I'm in favor of c), because the business object should not know about
HTML, and separate result beans seem like overkill (in most situation,
I'm sure there are cases when they make sense).
An alternative to c), to avoid scriptlets, is to develop a custom
action that works like <jsp:getProperty> but that also formats the
value in an HTML friendly way:
<jsp:useBean id='customer' class='...' />
<h1>Here is the customer</h1>
<foo:getFormattedProperty name="customer" property="name" />
