Java: how to write to folder in webapp?

Question

I deployed my webapp in Tomcat, but when I prefix the filename with \ I end up in the root of my server (C) folder, and if I don't prefix it with \ I end up in the bin folder. The former I expected, the latter I didn't. What's the cleanest way to write to a folder in my webapp(userControlWebApp\images) because just doing ..\webapps\ + request.getContextPath() doesn't seem the cleanest way.

Can't you use an absolute path?

That's well so absolute... I like to keep it a bit dynamic.

Use getServletContext().getRealPath(..)

Can't believe I forgot that one. Just tried System.getProperty("user.dir") and that also seems to work. Any reason to use one over the other?

prefer the API - getRealPath. I'm not sure if the other is guaranteed to work always.

Note that the folder and all its contents will get lost whenever you redeploy the webapp. It's not a good choice if you want to make it permanent. See also this related question stackoverflow.com/questions/4548190/…
