Subject How to convert request parameters into Collection type - Set
Date Wed, 20 Jan 2010 14:08:42 GMT
Hi,
I need help in mapping JSP text fields to a setter in action class which  have parameter as
Set<String>

I know Struts 2 supports automatically converting sets of request parameters into properties
of various Collection type Lists
This can be done by having a setter in the action class as - setMiddleNames(ArrayList<String>
middleNames)
JSP code should contain text fields as follows:-
<s:textfield name="middleNames[0]" label="middleNames"/>
<s:textfield name="middleNames[1]" label="middleNames"/>
<s:textfield name="middleNames[2]" label="middleNames"/>

Question :- How to map JSP text Fields or Hidden fields to setters in Action class which have
parameter as Set<String>

For example, how should I define text fields in JSP so that they can be mapped to the following
setter in Action Class:-
setMiddleNames(Set<String>)


Thanks,
Nitin Mittal
