Yes the name is important, but I have to change my previous statements a
little.
Using the one from online doc
public FooForm extends ActionForm {
private final Map values = new HashMap();
public void setValue(String key, Object value) {
values.put(key, value);
}
public Object getValue(String key) {
return values.get(key);
}
}
<html:text property="value(foo)"/>The key of name matching is
property="value(foo)" will trigger invocation of setValue(foo, ) and
getValue(foo)The name matching pattern is property="xxx(key)" matches
function setXxx() getXxx()
The example you give is ActionForm to change java beans.
But set/get values from type Map doesn't fit into the bean coding
convention. That's where map backed ActionForm come into play in struts1.1
