This should run independently of any webapp. Other things to consider are: 1. How often you actually use the AWT 2. How often you hot-re-deploy your webapp For instance, if you hardly ever use the AWT, then perhaps you should have an external process that handles this operation. You could maybe use a batch job, or even spawn a command-line program that does your dirty work. If you use the AWT a lot, perhaps an "AWT server" is what you need... sprinkle a little localhost-only TCP/IP into a separate process that runs independently of Tomcat. This could be a long-running process that eats up only its own memory and not that of your webapp. Finally, if you hardly ever hot-re-deploy your webapp, I just wouldn't worry too much. For exmaple, whenever we upgrade our apps in production, we shut down Tomcat and the JVM entirely, load the new code, and start back up. In that case, the re-deploy scenario isn't an issue (even if it's true that re-deploying "wastes" memory). Personally, I would be leery of running an AWT instance within a production webapp, simply due to the memory and CPU consumption issues it raises. I'm sure that it's way more stable than it used to be, but it's hairier than the hashtables-and-JDBC world of the standard webapp. Just my two cents. - -chris -----BEGIN PGP SIGNATURE----- Version: GnuPG v1.4.5 (MingW32) Comment: Using GnuPG with Mozilla - http://enigmail.mozdev.org iD8DBQFFU7x/9CaO5/Lv0PARAoQqAJ9dDZyVRq+tlJL21y0tWo7YbjVcdACfakG4 fiZmOVBfTqTfe79V7S4NJNw= =Gz8X -----END PGP SIGNATURE----- --------------------------------------------------------------------- To start a new topic, e-mail: users@tomcat.apache.org To unsubscribe, e-mail: [EMAIL PROTECTED] For additional commands, e-mail: [EMAIL PROTECTED]
