Subject Unable to delete file after processing on Windows
Date Tue, 23 Feb 2010 01:58:53 GMT

Hi,

I'm having a problem where Camel is unable to delete a file after processing
it in a route.
Problem occurs only on WinXP; on Linux it works fine.
My route looks something like this:

from( "file://foo?delete=true" ).process( proc1 ).recipientList( header(
"xyz" ).tokenize( "," ) );

Here, proc1.process() adds a header named "xyz" which is a comma separated
list of ActiveMQ URIs.

The route kicks in, processes the message but the last step of deleting the
input file fails with the
stack trace shown below. Changing the file disposition to rename makes no
difference and it fails
the same way. From the stack trace, it looks like a thread is trying to do
the delete while another
thread still has the file locked.

Any help is much appreciated, thanks.
