Servlet reloading problem

[Roy Truelove <ro...@binghamton.edu>]

I teach a class where I've got 50 students that have to write guestbooks
with servlets, with a context for each student.. the perfect environment for
testing servlet reloading.  For the most part reloading has worked
wonderfully except in one case.. the students use file I/O to store the
guestbook.  If they use one file, it works fine, but if they change the name
of the file, reupload it, the servlet without fail will be reading / writing
the *old* file.  Once I restart the server, this is no longer a problem.

Now since they are students, they might not be closing the file, which could
have something to do with problem.  Once I get their source code I could
tell you for sure.

If this is already in the bug database, I apologize, but I've still to
figure out how to Bugzilla. :)

Just something to chew on,
Roy

Hi!

Just my wild guess:
You student is using another class to manipulate the file and Tomcat can only
reload the updated servlet class but not the classes used by the servlet.
