Well, your problem is that you did not clearly tell us what you have and what you need.
OK, the 'need' part is OK after you ask a totally different question the first time. However, we don't know what you already have tried (if anything), nor do we know which jdev version you use. This would help solve the puzzle for you. Still you can't expect us to do it all for you.
You should get hold of the skin editor for your version and you have all tools at hand you need fro this task.
If you have a specific question you come back and ask it here.
