What about something like:
<%
boolean checked = isChecked("a"); // check if the
value should be checked by default
if(showCheckbox(user, "a")) { // check if, for this
user, the checkbox should be visible
%>
<input type="checkbox" name="a" value="a" <%= checked
?"checked":"" %>>
<%
} else { // show disabled checkbox (or leave that out
to show nothing...)
%>
<input type="checkbox" name="noname" <%= checked ?
"checked" : "" %> disabled="diabled" />
<%
if(checked) { // don't need hidden value if default
is unchecked
%>
<input type="hidden" name="a" value="a">
<%
}
}
%>
