was not included in the request. Typically this header is added automatically by ALSB if the proxy is of type SOAP and the wsdl contain the SOAPAction value for the operation invoked.
Alternatively you can force the SOAPAction header to be set to the correct value by adding a transport header action in the request part of the routing node.

Web Service Error handling in JDev 11g

Hi,
I followed the steps on this tutorial: "Use JDeveloper 11g to Create a Data Control From a Web Service"
http://www.oracle.com/technology/obe/obe11jdev/11/wsdc/wsdc.htm
In this tutorial, under the section "Running the Page", you will see the image where an error message is displayed - "SoapException - Server was unable to process your request...."
I also get this error when I follow the tutorial's steps. If I repeatedly press the GetWeatherByZipCode commandButton, the message goes away and I get the data in the table as expected.
What I'd like to do is not show the end user this error, but instead eat the error and retry the request a few times. If after a few tries, I still get the error, then I can show the end user a nicer message.
How do I do this? Any documentation you can point me too would be appreciated. I'm new to the 'bindings' layer. I usually use JavaBeans/managed beans.
I'm using JDeveloper 11g (Main build from Oct 15th)
Thanks,
Jeanne

I've read about binding to #{adfFacesContext.initialRender} to not call the web service on initial render which is what you are probably talking about.
However, I get this error even after the first time I've displayed the page. I've heard that you cannot rely on web services always coming back to you with data ((e.g., like Twitter's data - that was the example I was given at a recent Google Tech Talk) . I need to handle the case where I get an error from the web service and I retry calling the web service behind the scenes so the end user is unaware. This is what I want to do. I can retry a few times, then give up, then pop up a nice error.
Thanks,
Jeanne

Web service error handling (SOAP 1023 SRT: ICM_HTTP_CONNECTION_FAILED)

Hi there,
When consuimng our web service, sometimes we get the error "SOAP 1023 SRT: Processing error when receiving the response: ICM_HTTP_CONNECTION_FAILED" and this happens when we can't connect to the other system. The requirement is to automatically resend the transaction after +/- 10 seconds. Is there somewhere on the web service settings that will enable us to achieve this without having a background job running every minute?
Thanks.

Hello,
 
The first thing you should do is to check that your application server can reach the service your are trying to call. I suggest to try a:
 
telnet <remote_service_url> <remote_service_port>
 
from the command line of your server.
 
You should get a blank screen if your server reaches the remote server and something like connecting to <remote_service_url> if you don't.
 
Yours,

Handling Transport Errors in OSB Proxy Services

Hi,
I have a requirement of storing and handling Transport level Security Errors in my proxy services . In fact, my proxy services are secured with HTTP Basic Authentication and i am not able to catch authentication errors. I added a Service Error Handler to my proxy service but unfortunatly it doesn't handle these errors.
Does anyone know how can we catch these errors in OSB, and if it is possible to execute activities like alerts, reports, logging in these cases.
I read in some blogs that Error handlers are nested like this : Route Node -> Proxy Service -> System Error Handler
so maybe it would be good to customize the System Error Handler Behavior. I don't know if this is possible.
Any help will be appreciated.
Best regards
Farouk

Transport level authentication is done at transport layer even before the actual proxy service gets initiated. So you wont be able to catch authentication errors in the proxy service (and do alerting/logging/reporting etc). You can probably try enabling debug logging for HTTP protocol and see if you can capture these errors in the Access.log of the servers.

Osb - bind error handler to proxy service

Hi!
I have got a proxy service which polls a POP3 server to download emails and process them.
My question: How could I bind an error handler to proxy service for noticing when the POP3 server is not available?
So I would like to put an alert when the OSB looses the connection to email server. I tried to put an error handler to top component on message flow but it doesn't work...
Could anyone help me?
Thanks!
Viktor

For poller transports (email/File/FTP etc) it is not possible to catch errors of transport layer, in your service error handler. Re: OSB - Error Handler in FTP Transport for TransportException

OSB - Error handling, report via service callout?

I'd like to use Report Action on any error happened in my services. I'd also like to keep only one Report Action to be able to change its configuration later easily if needed.
As it seems currently, if I add the Report Action to the Error Handler of the service directly, it logs the error code/reason/etc correctly, but if I move the Report Action to a separate service and add a service callout to the Error Handler instead of calling the Report Action directly, I lose the error information (I get the report message but error code/reason/details will be all NULL in the database).
Am I doing something wrong here? Is that a limitation of the product? Is there any solution to keep the report actions centralized in this case?
Thanks..

hi guys,
thanks for all the suggestions though it's still not working here. Hopefully clarifying the situation:
a) service -- error handler -- report error
b) service -- error handler -- service callout -- report error
a) works, b) does not.
The syndromes for not working is that the reported message has error code, reason and detail all empty (NULL if I look directly in the database). I suspect the problem is with my service callout in scenario b).
The service callout originally was made using the following parameters:
Request document variable: body
Response document variable: response
SOAP request header: header
SOAP response header: rheader
Reading your suggestions I tried to set the request document variable from 'body' to 'fault', but it did not help either: I get the report message but still no error information in the message.
How exactly should this service callout look like to properly transfer the error details to the called pipeline?

