Hi, Just enter your variables into a text file called abc.properties with name/value pairs, e.g
var1=val1 var2=val2 Although these will not automatically appear in application scope. You will need to write a tiny Servlet that you configure in web.xml, pass the filename as a servlet parameter, and set the servlet to load-on-startup=1. In your servlet, retrieve the filename and load the properties into a HashMap. Finally add it to the servlet context. Your application can now use the map from application scope, and better still, you can use it in JSTL syntax with $applicationScope.myprops['var1'] There are other ways but this is my recommended way.
