i have form jsp , on submit redirects success jsp. inputs form elements captured session attribute using value object , rendered in success page.the code goes follows,

form controller:

@controller @requestmapping("/userregistration.htm") @sessionattributes("user") public class usercontroller {  private userservice userservice;  @autowired public void setuserservice(userservice userservice) {     this.userservice = userservice; }  @modelattribute("countrylist") public list<country> populatecountrylist() {     return userservice.getallcountries(); }  @modelattribute("communitylist") public list<community> populatecommunitylist() {     return userservice.getallcommunities(); }  @requestmapping(method = requestmethod.get) public string showuserform(modelmap model) {     user user = new user();     model.addattribute("user", user);     return "userform"; }  @requestmapping(method = requestmethod.post) public string onsubmit(@modelattribute("user") user user,modelmap model) {     userservice.add(user);     return "forward:usersuccess.htm"; 

success controller:

  @controller   public class usersuccesscontroller {  @requestmapping("/usersuccess.htm") public string redirect() {     return "usersuccess"; 

user success jsp:

user details <hr> user name   : ${user.getname()} <br/> gender      : <c:out value="${user.getgender()}"></c:out> <br/> country     : <c:out value="${user.country}"></c:out> <br/>   : <c:out value="${user.aboutyou}"></c:out> <br/> community   :  <c:foreach var="community" items="${user.communitylist}" > <c:out value="${community}"></c:out> </c:foreach> <br /> mailing list: <c:out value="${user.mailinglist} "></c:out> 

but output is,

user details  -------------------------------------------------------------------------------- user name : ${user.getname()}  gender : ${user.getgender()}  country : ${user.country}  : ${user.aboutyou}  community : ${community}  mailing list: ${user.mailinglist} 

please help. in advance.

i think need add model.addattribute(user); in onsubmit method, because in view dont use form attribute
modelattribute="user"
if use form above attribute, dont need model.addattribute(object); because attribute somehow links onsubmit @modelattribute("user").
