we need some additional information about what you're doing!
How did you create the checkboxes? Which name(s) do they have?
Are you using an ActionForm or something like that?
Just show us a few lines of the JSP page where you create the form and the checkboxes...

In general, the name and value of the checkbox is sent as a parameter IF it is selected.
<input type="checkbox" name="delete" value="12345">
<input type="checkbox" name="delete" value="67890">

You can then call "String[] toDelete = request.getParameterValues("delete");

If both are checked, you get an array with two elements, if only one is checked, you get an array with one element. If none is checked, I'm not sure, I think you get null.
Unfortunately, it is very hard to find out which checkboxes are NOT selected because they don't send any data to the server...

I don't understand your question about additional parameters... You can just add them to the form as hidden fields...
