In my principal flow move file from "IN" to "BackUp" but in case occurs exception I want move the file from (I don't know
) to "Error".
How move file from "my cath exception" to "Error" in Mule 3.2?
Use catch exception strategy and use a file outbound endpoint there.
You should be able to send the file to the desired location
<flow>
<inbound-endpoint/><!-- Fill in your details for this component -->
<outbound-endpoint/><!-- Fill in your details for this component -->
<catch-exception-strategy>
<logger message="#[payload]" level="ERROR' />
<outbound-endpoint/><!-- Fill in your details for this component -->
</catch-exception-strategy>
<flow>
On any exception that happens on your flow will be captured in teh exception strategy and the logic or flow you write there will be executed. In this case the paylod is written to a file in the folder that you configure within
</catch-exception-strategy>

I have a logic app in Azure. The trigger is to check when an email arrives into a specific folder in a mailbox. An email may contain 1 or more attachments.
Once triggered, I have an HTTP request that gets sent to a SOAP service. The idea is that I want to check if the filename exists at the SOAP Service.
Its all working perfectly, with the exception, when I reference the filename from the trigger, it includes the file extension. I need to somehow ignore the ".PDF" part of the filename
Below is the XML I post to the SOAP service. Lets say the filename is 12345.pdf, then I need /UniversalEvent/Event/ContextCollection/Context/Value to = "12345" and not "12345.pdf":
<UniversalEvent xmlns="http://www.cargowise.com/Schemas/Universal/2011/11" version="1.1">
<Event>
<DataContext>
<DataTargetCollection>
<DataTarget>
<Type>ForwardingShipment</Type>
</DataTarget>
</DataTargetCollection>
</DataContext>
<EventTime>#{utcNow()}</EventTime>
<EventType>Z77</EventType>
<EventReference>Requesting Shipment ID</EventReference>
<IsEstimate>false</IsEstimate>
<ContextCollection>
<Context>
<Type>HAWBNumber</Type>
<Value>#{items('For_each')?['name']}</Value>
</Context>
</ContextCollection>
</Event>
</UniversalEvent>
do you have any suggestions on what function to use to achieve this?
You can change the expression #{items('For_each')?['name']} in your xml to:
#{substring(items('For_each')?['name'], 0, indexOf(items('For_each')?['name'], '.'))}
My camel route tries to pick up some files from sftp, transfer them to network, and delete them from sftp. If the sftp is unreachable after 3 attempts, I want the route to send an email warning the admin about the problem.
For this reason my sftp address has the following parameters:
maximumReconnectAttempts=2&throwExceptionOnConnectFailed=true&consumer.bridgeErrorHandler=true
In case the network location is not available, i want the route to notify the admin and not delete the files from sftp.
For this reason i have set .handled(false) in onException.
However, when connecting to sftp fails, aggregation also fails and no emails are coming. I have made a minimalist example below:
/configure
onException(Throwable.class)
.retryAttemptedLogLevel(LoggingLevel.WARN)
.redeliveryDelay(1000)
.handled(false)
.log(LoggingLevel.ERROR, LOG, "XXX - Error moving files")
.to(AGGREGATEROUTE)
.end();
from(downloadFrom)
.to(to)
.log(LoggingLevel.INFO, LOG, "XXX - Moving file OK")
.to(AGGREGATEROUTE);
from(AGGREGATEROUTE)
.log(LoggingLevel.INFO, LOG, "XXX - Starting aggregation.")
.aggregate(constant(true), new GroupedExchangeAggregationStrategy())
.completionFromBatchConsumer()
.completionTimeout(10000)
.log(LoggingLevel.INFO, LOG, "XXX - Aggregation completed, sending mail.");
In the logs i see:
16:02| ERROR | CamelLogger.java 156 | XXX - Error moving files
Then the logs for the Exception occurring during connection.
And then this:
16:02| ERROR | FatalFallbackErrorHandler.java 174 | Exception occurred while trying to handle previously thrown exception on exchangeId: ID-LP0641-1552662095664-0-2 using: [Pipeline[[Channel[Log(proefjes.camel_cursus.routebuilders.MoveWithPickupExceptions)[XXX - Error moving files]], Channel[sendTo(direct://aggregate)]]]].