Error Handling in OSB

Hi,
In OSB how to catch all different errors and send them to specific
For ex:
1.if i get a "file not found" error, i need to send an email notification
2.if i get an arithmetic error , i need to send it to database
like any other errors...
Can we handle all those errors in a single error handler and send them to specific targets
let me know any questions

basically what is did is create a generic proxy service which will contain all the logic to handle your faults.
so in your case you could create a soap or xml proxy service (let's name it ErrorHospital).
the input of this proxy service needs to contain all the data you need to decide what to do with a certain error.
for now let's make the interface something like
<errorMetadata>
<error>{$fault}</error>
<payload>{$body}</payload>
</errorMetadata>you could just add me metadata from the proces which is failing ofcourse, it's up to you to decide what data you need.
now in for example the EmployeeService something fails.
In the EmployeeService you add a service error handler, and for the start in this service error handler we will only do a publish to our new 'ErrorHospital'.
Create the <errorMetadata> element in here and do the publish.
At this stage we have all the metadata available in our ErrorHospital proxy service, so we can execute all the logic needed for any specifica error.
In the ErrorHospital proxyservice you could add something like
if $body/errorMetadata/error/faultCode = 'MAIL-001' then send mail (by use of a mail transport business service (this expression won't work, but just to show what's possible)
in my blog i used a ErrorRepository in which i configure what actions to execute based on the errorCode
so you could add MAIL-001 in this repository and define something like
log_YN = Y
mail_YN = Y
report_YN =N
the generic logic in your errorHospital proxy service will contain a list of
if - then - else combinations to decide if it should mail, or if it should log or if it should report
and this will work on every errorCode you define in the ErrorRepository.
It's a solution we use at my current customer too and works pretty nice, and the administrators can update the ErrorRepository file from the console on production if they decide on a certain moment that they need logging on some errorCode for example
hope it's a bit clear like this

Reporting Action in Error handler

We have a requirement to use Reporting action in the Service Error Handler to capture some details for the reports. We are using the JMS Messaging Proxy and in that transport options, we are using "Transaction" as Enabled to retry the failed messages.
Now when ever there the flow fails and is goes to the service error handler and there are no reports getting generated in the "Opeations->Messaging Reports". But when the "Transaction" option in the Transport option is disabled in the Proxy, we are getting the reports.
Is there any way to get the Reports generated with the "Transaction" option enabled ?

Then your reporting provider is handled within the same XA transaction as your proxy. Either both commit or both rollback. If you want to report error than you can still use XA transaction for your proxy, but you can't use it for your reporting provider.

Conditional Error handling

This is my use case
My proxy will call a business service which will call the DB and execute a SP . The SP will return 1-* rows. Assume the rows have 10 columns. The 10th column is the status. even if there is some functional error the SP will return 1 row with the 10th columns populated.
This is the possible values of the 10th column (Status)
OK, E1, E2,E3, D
OK - Output is ok . I will transform the output and call another BS to insert into another DB
D- Discard . just skip the message flow . no need to insert into the DB.
E1 ,E2- Retry 2 more time with an interval of 1 min. but I need to log the original body
E3 - Retry 2 more time with an interval of 1 min. but I do not need to log.
I have created 2 proxies and 2 BS.
P1 -> P2 - > BS1. For the service callout of P2 from P1 I have set the routing option for Retrycount = 2 , retyinterval=60 secs.
P2 will call BS1 and check the output Row1 and column 10 index and based on that it will do the following. For E1,E2,E3 it will raise Error with Error code E0001, E0002, E0003 . For D and OK it changes the body accordingly.
In P1, I put and if condition to validate the return of P2. For OK I call BS2, For D I call the Skip action
For E1,E2 and E3 they get trapped in the Stage error of P1.
Everything works fine till here, but how do I identify in stage1 error handler if the error is caused by E0001 or E0002 or E0003 so I can log the original body and log the cause of the error is E0001 or E0002 ???

This is the $fault output
<con:fault xmlns:con="http://www.bea.com/wli/sb/context">

 </con:location>
 </con:fault>
It does not give me the Error code which is raised in my service callout proxy.
Let me try and simply my scenario.
Proxy 1 calls Proxy2 by service callout . Proxy 2 based on certain error condition will raise error code like E0001 , E0002 etc..
In Proxy 1 Error handler, I want to find out if the error is caused because of E0001 or E0002. How can I achieve this ?. I have posted Proxy 1 $fault variable which outputs a generic error message.

Query related to error handling

hi All,
In my proxy flow i have stage level error handler which is configured to an alert pointing to an JMS error queue. When i added service level error handler with same alert.
I am getting duplication of the same error message by stage and service error handler.
For every error i am receiving 2 error messages at the error queue.
Is there any option in ALSB which allows me stop the duplication.

Pls check the following script --
