Hello,
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.

for instance

String path = "";
if(num == 1)
path = "people.jpg"
else if(num == 2)
path = "sun.jpg"
else if(num == 3)
path = "moon.jpg"
....

and so on for about 50 images

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.
 
I agree. Here's the link: http://aspose.com/file-tools
