I am not sure how you want to use the list: you want to display that list to the screen or you just need it as configuration. To display it you could:

• create your list statically in your Action, then display it in the JSP
• you could take the list dynamically from a database, then display it in the JSP

To use it as configuration: some data can be made available at application level at initialization, but those are configuration params. More info here:

Using the ServletContext is the only way you can set parameters dynamically to the servlet from your code: servletContext.setAttribute(). More info here:
