I have a req that everthing be within a single jsp file. The page takes in as a param a number and I need to map it to an image. I know i could do it with a huge if statement but there has to be a better way.
You could have a string array, or a map, for example. But your question is about Java, isn't it? The fact that it's going to be dumped in a JSP page as if it were still 2003 is not particularly relevant. So let's move this to one of our forums where questions about Java are answered.
