I don't have to write to a file, as long as I find a way to persistently store the changes and make sure they take effect after a restart. How would I be able to change the static variable on the fly, say through a command line in unix?

What can i use to do this? or >is there a better way? There are many ways ;) Do you HAVE to write out to the file, or can you just change the value in memory? Typically when you want to do something once on startup you do it in a ServletContextListener. Make the variable static and add static accessors for your variable in your context listener implementation. You can specify the configuration file location in web.xml as a context-param, or you can specify the starting variable value itself if you don't need a text file. If you are using a text file and want to write out the final value when your app/server is shutting down, you can do so in the contextDestroyed method of the listener.