16:02| ERROR | FatalFallbackErrorHandler.java 172 | \--> New exception on exchangeId: ID-LP0641-1552662095664-0-2
org.apache.camel.component.file.GenericFileOperationFailedException: Cannot connect to sftp://user#mycompany.nl:22
at org.apache.camel.component.file.remote.SftpOperations.connect(SftpOperations.java:149)
I do not see "XXX - Starting aggregation." which i would expect to see in the log. Does some kind of error occur befor aggregation? The breakpoint on aggregate(*, *) is never reached.
First, I just want to clarify something. You write "In case the network location is not available, i want the route to notify the admin and not delete the files from sftp", but shouldn't that be obvious anyhow? I mean, if the network location is not available, wouldn't deleting the files from sftp be impossible?
It's a little confusing that your exception handler is also routing .to(AGGREGATEROUTE). Given that you want to email an admin, shouldn't that be in the exception handler, not in the happy path? Why would you and how would you "aggregate" a connection failure?
Finally, and here I think is a real problem with your implementation, you may have misunderstood what handled(false) does. Setting this to false means routing should stop and propagate the exception returned to the caller. I'm not sure what having to the .to(AGGREGATEROUTE) would do in this case, but I'm not surprised it's not being called.
I suggest trying a few things. I don't have your code so I'm not sure which will work best. These are all related and any might work:
Change handled(false) to handled(true).
Replace handled with continued(true).
Use a Dead Letter Channel.
Reference:
Handle and Continue Exceptions
Dead Letter Channel
Since errorhandling is different depending on which endpoint causes the error, i have solved this by having two different versions of onException:
//configure exception on sft end
onException(Throwable.class)
.maximumRedeliveries(2)
.retryAttemptedLogLevel(LoggingLevel.WARN)
.redeliveryDelay(1000)
.onWhen(new hasSFTPErrorPredicate())
// .continued(true) // tries to connect once, mails and continues to aggregation with empty exchange
//.handled(false) // tries to connect twice but does not reach mail
.handled(true) // tries to connect once, does reach mail
// handled not defined: tries to connect twice but does not reach mail
.log(LoggingLevel.INFO, LOG, "XXX - SFTP exception")
.to(MAIL_ROUTE)
.end();
// exception anywhere else
onException(Throwable.class)
.maximumRedeliveries(2)
.retryAttemptedLogLevel(LoggingLevel.WARN)
.redeliveryDelay(1000)
.log(LoggingLevel.ERROR, LOG, "XXX - Error moving file ${file:name}: ${exception}")
.to(AGGREGATEROUTE)
.handled(false)
.end();
Exceptions occuring at the sftp end are handled in the first onException, because there the hasSFTPErrorPredicate returns 'true'. All this predicate does is check if any exception or their cause has "Cannot connect to sftp:" in the message.
No rollback is required in this case because nothing has happened yet.
Any other exception is handled by the second onException.
I am trying to doing ETL job (read,convert, store an excel) .
This route work fine :
from("file:src/data?move=processed&moveFailed=error&idempotent=true")
.bean(ExcelTransformer.class,"process")
.to("jpa:cie.service.receiver.DatiTelefonici?entityType=java.util.ArrayList");
but I need a customization in case of Exception : I need to move file in other folder , then applied :
onException(Throwable.class).maximumRedeliveries(0).to("file:src/data?move=error");
But file component can't move the file because is locket by first file comp instance.
Then I am tryinf to use try/catch but it doesn't work (probably the move operation inside catch is unaware of correct file name ? )
from("file:src/data?noop=true")
.doTry()
.bean(ExcelTransformer.class,"process")
.to("jpa:cie.service.receiver.DatiTelefonici?entityType=java.util.ArrayList")
.to("file:src/data?move=processed")
.doCatch(Throwable.class)
.to("file:src/data?move=error")
.end();
tanks
After many comments my current code looks like :
from("file:src/data?noop=false&delete=true")
.doTry()
.bean(ExcelTransformer.class,"process") .to("jpa:cie.service.receiver.DatiTelefonici?entityType=java.util.ArrayList")
.to("file:src/data/processed")
.doCatch(Throwable.class)
.to("file:src/data/error")
/*
.doFinally()
.to("file:src/data:delete=true")
*/
.end();
It move correctly the file in processed and error folder but the file remain in main folder and is preocessed more ,recursively
If I understood your question well then you need remove the idempotent=true from the parameters, then it should work:
from("file:src/data?move=processed&moveFailed=error")
.bean(ExcelTransformer.class,"process")
.to("jpa:cie.service.receiver.DatiTelefonici?entityType=java.util.ArrayList");
The previous route moves the file to the processed folder if the routing was successful otherwise it moves the file to the error folder (if any exception happens). The filename won't be changed.
