    public prints() {     }      public prints(integer id) {         this.id = id;     }      public prints(integer id, string username) {         this.id = id;         this.username = username;     }      public integer getid() {         return id;     }      public void setid(integer id) {         this.id = id;     }      public string getusername() {         return username;     }      public void setusername(string username) {         this.username = username;     }      @override     public int hashcode() {         int hash = 0;         hash += (id != null ? id.hashcode() : 0);         return hash;     }      @override     public boolean equals(object object) {         // todo: warning - method won't work in case id fields not set         if (!(object instanceof prints)) {             return false;         }         prints other = (prints) object;         if ((this.id == null && other.id != null) || (this.id != null && !this.id.equals(other.id))) {             return false;         }         return true;     }      @override     public string tostring() {         return "entities.prints[ id=" + id + " ]";     }  } 

i tried use put method got error

and why didn't have post method in combobox?

controller code java ee 6

put request body part there.if going update entity should pass dto data should updated.i didn't go through link.this part can in json or xml.(like below)

 <?xml version="1.0" encoding="utf-8" standalone="yes"?> <prints> <id>1</id> <username>test</username> </prints> 

you have annotate dto lets printsdto below

@xmlrootelement(name = "prints")  public class printsdto { private int id; private string username; // have getters , setteres above }
