Submitting form's data to a java Set

Question

Is it possible to submit a form\'s data to a java Set in an action of Struts2?

Action code:

class TestAction extends ActionSupport{

 private Set<         


        

Answer 1

The Set is just a collection, and Struts2 has support for any type of collections internally. But for this type of collection you can't use indexes in your OGNL expressions. Try

<form action="test.action" >
 <input name="mySet" />
 <input name="mySet" />
 <input name="mySet" />
 <s:submit />
</form>
