Hi, i am currently reading up on delegating as much processing as possible to
javabeans components hence i have come across various beans regarding html forms
ie <html:select,html:option, logic:iterate etc etc . Pls could anyone explain or
advise were one can get an understanding on selection to the desired form bean.
Cheers chuck
