[file2/ftp2]Source file not deleted after using a combination of
file2 component and ftp2 component with templates
Hello,
I'm having trouble when working with producerTemplate and consumerTemplate
in the following scenary:
1. I read a file from a local directory with a consumerTemplate. The only
options I'm using are: {fileName, charset, intialDelay, delay}
2. I copy that file to an ftp directory using a producerTemplate.
At the end of the process, the source file (the one that I read from a local
directory) is not deleted. If in the second step I use a file component
instead of an ftp component it works as expected.
When the file is not deleted, I have this trace in the console:
2012-07-06 13:35:40,815 WARN

I attach a simple test that reproduces what is happening to me (the only
thing that the test needs to work is to change the ftp endpoint
configuration apart from editing the package of the class).
I have been thinking that using a bean that uses the
org.apache.camel.util.FileUtil to explicity delete the file would be an
option, but since camel It's supposed to do that and in the trace I have
seen that camel already uses that library I don´t know which is the better
way to do this.
Thanks in advance.

Thanks for your quick response Claus.
I have checked the test I uploaded, it´s true that there is a
FileOutputStream but it has its "close()" method. In addition for
double-checking I removed all references to any *Stream to check that even
then the test fails.
Strangely this only happens when the file I read is copied to an ftp dir, if
I use a file endpoint in this step, the behaviour is the expected.
Thank you.

Hi
When using files on windows, make sure that if you use any custom code
that read the file using a stream ,such af FileInputStream, etc. you
must close the stream.
On windows the file cannot be moved/deleted if that occurs. So double
check your own code first.
