Take existing java application, refine and fix bugs2

Take existing java application, refine and fix bugs. This is what the java program does: - Takes data from mysql database. - Builds yellow pages style directory and "landing pages" for each of the elements from the mysql database. - Builds navigation on pages so people can navigate up and down the tree. The java apps is about 10 classes and well written. Not necessarily well documented. I can explain to you how to run that app and produce outputs. I can then tell you what needs to be improved to produce the output that is what we are looking for. Again, program reads from a mysql database, and creates about 50k pages. The pages are static HTML pages by doctor specialty / city. There are some issues how these pages are being created and we would like to resolve the problems through this project. Regards
