Progamatically setting values of FORM elements

[Luc Foisy]

Is there any way I can have my java set the values of FORM elements.
Rather than storing the values in the java code and generating the complete form 
element containing that value.
 
Something like adding something to the response that will give that item a value.
 
For my particular need, I want to set a number of checkbox elements on or off. I do 
have the ability to predict the element names...
