Agreed, but use care with the something. While, the servlet spec specifies a return value of null for getRealPath() in a war deployment, it is my understanding that at one time all of the containers did not implement this consistently. I haven't looked recently, but I would suggest checking the major container vendors to ensure they are compliant with that rule before using an if statement on that null.
In the J2EE environment, while you can't have the threads, could you use the new timer stuff to accomplish checking to see if the file has changed?? LES -----Original Message----- From: Anthony Eden [mailto:[EMAIL PROTECTED] Sent: Wednesday, June 11, 2003 9:30 PM To: [EMAIL PROTECTED] Subject: Re: [OS-webwork] Configuration in /WEB-INF Read my original message again: this is a problem which exists for loading resources through both classloaders and the servlet context. If you want something which will always work then you must use interval reloading. However this means that you have to have a thread which is running to load the resource at a regular basis and this too can be a problem if you are running in a J2EE container. There is no good solution at this time, i.e. nothing provided by the APIs, but you should probably use something (or at least give users the option to use something).
