As you cannot inherit two classes, I don't think you can "re-use" this two existing tags code. You could create a new SumitTag instance to get it's code running from your tag, calling it's setters and doStart/doEnd methods, but I really don't think it's a good idea (I sometimes have very bad ideas).
IMHO copying half the code will not be so bad, as struts tag allready use common tools (RequestUtils...) and you will so have to learn using them !
