File component : file don't move
Hello.
sometimes, but not each time, I got Exceptions :
org.apache.camel.component.file.FileComponent@37165f] ERROR
org.apache.camel.component.file.FileConsumer - Can not rename file from:
C:\Temp\amqtest\in\1.txt to: C:\Temp\amqtest\in\.camel\1.txt
java.io.IOException: Can not rename file from: C:\Temp\amqtest\in\1.txt to:
C:\Temp\amqtest\in\.camel\1.txt
at
org.apache.camel.component.file.strategy.RenameFileProcessStrategy.commit(RenameFileProcessStrategy.java:69)
....
and the file 'C:\Temp\amqtest\in\1.txt' didn't move from the directory, and
a file '1.txt.camelLock' didn't delete from the directory, too.
i try to use the route :
<route errorHandlerRef="deadLetterErrorHandlerInfinity">
<from uri="file://C:\Temp\amqtest\in"/>
<to ref="activemq:queue:myq1"/>
</route>
and i use 'JmsTransactionManager'. I say about this, because when i don't
use the 'JmsTransactionManager', it seems that i haven't got this error.
any suggests ?
Thanks.
Evgeny

I found a strange decision of the problem.
There are string messages in my files, and i can append '<convertBodyTo
type="java.lang.String"/>' after <from uri="file.....">. In this case the
route work.

Hi
What version of Camel are you using?
Does this error happens all the time with the JMS TX manager?
Do you mind creating a small sample as a .zip file, then I would like
to take a look.?
The Java IO API in Java is quite terrible when it comes to error
information as the rename operations just return true/false.
So its not possible to know the real cause.
We have to wait for NIO2 in Java 7 for this to be fixed.
Maybe the TX is holding on some stream/object. You can try adding a
little delayer at the end
> <route errorHandlerRef="deadLetterErrorHandlerInfinity">
> <from uri="file://C:\Temp\amqtest\in"/>
> <to ref="activemq:queue:myq1"/>
<delayer>
<delayTime>3000</delayTime>
</expression>
</delayer>
> </route>
See
http://camel.apache.org/delayer.html

Hi
1)
Thanks for sharing this. Without the convert Camel will use the File
handle as body and the JMS producer
will send the JMS as a byte message.
2)
When you do convert body to String you read the content and store it
as plain String on the Exchanage.
Then the JMS producer will just use the String and set a TextMessage.
So there could be a byte stream not being closed, in situation #1.

I found a strange decision of the problem.
There are string messages in my files, and i can append '<convertBodyTo
type="java.lang.String"/>' after <from uri="file.....">. In this case the
route work. and in-files move to backup directory.
