Calling a method

Here is a subquestion to a post I made earlier:

given integers x and y, what is the syntax to send them to a servlet called Logic.java to its method doGet(), using the command in a jsp page, onChange( )?  The onChange command is embedded in each of a series of dynamic dropdowns in the select tag in the jsp page, populated by a for loop.  The method doGet( ) will contain a query that will check the logic of the dropdowns to determine population.  Please use laments terms as much as possible, my javascript and servlet skills are lacking. ;)  Thanks!

when you use onChange(), you are using javascript. so you must use javascript to either 1) send the parameter via url or 2) post the form to servlet.

but as you indicate you one doGet in server (while i don't know why because you can easily make servlet access doPost ), you can only use option 1.

you should call this in your javascript:
var x=123;
var y=456;
location.replace( 'urltoyoursevlet?x=' + x + '&y=' + y );
