Hi all,
i need to find a replacement for the *.property file.
because, if we update a property file, we need to restart the server. So, i need to find a method, where i can change the property values without restarting the server.
I am using java 1.4 and the server is web sphere.
need help from you all!
thanks!

Why? Could you not just poll the properties file for changes?

Write a timer task (or something simmilar) that checks the porperties files periodically and reloads them if they've been updated (perhaps by keeping track of the modification dates or something).

Hi,
Another option is to use the Apache Commons Configurations library. It supports runtime reloading of property files, and even modification of property files.
