Selecting records in a jsp and displaying selected in another

Hi all
I display a few records on "one.jsp" with a checkbox in the first column.
The checkboxes have the same name while id gets incremented.
The data is in an ArrayList(total) which contains Beans so the rows get the bean.getXXX().
On submit of the SELECT button, i intend to store the selected records(beans of total) into another arrayList(selected).

I have looked up previous posts to find a solution to my problem suggesting the use of request.getParameterValues("checkBoxName") to get the selected checkboxes.

At the point where i check for action in my servlet i try to get the checked values but it is null.Am i missing anything abt scope(request/session) or something else needs to be done in one.jsp or two.jsp?
String[] checkedValues =req.getParameterValues("SelBox");

Can let us know what did you set for the checkbox values? If it's printing null it's not passing in the values from the checkboxes. Also can we see the whole code?


I'm not available, my BF's name is WORK.

Request and session scopes have nothing to do with submitted values.

By the way, about is spelled about, not "abt".


String[] checkedValues =req.getParameterValues("SelBox");


If your checkbox elements are named "SelBox", this will return an array of the values for any checked checkboxes. Note, checkboxes that are not checked will return no value.

If you are not getting any values for checked checkboxes, there may be something wrong with the structure of your form or form elements.
