subrahm puvvada

i have ajsp file which which allows user to enter some data .
when u click submit button the values you are entered should be updated to the datbase.
when u call the same jsp file the updated values should be displayed

i have one situation
in jsp thereare values in the combo
and whenu select the value in the combo that corresponding values are displayed in table

sno field bolean
1 aa required here one checkbox will be there
2 aaq required here one checkbox will be there
3 aa c required here one checkbox will be there

when u select the checkbox that values areupdated in database.

up to this no problem.

when u call the same jsp file the updated values are displayed innplace of required.
for eg i fu check the yes should be displayed otherwise no should be displayed

i have one situation.
in jsp when u check items and click submit button the checked values are sumitted to the database.that i have done it
if u don't check any one and click submit button then server500 error is comming.
how to handle this situation

how to get the servlet version in jsp

String[] checkedValues= request.getParameterValues("checkit");
i have placed like this also
but the exception is comming

sorry i have given there stringarray only not string.
i have forgotten to modify and posted
