Hi
I have
attached Pasted the code which solves your
problem.
Logic: On Click of the button, call a javascript
function.
In
the function,
Iterate through the select box and find out if the values are selected. If
selected added it to a variable.
In this way construct a comma seperated values (CSV) of values selected in the
select box.
Now pass this comma separated value to the
servlet where you can get back the values by StringTokenizing with comma as the
delimiter.
For your Information: Javascript does not
support string array. So you have to use a CSV values only. You can change the
delimiters to #, $ etc., whichever you feel
convenient.

valInSelect = valInSelect + "," +

I have a text box for putting a value, a "add" button for adding this value to the list (multiple select),
and a "remove" button for removing value(s) from the list. I guess the question is how do
I convert the content of this list to an array so I can pass it to the servlet...or...I am not sure if
using a multiple select is a right choice. The only reason I use a multiple select list is so
I can remove more than one value from the list after adding values incorrectly.
I can make it work only if the values in multiple select list are selected (...of course). Do you
know a way to make the values in the list "selected" by default? Thanks:)
