Just to clarify, let's call the person deploying your application the server administrator (this person has access to server.xml / the tomcat admin/manager webapps), and the people using your application the users. >To implement this I need to make a string persistent.

No. Webapps don't supply persistence. You have to do it yourself, e.g. using a database or configuring a file resource. >2.

How do I read these environment >entries in my application? See: http://jakarta.apache.org/tomcat/tomcat-4.1-doc/jndi-resources-howto.htm l This is probably the way you want to go. The servlet administrator will define the appropriate resources in server.xml. You just use the <env-entry> in your web.xml. That way you distribute the same webapp war to everyone. What this JNDI entry point to is up to you: provide instructions to the server administrator on whether the app will want a file (I suggest this to start with) or something else (e.g. a DB into which the app can write).
