java - Exception converting object to XML using jaxb -


i trying build xml object using jaxb.

but missing because exception:

javax.xml.bind.marshalexception - linked exception: [com.sun.istack.internal.saxexception2: class employee nor of super class known context. javax.xml.bind.jaxbexception: class employee nor of super class known context.]

@xmlrootelement(name = "employee") public class employee {     private string name;     private string employeeid;        public string getname() {         return name;     }      public void setname(string name) {         this.name = name;     }     public string getemployeeid() {         return employeeid;     }      public void setemployeeid(string employeeid) {         this.employeeid = employeeid;     }  }  @xmlrootelement(name = "data") public class data {     public data() {     }      private list employees;      @xmlelementwrapper(name = "employeelist")     @xmlelement(name = "employee")     public list getemployees() {         return employees;     }      public void setemployees(list employees) {         this.employees = employees;     }  }   public static void main(string[] args) {         arraylist list = new arraylist();          employee e1 = new employee();         e1.setname("name");         e1.setemployeeid("1");         list.add(e1);         data data = new data();         data.setemployees(list);          jaxbcontext context;          bytearrayoutputstream outstream = new bytearrayoutputstream();          try {             context = jaxbcontext.newinstance(data.class);             marshaller m = context.createmarshaller();             m.setproperty(marshaller.jaxb_formatted_output, boolean.true);             m.marshal(data, outstream);         } catch (jaxbexception e) {              e.printstacktrace();         }      }

you need 1 of following jaxb (jsr-222) implementation aware employees property on data class contains instances of employee.

@xmlelementwrapper(name = "employeelist") @xmlelement(name = "employee", type=employee.class) public list getemployees() {     return employees; }

or

@xmlelementwrapper(name = "employeelist") @xmlelement(name = "employee") public list<employee> getemployees() {     return employees; }
