AFAIK there is no general advise where to put dynamic, persistent data. As system administrator I prefer solutions that give me the opportunity to decide myself where to put dynamic data. There are a lot of reasons for this: securing against disk space overflow, backup, priviledge separation, etc. Following this way you might create a "properties-"file outside the Tomcat-hierarchy at a sensible place (e.g. /etc/app.properties) with the paths your application should use. Another way is to define a Tomcat-parameter during JVM-startup that will contain the path to your data-directory. As this might not survive the next update of Tomcat itself I don't like this kind of configuration but some applications and classes are working this way. > My goal is to find a consistent way of creating persistent data > relative to the context.

Of course there is always the danger of accidentally erasing the data by re-deploying this pseudo-application. And you will have to find a way by valves, etc. to preserve this path from being accessed by web-clients. Maybe it is enough if you leave out the context-entry.
