jsp - Submit <s:radio> tag selection with different attribute from the one being displayed -

for sake of simplicity, define scenario as: class person defines object id (int) , name (string) attribute. created list<person> persons, loaded jsp page respective action class method (getpersons()), populate <s:radio> tag. far, good, jsp populates <s:radio> accordingly. can select , submit option action class (defined in jsp's <form> element). problem can submit name of selected person in <s:radio>, when want submit person's id. how can it?

practical example: have 2 persons on <s:radio> list, john (with id=1), , peter (with id=2). want display names on <s:radio> element, if choose peter, want submit 2 action class, instead of name.

code below:

jsp

<form action="submitdata" class="ink-form all-100 small-100 tiny-100" method="post">     <s:radio label="persons" name="personid" list="persons.{name}" /> </form> 

action class (submitdata action)

public class submitdata extends actionsupport {     private string personid;      public string execute()     {         system.out.println("person id: "+personid);          return success;     }      public void setpersonid(string personid)     {         this.personid = personid;     } } 

in ognl persons.{name} called projection , don't need in <s:radio> tag. use listkey , listvalue attributes define property of objects inside list shown , submitted.

<s:radio label="persons" name="personid" list="persons" listkey="id" listvalue="name" /> 

one more thing. person id int , trying submit personid string. of course work consider changing personid int. in way, later when want retrieve person object database don't need convert string int.
