If you have a from which uses GET when submit the form, the string will look like this:
A html tag can have these words inside:
TYPE
NAME
VALUE

You can name your textbox as TXTBX and the text area as TXTAR and getParameter("TXTBX") and getParameter("TXTAR") will return what you are looking for.

Oh, I've made a little mistake in the previous answer. Anyway, few more details:
getServerNames() retrieve all the names you have and it hasn't any parameter, as mohan said.

Hi,

     I'm sorry. It should be request.getParamaterNames() rather.

You cannot get the type of the Object - viz whether TextBox or TextArea from inside the JSP, which has got the results from some form from other page. The type is a property of the form and is available only via JavaScript / DHTML on the same page only. You may add a variable to the form (of TYPE="hidden") which will hold the value whether the type of the form-input object is TextBox or TextArea.

Hope it helps.

sigh..

since im using the same name for textarea and text box (and using POST method since i have tons of form elements),
obviously the result of those getWhateverMethod() will be the same. anyway i just made a workaround by counting the string length hehe :)
