I need to write a JSP function that will efficiently convert an integer (from 1 - 3000) to a roman numeral.

Answer: 
Start simple. Work out how you would convert the numbers 1 - 9 into Roman. Code and test. When it is working correctly, extend it to handle numbers up to 99. Again code and test. When it is working correctly, extend it to handle numbers up to 999. Code, test and extend up to 3,000.
Google has quite a few links to both algorithms and code:
