Default error channel is not handinly the exception which thrown by ServiceActivator

[samba.gaddam]

Hi All,

Could you please help me handle the exception in integration flow, which thrown by service activator class.

I have one service activator class in that i am doing DB operations. if any error it throw exception.

default "errorChannel" is not handling those exceptions , could you please help me to handle those exception in flow.

You need to add an error-channel attribute to the originating endpoint (start of the flow); it will catch the exception and send an ErrorMessage to the error-channel; the ErrorMessage has a payload of type MessagingException which has two properties (failedMessage - the message, and cause - the exception thrown by the service).

Hi Gary,

Here our flow is like
<int-jms:outbound-channel-adapter ---> cic (custom) header enricher --> service activator --- here I don't have a option to add error-channel attribute.

I assume you mean INBOUND channel adapter - that's where the error-channel goes.

Hi Gary,

I am able to get the message in errorChannel, actually I am loosing my payload ,I am not able to get the actual payload to update the status.
I am getting like
Payload=org.springframework.integration.MessageHan dlingException: org.springframework.dao.DuplicateKeyException: SqlMapClient operation; SQL [];

I tried :
<int:transformer ... expression="payload.failedMessage" .../> too, I am getting

org.springframework.expression.spel.SpelEvaluation Exception: EL1008Epos 8): Field or property 'failedMessage' cannot be found on object of type 'java.lang.String'

Could you please help on this.

Please provide your actual configuration, together with a DEBUG log (for org.springframework.integration), starting with 'preSend on errorChannel'.

Another couple of things you can try:

in your error handling route, set up a logging outbound adapter instead of the transformer have it dump the message for a quick debug.

<int:logging-channel-adapter id="TEMP_ERROR_LOGGING" channel="errorChannel" level="ERROR" log-full-message="true"/>

or you can try hooking up a wiretap to your error channel to log the data going through your error channel (assuming your channel name is "errorChannel")

<int:wire-tap pattern="errorChannel" channel="wiretapChannel"/>
<int:logging-channel-adapter id="WIRETAP_LOGGING" channel="wiretapChannel" level="ERROR" log-full-message="true" />

Then you can see if you're getting the expected message format.

Hi Gary,

please find the below details.

<!-- JMS config -->

<int-jms:message-driven-channel-adapter
id="messageDrivenChannelAdapter" channel="header.enricher"
container="LbQueueContainer" error-channel="common.errorChannel" />



<!-- Integration config -->

<int:chain input-channel="jdbc.data.in" output-channel="select.data.out">
<int:header-enricher>
<!-- <int:error-channel ref="errorChannel"/> -->
<int:header name="p2p.so.ace2gems.notif.original.payload"
expression="payload" />
</int:header-enricher>

<int:chain input-channel="select.data.out" output-channel="update.status.in" >
<int:service-activator ref="refService" method="insertAceData" />
</int:chain>


<!-- Handling Error Notification updates -->
<int:chain id="p2p.so.ace2gems.updateAce.notification.error"
input-channel="errorChannel" output-channel="c.prepare.to.update.notification">
<int:transformer expression="headers.get('payload')"/>
<int:header-enricher>
<int:header name="${status.processflag}"
value="${status.error.value}" />
<int:header name="${status.message}" value="${status.message.value}" />
</int:header-enricher>
</int:chain>

preSend on channel 'errorChannel', message: [Payload=org.springframework.integration.MessageHan dlingException: org.springframework.dao.DuplicateKeyException: SqlMapClient operation; SQL [];

Please use [ code ] ... [ /code ] tags when posting code and config (no spaces in brackets).

This is incomplete - your jms adapter sends errors to "common.errorChannel" - the above flow (and partial log) shows "errorChannel" and I don't see the transformer you were asking me about (<int:transformer ... expression="payload.failedMessage" .../>).

Please provide the full information I asked for, and, as I said, I need the log STARTING with PreSend and INCLUDING the "org.springframework.expression.spel.SpelEvaluatio n Exception: EL1008Epos 8): Field or property 'failedMessage' cannot be found on object of type 'java.lang.String'" message.