Other solution with try-catch
from("file://src/data?delete=true")
.doTry()
.bean(ExcelTransformer.class,"process")
.to("jpa:cie.service.receiver.DatiTelefonici?entityType=java.util.ArrayList")
.to("file://src/data/processed")
.doCatch(Throwable.class)
.to("file://src/data/error")
.end();
I've fairly simple looking route
sftp://hostname:22//incoming/folder/location/?username=username&password=xxxxx
&localWorkDirectory=/tmp&readLock=changed&readLockCheckInterval=2000
&move=processed/$simple{date:now:yyyy}/$simple{date:now:MM}/$simple{date:now:dd}${file:name}
&consumer.delay=450000&stepwise=false&streamDownload=true&disconnect=true
I also have an onException clause
onException(ValidationException.class)
.handled(true)
.logStackTrace(true)
.filter(header("VALIDATION_ERROR").isEqualTo(true))
.choice()
.when(header("CamelFileName").contains("Param1"))
.to(sftp://hostname:22//One/error/folder?password=xxxxxx&username=username)
.when(header("CamelFileName").contains("Param2"))
.to(sftp://hostname:22//Two/error/folder?password=xxxxxx&username=username)
.endChoice();
When I have single file, the route seems to work as expected. When more than one file and exception occurs, I get many different exceptions like
org.apache.camel.component.file.GenericFileOperationFailedException: Cannot list directory: incoming/folder/location
Caused by: java.lang.IndexOutOfBoundsException
I tried using all the attributes mentioned in the route viz. streamDownload, stepwise, readLock, localWorkDirectory et al. However, the error handling while multiple files is not working. I see the first file getting processed. However, it doesn't move to the processed folder once the exception occurs and then incoming/folder/location becomes non listable. I tried using continued(true) as well instead of handled(true)
The problem was with multiple files being handled in the same exchange. On exception, the route was trying to FTP back the error file on the same server. The solution was to split body into multiple exchanges so that each file has its own exchange and process them separately.
from(sftp://hostname:22//incoming/folder/location/?username=username&password=xxxxx
&localWorkDirectory=/tmp&readLock=changed&disconnect=true&stepwise=false
&move=processed/$simple{date:now:yyyy}/$simple{date:now:MM}/$simple{date:now:dd}${file:name}
&consumer.delay=450000).split(body()).processRef("incomingProcessor").end();
I have a Mule application that is writing a file in an outbound endpoint, with the config below:
<file:outbound-endpoint path="${Outbound}" outputPattern="outputFile_#[function:datestamp:yyyyMMddHHmmss].csv" doc:name="Output File"/>
Following this point in the flow I need to display a log message along the lines of "Successfully created file {filename}".
The issue I'm having is that I can't find a way of displaying the name of the file I have just created. I could put: Successfully created file outputFile_#[function:datestamp:yyyyMMddHHmmss].csv, but there is a chance that the datestamp may differ by one second.
Is there a way in Mule that I can display the name of the file I've just written?
UPDATE
Following the response from #til_b, I've achieved this using the following:
<set-variable value="outputFile_#[function:datestamp:yyyyMMddHHmmss].csv" variableName="Filename" doc:name="Variable"/>
<file:outbound-endpoint path="${Outbound}" outputPattern="#[variable:Filename]" doc:name="Output File"/>
<logger level="INFO" message="Successfully created file #[variable:Filename]" doc:name="Logger" />
I dont know about mule, but when i encounter such a problem while programming i store the generated filename in a variable, and then use that variable to actually create the file and display the message.
In Pseudocode:
var filename = #yyyymmddhhMMss.csv
create_file(filename)
log_message(filename + ' successfully created')
