Camel file movement from one folder to another sometimes giving exception saying "Cannot rename file"

[Pallavi G S <ra...@gmail.com>]

Below is the configured route :

<camel:endpoint id="srcFolder"
			uri="file://SRC?move=.Success&amp;moveFailed=.Error" />

<camel:endpoint id="destFolder"
			uri="file://DEST?move=.Success&amp;moveFailed=.Error" />

<camel:route>
	<camel:from uri="srcFolder" />
	<camel:threads maxPoolSize="12" threadName="tid" id="tid" poolSize="10">
		<camel:process ref="myProcessor" />
		<camel:to ref="destFolder" />
	</camel:threads>
</camel:route>

<bean id="myProcessor" class="com.abc.module.MyProcessor" />


Suppose there are 1000 files in the folder SRC,after the route is
executed,in the DEST folder i can see all the 1000 files.
But once the file is picked and processed,the files are moved to .Success.
After processing there will be few files missing in .Success/.Error folder.
There will be only 990 files moved to .Success but in DEST folder there will
be 1000 files.

Getting below exception for the missing files in .Success folder:

Hi,
I am not sure what are you trying to do but your destination Folder should
not contain move and move failed option .

At the same time change move to premove to avoid conflict.

/<camel:endpoint id="srcFolder" 
                       
uri="file://SRC?premove=.Success&amp;moveFailed=.Error" />
<camel:endpoint id="destFolder" 
                        uri="file://DEST" />
/
