How can i put a dynamic value to an ?

[John Antonakos]

I want to do something like the following:
<html:hidden property="firstname" value="<bean name="member" property="firstname"/>"/>

is this possible ?
The above statement produces an error.
Can i use another statement to do this thing ?
Give a dynamic value, coming from another bean,
to an <html:hidden> field ?
