In our setup, we have JSP's that create a temporary file with the

The session timeout (getMaxInactiveInterval) appears to be the
default of 1800 seconds (30 minutes).
We are blasting our servlet container (tomcat and jetty) with JSP
fetches (that don't handle cookies - http_load if you are curious as to
what we are using) and noting that these files stick around till the
servlet container itself quits (the java process goes away). At that
point ALL the files are deleted, and it can take HOURS in some cases to
do so.
Is this expected behavior? We think that these files should be deleted
when the session expires. That seems like the right thing to do.
What you are seeing is what I would expect. The javadoc for
File.deleteOnExit very clearly states that the file is deleted *when the
virtual machine terminates*.
A session is *not* a virtual machine.
I suggest you use a SessionListener object instead; this should be
invoked when the session expires, and you can delete the files then.
