I have a html form as shown above. When the user selects a check box and chosses a option from the drop down ie either reverse or correct,the user should be presented the reverse.jsp with one row of values which the user selects.If the user selects two checkboxes and chooses reverse from the drop down then he should see two rows of data of the selected ones in Reverse.jsp.
I would like to know as to how to do it. Also in the jsp page i would like to include a javascript that highlights the selected rows.A code for doing this would be appreciated.
Thanks

Try use:

if ((request.getMethod().equals("POST")) {
//change your HTML here
//Use request.getParameter("ControlPanelOne"), as well as request.getParameter("checkbox1") and request.getParameter("checkbox2") to determine what values had been posted.

}
else {

//Show Original HTML here

}
