I recommend storing these values in the attributes hash in the ServletContext object.
In JSP this is accessed through the implicit application object:
String thisString = (String)application.getAttribute("myString");
For servlets you would use:
String thisString = (String)getServletContext().getAttribute("myString");
To set these values I would recommend using the Deployment Descriptor so that at
deploy time these values are set. You can also set these in a Global.jsa file in many
app servers. I would stay away from this as it, to the best of my knowledge, not
present in the JSP spec (not 100% sure on that).
