I'll give it a try, thought I can't imaging how cygwin would have locks unless you cd'd into your expanded war or opened files there. > If you're a UNIX person, then this is not going to be as comfortable as > running > Cygwin, but it will remove some unintended consequences.

I might try Eclipse, but we have 20 webapps running on 11 tomcat servers, and one login server must always be running, so it becomes complicated. > Some quick notes on your web application (which I don't think will affect its > loading and unloading): > 1.
