Thanks a lot, Kirs. I have tried your method, it still can't show image when use wan connected. I have no idea about how to change the env so that the app can create and write to "generated" or temp-dir, can you give me an examples for windows 2003 server.
I have checked our app, it can create chart png at tomcat\temp with jfreechart, maybe we could change the env so that app can use it or app\generated dir. I think both your method or our app could show correctly because our server disable some user account or rights, so we can change some env for the dir such as "generated" or "app", and can still safe? More help, please!
