Spring-DM with Jetty on Equinox leaves temporary files around after shutdown

[jschiefer]

Hi Spring wizards,

I have a mysterious issue with leftover temporary files. I am running 2 webapps with Spring DM 1.1.2, Spring Framework 2.5.6, Jetty 6.1.9 on top of Equinox (Ganymede). To debug, I run Equinox with an Eclipse launcher; the deployed software is using a slightly modified version of Apache Commons Daemon to run as a Windows Service. This all works very well together.

However, I have one mysterious problem. When I shut down Equinox ("close" from the console in debug, through the service hooks on production systems), a copy of each of the webapps gets left behind in the appropriate temporary directory (%WINDIR/Temp for the service, or Local Settings/Temp in my user directory for debugging). The filenames look something like this:
jetty-server8039181279835132267.osgi

The tail end of my log file says:

Has anybody seen this before? I don't really know where to even start looking (so far I have considered the WebExtender, well, "magic").

Thank you for any insights,

Those are unpacked war bundles. similar to work directory in tomcat.
I had similar problem, only such temp jetty directories were placed in {current user} /temp. You have to set -Djava.io.tmpdir="path_to_temp_directory" parameter if you need to change it. After each redeploy of web bundle jetty creates new directory.
Check jetty FAQ http://jetty.mortbay.org/jetty5/faq/...10tempdir.html

mccat is right - the temporary files are created either by the container, either by Spring DM web container for deploying the bundles. Unfortunately, even though we mark the files as deleteOnExit, this doesn't seem to work all the time on windows.
It depends on various factors - on my machine things get cleaned up though users reported the files are still left on the drive.

Feel free to raise an issue if this is a problem for you.
