I have tried posting this question to comp.lang.java but I didn't get the answer that I needed:
I am writing a web application that stores its data in an XML-file. I am deploying it via Apache Tomcat. I would like to make it easy to deploy. For it to work the user deploying my application has to set the file name of the data storage.
I can think of two approaches:
1. The application provides the user interface: My application has a setup page and if it is the first time it is run it will ask the user the file name of the data storage.
To implement this I need to make a string persistent. Does Apache Tomcat provide a way to make data persistent accross stop/starts? I have tried setAttribute in ServletContext but the attributes disappear when the application is reloaded.
2. The servlet container provides the user interface: I find the Tomcat web interface slightly clumsy but there is something called environment entries in the administration tool. How do I read these environment entries in my application?
Alternatively: Is there a way to set the init parameters (that are read via ServletConfig) from within Apache Tomcat's web interface?
Any help appreciated.
