The problem statement is to do multiple things parallely and aggregate the response and store it in a file.
link to the mule flow image as in studio:
image
In this flow, what I was trying to do was to set two constant strings in two branches of scatter and gather and aggregate and store in file. I tried overwriting the payload with a "set payload" with "my response". I am expecting "my response" as the content of the file. But instead the file content is:
¨Ìsr)java.util.concurrent.CopyOnWriteArrayListx]ü’F´ê√xpwtmsg 1tmsg 2x
I did debug and the payload at File endpoint was "my response". How and why is the collection getting written into file.
Can anyone help me to get it working.
Following is the xml:
<flow name="mule-assignFlow21123">
<quartz:inbound-endpoint jobName="dummyflow" repeatInterval="10000" responseTimeout="10000" doc:name="Quartz">
<quartz:event-generator-job/>
</quartz:inbound-endpoint>
<scatter-gather doc:name="Scatter-Gather1" >
<threading-profile maxThreadsActive="1" poolExhaustedAction="RUN"/>
<processor-chain>
<set-payload value="msg 1" doc:name="Set Payload"/>
<logger level="INFO" doc:name="Logger"/>
</processor-chain>
<processor-chain>
<set-payload value="msg 2" doc:name="Set Payload"/>
<logger level="INFO" doc:name="Logger"/>
</processor-chain>
</scatter-gather>
<set-payload value="my response" doc:name="Set Payload"/>
<file:outbound-endpoint path="/Users/premkumar/Desktop" outputPattern="Results.txt" responseTimeout="10000" mimeType="text/plain" doc:name="Save 2 File"/>
</flow>
The flow will automatically determine the processingStrategy from the in-flight event which will be async because of the quartz endpoint, so the file endpoint will fire async also.
Instead explicitly set the flow's processingStrategy to synchronous:
<flow name="mule-assignFlow21123" processingStrategy="synchronous">
<quartz:inbound-endpoint jobName="dummyflow" repeatInterval="10000" responseTimeout="10000" doc:name="Quartz">
<quartz:event-generator-job/>
</quartz:inbound-endpoint>
<scatter-gather doc:name="Scatter-Gather1" >
<threading-profile maxThreadsActive="1" poolExhaustedAction="RUN"/>
<processor-chain>
<set-payload value="msg 1" doc:name="Set Payload"/>
<logger level="INFO" doc:name="Logger"/>
</processor-chain>
<processor-chain>
<set-payload value="msg 2" doc:name="Set Payload"/>
<logger level="INFO" doc:name="Logger"/>
</processor-chain>
</scatter-gather>
<set-payload value="my response" doc:name="Set Payload"/>
<file:outbound-endpoint path="/Users/premkumar/Desktop" outputPattern="Results.txt" responseTimeout="10000" mimeType="text/plain" doc:name="Save 2 File"/>
I have following Code for my Mule FLOW and seems like something is wrong with my code which is not allowing to invoke Catch Exception Strategy, What are the corrections required here ?

I am trying to put invalid WEBSERVICE URL here which is causing this error and i want to catch those kind of errors and send out emails if service is down or configuration is wrong and not able to process the files :
What i need to change here in my code which will allow me to receive email notification about this error ? Can you please advice me what's wrong with Exception Strategy here?

Either one of the following:
Add "|| exception.causedBy(java.net.UnknownHostException)" to your first exception strategy to catch only unknown hosts exception.
Change your second catch exception strategy into exception.causeMatches('java.net.*') to catch all network exceptions (notice the quotes).
Change your second catch exception strategy into exception.causeMatches('java.*') to catch all java exceptions (notice the quotes).
Hi I am working with Mule Any Point Studio. I want to define one queue name and from that queue i want to read the data using AMQP.
Its not polling the data from the Queue which i mentioned.
My Mule Flow:
<amqp:connector name="amqpConnector" doc:name="AMQP Connector" host="localhost" port="5672" username="admin" password="admin" validateConnections="true" ></amqp:connector>
<flow name="mule-ampq" doc:name="mule-ampq">

<logger message="#[message.payload]" level="INFO" doc:name="Logger"/>

In Mule flow how can I re-use choice-exception-stretegy across several flows?
I tried the following, but it throws error when I run mule application.
<mule ....>
<choice-exception-strategy doc:name="My_exception_strategy">
<catch-exception-strategy when="exception.causedBy(java.net.SocketTimeoutException)" doc:name="Strategy1">
<logger message="message 1" level="INFO" doc:name="Logger"/>
</catch-exception-strategy>
<catch-exception-strategy when="exception.causedBy(java.lang.Throwable)" doc:name="Strategy2">
<logger message="message 2" level="INFO" doc:name="Logger"/>
</catch-exception-strategy>
</choice-exception-strategy>
<flow name="Test1" doc:name="Test1" processingStrategy="synchronous">
<logger message="message 3" level="INFO" doc:name="Logger"/>
<outbound-endpoint ref="myendpoint" doc:name="MyEndPoint"/>
<exception-strategy ref="My_exception_strategy" doc:name="Reference Exception Strategy"/>
<set-variable variableName="somevalue" value="#[something]" doc:name="statusCode"/>
</flow>
</mule>
There are two issues with the config you have posted.
There is a "set-variable" after the exception strategy. No other processors are expected after the "exception-strategy".
The exception strategy is not named. The attribute "name" is missing for the exception strategy.
Try the following flow .
<mule ....>
<choice-exception-strategy name="my_exception_strategy" doc:name="My_exception_strategy">
<catch-exception-strategy when="exception.causedBy(java.net.SocketTimeoutException)" doc:name="Strategy1">
<logger message="message 1" level="INFO" doc:name="Logger"/>
</catch-exception-strategy>
<catch-exception-strategy when="exception.causedBy(java.lang.Throwable)" doc:name="Strategy2">
<logger message="message 2" level="INFO" doc:name="Logger"/>
</catch-exception-strategy>
</choice-exception-strategy>
<flow name="Test1" doc:name="Test1" processingStrategy="synchronous">
<logger message="message 3" level="INFO" doc:name="Logger"/>
<outbound-endpoint ref="myendpoint" doc:name="MyEndPoint"/>
<exception-strategy ref="my_exception_strategy" doc:name="Reference Exception Strategy"/>
</flow>
</mule>
Hope this helps.
I am using the following fork and join pattern in my flow.Parallel processing works just fine. However, I have issues with exception handling. I want to implement an exception strategy for the processing happening on VM response inbound endpoint of the router. However, it seems my nothing happens when I am trying to write to response, from within the catch exception strategy block. When there is an exception, I am able to see the log statement from the catch block, but the response on browser just hangs.
Please suggest.
