It's generally a bad idea to ever *write* into the webapp deployment space.
You have no guarantee that the space is writable, nor that the container will
provide any write access. You're much better off writing to files outside of
Tomcat's directory structure, where the path can be provided by system
property, environment variable, <init-param>, or whatever.

Or anywhere else in the webapp's structure; it's not confined to WEB-INF.

Using ServletContext.getRealPath() is risky; the container is under no
obligation to provide access to the underlying file system (think deployment
via .war file). Much safer and better to use getResourceAsStream().
