Optional parameters in jsp...

[mendy smith]

If we want to make some of the parameters optional to my jsp page then i have set the required element attribute of that optional parameter in my ".tld" file to false right. If i have this set up to false then i can still have this parameter in my jsp page right. This set up doesn't work. How to make some of the parameters optional.
Can anyone please let me know.
Appreciate your help!
Thanks in advance!!
