Why would you do that? ECS is just as good as having HTML inside
out.println() all over your code, but it looks uglier :).
take a look at that
<form action="">
#foreach $ad in $ads.getIds() #begin
<input type="hidden" name="ad" value="$ad">
address <textarea name="address_$ad">$ads.getAddress($ad)</textarea><br>
description <textarea name="description_$ad">$ads.getDesc($ad)</textarea><br>
close to train station <input type="checkbox" name="close_1_$ad"
$ads.getCloseto(1,$ad)>
close to church <input type="checkbox" name="close_2_$ad" $ads.getCloseto(2,$ad)>
...
#end
<input type="submit">
</form>
Of course you could use a loop to create the checkboxes too if you wanted.
You are right about the second part. You use String[] ids =
data.getParameters().getStrings("ad");
and then search the parameters for names ending in particular id.
