There are 2 combos. one combo contains Country, and another combo contains State of that country. My question is how can i change the state, after selecting the country, without reloading the JSP page.
How we can handle this in Action/EJB with JSP page.

you have to reload the page becaus the information in the second combo depends on the first.
You can manage this wiyh javascript but it's so complicated
