JSP - Servlet related question - Request Help

[Daku]

Could some Java guru please help ? I have a JSP, which calls a
Servlet, which in turn does some database queries, and then generates
a
Web page, in its 'doGet' method, and displays the retreived data. The
retreived data is displayed as a set of checkboxes with suitable
labels and all. By seelcting appropriate checkboxes, and clicking on a
button, the user
adds the selected item to another list. I was
wondering if there is a way to achieve the same something like the
following - the user simply passes the mouse over the items he/she
wants (no checking of checkboxes) and the items get selected. Any
hints, suggestions would be of immense value. Thanks in advance fro
your help.

There are several methods checking checkboxes with JavaScript, here is one:

<p>Please select a sport that you like to play.</p>
Soccer: <input type="checkbox" name="sports" value="soccer"
onMouseover="if (!this.checked) { this.checked = true; } else {
this.checked = false; }" /><br />
Football: <input type="checkbox" name="sports" value="football"
onMouseover="if (!this.checked) { this.checked = true; } else {
this.checked = false; }" /><br />

You could put checking/unchecking in a separate function also, for that
instead of "this.checked = true;" you should place a function call that
passes a checkbox number and the function would be something like:
"form.sports[checkBox].checked=true".

But nevermind that, if you want to write the changes in the database as
you hover your mouse over these checkboxes (without clicking a button) I
believe you should use Ajax.
