I am new to JSP and servlet for 1 month, and there are many things that I am still unsure off.. Inside a JSP, I have a dropdownlist(the values inside are grab from database) and it would be dynamically created on the number that the user keyed in. Example, the user key in 3, this digit would store in session, and 3 dropdownlist would be generated.

I am able to do this, however I am unable to grab the value of all the 3 dropdownlist in a servlet. and instead of getting 3 diff values, the output repeat the value of the first dropdownlist. Example "john,john,john" instead of "john, ken, andy".



Can i set the downdownlist name like "list<%i%>", to set different id to each downdownlist? therefore i can retrieve each of them seperately???
